Why is there a difference between Trim and SDiff?

[Gijs (Gijs de Zwart)]

Same behavior as in native Rhino, both ik result as in speed. But you might try the python version:

Boolean difference in gh much slower than in Rhino

The same using python / Rhino common takes 1.1 seconds (using the brep lists variant of Boolean difference) So my guess is that the current SolidDifference tool in gh uses the first implementation of BooleanDifference. Could well be the same with SolidDifference, I haven’t checked yet So this solution is actually much faster than the built in solid difference. the one that took 43 seconds takes 2.8 seconds now for substracting 24 objects from the original solid. But still it is slower than Rhin…
