Find dimension???

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}{4D}{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

Try changing the dimension tolerance mode to nominal in config.pro and change any
toleranced dimensions in the model instead of doing this in the drawing. Easier to
work in the model anyway. And, with tolerance mode set to nominal, you shouldn't
get any tolerances shown in drawing dimensions, except those you set with
Properties.

Thanks David

The problem is nearly all of the dimensions that appear are +/-0.1
dimensions as with all the drawings I do. I think the way I'm doing it
now is quicker then setting all other dimensions. I found "show
dimension" in part mode but when the dimension is shown you cant
access the properties it only lets you change the value.

In an ideal world you could enter your chosen dimension then the
properties window opens so you could change the value or the tol. I
cant believe this is not contained somewhere?

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:
