Showing Bores in AutoCAD 2-space Top View

[kahless2005]

I have an object that has a bore and a counterbore through it.

In a 2-space top view, how do I show the bores?

 

[kahless2005]

I meant dimension wise. ie. I have a bore that is 0.5 inches deep.

Some good cad info there, for free.

p37-38 has details of dimensioning, specifically, counterbores. Is that what your after?

There is a worksheet/tutorial for dimensioning somewhere on that site also.

A simple hole note in the top view is an acceptable way to call out the hole with the c-bore.

For example:

Ø.500 THRU, C-BORE Ø.750 X .500 DEEP.
