I’d like to boolean two sets of complex curves. All curves are closed, disjoint, non selfintersecting, and coplanar. But there can be dozens of them. Is there a fast and automatic way to do this outside of grasshopper?
So far I’ve:
 developed a workaround using extrusions and solid boolean operations, but haven’t turned it into a script yet.
 I’ve found Clipper’s
BooleanPolyline
function  this showcases the functionality I’d like to have, but lacks full nurbs curve support.
Current Practice
For boolean union I can use _curveboolean _pause _allregions
.
For boolean difference I do:
 Use
_ExtrudeCrv _Solid=yes
with distance 1 for set A, and 0.5 for set B. Creates two sets A’ and B’ of solids.*  Use
_BooleanDifference
to create a set of solids C’ = A’  B’.  Create plane P in the construction plane, containing the projection o C’

_Intersect
P and C’. Gives result C = A  B.
Intersection is similar.
I think the intermediate shape is rather fun! However I’d like to make the technique less manual. This message is to check if it’s already done. Thanks!
*) I use a 0.5 extrusion height for B’ in order to avoid the boolean difference failed
error, which happens if any solid in B’ fully contains some solid in A’.
