Steep infuriating learning curve, Onshape.

[jimbo84]

I’m getting the hang of OnShape now and making some progress.

I’ve drawn this spacer for under the handle on a pan lid.

Essentially it's a truncated cone shape with another cone hollowed out underneath to allow space for the curvature of the glass pan lid.

My question is will it be more of a successful print by printing it the way it’s drawn or flipping it upside down so the top flat edge of the part is on the base of the printer and printed first? Hope that makes enough sense.

Bottom removed edge:

You can revolve that, draw the cross section of one half of the part and revolve around the vertical axis where the screw would be. 1 sketch, 1 revolve, job done.

Below shows the sketch on the front plane with a construction line making a vertical axis, I have used the cross section tool, SHIFT + X, to show the cross section of the complete part on the right plane.

Appologies if you already knew that and were learning the loft tool, I sometimes do things the hard way for an easy part, it's a good way to learn features.

For printing it would be best printed with the top face down on the bed. You will get a better finish on that face. If printed the other way up you'd need supports for the hollow bit underneath. On the how to drawvit, another way is when extruding it there is a draft angle option to obtain a taper.

Thanks, that’s helpful. I drew it using multiple sketches and adding planes in, sounds like I’ve way over complicated it.

Thanks, as it turns out I didn’t need to ask the question here anyway, when I loaded it into the slicer it brought up a warning saying it wouldn’t print without supports. I’m very new to the slicer and didn’t realise it told you stuff like that. I’ve flipped it in the slicer and it seems ok. I’ll hopefully have time to print it tomorrow and see how it comes out.

It’s printed, there are a few imperfections in the print, not sure why but it fits well measurement wise so happy about that.

Not sure how well the PLA will cope with the heat but time will tell.
