I do not see anything like this when I search topics, so here we go.
Best way I know of is to save a model as a parasolid, then that can be opened in previous versions. Is there a better way?
Also, I have no idea what to do about drawings.
We have to work with customers on versions back to 2014. This is how we handle it.
Verify prints are all updated.
Use #task to create PDF"s and DXF's of all drawings, if there are not records already stored.
Save the top level assembly as a parasolid or step per customer requirements. (Sometimes IGES)
Put the drawings in a folder along with the neutral file.
Zip it up and either e-mail, cloud or flash drive transfer to the customer.
As far as the format saved out in parasolid is preferred, but I get this alot " I prefer such and such." I gave up a long time ago on trying to tell people that Solidworks is parasolid based etc. I kind of treat it like political debates, I am not going to change their minds so I will spend my time elsewhere..(Like trolling the forum)
Parasolid is best.
Save the assembly and you might get all the parts and assemblies.
You'll need to redo all drawings.
As Frederick said above, Parasolid is the best. You will loose all the associtivity to the drawings. But you may want a dwg or dxf of the drawings so you have some record of that information. And start the drawings in the old version.
We are currently in the process of transferring projects (long story). They each have older seats of SolidWorks and other programs.
They are going to have to save the drawings as DXF and the models as STEP/Parasolid/etc, or whatever their current software can read.

You can use feature recognition on imported part if you need.
If your going from older to newer version, SW does that automatically. Just re-save those SW files under the new version. My question is about going the other way.
Steven, I know. I mean they have older versions (2011) and are getting newer versions (2017, 2018). They will not be able to open anything.
Chris Saller You should still use the Parasolid but you will need to set your version back far enough for 2011 to recognize it!
I do undserstand that, I wrote that.
I didn't mean in that order!
My comment wasn't meant to be insulting. People may not understand that unlike STEP which has a single "version" Parasolid does have different versions. If you are running SW 2017 or 2018 and you export a Parasolid you will have a different version than you would get in SW 2015. I saw "SW 2011" in the comment and simply meant you need to ensure you use set the proper version of Parasolid to export so that SW 2011 can read it.
I had to save Parasolid to older version a few times before.
Also STEP have 3 version now: 203, 214, 242.
The best way to revert to older versions is to use direct edit. With direct edit, the part data isn't encrypted in features, its in the software, so you don't lose the design intent if you have to ditch the history-based features. This is one of the side effects of direct edit that you don't hear mentioned often. The future version ratcheting lock-in disappears. So say you have a Solid Edge 2019 file. Saving the parasolid and reading it in ST6 (several versions old) is completely feasible. You'd get all of the synchronous features, as well as all the face groups set up by the original feature creation. With synchronous, you don't get version ratchet lock-in. Plus the fact that you can deal with imports from SolidWorks better than SolidWorks can deal with imports from SolidWorks.
I really don't understand why there's not this huge exodus.
"Parasolid"... yep.. native Parasolid ignorance among SolidWorks Users is mind-numbing.
Solidworks customer keep sending IGS file.
Its Not Working.
I agree about using the proper version of Parasolid. But, you have to communicate with the receiving end.
From my years of experience with this, not everyone works well with various types of files. There have been many times when they don't know, I will send them 5 different types and let them work it out. This saves time for both of us.
Not sure what you mean by direct edit? You don't mean editing the part using nothing but moving faces and cuts do you?
No, SolidWorks calls it direct edit, but it's not really that at all. SolidWorks creates history-based features for everything, so that's not direct. By direct edit, I mean software that modifies the Brep directly through dimensions and face editing, not indirectly through sketches, dialog boxes, and lists of features. This would include Solid Edge, IronCAD, fusion360, some others.
IGES = "I Guess"
But, to be fair,... IGES and STEP are both good alternative ways to share data with other non-parasolid tools and/or for other ways to share entity data which Parasolid does not support. (or, convoluted import/export rinse/repeat workarounds to clean up faces and gaps)
"I really don't understand why there's not this huge exodus."
..the simple answer, habit, change and the mainstream river of conformity = status quo.
.. to this day (>30yrs) without question,... most of the users I have interacted with would be better off using a Direct Edit tool, period.
OR,.. it maybe... working with a Dumb model sounds stupid?.. .. which brings us to... ignorance is bliss.
I'd call those "flavors" of STEP not versions. 203, 214 and 242 all include different datasets. But that just my opinion.
Paul Salvador Matt Lombard There is no exodus because there is no "pain". No pain. No change. I've been waiting for 10 years now for Dassault to rip the band-aid off. Instead you see a slow bleeding process....

Hey, that dimension driven function means "parametric." ;-) and don't forget the geometry engines that identify face relationships! Combine those two functions and you have synchronous technology! ;-)
...ouch,.. I'm feeling the hair pulled taunt on that band-aid strip everyday..
..btw, the underlaying (SE) covert nature is quite suspenseful.. (using my best english accent)
