Hallo,

I need to convert the coordiante of the sketch point to assembly coordiante.

I tried this macro to convert but the result in wrong, the correct result are the coordiante in the lower of frame of SolidWorks (see the image)

The part in the assembly is traslate in X axis of 100 mm about, so the assembly origin and the part origin insn't the same.

The macro return the point coordinate reference to the part(model) not the conversion of the assembly coordinate.

have you any idea how to fix it?

Thanks a lot

Roberto

' Preconditions:

'       (1) Part, assembly or drawing is open.

'       (2) If a part or assembly, then a sketch is being edited.

'       (3) If a part or assembly, then an entity is selected in

'           the sketch.

'       (4) If a drawing, then an entity is selected.

'

' Postconditions: None

'

' NOTES:

'       (1) If the sketch is a 3D sketch, then the selected sketch

'           point is automatically in model coordinates.

'       (2) If the sketch is a 3D sketch, then its transform is the

'           unit transform.

Result in the immediate window
