TREEMAX
Limits memory consumption during drawing regeneration by limiting the
number of nodes in the spatial index (oct-tree).
XLOADCTL
Turns xref demand-loading on and off, and controls whether it opens the
referenced drawing or a copy.
Set Paths for Temporary Xref File Copies
When you turn on demand loading with copy, you can control where copies
of externally referenced drawings are to be placed.
When you turn on demand loading with copy, the XLOADPATH system
variable can be used to indicate the path where copies of externally referenced
drawings are to be placed. The path you specify remains in effect for all drawing
sessions until you indicate a different path. If no value for XLOADPATH is
specified, the temporary file copies are placed in the standard folder for
temporary files.
If you find that referencing drawings over a network is slow, it is recommended
that you set XLOADPATH to reference a local folder, and set XLOADCTL to
2 so that the externally referenced files are demand loaded from your local
machine. Conversely, to minimize the number of temporary files created by
multiple users referencing the same drawing, those users can set XLOADPATH
to point to a common folder. In this manner, multiple sessions of the program
can share the same temporary copies of reference drawings.
You can set XLOADPATH in the Options dialog box and indicate the path
where copies of externally referenced files are to be placed.
To set the file path for xref copies
1 Click Application menu Options.
2 In the Options dialog box, Files tab, select the Temporary External Reference
File Location folder.
The expanded tree view displays the path where copies of xref files are
placed. If no path is specified, the temporary copies are placed in the
location specified by Temporary Drawing File Location.
3 Edit the path by selecting it and entering a new path.
4 Click OK (or Apply) to set the path.
