i created the attached sketch, extruded it out and then marked it up for mortise and tenon joints thinking i could use the subtract tool to create the bodies i need, which i can’t. Is there a quick method for separating out the bodies i need. i usually just draw the joints but i want to find a faster way.
If this is not the best section for this question just let me know and i’ll move it.
One way is to use a series of Split Bodies followed by some Unions.
Thanks for that. And that does solve the problem du jour, but I think I am approaching this wrong. Conceptually maybe.
I got to the drawing I posted, because every time I tried to extrude (a tenon) from a face that was at 75 degrees, it was extruding at 75 degrees and I needed it to extrude at 90 degrees, I tried creating a construction plane, but then I lost all of the layout precision required to accurately layout the tenon.
So can I ask. What is the correct way to extrude at 90 degrees from a face that is NOT at 90 degrees.
If I understand your question correctly and as far as I know, there is no way to extrude from a face that is not at 90°, but there are workarounds. Not sure if this is what you’d like to do.
Yes. Thank-you that is faster than what I finally did.
Which was to create the sketch on the angled face and copy - project - it onto a construction plane, which I then rotated to 90 degrees and pulled the tenon out. But your solution is quicker. Much quicker…
Excellent solution Mike
