i tried but i still did not understand that much. I have to do it because it is required in high school but i have never been very good at this

@goantamihai ,

I think you should be looking into other commands like UNION, SUBTRACT, ECT... to obtain something like:

• Commands for Working With 3D Models

Consider looking at the 3D tutorials from here:  Webinars: Build Your AutoCAD IQ

would it be possible to make the inner circle at 360 degrees and 270? I need this for high school and that's what my teacher said it should be

REVOLVE applied to a Circle can be used to make this kind of thing:

[full] or 

[partial].  So I assume from the drawing that's not an appropriate command for what you want to do.

i mean i tried it in class and it didn't work so basically my teacher just told me to figure it out. but she said the two circles inside need to be revolved one time at 360 degrees and one time at 270 while the outskirts extruded at 10

also is it possible for you to give me this in .dwg?

@goantamihai ,

I think you would benefit more if you learn to use the JOIN, EXTRUDE, UNION, and SUBTRACT commands (which is what you need to recreate).  You can always come to this forum when you have questions.

I suspect what they need is to be used as Paths for SWEEP or EXTRUDE commands.

[goantamihai]

would it be possible to give me kinda of a step by step on how to use them?
