creating an arc ring (jewellery)

navpat — Thu, 03 Feb 2022 21:11:55 GMT

hi all,

i've been trying to creating this ring but everytime i revolve a rectangle (1mm x .5mm) it offsets at a weird angle. im trying to make 2 cuts. one for the top arc and one for the bottom. please help me out. i've attached the fd3 file

thanks in advance!

The main issue is that the rectangle drawn in your sketch is offset of the sketch plane (its a 3D sketch). This makes it off of the center axis/plane used when revolving the body.

The quickest fix is to edit the sketch, select the rectangle and right click, then pick 'move to sketch plane'
An observation - this design is full of unconstrained sketches. It would be wise and prudent to define them fully!

I cleaned up unused sketches and draw the arcs in sketch with dimensions.
Emboss the arcs and then used revolve on 2 faces.
I hope I got your design intent correct?

I used 2 faces created by the Emboss feature (yellow in image bellow).
And set the Revolve angle less then 360deg to not cut away the "arc-design"
