O.k., but it you wanted a tighter tolerance for perpendicularity, and placed an additional reference say on the feature's edge or center line with a tighter tolerance, would they conflict or would the second simply supersede the first tolerance?

So this assumes that the XY tolerance is same as that required for perpendicularity, just like having a global tolerance in the title block?

Maybe a better question is what are the common capabilities (tolerance)of each method to hold what degree of circularity.
If I just want a drilled hole, what tolerance should be called out. I ask, because in the past, I would have just dimensioned a hole of size with a given +-, and did not use...
On a simple bock with a hole or boss, I’ve seen three datum references ABC and a single positional tolerance. I understand the need for the xy placement tolerances of B and C relative to the two side planes, but not the top surface A.
Obviously a feature has to be on the surface referenced as...
After reading so much gd&t stuff, it has become apparent that no vendor is capable of accurately drilling a straight hole with a single diameter, what are commonly held tolerances to be applied to holes that are:
drilled
drilled and reamed
made with an endmill
Or is it only for pocketed...
I could cut some material, but wanted to understand the dynamics too. this applies to the FEA too. It would help in demolding as well as I was thinking of the part being molded with a mold opening in the plane of the open C's
the tubes or rods are solid steel.

Tubing Snap Fit
I wanted to make a plastic (Polyethylene, 0.09” thick) snap holder for some tubing (0.625”). It would be hand pressed on, and be allowed to be easily removed. The snaps would be similar to “C” shaped holders for ratchet tools or a Saddle foot chair glide on a tubular chair leg...
I suppose I could use the entities tool to measure the overlap...I just thought there must be an easier way.
It would be nice to have a "extend fang to surface" tool that incorporated gaps and or a weld where they met

I'm making an angled air shoot tube that has a connecting square that fits into a square output tube. The top of the shoot angles down from the connecting square
What I have is essentially an 10" extruded "n" channel. Both sides of this "n" have a cut 2" from the connecting square end, forming...
I think the plane between the boss and walls is the best option if I don't want to draft the faces after the fact, then mirror the boss and ribs. I'll play with the rib tool too.
Thanks for all the advice!

Eltron,
Do you mean what MD suggests, w Insert->Face->Delete?

Basically, I don’t know why my method gave me the gaps.
Going down, you would have to calculate the required wall thickness, which can be a pain, if you are changing box depth dimensions. Though I suppose I could make a...

I will look at the tried using the Insert > Fastening Feature > Mounting Boss function. I'm using SW 2007.
I'll post a pic later, thanks

I have a box with a boss in one corner (some distance from the wall), and I’d like to add two ribs (tangent to the outside of the boss OD, and each perpendicular to the inner wall of the box. I extruded the box and boss with a 1 degree taper.
My question is how to draw the sketch for the ribs...
