How to set leader attachment position to surface

[KB_9753804]

Hello everyone,

I create leader note , for that I passed surface selection with view and pointed , but still It goes outside the view , please help me to resolve the issue.

I shared the code for your reference.

I’m not at my desk, but I guess you need to transform your point to screen coordinates. This implements a user action in a drawing, where the user picks the location in the drawing. This is not the same.

Dear sir, 

I transform the point to screen coordinate but still it goes outside the boundary ,I share the code for your reference.

You have two options:

1. Create in Creo a point and extract the placement xy points
2. Create with Toolkit a point 

For both check the difference, I guess it's a transformation issue.

ProDrawingViewTransformGet (

...

ProBoolean view_to_drawing

..)

For me this should be TRUE (You have true) because you want the transform from the Model View to Drawing Coords.

Did you validate the given Drawing View?

If you use 1.0 hard coded for the edge, are you sure this is valid and possible (I knew 0.0 - 1.0, but ...) ?

Same here first figure out how to create just a point within the drawing at the requested position. You can measure this in your model and use this in your code for testing. 

Is noteLocation correct?

ProDtlattachAlloc(

...

location - The attachment location. Use if
the attachment type is set to PRO_DTLATTACHTYPE_FREE
or PRO_DTLATTACHTYPE_OFFSET.
For drawing objects and symbols and surface finish on
flat-to-screen annotation planes, this should be in
screen coordinates. For symbols and surface finish on
3D model annotation planes, this should be in model
coordinates.

...)

Most likely the same problem as in:

Solved: Creo ProToolkit API pfcSelection::SetPoint() is no... - PTC Community

when working with surfaces or edges there should be ProSelectionUvParametSet() call.

Thank you , after setting the UV parameter , Leader positioned at correct location
