Highlight is delivered to enable the automatic creation of detected geometrical constraints when:
· Creating a geometry by snapping to external geometry (background element).
· Dragging and snapping an existing geometry to other internal/external geometry.
Requirement origin
Earlier in both of these cases of dragging and snapping to internal and external geometry it was assumed that the constraint was created. However, once the user is finished dragging, they will discover that the constraint was not actually created between the snapped elements it was only displayed in preview to place the geometry correctly.
User needs to apply the manual constraint to individual item.
What is offered & how it serves
Background or external element: Background or external elements are considered as all 3D elements not belonging to sketch, visible in the sketch’s view. This includes bodies, faces, edges, and vertex.
The snapping to external elements depends on Sketcher preferences and visualization filters: “Detects the geometrical constraint on background elements” checkbox must be set to ON in Sketcher preferences, and the visualization filters must authorize the visibility and the selection of background elements.
Upto 3DEXPERIENCE R2018x GA, in the sketch, when creating a geometry using the Smartpick by snapping to an internal geometry, the detected geometric constraints are automatically created if the “Creates the geometrical constraints” option is enabled, it was not possible to create constraint when dragging a geometry on another geometry, or snapping to a background element.
Through this function, if the “Creates the geometrical constraint” option is enabled, the detected constraint by the Smartpick is automatically created on the internal or external geometry regardless the mode used.
- When geometry is created by dragging:
- When geometry is created on external element:
To allow the automatic creation of constraints detected by the Smartpick in better conditions, a new option is added to Sketcher preferences in order to choice the snap mode of Smartpick.
The user is able to choice between the detection of “all visible elements” or the “last flown over element.”
If the “last flown over element” snap mode is selected, detection of constraints will occur only on the last flown geometry. The user should fly over another element with the mouse to detect a possible constraint with this element.
In the “All visible elements” option all geometries in the sketch scene are taken into account for the detection of Smartpick.
By default, “All visible elements” option is “On”, and “Background Elements “option is “Off”.
