Creating bodies from existing geometry

[hacketet]

I am currently using Rhino V7 so I come from a VERY different environment. I designed my current house 40 years ago in AutoCAD v1.0 and then migrated to Ashlar Vellum 3D before starting to use Rhino3D v4. I'm preparing a series of instruction videos for modelers who want to use 3D printing, but can't figure out how to use CAD programs. It is understandable that they would not want to spend $1000+ for a program they may not be able to use, so I am focusing on the programs that are free and have reasonable capability - OnShape, Fusion 360, and FreeCAD. FreeCAD is particularly interesting because the user has complete control of their files and I understand that some of the viewers will be small mom and pop manufacturers who can not use Fusion 360 or OnShape in their free versions.

The big problem I'm having is figuring out how to work with existing geometry. This is a basic concept in CAD and I'm sure it's in there somewhere, but I can't find it. For example in "Angle Move," I want to move the angle from one vertex to another vertex. The curser can identify the two vertices, but I can't find a tool to make the move. The other problem, illustrated in "Filler," is using existing geometry to create a solid, in this case a filler to provide a level surface between the two angles. This is really basic stuff in any CAD progam and I can't believe that it isn't available in FreeCAD.

Can anyone direct me to the tools or processes that will solve these problems?

For example in "Angle Move," I want to move the angle from one vertex to another vertex. The curser can identify the two vertices, but I can't find a tool to make the move.

If these are separate bodies, you can use the Std TransformManip tool or add-on Manipulator Workbench. In more complex cases it might be necessary to introduce the concept of Assembly.

The other problem, illustrated in "Filler," is using existing geometry to create a solid, in this case a filler to provide a level surface between the two angles.

Once in the sketch, you can use the Sketcher External tool to project the edges of the existing geometry and use them as a reference for sketching, if that's what you mean.

For such moves you can use the Draft>Move tool with appropriate snaps. Be careful with the working plane.

There is also the addon Manipulator workbench providing such moves.

Here's a suggestion for "fill" for those who like to work out-of-the-box
