Hi,

Do you know how to find by scripting the bounding box of a body, along a specific direction that is not aligned with the origin ?

Hello GUICAD

I'm not very clear with your query.
Do you wish to use scripting to align the bounding box of the component in a specific direction?

Hello  Subashni

Yes exactly.

Hello GUICAD

I found the below script and it may help you get the projected points using a bounding box.

body=GetRootPart().Bodies[0]
boundingBox=body.Shape.GetBoundingBox(Matrix.Identity)
center=boundingBox.Center
view=ViewHelper.GetCurrentProjection()
viewZDir=Direction.Create(view.Item[2,0],view.Item[2,1],view.Item[2,2])
newFrame=Frame.Create(center,viewZDir)
centerPlane=Plane.Create(newFrame)

for p in boundingBox.Corners:
    pProj=centerPlane.ProjectPoint(p)
    SketchPoint.Create(pProj.Point)

# Create Box
result = BlockBody.Create(Point.Create(MM(-10), MM(-10), MM(0)), Point.Create(MM(10), MM(10), MM(20)), ExtrudeType.ForceAdd, Info1)
# EndBlock

 

Please let me know if this helps. As I'm not very well versed with scripting I may need to consult the experts on this and get back to you.

Hello Subashni

Thanks for this information, but it's not exactly what I'm looking for.
The goal is to get the maximum dimensions of a part that is not necessarily oriented correctly with respect to the world origin. (the creation of the box is not desired, just get the maximum dimensions)

With "boundingBox=body.Shape.GetBoundingBox(Matrix.Identity)" i get the bounding box oriented with respect to the world origin while I would like to orient this box with respect to a local origin (with as direction Z, the direction of the edge of maximum length

Hello GUICAD

Ok I understand now. 

Let me check with my team if this can be done.

Hello GUICAD

I discussed with my team and I gather that the Bounding box per definition is aligned to the coordinate axis. So I believe that cannot be changed.

An alternative workaround would be to use the 'Create workpiece' option.
