Using findBRepByUsingPoint

[pludikar]

Hi,

I'm trying to use the findBRepByUsingPoint method found in component:

if I have a face entity:

face.assemblyContext.component.findBRepByUsingPoint(face.pointOnFace, adsk.fusion.BRepEntityTypes.BRepFaceEntityType)  >>  returns an objectCollection

but 

face.assemblyContext.component.findBRepByUsingPoint(face.pointOnFace, adsk.fusion.BRepEntityTypes.BRepFaceEntityType).count returns 0 - meaning it hasn't found anything.

I would have expected it to return count of 1.

Am I missing something?

I think pressing the send button, is cathartic, makes me relax and when I'm relaxed I come up with solutions.

The issue is, and this seems to be the way F360 works, is when working and modifying Occurrences, you MUST be working with the NativeObject.  I had assumed that you had to be working with the Occurrence and, because everything is in same world coordinate space, and the occurrences would take care of the rest - Not so!!

face.assemblyContext.component.findBRepByUsingPoint(face.pointOnFace, adsk.fusion.BRepEntityTypes.BRepFaceEntityType)  >>  returns an objectCollection

face.assemblyContext.component.findBRepByUsingPoint(face.pointOnFace, adsk.fusion.BRepEntityTypes.BRepFaceEntityType).count returns 0

The component referred to by: 

face.assemblyContext.component

 is actually in the nativeObject space.  So 

face.pointOnFace

the resulting coordinates are in the wrong place

The solution:

face.nativeObject.pointOnFace

and now

face.assemblyContext.component.findBRepByUsingPoint(face.nativeObject.pointOnFace, adsk.fusion.BRepEntityTypes.BRepFaceEntityType).count >> returns 1

Hope that helps anyone else who has come across the same issue
