@llaves yes, dimensioning radii in LayOut needs to be added. I'm keeping my fingers crossed. Currently I just use a label for that in LayOut. It works well enough. You could put in temporary radius/diameter dimensions in SketchUp and give them a tag which you can turn off in LayOut once you placed the labels.

Doing this also makes it easier to maintain consistency in the appearance of dimensions in LayOut. It's a pain at best to combine dimensions and leader text from SketchUp with dimensions and labels in LayOut.
