Trim Radius changes arc into spline
Trim Radius changes arc into spline

Hi,
trim curves between 2 circles changes one part of the arc into a spline.
I hope the uploaded file can be viewed, it is the red curve, converted from an arc to a spline. I tried different things with different curves and it seems odd, but it is always the left portion of the arc which is converted.
Does anyone have the same problem, and how do you work around the issue?
Thanks a lot in advance.

I will experiment and hopefully get back to you if I see the same behavior on my end.

I think I figured it out. This only happens when the center point of the circle is located on a CSYS origin point. If the circle is created about a regular point or an arbitrary location it does not occur. I tried several configurations and every time the circle is centered on a CSYS it turns into a spline when you trim it.
My only conclusion is that this is a bug in the NX coding. Siemens should be notified if this is not intentional.
