Rotate component/object/body to fit on my CNC bed

eisenmanguitars — Fri, 20 Jan 2023 15:26:44 GMT

I've recently built a fretboard with parameters using Austin Shaners youtube video. My next fretboard needs to be bigger along the Y axis than I can machine on my bed. I tried to rotate the drawing so I could fit it on my bed at an angle, but all the fret slots stay horizontal, and the fingerboard gets skewed. I don't plan to have this problem again, because this is kind of a one-off order, but I would like to learn. My workable area is approx 17.25 x 24. Any tips? File attached.

I am not at all competent in Manufacturing, but I think I would try to solve this there, first, since that is where the requirement comes from. I think you can create a new Manufacturing Model:

You then have to Edit the Manufacturing Model, and Move is available there.

But, if your question is about how to do this in Design, I can help there, as well. Next post

OK, let's look at this from the Design side. Say you do want to rotate the body in Design for some reason. The easiest, most basic approach is to just throw a Body Rotate feature on the end of the design: I would use Move, set to Rotate, and pick the origin Z axis:

But, I suspect what you did first was to try to roll back before the sketch for the fret slots and rotate the body, and this was the result:

So, I looked into that. The root cause for the sketch not following the body after it rotates is:

the construction lines of that sketch are not projected from the body, but from sketch1. This is a perfectly valid way to create a sketch (and, in fact, it is more stable in some cases), but in this particular case, it defeats your purpose of being able to rotate the whole model.

So, next, I went back to sketch1. By deleting this horizontal/vertical constraint, it frees up the sketch to rotate:

That let me dimension sketch1 to get the rotation:

but, that, then, caused other downstream problems:

Hopefully this gives you some ideas about how to make changes to a design. The real moral of the story is: You almost have to anticipate, up front, what kind of changes you might like to make to your design, and test in those changes as you go.

Hi @eisenmanguitars, you can also change the orientation in the manufacturing set-up. There you configure the WCS (work coordinate system) I used a sketch rectangle to drive the selections but there I'm able to change X and Y based on the sketch and not change anything in the model.

Hope that helps.

Wow, this is amazing. However, I can't seem to rotate it in just the xy plane, no matter how many times I try. I turn the wheel for the XY plane after selecting move, but it ends up skewed, like attached picture. I just had my first machine crash...it stabbed itself looking for the top of the model.

I went back and rotated on the axis of one of the upright corners, and I think it worked, I'll try machining this afternoon, thanks!
