Thinking about doing a LDCad 1.7 version

[N. W. Perry]

This would need additional information stored in parts (like snapping and mirroring).
Afterwards it would need a way to cycle trough the orientations that information supplies.
Someone has suggested something similar like this before in order to use something other then the parts local 0,0,0 while dragging/snapping.

Some parts have this info included in HELP metas—perhaps there's a way to search these metas for possible suggested rotation angles?

For other parts, Selection Info could help figure these angles, if it were possible to select (or snap to) part vertices.
