Datum on a Spline, Automation Error Help
Datum on a Spline, Automation Error Help
(OP)
I am writing a program which will go into an assembly part, and place a Datum on a spline, which will be brought in with one of the assembly components.
I am manually selecting the spline, and I am having the following error:
NXOpen.NXException:Internal error: memory access violation
at NXOpen.Section.AddToSection(SelectionIntentRule[] rules, NXObject seed, NXObject startConnector, NXObject endConnector, Point3d helpPoint, Mode featureMOde, Boolean chainWithinFeature)
at select_a_spline.Main()
The code is as follows
I think the problem is with the section2.AddToSection, but I've been fighting it for several days and have not been able to resolve the issue.
Any help would be greatly appreciated.
