thru clearance holes

rel 2001. Hole feature (not cut). I'm placing a countersunk clearance hole
in one leg of a U shaped sheet metal part, but the hole goes right through
the part instead of just thru one leg. How can I make it only go thru one
leg? There doesn't seem to be an option in the hole dialogue box for 'thru
next' or 'Up to Surface' or 'blind'.

Thanks,

Dave

Isn't there a radio button on the depth, letting you chose between 'thru all' and
'variable'. In WF, I get 'Variable', not 'thru' anything. I have picked a surface
on which to place the hole and two surface/edge references for position. So, I
pick 'variable', meaning 'blind'. With questions like this, I wish I hadn't
completely dumped the previous version. I know I've done this before, this isn't
that difficult! is it!?! Some Pro/GOOFY trick? (woudn't surprise me a bit)

There is a radio button, but with only one option, thru all. Variable is
greyed out. I've had a number of responses from the prouser community, all
of which say it cannot be done. I have to either make revolved cuts for each
countersunk hole, or else make straight hole cuts and place a chamfer on
them.

One of the things I worry about, especially with sheet metal because of the
already high aspect ratio (large area to small thickness) is the accuracy setting.
Couldn't this also make a small hole act funny?

Can you not create sketched holes, and then drive multiple instances with a
pattern table?

 

You could, but I'd rather create a udf of the sketched hole, as there are
very few patternable holes in my models. Simplest way by far is to create
cuts, and then apply chamfers. Means I can't use a 'shown' diameter
dimension though for the countersink!
