Hi @morja​,

You can use the FME Hub transformer TransformationMatrixExtractor to extract the transformation matrix parameters from the IFCDoors, then use the 3DAffiner transformer to apply those parameters to the DWG blocks. Your DWG blocks should be at 0,0,0 before applying the affine, since the it will also move the block into the correct location.

Hej @daveatsafe​ ,

Thanks a lot for this hint. I have tried several different approaches and came up with this:

The "A"-value in the transformationMatrix seems to carry the cosine-value of the geometry's rotation.

I do use it directly (after converting it into degrees) to assign it to the wgStyler-Transformer for the "Rotation"-input. so far it seems to work quite fine.

Would this be an appropriate way of dealing with the problem?

best,

Morten

The A value is cos of the rotation angle * scale, but I think that for IFC, the scale will usually be 1, so your shortcut should work.
