Hey Ed,
Yep, decrease. (I'm using mailgate.org (on location contract) and I don't proof much using it.)
I know you wrote about the split part issue and I took note of it but when I've used it, it's pretty good. Although, I still lean towards insert part because of past methods and it still makes sense to me it should be this way (if they add sketches, better positioning, coordinated systems,..it will kickass).
And, I agree, the stability of sp3.1 has been impressive!
Otherwise, I have not had many problems except for the typical workarounds due to surface issues (problems with edges, extending edges, trimming in different orders (mutual trim limitations), copy-extend-offsets, edge degeneration (there seems to be tolerance issues again),.... it's driving me knuts)
The wierdiest thing that has happened recently is with insert part. This error showed up when the surface option was checked...
"Some resulting bodies cannot be identified from the saved information."
It went away after I did more work on the model (added features) it refered too but there is no way to track down what is was because I have to move forward, (I have no time to send the data so I sent the error message image and explained). There was nothing wrong with the model (no errors, ctrl-q'd) and in fact it's been stable since last year when I created the skins for the early layout, it's very clean.
