Construct Unfolding of Faces Set

To create such a profile, expandable faces are selected. Such faces should have common edges.

After selecting the source faces and the point that determines the position of the profile, "inseparable" edges are specified, if necessary. To do this, you need to activate the Cut by edges flag in the properties window, and select the “inseparable” edges using the auto-menu option:

The selected edges will be added to the corresponding list in the properties window. To edit the list of inseparable edges, use the buttons Collapse , Delete element from the list , Clear .

The Delete redundant edges flag allows you to delete the edges of the source set on the 3D profile file.

If there is at least one non-unfolded surface in the list of unfolded faces, the system uses an iterative algorithm for constructing an unfolding. In this case, it is necessary to check that the unfolded faces do not form a closed contour, because it is impossible to specify a cut along the edges.
