the macro is intended to unroll lofted faces, function beyond that is (in current version) a bonus

settings are not context aware, all settings not applicable are ignored. as example, using autoscaling ignores the scale-value in the form

v1.1  (2022-07-24) py3/qt5 compat, cosmetic code changes, minor code tweaks, used gridlayout for form, added option to skip drawing, made new layout engine with techdraw, the drawing wb layout engine is now called "legacy" v1.0.1 (2019-02-01) - on git v1.0  (2013-09-14) - on wiki

note: - unfolding sometimes works and sometimes not - not all surfaces are theoretically possible to unroll
