用来反转面，反转法线，反转线条首尾。Flip normals of polygons or objects Flip (Reverse) splines

this scripts does the same thing as a free plugin GLUE does, namely it glues objects to a surface. i've written this sript because i was tired of necessity of looking for new recompiled plugins with every new max release. and this script can do a bit more than original: it can align glued objects to normal, and you can glue along any vector, defined with tape helper object. more with newer version - vertex projection, eye ray, more precision.
