Unretrievable Models and Assemblies

  • May 5, 2015

Why is it that when working on an assembly or model and the window is closed or the computer gets turned off / restarted does Creo lose access to models, assemblies, and/or drawing?

 

I keep getting error messages that says the model or assembly cannot be retrieved. How do I re-associate them to the workspace I am working in or make the program be able to retrieve whatever I am working on?

Sounds like you might be a more experienced SolidWorks driver? SW and Creo have a fundamental difference in the methodology in the way it manages work flow data.

1. In Creo, data you are working will be "in Session" (I.E. in memory) and will keep that data "accessible". Even if it's not on the screen it will still be in session. If you "erase in session and/or not displayed" then that data is erased from memory, like it was never retrieved. This is the answer to your question "How would that change in a matter of minutes?

2. Creo has distinct control of where the data you are working on is retrieved from. Unlike SW where it goes and looks anywhere and everywhere for a file with the name it wants, Creo is specific as to the location of the file. You should set and work in your "working directory" and keep all the files there. However you do not have to. A "Search Path" in your config file will direct Creo where to look for the files you need. This the answer to your question Also, how do I fix this?

Below is what a search path line item looks like.

Search Paths in your config file.

Creo does not keep track of where files are located unless you are using PDMLink for data management. You mentioned a workspace above, but I'm going to assume that you meant a Windows folder rather than a PDMLink workspace and that you are not using PDMLink.

When you open an assembly or a drawing, Creo looks for the parts & subassys that it needs in this order:

  1. In session / memory
  2. The folder the parent object came from
  3. The currently set working directory
  4. Any search paths defined in your config.pro file

The simplest way to make sure that Creo can find everything it needs is to keep everything in the same folder. If you have common parts, you can create search path entries in your config.pro file with this context:

search_path [full\path\to\folder]

You can create as many of these lines as you need.

Alternately, you can create a "search path file" (typically named "search.pro") with all those lines in it and then set your config.pro file to use it with this setting:

search_path_file [full\path\to\file]


I hope that helps,

    Ok, now two things.

    First I want to thank you for your help as this is helpful to me.

    Second is another question, we use Windchill and the workspace's we work out of should have an automatic search path and working directory set up. this is why this situation has me perplexed. For the most part this doesn't happen but every so often this situation arises. Now for the question, how with the search path and working directory preset, do I A) prevent this situation from happening and B) get the models to be retrievable once this happens and the model or drawing will not open?

    Again, thanks for the help.

    So you are using Windchill (PDMLink, I assume?), interesting. I don't have any direct experience with Windchill (but we are likely going to implement it soon), so my help ends here. I would have thought that PDMLink would have kept track of everything.

    Sorry I can't help more.

    Are you using Windows WorkGroup Manager or are you pulling the "required" files when you retrieve into your workspace?

    Couple thoughts on the PDMLink angle. If you retrieve required models, whatever is suppressed in model may not be retrieved. When you resume them it would grab them from the vault. If for some reason you lost connection to PDMLink and you were working "offline" it would not be able to retrieve anything not in your wo
