Hi there, I'm just started to get into Xgenerative Design this month and it´s quite hard for me to catch on. My main topic and for what I'll use Xgenerative Design most will be to create patterns on surfaces like this one for example:

2 years ago, I made a try with a Penrose tiling. I kept bothered because the modeling was too complex and impossible to explain. I posted it anyway for the result only. Here is a reboot of the study, with a much better visual scripting app, no "user defined" feature and my better understanding of the logic for a short modeling. I was able to go a little further, up to P3, which is the rhombus tiling. but this will be for another post. overall size of the current modeling -> I think it is short

Hello All, How can I define multiple Assembly contexts Parts (3dp) or Bodies as inputs? BR.

I missed the Travelling Salesman function in tab "geometry" and section "others" with a cool icon. it helps in many things like manufacturing, logistics, and robotics to optimize the path of drillers. and when tired to drill, it could be used for some cool art (Robert Bosch). it also helps to express one's feeling.... here is 2D, but applicable to any surface logic of the model import a picture surface sampling and stippling then Travelling Salesman Big thanks DS RD!!

Hello community, Can you add a predefined list of AEC Types as input of Define Specification command? Finding the right syntax becomes a game of chance... @FL Thanks

description : Simple model and sequence to learn how to use CATIA Visual Scripting + CATIA Lattice Design. Here the idea is to create a lattice unit associated to a simple square surface, and then use the "Wrap on Surface" operator (enabled by CATIA Generative Shape Morphing) to distribute the lattice unit on a quad surface, and finally prepare a list of 2D lines to be used in CATIA Lattice Design thanks to the "Lattice Specification" Operator. prereq : CATIA Visual Scripting CATIA Lattice

Hi all, I would like to model braided asd occluder, I am a beginner in 3dexp. I am attaching the photo of the braided asd occluder to be modeled. Please let me know where I can get some tutorial on this , so that I can build up on that. It would be grateful, if you help me in this regard. Thank you in advance.

Hello, I'm struggling to get the attributes Length, Boolean, etc from the published parameters in an EKL script. The Find and Query Methods works as intended but GetAttributeString, GetAttributeReal, GetAttributeBoolean returns nothing. Is there a secret somewhere or I am just missing something ? Thank you for your time, Rémi.

Hello community, I'm struggling to install python packages and find which folder of package i need to bind. I just wanna use numpy package of my script in visual scripting. thanks

Dear All, I'm having trouble with the Visual Scripting Editor—after the message "Loading In Progress", nothing happens. No error, no crash, just no response. It seems like it's just affecting me, so I’m wondering if anyone has faced this before or has suggestions to fix it? Thanks in advance! Kaverikannan S

Hello everyone, I have a quick question and was hoping someone might have a workaround for this issue. I'm currently working with external parameters that come from my design sequence. These parameters are used in a drawing to define certain rules. Now, when I modify the parameters in my 3D model, the changes do reflect in the model itself, but the external parameters are not automatically updated. As a result, I have to manually update the entire assembly, then switch to the drawing and update

What am I missing so that the watch node will display values in the Monitor section?

This study is to illustrate the function circle packing from mesh with its added options 25xFD03 (partial and Gen mesh). now, with this function I get a triangular mesh with tangent incircles and in addition get easily the projection of the pedal centers of the triangles and also the modified (more harmonious) triangular mesh and its edges It is important to model the soap film effect already, like few months ago. This time, I made a try on smooth transition from a triangular mesh to its dual.

Hi everyone, I would like to generate a regular 3D volumetric mesh (e.g., tetrahedral or hex-dominant) from a solid body using Visual Scripting. So far, it seems that meshing in Visual Scripting is mostly limited to surfaces. Is there any way to generate a true volumetric mesh similar to what is available in Structural Model Creation, with control over mesh size and geometric deviation (sag)? I’m specifically looking for more predictable and controllable meshing than Voronoi-based structures,

Hello Everyone, I have a series of nested scripts, that output from one script will be the input from next script. I am experiencing an strange problem, that whenever I drop a node in visual script ,lets say "distance", before even adding any inputs to it or before it having any affects at my published geometry in the script, other scripts in my product start refreshing, and it takes lots of time. Wondering if this is a bug or a setting issue?

Hello, Last update of Chrome introduces issues in xGenerative Design. Since the Chrome browser update to version 138 this week, we've been experiencing a display issue from CATIA xGenerative Design in “Monitor” panel. The information normally displayed in this panel are no longer visible, but can still be viewed from the Graph Editor. If your Chrome version has been updated and you're experiencing this issue, you can temporary use another browser such as Firefox. Edge browser is also

Hi everyone, I’m trying to generate a 3D Voronoi lattice using Visual Scripting. I would like to gradually increase the density of the seed points along a specific direction (e.g., the Z-axis) during the Volume Sampling operation. Is there a recommended way to apply a directional density gradient or probabilistic filtering during sampling? Ideally, I’d like to have fewer points at the bottom of the part and a higher concentration toward the top. Any tips or best practices would be greatly

Hello, I need to create a powercopy of a sequence with a 3D text. For an unknown reason, the font (which is a standard one I suppose) from the original isn't applied in the copy. The box still refers to the correct font but the preview is missing and the font applied is another one. If I create another font box, the original font is correctly applied. Has anyone encounter such a behavior ? Thank you for your help, Rémi. Original Font box : Wrong font applied New Font box in the powercopy's

Hi, I'm trying to get the name of different geometries in my model. For example, when I select a geometry (in this case, a line), and then try to access its name using the "Attribute" node, it returns something like QueryChildren.8 instead of the actual name shown in the model, which is "KW_2". I've also tried using other attribute types, such as "Feature", but without success. Could someone help me to correctly access the geometry's actual name, as shown in the model? Thank you and

Hello, In Visual Scripting, is it possible to create voxels from different geometries and perform Boolean operations on them? Or can voxels only be created from total space, and Boolean operations performed between other geometries and voxels? Best regards, Ayda

Hi, I tried to distribute points via 'Rectangular Grid', but it wouldn't accept offset surfaces as inputs. I offset a surface and wanted to define the output (two surfaces) as a list input for 'Rectangular Grid' (1), but an error message appeared saying that the input plane could not be evaluated using 'Geometric Surface' (2). However, as can be seen, I used a geometric surface as one input for the 'Rectangular Grid' node and it worked (3). The help section for this function also says that these

Hi, Is there a node that can convert a 'Dimension' into a real number? I’ve already found a node that does the opposite — converting a number into a dimension — but I need one that works the other way around. Thanks in advance!

You can download from here 2 files about windshield pattern with CATIA Visual Scripting.

Reference on Perlin noise, just in case Use case 1: Dissolving sphere Perlin noise: octave = 1 and frequency = 2 over the entire space the conditions are points are inside the sphere or radius 23mm => does not touch the space boundaries points do not belong to [-0.1;01] Car Paint Plastic Wood like a dissolution with video generation points do not belong to intervals from [-0.05;0.05] to [-0.7;0.7] VIDEO What if? points are inside the sphere or radius 23mm => does not touch the space

Hello All, Im facing some challenges on shape fillet operator. Im trying to add fillets between the revolute surface and base of the pitch. Not sure why Im getting errors. (Tried with minimal radius) Thanks in advance!

my goal is to visualize GGR Perlin noise in 3D. I want to make a surface or volume out of it and play with its inputs. Perlin noise outputs a list of Real values out of a list of points in space. So in the end, I get a 3D field of scalars! A way to visualize them is to use Marching cubes that will convert my scalars into connected polygons and then you can do whatever you want, like a mesh or surface or volumes. this post is about my way to implement marching cubes algo. in future, I would

Hello CATIA, MODSIM and SIMULIA users, In this webinar, we will talk about best practices to drive the structure design of EV’s battery-carrying space. It is an innovative MODSIM approach where Visual Scripting allows design automation and Concept Structure Analyst allows end-to-end process automation. Here are some of the highlights to look forward to Agile Modular Design definition and enhanced design resiliency to any input change Unified, scalable, and associative MODeling/SIMulation

Hello @TV @FL, In visual scripting how can i get the 2d curve of an horizontal alignement from civil engineering? Even if If i get the right type of the object (AECAlignment2DHorizontal), visual scripting don't recognize it as a geometriccurve. How can I solve it? Thanks

Hello @TV, Apparently Is Inside command doesn't support polyhedral objects. Can you confirm me this limitation or I don't use it properly? Thanks

When creating a Point on Plane, it is possible to click-and-drag the point anywhere on the support surface. Is it be possible to expose this behavior in a controller? If not, it would be very useful. I have a project where I would like to create xGen design sequences for non-designers. These users would largely work with the software through the "Experiment" tab. Being able to locate a point instead of manipulating dX and dY values (even using sliders) would be great for end users. I have the

Hello all, I have tried this workflow across two different models on both Firefox and Edge with the exact same result. When I select the "Import New" button for Read Sheet, it crashes my xGen session. The "Use Existing" option seems to work, but I don't have the desired CSV already in a collaborative space. Is there anything I can try, or should I just file an SR?

Hi Visual Scripters, Our last R2025x FD02 update was deployed last week on the cloud platforms, with a lot of new features for CATIA Visual Scripting and xGenerative Design. As usual, we hope that you will appreciate this update and we would like to have your feedback (don't hesitate to add comments to this post, we will be pleased to read all of them), and stay tuned for next communication update. R2025x FD02 As a reminder, "What's New" and other documentation resources are also directly

In CATIA Visual Scripting, additional "advanced operators" are accessible for algorithmic design (depending additional roles and apps). Important : specific apps must be granted and installed to access advanced operators in CATIA Visual Scripting. More information and details on all advanced operators in the dedicated User Assistance webpage :

Hello, @ES @TV In my workflow, reach target works well with an exact volume but fail with a polyhedral. How can I use Reach Target command with Polyhedral objects ? In Civil Engineering industry, most of the volumes are polyhedrics and we need this capability to calculate concrete pouring. Thanks

Hello, There is a Structure tab on-premise, but not on cloud. The roles are the same. I'd like to know why.

Hello everyone, Let me share with you a tutorial/demonstration showing the capability (since 2024xGA) of User Feature (UDF) instantiation in Visual Scripting. With this feature we can combine the best of Visual Scripting and Generative Shape Design (GSD). Unlocking new complex feature pattern possibilities Saving time with detailled design automation without needing to write code In this demo: We use Visual Scripting to create an automated process to instantiate a boss user feature without

I made a study on how to make a Gyroid which is a minimal surface used a lot when additive manufacturing is OK. there is a built in function int CATIA for additive manufacturing preparation 22mn40s + use case https://www.youtube.com/watch?v=oKylME0JhYc Beyond value for industry, it is a nice surface and it is cool to understand it (I think). A minimal surface has its mean curvature = zero. So, in any vicinity on the gyroid surface, it is like a saddle! (everywhere like a saddle shape) A

Hi everyone, what role do I need for making mesh in Visual Scripting Editor native app? These are the tabs that I have to choose from in Visual Scripting Editor (picture below). This are the tabs that i can see in xGenerative Design on web app (picture below). Do you know how to add mesh tab to Visual Scripting editor native app? Thank you

Hello, Please find here an example on how Visual Scripting can be use to find the best angle for a part to minimize the waste of material during a progressive die process. Yield rate is the ratio between "Actually used material" vs "Raw material from the sheetmetal strip" As the criteria is purely based on geometry criteria and quick operation it's very easy and fast to test all the rotation angles within VS and find the best one without having to go through powerful tool such as Parametric

Please find the replay of the user talk on the video right below: Dear CATIA fellows, It is a pleasure to invite you to our next CATIA Design User Talk, on March 25 at 10:00AM CET. This time, we will dive into the fascinating world of aerospace design by discovering NTNU Propulse, an autonomous student rocketry team from Norway. They aim to reach space with a self-developed liquid-fueled rocket, that already reaches thousands of km/h in seconds! They experiment beyond theory by working on

Hello, I am facing an issue that is really troublesome and makes me wonder why is it happening. I am working at a Facade design company and i used xGen sequences to create facade patterns for a project in Amsterdam. The Xgen generates various publications that are used by the EKL script to instantiate UDFs for client approval. Everything was fine till yesterday, today i opened my script again and this happens: No matter what i do, the script doesn't respond. Global refresh, solving the

Team. I was trying to drive a GSD sketch with a normally defined parameter named "Length.1", unknowingly there exists a parameter of identical name in a Visual script block. 1. When I try to double click the tree to drive my sketch dimension with the value of the parameter i want (295mm), ..... 2. Catia instead grabs the parameter "Length.1" from the Design sequence with the same name/label. eeeek!! I think this is a pretty nasty bug??

Hello, I'm experimenting a problem with UDF in a visual script. It worked until now (this script), but since one week, there is a problem with it. The interface is very long to open, and the height of the popup grows every minute, repeating the lists of input and output. Thanks in advance Thomas (I don't know if it's the good place to report some bugs...)

I have an issue with a shape fillet where VS is giving me an error message, but if I publish out all of the input geometry and parameters that create the shape fillet and manually create the shape fillets in GSD - they all work without an issue. Manually created Fillets in GSD no issue:

Hi all, I was creating this feature and found that for a simple case i have it only works at a ratio above 0.57 For anything < 0,57 i get a strange result. Thoughts? Thanks

Hi all, was hoping to derive some UV curve geometry from a flat surface fill surface, however I notice that fill seems to create 'trimmed' surfaces where it 'could' create an otherwise simple flat loft. Thoughts please ? Thanks

Is there a reason for the VS Shape Fillet to be missing the Extremities change that is available in the GSD Fillet command? Would be great if the VS Fillet includes Extremities Pick like GSD Fillet (Smooth, Straight, Minimum and Maximum). I also could not find a tritangent Fillet command in VS.

Is there a trick to feed in additional geometry (keep the additional geometry pick open long enough to pick it). I am trying to feed in multiple geometry but the pick swaps too quick from additional geometry 1 to geometry 2. I don't seem to be able to pick the additional geometry 1. Any button combination to keep the pick longer open?

Hi guys, This is a work i am doing for company and i have to publish the surface with names corresponding to the type. As you can i see, I have done multiple checks to see which panel is which type, color coded them and then changed the name using "set attribute". but the changes dont get reflected in the published items as you can see, only the bottom panels names got changed, How long does it usually take for Xgen to process this?

Hello. So I am trying to rename certain surfaces that I have created in X-gen. i am not entirely sure how set attribute works. I have created a dummy script for now to see how it works. How can I make it work? The end goal is to change names of different surfaces and their corresponding axis systems that are published at the end of the script and will be later used on for the UDF and enigneering template instantiation.

Hi everyone, How can I increase the window size in Visual Scripting ?

Hi there, I am using the Swepdraft and can't make it work to go from a start plane to an end plane. as you can see below, I use 2 planes to have a start and an end to my surface. I have set the modlns to UptoSurface But the created Surfaces is clearly cut at the curve and misses one side! Anyone else has the same issue - is that a bug?

All, I have a honeycomb solid shape where I want to fillet all the vertical edges, except for the internal tangent ones and the ends of the ribs. I found and filtered out all these elements to get the list I want to fillet but when I choose the support and even just a single edge which it should fillet easily, it's failing. The edge selection and filtering support solid all correspond.... any ideas? Thanks

Hi, We received few questions regarding the possibility to use "laws", like in CATIA Generative Shape Design (GSD). It's something already supported in few operators such as "parallel curve" and "sweep draft". In this 3DXML (to download), you will learn how to use "function editor" for it. It's also possible to use the "Create Function" node, based on an expression (like 3*cos(x)+2) for the same purpose. 3dxml to download

This is a study following a question of @BK on how to make a soap film like this. picture fom Colloquium_Soap_bubble_clusters.pdf attached below A soap film follows some rules, which are the plateau's law In very short, from graphs of planar soap bubbles.pdf attached at the bottom The Soap film consists of one-dimensional curves of constant curvature; that is, circular arcs or line segments that do not cross each other. At each endpoint of one of these arcs or segments, exactly three

Hi brains trust. When a Publish node is replaced with another for same resultant geometry I understand this is kind of like changing a something in the GSD realm and need to repair the children of that feature is a given. What tips do people have to make this as easy as possible? In the case below, 'Translate.2' takes Publish.1, but if I connect (replace it) with Publish.2, Translate.2 will error due to a missing parent. Now obviously I'm familiar with the parts' design logic and know what was

I note that it's not possible to interrogate this via traditional methods? Any tips on how to more easily do this? I would have thought given the input definition is succinct that Parents Child would work. One must 'open' the sequence, then click on each input to see what highlights in the tree, In a large model this would be cumbersome and somewhat annoying. Even expanding the DS and clicking an input doesn't highlight it or allow you centre or re-frame on the geometric object.

Hi all, I was playing about with extracting parameter values from geometry and in my case I have point with additional params attached to it reading that value and creating a 3D tag with said value. However.. I find that the only way to get the tag note to update on a value change of the param value (which doesn't always mean a point change), is to modify the point in some small way such as changing it's X value for example. Is this expected or a bug? If i do a "force update" update on the

Hi All, I’m experiencing a graphical issue with the fine sweep regions, where the sweep diameter is about 0.04 and also the entire length is 4mm. Can you confirm if this is a graphical issue? Also, is there a direct operator in GGR to check for interference in these spline sweeps?

Hi all, so was playing about with reading and writing to existing params on an object, in this case a point. The moment i connect the VS connector from Real.1 with value 3 to the val in the set attribute block it wipes out/deletes the existing string parameter (HoleString). Am i doing something wrong? (another beginner question). Thanks

Good morning guys! So I am new to XGen on Catia platform but I have a good base with Visual scripting as I have worked on Grasshopper, which is an opensource software. My doubt lies here: I have created a facade pattern which has a set of rules and principles to randomize the configuration but also keep the unique panels in a range of 200mm to 3520mm length wise. The Architect wants it this way. Right now, Out of the 512 panels on one side of the facade, 228 panels are unique length-wise, but

Hello, I have been trying to use Remove Index for quite some time but I am not getting it. My idea is to remove certain rectangles from a list of rectangles. I have identified which rectangles to remove using a greater than equals to command and then found the indices of those rectangles. In this exmaple, 14 of those. Now once I have the lists, i connect them but it doesnt work. I have tried all the possible combinations: FLatten list with flattened list Deepened list with Deepened list

Hello All, I need to wrap a braided pattern's sweep splines onto a revolute surface. Since GGR lacks a "develop" operator, I tried using "unfold & transfer," but it results in overlapping or intersecting sweep curves. "Wrap on surface" is another option, but the helical sweeps don't have a reference surface. Is there a workaround to emboss the braided pattern onto a revolute surface? Thanks!

Dear all, I am facing an issue with the naming of the published geometries. After completing the algorithm, I publish a set of Axis points, Axis systems, lines for length, and Height for a set of facade panels. These become as inputs for the UDF that we have created to instantiate. Doubt one - Can we publish dimensions instead of lines? I couldn't find a way to do so Doubt 2 - I changed the names of my published geometrical sets but it doesn't reflect in the tree. Please see the picture below

Hi Everyone, I searched this community for information on the Loop triplet of operators and could not find information sufficient to help me with my attempt at using the operators in context of finding the greatest common factor/divisor of two numbers using the Euclidean Algorithm. My idea was to use them alongside small bits of EKL scripts hosted by Script nodes with the webapp xGenerative Design as this is what students have access to. Here is my working EKL script for the numbers 15 & 18,

In a research collaboration between Dassault Systems (CATIA), Montreal ETS (École de technologie supérieure), EstimCAD is proud to present the latest achievement in generative design for the outdoor industry. A few months ago, we started this project not knowing if we could achieve something of this level. A big thank you to CATIA, our ETS students who worked hard with the help of Dassault Systems who was always there to support us. This would not have been possible without the great work and

Hello, There is an operator that seems to be interesting but I can't find a way to make it work. Is there a documentation somewhere I could look at ? Thanks a lot ! Rémi.

Hi, Not sure if I'm asking it in the right group. But I'll give it a go. I'm more in the Mechanical/Electrical playing field. And I need to accomplish the following task. I have a cabinet which contains DIN-Rails.The DIN-rails contains drilling holes and depending on the length of the DIN-rail more or less drilling holes are appearing. I'm able with a EKL script to modify the length and accordingly more or less drilling holes appearing. But when I insert the second DIN-Rail and modify the

Morning, I've been a long time user of EKL, with PKT, BKT, now TER I now have Visual Scripting and I'm looking for some simple examples to get me started. So I figured I would create a place where we can all post simple Visual Scripting networks / graphs (I think this is an appropriate description) showing how to combine some of the functions to create simple examples. I would like to understand how to build a 3D cube of points, my image is wrong but this is my starting point. @Thomas

Hi All, I have been trying to profit from my downtime lately by investing time in learning more of the xGen functionality by building up some library assets. I have developed a workflow/algorithms with the aim to create various customizable assets of trees and bushes that can be used in architectural and civil engineering projects to generate convincing plans and elevations. The idea that I tried to stick to is to have conceptual representations for various types and sizes of plants rather
