HI,
Usually an arc consists of 3 points. Start, Center and End point. But from your picture it seems like that there is more than 3 points. can you clarify more regarding your problem?

Hi,

An arc is a curve class derived, so you can get points on the arc with something like this:

dim sp,ep as double
dim dp as double= 0.1 '<--Set this var to any value in order to obtain dense or sparse points
dim ds as double
dim pcoll as new pointcollection3d

sp=MyArc.StartParam
ep=MyArc.EndParam
ds=sp

Do While ds <= ep
 pcoll.add(Myarc.GetPointAtParam(ds)
 ds=ds+dp
Loop

Additionally, you could use GetPointAtDist(double distance) - depending on your exact needs.
