I’m sure this is covered in the forum somewhere, and on YouTube, but I haven’t been able to find it.
To describe what I want to do in my table saw might be difficult to visualise, but if you can answer this much simpler question, I’m sure I can transport the knowledge and technique to my project.
How would I model the rotation of a letterbox flap that rotates on a horizontal hinge on a door that rotates on a vertical hinge? I want to be able to set the letterbox flap at a given angle, then rotate the door on its hinge.
For your interest, the table saw has a framework that hinges to change the angle of cut, then the motor and saw assembly hinges on that frame to alter the depth of cut. The motor, saw and mounting components are a group, and the frame on which they rotate is another group. I can rotate them individually, but both rotate with respect to the XYZ Sketchup axes.
