detect model with only 2d entities
hello,
is there a mechanism to find out if a model has only 2d entities in it?
thank you

there is no "direct" way. the simplest way is, probably, to calculate extents of model space and compare difference in some coordinate with zero. but this is inefficient way, and it won't detect 2d models that are not in plane, collinear with one of xy, yz, xz planes. the correct way is to iterate through the entities and to check if they all are coplanar.
sincerely yours,
george udov
