How to export cad step / iges

Whilst I can only speak for myself, that functionality would have saved me a great deal of time for one of my projects. 
We were updating some tooling fixtures that were created over a decade ago, at a different facility, in a different state.

The original CAD models had long since been lost in a digital sea between the dozen or so engineers in that department over the years.
So I found myself with an old program which contained an imported model, and needed that model to be exported so it could be updated in a CAD software to our current revision. Since I didn't have the option I just remodeled it from scratch based on the numbers in the old DMIS program, then updated it all and re-imported it. Starting with an IGES would have made things just a tad faster! 

It it's not a "secret", why isn't there a menu button available for the IGES format??  The IGES option exclusively appears within the "save as" Windows prompt.   It is not communicated whatsoever in PCDMIS anywhere else, not even in help (per pic below).

With those two facts (no menu item & not in help); it's definitely not clearly described nor communicated.  What else would you deem it if it's not communicated at all within the software?

Also, WilliamL and myself just affirmed later version of PCDMIS (using same license, I tried 2023.1) it's not present, whereas within version 2018R2 it is. So it IS clearly revision dependent.

Here's Help file excerpt (from within 2018R2 which it works on).

Don Ruggieri my license file doesn't mention anything about IGES, here's my modules list.

"I've needed (IGES Part CAD output) because my organization doesn't have effective configuration management for our customer's cad data."

Similar to what ArkansasBeeper said.  We don't have the original CAD as our engineering department is organized by customer/client and each group has their own methods of madness for controlling the CAD files.  Current products haven't been changed in 15+ years. Add employee turnover. Voila, we don't have the native cad. But there it is, clear as day, in our locked-down production-validated routines.

I apologize, I was not trying to be sarcastic.  I was just trying to clarify some perceived misconceptions and I failed at that.   It is somewhere between "secret" and "marketed and publicized".  It is a feature which was not intended for widespread usage, so maybe that falls closer to secret than I was trying to indicate.

I just tested with 2023.1 on my own system and it is present there as well.  And when it is enabled, it is not tied to an IGES reference in the license.

As for the help file, you can see the Part Model export section, the one we are discussing here, does not include IGES.  The PointCloud section includes an IGES option, but that is altogether different.

What is this "secret/non-marketed/non-publicized" license option you don't speak of?

I honestly don't recall.  I just remember that about 20+ years ago when it was removed, I was one of the ones that complained.  This is not the only instance where a function was piggybacked onto another (entirely unrelated) license option.  The reason is that for little used capabilities, it is not worth the exercise of going through and adding more license options.  Someone would have to reverse engineer the options to figure out which this is tied to.

If you get creative with the custom probe builder there is an export IGES function in the probe assembly tab.

You can rename .cad to .draw (and vise versa). Import what you want into the probe builder, make it a tip, assembly it in a probe and export the probe as a whole IGES file.

I do have the CAD Output option on my license, so this maybe why I can do this.

This allowed me to get some old models out of old programs where we no longer had the original CAD files.

That's quite the tip!
