Description
A check for overlapping contours is now available, when unfolding a sheet metal design using Unfold 2D. This check generates a warning and highlights overlapping or touching contours in a preview.
 | If the Both Sides checkbox is selected, the evaluation is done based on the base surface only. |
In addition to Unfold 2D, the check is also available for Multi Unfold, Create Flat, and related dependent view creation and update tools in Annotation.
• In Multi Unfold, the overlapping contours are visible when you select the Preview checkbox.
• In Annotation, a message is generated if overlapping contours are detected. Simultaneously, a table opens, listing all flat views with overlapping contours. You can also open the table by clicking > in the Setup group.

The following sheet metal macros are added to control the behavior:
• sha_show_flat_sheet_contour_overlap_result
◦ :DISPLAY, :NO-DISPLAY, :RET-VALUE
• sha-inq-last-flat-contour-overlaps-outcome
Benefits
Design validations to help avoid costly manufacturing issues downstream.
