New to CAD, need some assistance with a shape

david_gelb

Hi, I am trying to model a set screw protector and am unsure how to do this. I am creating a piece that fits over a set screw and creates a flat surface to rest against the surface the set screw is clamping onto - basically, to prevent the screw from scratching the surface it is mounting to.

I created the flat surface in OnShape, and then created the cylinder that the screw would sit in, but I am unsure how to give the cylinder thickness. I am not sure I am describing this well, but on the image below, I need to fill the space between the grey and blue cylinders. The set screw would sit inside the inner (blue) cylinder.



If this still isn't making sense, I can try to send other images.

Thank you,
David

When you draw the cylinder, draw two circles in the same sketch. One for the inner diameter, and one for the outer diameter. Then when you extrude, it will extrude with a thickness.

ps, McMaster-Carr sells many types of setscrews that they call "non-marring". They may be useful for your project, or for future reference:
