Hi,

I am currently trying to construct an object from a plugin, having a list of points and vertices etc. I found the Modeling class in the SDK but I am guessing there must be a much simpler way to create a polygon object (points, vertices, faces) from C++?

Sorry if this seems trivial...I couldn't find anything on this topic

Thanks

Markus

Hi,

if you want to do it by hand you have to alloc your poly object, then get the points and poly arrays, and fill them by hand.

somewhat like this:

maybe there's a better way to do this, but this works for me
