Visualizing Broken Constraints between 2D and Generated Elements

You can visualize broken constraints, following the modification or deletion of generated geometry.

Broken constraints can be of the following types: parallelism, perpendicular, coincidence, concentric, tangency and symmetry.

Before you begin: Open a 2D shape and open or create the associated drawing representation. Make sure that:
  • The Show Constraints icon is active in the Tools toolbar,
  • Or the Display constraints check box is selected from Tools > Options > Mechanical > Drafting > Geometry tab, Constraints Display area.
In the drawing, add some 2D geometry in the drawing and create constraints between this 2D geometry and generated elements.

About Constraints

  1. Modify the 2D shape in such a way that some constrained generated geometry will be modified or deleted.

  2. Click Update in the Update toolbar.

    Broken constraints are represented by a red warning-like symbol . Valid constraints are also displayed.

    Notes:

    • When deleting a use-edge, the constraint created with it is broken.
    • When multi-selecting the geometry and its constraints for copy-paste operations, broken constraints are kept and pasted too. If the entire geometry is not selected, constraints are not copied.
    • The color used to visualize broken constraints is the color defined for inconsistent elements in Tools > Options > Mechanical > Drafting > Geometry tab, Colors area, Visualization of diagnostic.
    • The size used as a reference to display broken constraints is the same as the reference size defined for constraints (2mm by default) in Tools > Options > Mechanical > Drafting > Geometry tab, Constraints Display area, Reference size.

  3. To find out the original type of a broken constraint, move the mouse over the broken constraint symbol.

    The associated tooltip is displayed.

  4. To delete a broken constraint, select it and use the Delete contextual option or press the Del key.

    The broken constraint is deleted.

  5. You can also try to delete some geometry.

    The associated constraint is also deleted.

You have now learned how to visualize broken constraints.
