Help Part update crashes Inventor 7 repeatable

Help,

I have a part that I was working on and now when I try to edit some features
I get a MS C++ Runtime error and INV crashes every time. Can someone
(preferably Autodesk) please take a look and see if it can be fixed as we
need the part to be edited

Open the part and edit the second feature (ext3) diameter and try to update
the part. I know there are some errors in the design doctor thing but they
are just a couple of failed ref edges that wee just sitting there OK for
ages before?

Part is 1mb and in IV cust files

There is a problem with Ext30 and WP23, this may well be dependant on some
earlier geometry.
When you consider that there are no less than 28 features dependant on
Ext30!
The gravity of the problem is mind boggling.
I would seriously consider remodelling the whole part, removing material
instead of adding feature on to feature, even features without editing well
before Ext30 of the model will not survive rebuild.
After much messing with errors on my own models I now include as much of the
detail in the first sketch and base all of my workplanes etc of this. Yes
this takes time.
All IMO of course, I know its not want you want to hear, sorry.

Brian,

I confirm this issue with Inventor and have logged a request with
development to investigate.

Thank you for supporting Inventor.

I would agree with Laurence that remodelling would help this part. When
I opened the part, sketch doctor reports sketch 23 (split3) & 28
(sweep3) have constraints to unresolved reference geometry. This tends
to add to the instability of the part, particularly since sweep 3 is
related to extrusion3, which is the diameter you suggested changing that
causes the crash.

An added 2¢ worth of opinion, I treat edge tapers like fillets and
chamfers, I place them all after the part is completed. When I edit a
part later, I move the EOP marker above the fillets, chamfers and
tapers, do the edit and then move it back down. This allows all my
sketches to be resolved to square edges and corners. Much easier
construction of the model.

Hi, Brian.

I have to agree with others; start over. The problems start with Extrusion13
and I can't get it to stand up and act right. Possibly one of the drafts is
messing up the face of Extrusion1 (?) though for planar faces it'd be pretty
poor performance unless there's a definition quirk I'm missing that causes it.

Probably unrelated: I don't know if you use the technique frequently (and
know better than I do how it works), but my personal preference is to never
use a sweep like Sweep2. There are a couple of extraneous faces where it
makes the corner. They don't seem to be causing any problem, though, as it
will make a good export at that point. If 'twere me, I'd try to work out a
combination of revolution and extrusions (or even a linear loft) to get the
shape.

Good luck with it.

Duuoohh!!

I was afraid of that. I have never done anything with cast or plastic parts
like this. Mostly machine and fab sheetmetal design so this was a first
attepmt. It may be a wonky model and bad creation techniques but it was all
going soooo well and I was 98% finished (have been working thru this model
and its nmany design variations for 2 days) now it just all falls to bits. I
guess that it wont take me so long to re-model now the design is set but
from Toms post it seems thier is a problem in there somewhere.
I just wanna do a couple of edits then I'm done with this whole darn part.
(Edited)
Thanks for trying anyway guys.

Brian
