2005 sp3 assembly weirdness

I just applied sp3 this AM, now I'm editing an assembly that's been
around for a couple years, the base part is fully defined and can not
move when I try to drag it, as are all but two parts to which I just
deleted a couple of assy mates.

When I drag the one of the free parts the entre assembly moves around,
completely hosing the structure. If I try to drag any of the parts that
just moved SW states that the item is Fully Defined and Can Not move.

Sumptin's broke.

 

Hmm, yeah, that's strange.

Do you have any Fixed parts? (not fully mated, but Fixed with the (f) in
front of them in the tree?)

If your base part isn't fixed, is it mated to assembly planes?

The main possibility that comes to mind (that doesn't require something you
wouldn't expect) is that some part other than the base part is fixed, and
the base part is just mated to other parts which are allowed to move.

I would also check subassemblies, flexible subassemblies and incontext.

Actually, I would also go through and look at all the mates in the top
level and subassemblies. SW has this way of not showing mate errors at the
top level sometimes, and of mates getting lost or at least not shown where
they should be shown.

 

Yes, the base parts is mated to the top level assy planes. Sadly this is a top
level, top-level assy with (according to Assembly Statistics) 591 top level
mates, 483 top level components, 374 bodies (mostly suppressed hardware).

Time to put on my miners hat and start digging...

BTW- I 'rolled back' to SP2 and it made no difference, seems liek I've seen
assembly mates get messed up when saving them to newer versions, this was a
2004 file last week, today is the first time I've tried to edit mates.

Thanks

Looks like something's messed up with one or more of the configs in this assy. It
I go to the Complete Assy with everything unsuppressed (all the fasteners, etc)
things work as they should, if I go to one with all the fasteners suppressed, it's
crapo.

I might look around for the 2004 version of this file to see if it was broken back
then, but I've got work to do...

I've have seen issues here where a mate near the bottom to the tree
causes components at he top to go under defined and float around. I
assume something gets confused in the database as most times deleting
and recreating the same mates or deleting the part then bringing it
back in and using the same mates works ok.

When this happens I usually suppress parts from the bottom up until I
find the one causing the problem.

Sounds like the fasteners are involved in mating the parts, for example
Part A concentric with Bolt 1 and Bolt 1 concentric with Part B. That
would break the A to B relationship when the fasteners are suppressed.


A trick I found a few years ago makes mate analysis a lot easier: Split
the feature tree into 2 panes and activate the Properties tab for one of
them. If you left click on a component, the Properties pane will show
all the mates from that component to any other components. If you
Control Left Click on another component, its mates are added to the
list, and any mates *between* the two selected components are shown in
boldface
