Hi guys, so I’m trying to split a brep into equal sections using the Perp Frames + Brep | plane functions, and for some weird reasons the outcome shows extra sections. I notice that those would appear where the curve would “overlap” (it’s sort of a C-shape curve, so the sections would appear on the along the ends). I’d really appreciate if you could let me know how to eliminate those undesired sections 
. Thank youuu!
The problem is that planes are infinite to they intersect the brep more than once. Use PlaneSrf and BBX instead.
However, the intersection at the left end of your rail/brep is not a ‘Closed Planar Curve’ like the others so doesn’t form a surface as expected. OH! That’s because my PlaneSrf is too small.
P.S. This is a bit ridiculous, getting a PxS (Plane Through Shape) of your largest section curve and orienting it to each of the perp frames.
Hi @HS_Kim, sorry for the delayed reply but I was rushing to finish the project after you gave your solution. Thanks a lot 
So, if I understand well, by using the “Closest Pt”, you’ve eliminated the sections that are not found on the planes?
Hey @Joseph_Oster, thanks a lot for your reply. I think the first solution is a better fit for what I need but I’ll keep a eye in the future where I can use your solution 
He has eliminated the unwanted plane intersections when planes intersect twice.
