-## unionRoundMask
-### Union with round fillet at selected places.
+## unionRoundMask / unionRound  
+---
+### Union with round fillet at selected places. Created for Round-Anything by TLC123 (2021).  
+A shortcut for faster fillet union is enabled when the operation constrained to convex operands.  
+For most cases unionRoundMask / unionRound replaces MinkowskiRound.  
+Combined with a system of mask selectors, unionRound becomes even more versetile.

 Module unionRound is the underlying work module of unionRoundMask. 
 It can be used by it self, in some cases faster but more raw.
