Hi,

Solidworks 2015 sp4

RX diagnostics all green ticks

All parts or assemblies are plain and simple, fully constrained sketches, no incontext, no flexible assemblies ect.

Build bottom up

Having a strange thing(s) happening.

I can open a part, close that part. (no rebuild asked for)

Open an assembly with that part in, induces a rebuild of the part (traffic lights against that part as I chose not to rebuild that assembly)

If I open another assembly with that same part in, that part is not induced to rebuild! (no traffic lights)

This also happens with a sub-assembly that is in two higher assemblies, one higher level assembly induces a rebuild of said sub-assembly, whilst another higher level assembly does not induce a rebuild of said sub-assembly.

Of course Ctrl+Q of the part or sub-assembly induces a rebuild of both the higher assemblies.

If I put the part into a new sub-assembly, this does not induce a rebuild of the part when opening this new sub-assembly

If I put the sub-assembly into a new higher assembly, this does not induce a rebuild of the sub-assembly when opening this new higher assembly

Any ideas?

Thanks

Pete
