We have an issue that I'm trying to work on and get a solution to move forward on a current project. Previously when using a pneumatic cylinder, the procedure has been to set the stroke length as a permanent extrusion and not have it flexible. I have created a few new cylinders that have flexible strokes, and then have positions set up as well. We want these cylinders to be available for all projects and to be uneditable, essentially we need them in the library. What is happening is when we place this part from the library and make it flexible in a project the assembly becomes dirty and is requesting to save the file before checking the main assembly back into the vault. What am I doing wrong? Is it not possible to have a library assembly file that is flexible in another project?
Something similar to this website: http://wikihelp.autodesk.com/Inventor/enu/2012/Help/0073-Autodesk73/0460-Assembli460/0536-Represen53...
The only thing is having those hydraulics as library parts.
I think the issue here is that the file is becoming dirty. Not that the file is in Vault.
Perhaps if you posted this in the Inventor forum you would get more responses.
