Offset planar curve maximum number of control points?

Does the Offset Curve component have a maximum number of control points it can handle? My curve has 6812 control points and the offset fails after a certain percentage. I can flip the curve and the problem occurs on the other end of the curve.

Attach your file please!

This won’t be possible. It’s much rather a question to the developers whether the command has an actual maximum number of points it is capable of processing.

Hey Martin,

I think it is not about the nº of control points but about the curve itself. I have done an intersection between a mesh and a plane, getting a sagged curve like yours and then test it.
Here the results:

I attached a simplified example. Why does the offset fail on this curve?

Please note, I’m working with an interpolated curve, not a polyline.

it definitely looks like there might be a cap somewhere

Could this be a hardware cap?

Well Jordi, you changed the input values. And it seems you might have different tolerance settings. Or for some reason your offset curve has 20’000 something control points while mine has 37117 control points.

Below is my system info:

I don’t think this has to do with hardware specs.
