Everything was working fine.
I saved the file.
Came back to work the next day and all of these mates decided to stuff me around??
Does any one know why this is happening?
Maybe because when you were working in the assembly the assembly did not rebuild. When you opened it it the rebuild was made.
I tend to press the rebuild button before I save to avoid anything weird like this happening.
Are these any other reasons why this might happen?
When working with unstable models I use ctrl+Q instead of ctrl+B
Ctrl + B. Rebuilds only the features that changed since the last rebuild.
To rebuild all features, press Ctrl + Q. Can take significantly more time, depending on the complexity of your model.
I have tried this but nothing has changed.
The assy was fine when i saved it yesterday but today a lot of mates have changed for some reason.
Are you the only one working on the components of the assembly?
Are you making changes to the components that aren't being saved?
Does this happen in only one assembly, or any assembly you work on?
I am the only person working on this file.
I rebuild/save the file after every change i am happy with in case something crashes or goes wrong so I don't lose any work.
It has only happened to this file but it may have happened once before from memory.
If you do a 'save-as' and save the assembly with a different name, do you get the same errors?
Are the mates blowing up or disappearing?
Is it always the same mate causing the issue?
If I save as a different name i get the same issue.
The Mates say they "cannot be solved" and appear with a yellow icon.
It is always the same mates.
Maybe you could try to mate parts differently for the ones failing.
Are all of or parts fully mated ? or are some parts loose with minus sign infront of them in the assembly ?
How big is the assembly, Brent?
Also, what kind of mates are blowing up? Would they be limit mates?
If you go to the bottom of your mate folder, then scroll up to the first error and suppress it, do the rest solve?
Is automatic rebuild suspended in your file?
Are you using Large assembly mode ?
Are you using lightweight ?
1. I am not sure about auto rebuild
I'm just on my mobile phone so can not check. It is supposed be under the rmc menu when you click on the assembly in the design tree if i remember correctly, suspend automatic rebuild or something like that. Take that off if you have it suspended.
I find this happens sometimes with Flexible assemblies, but possibly that is not the case for your issue. If it's not too much of a P in the A, try deleting the mates that are causing the issue and re-mate. If that doesn't work, possibly try another method of mating the parts, ie. planes instead of faces, edges instead of points etc. Just some suggestions.
Hope this helps,
