parts in assy loose their constraints

[chshasa1]

hi all

we are facing a problem regarding some parts constraint within an assembly. 

when we constrain them in the first place, everything looks good (fully constraint, ok).

if we then open the define window of that part again, the constraints are changed (as you can see in the picture).

first there were 3 constraints: 1. coincident, 2 & 3. distance, after reopening the define window. the 2. & 3. constraints are changed to coincident with the target surface as "not in memory".

same happens, if we reopen the whole assembly after saving and checking in.

we are using Creo Parametric 7.0.2.0

thanks in advance

Hi,

what happens when you open Master assembly? Inside the picture I can see SimRep info.

hey Martin

it's the same behavior there.

the target part is in all reps provided.

Hi,

Q: Are you able to reproduce the problem on different assemblies?

Q: Can you record a video showing the initial assembling and then the redefinition and upload it?

[chshasa1]

hi

yes, it happened even in another assembly in the meantime.

here is a video:

can you please check if this works with the link?

Not sure you will get many clicks on that link. You can upload your video as an attachment to a post or use the insert video icon.

Hi,

• the assembly contains multiple occurrences of 3BHE032274R0006.PRT component
• each of these components is assembled independently of the others (why you do not use pattern functionality ?)
• therefore, you need to fix the assembly of all these components

If you want to avoid a tedious component assembling fix, then you need to find out which external references have disappeared from the assembly. If these references are suppressed then you can resume them. If these references were deleted then you have to fix the assembling of all these components.

• 2nd occurrence of 3BHE032274R0006.PRT uses
• 3rd occurrence of 3BHE032274R0006.PRT uses 

  • after cancelling component placement redefinition you can see  message (time 1:55)

hi all

i will close this one, it somehow got resolved by the user itself and never happened again..

thanks for support.
