convert circle and ellipse to a polyline
hi all!
is there a quick and easy way to convert a circle object or ellipse object to a polyline object?
prefferably i want to create a polyline with small straight lines.
regards mikael

for oddbellipse the simplest and quickest way is to use oddbellipse::explodegeometry().
for oddbcircle, i'm afraid, there is no such simple and quick way.

what about converting the oddbcircle to an oddbellipse (i.e. defining an oddbellipse that is circular) and then using explodegeometry on the resulting oddbellipse?

not very simple and quick way
sincerely yours,

i would recommend to use oggecirculararc3d and odgeellipticarc3d classes and their methods getsamplepoints(). they are intended to solve exactly yout task.
using oddbellipse::explodegeometry() is not safe - it may return oddbcircle for example at some point.

ok. that sounds great. there might be a solution to my problem after all
i'am reading autocad files to transform the objects to antoher coordinate system.
how do i convert a oddbellipse object to a odgeelliparc3d or a odgeelliparc2d? i there perhaps a code sample of this somewhere?
anyone tried this? is it possible?
