Change Annotation View Direction automatically

Hi, @zynkana

When you are trying to execute ProDimensionPlaneSet(), your code could have returned PRO_TK_NOT_VALID. That means the ProAnnotationPlane supplied to ProDimensionPlaneSet() is not frozen.

This is kind of native Creo configuration. Even when you are trying to modify plane reference for a dimension, we can't uncheck Freeze annotation plane reference in the Edit Annotation Plane dialog as in the below snap.

So before supply the ProAnnotationPlane, freeze it using ProAnnotationplaneFrozenSet() (refer Sample Code).

Sample code:

ProAnnotationPlane cPlane;
status = ProAnnotationplaneFrozenSet(&bPlane, PRO_B_TRUE, &cPlane);
status = ProDimensionPlaneSet((ProDimension*)&pAnnotation, &cPlane);

// where,
// bPlane - deduced annotation plane
// cPlane - annotation plane frozen
// pAnnotation - annotation reference

// *Above code is tested for Creo Parametric 9.0.5.0.

Happy coding!!!
