Five volumes 41 40 39 23 38 with no par surface points¶

checking the csg type mask of offenders, using current default parsurf_level=2¶

using adaptive parsurf_level to meet parsurf_target number of surface points, pushes the five volumes down the chart ...
- reaching level that suggests just a problem with parametric sampling of surface points for intersects between sub-objects of very different scale rather than with the actual CSG geometry

bumping up parsurf_level to 4 increases nsp (numSurfPoints) by factor of 10 for most, but “intersection difference cylinder cone” still far too low
- also unusably slow to increase this drastically for all

All five are similar structure: (co-co)cy

issue appears to be due to the cones being huge compared to the cylinder, so the cone surface points are insufficient in the small region of the intersected cylinder

Vizing the primitives, note very large flat cones with the cylinder poking thru it:
