Used when finding subelements of a feature. Many of the comparisons used to also
check for string lengths, but as far as I can tell they are not strictly
necessary (see https://www.cplusplus.com/reference/string/string/substr/) and
just `substr` can be used without them. However, `compare` explicitly is for
comparing, and does not make a new object that `substr` does.
Similar to PR #5170 for loft. This commit squashes the following commits.
[PD] Refactor `Pipe::execute` and support point sections
[PD] Allow point profile in selection-based pipe workflow
[PD] Only add sketch subs if it is vertex
[PD] Make both end faces of pipe regardless of point sections
Earlier we were checking if these faces correspond to point sections, but
apparently the end faces are independent of the order in which the sections are
added, so the "front" may be the face closest to the last added section, rather
than the "profile". Creating null faces and adding them for sewing together into
a solid does not appear to have side-effects so far.
With these changes, one face per solid can be added as either the first
"profile" or subsequent sections in loft and pipe.
This commit depends on `App::PropertyXLinkSubList` preserving the order in which
sections are added.
A minor change this also adds is that when a solid's face is selected that face
is mentioned in the fields instead of the solid (eg `Box:Face1` instead of
`Box`).
- Previously a subtractive pipe on a body with no solids would create a solid. Now Pipe will generate an error.
- Fix incorrect property header. Previously Pipe was identifying itself as Pad (copy paste error)
-Rename Sketchbased to ProfileBased to show new behavior
-Adopt ProfileBased to make the relevant helper functions work with faces too
-Adopt features for unified use of helper functions
-Adopt commands to allow face selection
They worked and are nice feature, but the handling with properties must be worked out better. To avoid any incompatibility due to property changes the functionality is removed now.
