I have a roof with a steel rafter, and a wood Valley beam. I need to do the following:

1. Detail a steel support saddle for the valley beam that is welded to the web of the Steel Rafter with minimal interference with the flanges.

2. Trim the wood beam parallel to the steel rafter and bottom plate of the saddle.

As you can see I started the side plate and bottom plate for the saddle using reference planes.

Can I mirror one side plate to the other side? I couldn't figure out how. The plate is locked to the face of the valley beam.

Also, coping the wood beam creates an ugly, completely unrealistic cut. It should just be one straight cut.

FROM THE FILE YOU ATTACHED YOUR SADDLE IS RUNNING THRU YOUR MEMBER AND SEEMS HIGH ON THE STEEL MEMBER. IAM NOT SURE WHAT YOU ARE TRYING TO ACCOMPLISH WITH THIS.

FOR THE COPING ISSUE I WOULD CREATE A REFERENCE PLANE WITH THE CUT YOU WANT AND CUT THE ELEMENT TO THE REFERENCE PLANE. IF YOU NEED A MORE COMPLEX CUT YOU MAY HAVE TO USE MULTIPLE REFERENCE PLANES. I DEMONSTRATED THIS IN THE ATTACHED MODIFIED FILE.

I cut the beam with reference plane as you suggested.

I created the steel saddle with a work plane on each side of the valley rafter. Then moved it flush to the top of horizontal steel beam, then up 8" as a guess. I made a void extrusion to cut the saddle components flush to the face of steel rafter web. Is that the only way? I didn't get the option to Cut Geometry with a Reference Plane like I do with beams.

But now there's a little piece of the saddle sticking through the rafter flange. So I want to move the saddle down 1", but I can't move it vertically anymore. I made another void extrustion to cut the nub off the side plate, but I still don't know why I can't move the whole saddle vertical now.
