so in Blender we have edge/vertex slide which does moving edge/vertex constraints to nearest edge or nearest vertex. but as far as i know, we don't have Face and Normal based constraint. How achieve this kind of constraint in Blender?
Please take a look at this video at 22:58
-As for face constraint, i found complicated workaround which uses shrinkwrap modifier, then duplicate the object and make it as target, which is not the best solution.
thank you guys!
