Whilst working out the non-right-angled cylinder intersection sub-parts for the
Boat Rigging pieces I have run into two related problems
1) I have a triangle A-B-C that is so tiny that L3P reports it as co-linear and
L3Lab doesn't render it (it looks OK in MLCad though)
2) I have a large quad C-B-D-E that L3P reports B-C-E as co-linear and L3Lab
doesn't render (but again looks OK in MLCad)
Now the triangle and the quad share the very short edge B-C but are not
co-planar so I can't replace them by any larger combinations. Also, omitting
A-B-C and making the quad into a tri leaves obvious gaps as the sub-part is
scaled when it is used.
Should I
a) ignore these "errors" as they arn't really errors and assume that other
renders will render them OK (like MLCad does)
b) pre-scale the sub-part (which seems counter-intuitative as it then doesn't
follow the pattern of the right-angled cylinder intersection sub-parts)
Thoughts?

| (...) I'm guessing this is a limitation of the accuracy of the l3p -check, so probably ignorable. Does the -dist option affect this test too, or just the coplanar quad test? Maybe there could be another option in l3p to adjust the accuracy of the (...) (20 years ago, 8-Jan-05, to lugnet.cad.dev)
