Tolerances Don't Migrate SLDPRT --> SLDDRW 1

[phlyx]

This is a question posed to our VAR but no answer yet so I thought someone here might already have run across this.

When you create a part SLDPRT the sketch that you extrude or cut surfaces of the model from can be controlled by dimensions and you can add tolerances on these dimensions. The problem (if it is a problem) is that when you create a drawing SLDDRW from this part those tolerances don't seem to exist. It would be great to put your tolerances on the model and have them appear with the dimensions on the drawing so you can make all your changes on the model and the drawing updates automatically. If you change physical geometry the drawing updates but if you change tolerances it does not seem to follow.

Are we overlooking something here?

Thanks! Happy Friday and us folks down here in Florida really feel for the folks in the north today.... brrrrr

I just tried this using SW2003 and SW2004 and it seems to work fine.

How are you placing the dimensions in the drawing? Are you using "Insert -> Model Items..."?

Phlyx,

First, You need to model the part adding the tolerances to feature dimensions as appropriate. Second, after you create your drawing file and place the view(s) you're going to need to select "Model Items" from the "Insert" menu and import the dimensional information for the part file. Creating dimensional information within the drawing file will only ever show dimensional values. Look in the help file or ask for more info if you'd like.

Some people are quite against this practice but basically this allows for bi-directional changing of the model from EITHER the part or drawing window. It can be tedious and time consuming as well. Coming from planet ProEngineer originally myself, this was simply a way of life although actually the ProE drafting module is quite superior to SW but that's another story.

It's also worth mentioning that you might want to try doing a full rebuild (<CTRL> + <Q>) when you're in the drawing window. This might be your problem too.

The INSERT, MODEL ITEMS works fine but it only works for parts that were created with dimensions such as profiles defined with sketches. Now my question is if I create a rectangle and define the size with tolerances that comes into my drawing fine. If I EXTRUDE this rectange HOW can I place a tolerance on the depth of the extrusion in the part file???

Any help?

That should come through, as well.

Once you make the extrusion, double-click the extrusion feature icon in the feature tree. This should make the feature's dimensions visible (both sketch dimensions and extrusion lengths). Now you can select the extrusion dimension and change its tolerance and other properties.

One more thing about inserted model dimensions:
SolidWorks will not bring through dimensions to a drawing that are not &quot;square&quot; with the drawing view. If your feature is not aligned with a principle plane, you will not be able to bring dimensions into the typical automatic front, top, and side views.

Dang Tick!!! With you guys around who the heck even needs to RTFM???? Hehehehee... worked GREAT! Thanks.

Lucky for you we're in the pre-holiday doldrums here. Too much time on my hands.

Anybody need an API?

Doldrums???? You mean you're not in that panic-to-get-the-work-done-before-the-holidays-because-all-the-customers-want-to-install-the-new-systems-while-they're-shut-down-for-the-holidays syndrome? :O)
