Problem with GeneralDimensions.AddLinear an SketchLine3D

[ASchroeder]

The DrawingView show an Construction with a occurence, which hold an 3DSketch with 3DSketchLines. This 3DSketchLines are the Elements, which are identified by startPoint and endPoint. This Lines are the geometrical objects which i have to dimension. The sketch with this Lines would be included as Sketch3DProxy in oBaseView (and all SketchLine3D as SketchLine3DProxy too, but I'm not shure if have to do this).

The Script found the correct Lines, the Sketch are included, the GeometryIntent are created but the GeneralDimensions.AddLinear-function are failed. I have tried various methods to create the Intent, but nothing changed. Every call failed.

Anyone who know a solution for this problem?

Thanks

PS: startPoint and endPoint are own Objects with X,Y and Z Values in mm

Nobody, who know what to do? Or is it impossible?
