Ok i feel pretty dumb here to start off :(
well its been a while since i had to do actual hard drawing in my drafting class, and i need alittle bit of help to find some center points. now my teacher never really taught us this or he did 2 years ago i forget. but i cant seem to find a way to get the center points to a drawing. they come off the actual piece so its like an arch in the drawing. i think you have to add the radius of the circle to another centerpoint on a drawing but i forget :oops:
heres the drawing. i just would like to know how to get the center points that are circled. also figure out how to find those center points period :)

I'm not sure of the official way to do this, but I'd draw perpendicular lines from the arc. Where they cross is the center.


Not sure if that's right though.


Doesn't autocad show you were the centers are when you put your mouse over the arc?

yeah i guess i didnt make this clear enough. im drawing this from scratch. im given the dimension from a worksheet and drawing it on CAD. i need to find the centerpoints of those arcs but i dont know where they start or end. they just give me a radius of the circle.
that any better?
