I created several curves by coding,but when I use _planarsrf to create surface,I can’t work.
I know they should be closed planar curves,and I checked they were closed curve,my question are :
1.How to know they were planar curve? if they were not ,how to make them planar.
2.I have tested to project them onto a plane almost ‘paralled’ to the curve,but the _planarsrf still could’t to work. why?
