While experimenting with the Arch_Frame command I notice two things that I'd like to discuss:
1. The selection order:
For this command the path has to be selected first. For the Draft_PathArray command it has to selected last. I find this confusing. The same reversal can be seen when comparing Arch_Remove and Part_Cut. I don't expect all workbenches to follow the same 'standard' but it would be nice if the Arch and Draft commands do.
2. Default Base Point:
The default Base Point is the "Center Of Mass" of the profile. This makes sense for symmetrical profiles. Another approach would be to assume that the user has created the profile correctly in relation to the Placement of the profile, and to use the Base of the Placement as the default. See the image.
