geometry data for circles and lines with non-zero thickness
geometry data for circles and lines with non-zero thickness
hi,
since circles and lines can have non-zero thickness and they can rotate along any directions, it seems to be a non-trivial task to get the geometry data for these entities. for circles with non-zero thickness (like a hollow cylinder), is it possible to retrieve data as a list of faces that would compose the circle? for lines with non-zero thickness, which actually looks like a face, how should i get the 4 points that make up the face?
thanks,
-kyu

you should use dd vectorization engine, see odvectorizeex sample
sincerely yours,
