Find dimension???

Question

Hello

How do you find a dimension in a drawing?

Example

I have a threaded hole with hole depth and thread depth, these dimensions are contained in a note (see below)

{0:2 HOLES TAP DRILL }{1:&d46}{2: DEEP} {3:& TAP M}{4:@D}{5: x 0.7 - 6H} {6:&d39}{7: DEEP MIN FULL THREAD} {8:ON A }{9:n}{10:&PITCH[.1]}{11: PCD}

Now the d39 dimension is showing a tolerance of +/- 0.2 but I want it to be NOM because its a MIN dimension.

The only way I have found to change this is to show all the dimensions of the hole on the drawing, change the TOL to NOM then delete all the dimensions that are contained in the note.

Must be an easier way & I'm sure there is.

Thanks

Geoff

Easiertowork in the model anyway. And, with tolerance mode set to nominal, you shouldn'tget any tolerances shown in drawing dimensions, except those you set withProperties.David...

Thanks DavidThe problem is nearly all of the dimensions that appear are +/-0.1dimensions as with all the drawings I do. I think the way I'm doing itnow is quicker then setting all other dimensions. I found "showdimension" in part mode but when the dimension is shown you cantaccess the properties it only lets you change the value.In an ideal world you could enter your chosen dimension then theproperties window opens so you could change the value or the tol. Icant believe this is not contained somewhere?Geoff

: The problem is nearly all of the dimensions that appear are +/-0.1 : dimensions as with all the drawings I do.

So, Geoff, you went into config.pro and set TOL_MODE (tolerance mode) to NOMINAL? Then, you went into your drawing and it was still showing tolerances on newly placed dimensions? on any dimensions?

No you misunderstand David, I'm just pointing out that it is quicker the way I'm doing now.

Show the dimensions of the hole, change the tolerance, delete the dimension. Rather than change the config.pro then have to select which dimensions are toleranced.

Thanks

As an interesting side note - p-Shell API can do this basically as follows:

set dimObj [ps_dim from_ids 39] dimObj configure -bound NOMINAL

Done!

A couple of more lines of code, and you can loop through every dimension in the model, verifiy if it is on a drawing and modify accordingly. Learn more at:
