Reverting to SE V20 from SEwST
Reverting to SE V20 from SEwST
(OP)
Thought I would warn you:
If you revert to SE V20 after saving any traditional mode file in SEwST you will NOT be able to open the file again in V20. I thought this only applied to Synchronously generated parts and assemblies; unfortunately not.
I tried to revert this morning after having had stability issues with the new version, and problems with assembly constraints in the trad environment.

SE and other CADs are not downward compatible. So once saved
a document in SE-ST (internal V100) then there is no way
to return other then using a neutral format (Parasolid, Step).
A document created or converted from traditional mode into
ST mode is also a one-way.

They will never do it because they want to force their users to upgrade. I know every other company does it, but it is still callous.

the word 'every' is not correct when addressing parametric
3D-CAD vendors like PTC/Adesk/Siemens and possible others as
well. The have in common that they lack backwards compatibility.

Ah well, I suppose I'm getting better value from my maintenance subscription!

RE: Reverting to SE V20 from SEwST
They may not even bother with annual mainteneance - after all, you've paid for the license again over 3 or 4 years, so why not just buy a new one then if you need it.
Now, saving as a previous version - that would have been a useful update for SE21 !!

Will SEwST be the end of the "backwards compatible" conundrum?
I hope it is, because then others will have to follow suit.
RE: Reverting to SE V20 from SEwST
V21 (internal V100) will not be able to read a file created by a higher
version. ST does not mean that there are no features it does mean that
there is no history any longer. Also 'Synchronous Technlogy' describes the type
of solver. The word 'synchronous' in 'Synchronous Technlogy' doesn't
refer to a modeling process, but rather refers to what's known as a
synchronous solver. This enables the CAD program solving the explicit and
inferred constraints at the same time. It does not use a history tree, but
rather holds user-defined constraints in groups associated with the surfaces
to which they apply. It can be seen as an extension of what KeyCreator,
SpaceClaim, to name but a few, already doing and what has been implemented in
SE as 'Direct Editing'
Note, however that NX (V6) implemented ST in a complete different way

RE: Reverting to SE V20 from SEwST
I model pipe flanges, pipework, vessels, brackets and frames with a fair amount of sheet metalwork. Individual parts are extremely simple, and build into complex assemblies. It is easy to modify the parts, as most of them contain only 3 to 5 features, so ST offers nothing of value.
To me, ST looks like a different CAD package, and not an upgrade of SE v20. If I was starting with a clean sheet to procure a CAD package for the sort of work I want to do, I would be unlikely to pick SEwST. If I was designing complex plastic mouldings or die castings, it might be attractive.
Even then, for anyone with experience using "traditional" sketch / history tree solid modellers, ST represents a steep re-learning curve.
I don't know why they didn't make it a stand alone product - after all, the ST files are incompatible with the traditional workspace anyway.
RE: Reverting to SE V20 from SEwST
Sorry, my post should have read (without feature history) ... obviously the part will still have features, but they will be a collection of solids/surfaces rather than a specific type of feature (eg. extrude or sweep).
If SEwST can edit 'dumb' solids, regardless of CAD vendor or version, it should be able to do the same for its own product. Only time will tell, but if that turns out not to be the case, then surely the finger must point to SE for forcing that inability.

that's what marketing tells you ... OTH you could do that with V20
as well (with some limitations). The imported part is just a block
no more no less. IMHO you won't see that a file created by SE
Vxx can be opened in SE Vxx - x

RE: Reverting to SE V20 from SEwST
You will have lost some stuff, like any MBD etc but frankly from what I've seen of how they envision ST being used I'm not sure how much of a problem this is.

RE: Reverting to SE V20 from SEwST
convert the "V22" to dumb solid
[...]
or in other words: save it in neutral format (applies even when the
file is an ST mode one). Then you could work on it in ST with all
'features' available or trad. mode (limited to the 'Modify'
commands). A trad. mode file can be converted(!) to an ST mode
file.

RE: Reverting to SE V20 from SEwST
an ST-mode file (block plus hole) exported as .jt will come in
as single block 'base feature' with the hole there but not as
a separate feature. Using 'Feature Recognizer' one can try
to recreate some of the 'features' (not available when using the
ST template on import)
So it's just similar to importing a Step, Parasolid, ...

RE: Reverting to SE V20 from SEwST
I've not managed to get PMI information to show up in a part
after the .jt import. PMI will show up when the .jt file is
viewed by View&MarkUp or one of the JT-Viewers. AFAIK you have
to create a ModelView before the export and check the option
to include PMI data to make this happen.
I've not used it very much so this information may not be
accurate.
