Thanks to mac1 and EarthMover for the replies. I read the link Earthmover posted and it concludes Sketchup is not the best CAD to use when making complex fillets. Sketchup is very intuitive though which helps with the creative process, so hopefully new developments are on the way.

From your pic it does not look like you have formed an edge between the two objects to have a ref for follow me to follow. Intersect them to get edge ref??

here are pictures showing the intersection line with both shapes and one shape.

Hello,

Thanks to Mike Lucey for referring me here. I am creating a water fountain and have to run a fillet along two intersecting shapes. the shapes are composed of segments of 3D quarter sections, and I couldn't get the Round Corner by LibFredo6 to do it. Any suggestions? I have attached a picture of the two shapes.

Any direction would be greatly appreciated
