I really wish I could justify the expense of NX.
I deal with loads of import files and just avoid where possible using constraints and instead use defined sketches/points/planes/rotations to move the part to new orientation/positions.
Please, try out the link to the macro I posted above!
It’s not perfect (sometimes duplicates bodies after you used the combine feature which you then can delete) but it does the same thing for you without having to save & reimport everything.
That would be fine if the plastic part you were using ‘just’ needs repairing.
Unfortunately 9 times out of 10 I end up doing modifications to the part design and sometimes massive amounts. It needs fully traceability of what was done and possibly changed again after client approval.
You know all that resurfacing you did, we like it but need a few modifications.
Oh what a shame the history is gone. What would have took 15 mins is now going to take me a day.
You still have the original with the history so you modify that, yes you’ll have to go about all the other saves again but you can get there, not a days worth, unless the mods are massive.
I can relate very well with your remark (I designed injection molds with NX in the past, lot of plastic parts with hundreds of direct modelling features to fix them), and I understand that it is not always possible the approach I suggested, but SOLIDWORKS sometimes decides to “implode” and the only way I found to save the day was export to Parasolid and re-import with a blank history.
SOLIDWORKS has a lot of problems and I think is not worth the saved money in palce of an higher level CAD for those kind of jobs. The level of workaround and instability I saw in SW is unthinkable in NX, which costs three times SW but it is worth way more than that in terms of saved time, headaches etc IMHO.
