+module unionRoundMask(r=1, detail = 5 , q=70, epsilon = 1e-6, showMask = true) 
+
+Masks are a method to perform unionRound on selected only areas 
+and circumvents the limitation of common convex work area
+Mask are just common primitives that is used to mark out areas.
+
+usage:
+unionRoundMask(r=1,detail=3,q=30)
+{
+    yourObject1();
+    yourObject2();
+        yourMask1();
+        yourMask2();
+        yourMask3();
+    //    ...
+    //    ...
+    //    ...
+}
+
+#unionRound
+module unionRound(r=1, detail = 5 , q=70,  epsilon = 1e-6)
+
+Module unionRound is the underlying work module of unionRoundMask. 
+It can be used by it self, in some cases faster but more raw.
+
+usage:
+unionRoundMask(r=1,detail=3,q=30)
+{
+    yourObject1();
+    yourObject2();
+}
+
+
+#intersectionRound
+module intersectionRound(r, q=70,  epsilon = 1e-6,showOperands = true) {
+Undocumented for now.
+
+//helpers
+module  clad(r,q=70) // speed is limited to convex operand
+module shell(r,q=70) // not in use
+module inset(r,q=20) // speed is limited to convex operand
