There is something wrong in the intersectwith function, how to deal with this?

Almost can't imagine it but, but don't see any other expanation:

Explain this:

Point3dCollection snijpunten = new Point3dCollection(); bovenaanzicht.IntersectWith(hulplijn1, Intersect.OnBothOperands, snijpunten, IntPtr.Zero, IntPtr.Zero); int aantalsnijpunten = snijpunten.Count; if (aantalsnijpunten > 0) { foreach (Point3d snijpunt in snijpunten) { double debug = bovenaanzicht.GetDistAtPoint(snijpunt);

I get a 'eInvalidInput' at defining the 'debug double'.

I'm calculating pretty much intersections in my code and suddenly this happens, every time at same moment.

Was having a similar issue a few days ago, couldn't figure it out, so rewrote the whole code in some other way, now this same thing happens again...

Is there a way to solve this?

Hi,

This is perhaps an accuracy issue (this may happen if entities are far away from Origin).

You can try this:

Point3d pointOnCurve = bovenaanzicht.GetClosestpointTo(snijpunt); double delta = snijpunt.GetDistanceTo(pointOnCurve); double debug = bovenaanzicht.GetDistAtPoint(pointOnCurve);
