Edge co-ordinate in drawing view

  • July 8, 2016

Hello,

I have edge handler selected by user from ProSelect API. This selected edge is in drawing view. I would like to know edge coordinates in terms of drawing sheet origin using pro toolkit.

What XYZ co-ordinate I will get if I will use API something like EdgeXYZEval? Will it be of assembly co-ordinate? If yes, how one can convert it to screen co-ordinate of drawing file?

Let me know if you need more clarification.

Any thought will be of great help on this.

Thanks and Regards

Ketan

Hi all,

Ketan please take a look at the code corrections.

ProAsmcomppath error is due to a part selection , the correct technique is to check for a NULL as an owner of ProAsmcomppath and reinit if this was the case or simply initialize matrix to identity matrix - the results would be the same.

I was not correct suggesting inverting matrix - this suggestion was related to drawing sheet matrix when you'll need to go from 'paper coordinates' to drawing coordinates - not needed in your case.

HIH.

Feliks.

Hello all,

Ketan, here is a workflow:

- from the edge's ProSelection get ProAsmcomppath, ProDrawing and ProView

- get Point3d from ProSelection

- get assembly component path transformation from part to assembly

- get transformation from assembly to drawing view ( don't forget to invert )

- get transformation from drawing view to drawing sheet ( this one is optional)

- multiply transformation matrixes to get the total transformation

- transfer Point3d using the final matrix to view ( drawing) coordinates

HIH.

Feliks.

    Thanks Feliks for this information.

    Could you please help me from below step no 3 as I could reach till that point and could not find how to proceed further:

    1. from the edge's ProSelection get ProAsmcomppath [ProSelectionAsmcomppathGet], ProDrawing [ProSelectionDrawingGet] and Proview[ProSelectionViewGet]

    2. get Point3d from ProSelection [ProSelectionPoint3dGet]

    3. get assembly component path transformation from part to assembly

    4. get transformation from assembly to drawing view ( don't forget to invert )

    5. get transformation from drawing view to drawing sheet ( this one is optional)

    6. multiply transformation matrixes to get the total transformation

    7. transfer Point3d using the final matrix to view ( drawing) coordinates

    To conclude, I got 3D point of selection and transformation matrix of 3d point with respect to assembly. Now, I am not sure how to proceed.

    Thanks and Regards

    I use this method <ProDrawingViewTransformGet>,Translate the (0,0,0)point from the 3D model to 2D drawing origin.
