Unfolding projection :

Use the following dialog box in order to modify the unfold projection parameters :

If the " Project to machine " option is ticked, this means that the unfolded will appear in the origin plane (z=0). This is indispensable to be allowed to use the unfolded in a TopPunch document. If this option is not ticked, the user will be able to position the unfolded where he wants or let it in place according to the reference face.

The " Upper view of the reference face " option allows you to force the unfolded (in top view in relation to its reference frame) to be in the same direction that when we look it along the unfolding reference face top view. This option is useful when a machining side must be respected (because of the deformations or constraints due to the matter).

It is possible to give a scale factor to the unfolded.
