Loading CAE data from search folders
If you want to search for files in multiple folders, you can choose to have the software search a set of defined search folders for components and associated files to load. You must use the From Search Folders load option. This option appears in the Part Versions group of the File→Options→Assembly Load Options dialog box.
There are advantages and disadvantages to searching for data in multiple folders.
Advantages
Concurrent engineering workflows are supported.
Team-based analysis is supported.
You can reuse component FEM files and associated CAD part files.
Disadvantages
Load performance is proportionally affected by the number of directories and files that must be searched.
As the number of files and projects grow, search directories must be continuously maintained and kept up to date.
Recommendations
To reduce search times, maintain your files in a separate directory structure from other file types, such as specifications, reports, presentations and so on.
To avoid having each user maintain search paths, system administrators should maintain the search paths in text files.
To have the software search the correct directories, set the search path in the File→Options→Assembly Load Options dialog box to ug_search_dirs.dat. This is the file that the software recognizes. It contains a list of subdirectory names, one per line.
For more information about using text files to maintain search paths, and more tips for using the From Search Folders load option, see Load part versions.
