Hi folks, When I change the transparency using Graphic Properties on a surface (IsClosed = true). When I set the alpha < 255 everything behaves as expected, but when I set alpha = 255 I get this funny visualization error where a few faces of the surface appear completely transparent, is this a known bug? Or is there some other cause somebody knows? Thanks, Alan

In CATIA Visual Scripting, additional "advanced operators" are available when specific roles and applications are granted and installed. These features are accessible only with named users licenses and are not available with shareable licenses. 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 :

Has anyone used the mesh isocurves operator? I am not sure what to use for "Values on Vertices" (besides passing a list of the mesh vertices) and "Iso values". The help documentation does not have much more information and I did not see anything in the wiki. Thanks!

I watched this video and I tried to imitate the operation. But I cannot find "Points to Surface" operator.(1:00) Can we use the operator or do we need use other method to create closed surface? Please help me.

OK, the title is too cryptic: Happy "St Valentin" tomorrow! in iso-surface with new function isosurfacemesh function (x**2+9*(y**2)/4+z**2-1)**3-x**2*z**3-9*y**2*(z**3)/80=0

Hi all, I'm having some issue when the input of a design sequence is an empty list. I tried to manage it with some If/Else logic based on the size of the list. Sometime the size operator gives 0, but other time it returns an empty list which cause the design sequence to fail. What would be the expected behavior and it there way workaround to address this scenario?

Hello, I have a series of points which I have turned into a polyline. The Simplify Curve operator consistently gives the error, "Points are not coplanar." I received the same error when using a series of points. The documentation indicates that this should work on 2D and 3D polylines, but this coplanarity error would insist that this is for 2D curves only, no? I'm afraid I cannot share the 3DXML, but I am curious if anyone has similar issues.

If one of the inputs is an empty list, then Append Lists also return an empty list. Is there a way to bypass this behavior?

I'm facing an issue when using the Set Attribute operator on published items. Sometime the first items does not have the attribute. It causes issue when a subsequent Design Sequence tries to read the attribute. Any idea why this is happening and how to fix it so it can be reliable? Thanks.

Hello All, I am looking for a solution to create a hard foam B-side surface for a seat, where the foam takes the shape of the cushion pan, springs, motor, and local features such as holes. I have tried using the cloth solver approach through Visual Scripting, but it takes a significant amount of time for fine geometries and does not produce the expected results. Could you please advise whether this can be efficiently achieved using Visual Scripting, or if this use case is better handled using

Hello there, dear Visual Scripting community, I am once again here to ask for your help. I am currently working on a wardrobe with multiple configurations of materials, lenght, components...I managed, with your help, to program how to make certain components disappear by chosing a material, but now I am stuck with another variable. Basically, this panel has 3 different posts (X, Y and C), with a total of 5 combinations: XXXYYYXCYC(there is no CC, for now, but I used it sometimes for balance)

Hi all, I have a use case with a customer that wants to use already existing documents in ENOVIA as inputs inside xGEN & Visual Scripting. This is not Engineering Documents, just Documents like the ones you can browse in the Document Management WebApp. When I try to "Use Existing" in the Read Data from Sheet command it seems to only show Engineering Documents in the search by default. Do you have any suggestions on how I can solve this or if it is even possible in the current release? I believe

What am I missing? csv creates an empty file in database xlsx creates nothing

Hi visual scripters, To share with you an earlier demonstration that I reworked for the Paris Packaging Week 2026 event. This demonstration illustrates how CATIA Visual Scripting can be easily combined with CATIA Live Rendering and the STELLAR visualization engine, which also uses AI-based denoiser feature (to predict pixels and speed up rendering time). This is useful for iterating very quickly and exploring many design variants with near real-time realistic rendering for glass design, all

Hi, AEC community ! Just wanted to share a work-flow employed recently in one of my projects and gather some thoughts 🙂 As an architect, I have been developing a small housing project and in this particular case have started with the ambition to use the the Natural Shape and Natural Sketch apps ( which I enjoy a lot and use often) not only for the early concept studies. But the goal was to keep the geometry created with Natural Shape as the backbone/Skeleton, driving the more detailed parts

Hello all, I have a list of lists like the example below and would like to break that list into individual lists.I tried with a loop and Get item, but it's returning the index of all lists. In my example, Get Item 1 will return -61.913mm and 0mm. I'm expecting -61.913mm, -20.638mm and 20.638. Is there any operator or sequence that could give me the expected result?

it is the modeling of pinscreen animation technique, invented in the 1930s by Alexandre Alexeieff and Claire Parker function "Visual instance" is not to be missed. it boosted the number of pin to 98000 (this picture is >40000) without big stress on the update! and from 277MB to few MB!!! of file size. Parametric animation working with raytracing makes the trick, that goes beyond the resolution (pin number)! the various shades soften the result. what I find as annoying as magical is that you

Hello All, Is it possible to group the published objects shown below in Visual script ?

Hello Visual Scripting community! I am so sorry to bother you like this on something so basic, but I am sure some of you can point me in the right direction. I am currently working on a room with modular walls. Depending on the material chosen (wood, fabric or glass), the panels that cover the walls change length, width, structure and the position of internal components. I am new to Visual Script but I know it is excellent for parametric designs like these. Is there a similar case to mine

is there any chance that the read and write sheet nodes can be made to take the document name as an input? The read/write text does (see below) i know they are functionally different but it would be extremely help if the document names did not have to be hard-coded in Visual Script.

👋 Hello CATIA lovers, The CATIA R2026x keynote replay is now available! "NOT a new update, NOT a step, a shift!" – Olivier SAPPIN, CATIA CEO This first-ever live keynote showcased how CATIA R2026x is shaping the Generative Economy. With AI, simulation, and Virtual Twin, it’s transforming the way engineering teams design, simulate, and innovate. The keynote featured insights from @Olivier SAPPIN , @Romain PERRON, and @Frédéric BOURCIER, sharing their vision and expertise on next-generation

Hi All, I'm using a Design Sequence to instantiate User Defined Features. The UDFs are used to allow users to define parameters independently on each instances of UDF. UDFs will then be used as inputs for further Design Sequences. I found out that parameters are reset each time the Design Sequence is updated. It would be nice if we can skip the update of a specific Design Sequence. Please let me know if there is way to achieve my main objective or if there is a better workflow than using UDF.

Just following up with my fun activities :) I decided to test the following "mind game" - 3D to 2D and back to AI3D generate a model in 3d using VS algorithms generate 2D data from that 3D model - (in this case - images of my palm tree models done as well in Visual Scripting ) bring back those 2D images (i3 of them more precisely ) and use AI with the help of the new functionality under the Visual Scripting App to generate a 3D model again close the circle - how crazy is that ? :)

Hi Visual Scripters, It’s been a while since our last update because we’ve been hard at work on this major new R2026x release for CATIA Visual Scripting & xGenerative Design, which brings many new features along with a complete redesign of the interface. This update will be live next week on our cloud platforms. We hope you will appreciate all these changes. As always, feel free to share your feedback so we can fine-tune or correct anything that may need adjustment. R2026x CATIA Design

Hi Visual Scripters, The service to run the new "Generative Mesh from Image" is now online for all users on our cloud platforms. This operator will generate a 3D mesh from a single or multiple images, powered by artificial intelligence and generative model. To access this new operator, make sure to enable the Beta operators option in your settings first. As this feature is still experimental, you may encounter some errors. If that happens, don’t hesitate to re-run the node computation. We

Hello Visual Scripters, I would like to export a set of xyz coordinates of points to a csv file. I found the generated file in "C:\Users\XXXXXXX\AppData\Local\Temp", but the csv is empty. Is there some other step needed to trigger the write or is there a particular format/syntax the tool is expecting at the input?

I've tried to create a UDF that includes a Design Sequence and I'm getting an error stating that some elements are Datum Features. Those elements are the published features from my design sequence. Is there a way to bypass this issue?

Hi all, Visual Scripting is definitively one of the most important innovation in CATIA. Every day we discover new use cases that can be addressed with this solution both for Creative Design and Engineering. Very often we have to compare two versions of the same part and need to quickly identify changes that might have happen on the definition of holes (can be cutouts, holes for electrical cables, fasteners...). Here just by selecting the two versions of the model (it can be isolated surfaces),

The question is How is the metalball of a set of poles with random location and random radius? How does it evolve when we free the potential? How does it evolve when we free the pole center location? This model for question 1 and 2, is by @TV . I reviewed it with current code and made a metaball User operator (new function) out of it. for the question3, I made a variation with a bounding box for the pole centers. the user operator of the metaball the center and a radius in input and then

I started to touch new function: "iso surface mesh". Here is a model about surface of equipotential between 2 points. the video is moving the points away. I have not calibrated the values to fit to any object. but if you calibrate it well, it corresponds to modelization of an equipotential of a dipole. I wish I had GGR/Xgen when I was a student... "iso surface mesh" is a world to explore in itself!

Hey all, I just wanted to check with the community before submitting SR; are there others than me facing issues with both VS and xGen after the 2026x update? I was able to run both on monday, but yesterday and today I'm getting stuck at the following screens when creating new parts with design sequences:

Hi fellow xGen users! I have been developing some more conceptual assets to be used directly in architectural assemblies and generate 2D plans and elevations when needed. Representing greenery along with other assets in city planning and various other digital twin applications is essential and I have been putting some effort in my spare time to develop such capabilities. CATIA Visual Scripting is an ideal application for such exercise due to its versatility and capability to employ established

In the CRE What’s New information, it looked like we were supposed to be getting more advanced operators with XGG, but after the update none have come through. What happened?

26x just arrived. I wanted to make a retry on basic L sytsem before new functions. better understanding / better skills / much much better Visual Scripting!!! BEFORE (2021) AFTER (2025) 7 iterations -> 4373 points, 26s (which is good for me) the logic is the same as 2021, 7 iterations

Helllo, I have the following question: I would like to use a Power Copy that contains a Design Sequence. Is there a way for a user to use this Power Copy without having the “Visual Script Designer” role? Similar to how UDFs (User Defined Features) can be used via the “Quality Rules Reuse (CATKE1_AP)” app. Or is there a general approach that allows users without the required role to use predefined Design Sequences.

Following this post Basically the logic is the same as previous post. what is different compared to the post for kites and darts? the substitution rules that I used expand the surface of the pattern (Cf 3DStory at the bottom). so, the rhombs overlap. I added a logic to get rid of duplicate rhombs within the loop. I started to use a lot the function indicated by the arrow above. You can sort on a given item which makes sense for you or easy to calculate for CATIA. Then, you can structure

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!

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.

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
