• I found a symbols library very similar to yours on another site. Do you have resellers?

• I loaded my symbols library and tried to use it. I'm getting this error...

"Dialogs are not available because DCL Files are not loaded".
What's wrong?
.
• Will these symbol libraries work with other Autodesk products?

.
• Will these symbol libraries work with metric drawings?

.
• I primarily work with civil drawings where one unit equals one foot. Will these symbol libraries work with my civil drawings?

.
• Can I get a smaller version of a symbols library?

.
• Do you have any other symbol libraries in stock?
  
  
• Are there periodic upgrades available for the symbol libraries?

This fix applies for the full version of AutoCAD:
(For AutoCAD LT, see below)

The "base.dcl" file is probably not loaded in AutoCAD, or AutoCAD does not know where to find it, or there is a problem with it.

First, try loading the BASE.DCL file. Copy and paste this line of text into AutoCAD's command line and press Enter: (load_dialog "base.dcl")

Restart AutoCAD.

If that didn't work, then AutoCAD does not know where to find the file BASE.DCL.

In Windows, click on the "Start" button, then click on "Search", then "For Files or Folders...". Search your hard drive for the file BASE.DCL. Take note of the exact path where BASE.DCL is located.

In AutoCAD, click on "Tools", then "Options" and go to the "Files" tab. Click on the plus symbol next to "Support File Search Path". Make sure your Autocad's "Support" folder is listed there and the path agrees with the path you found after searching for BASE.DCL. If they don't match, modify the path under "Support File Search Path". Restart AutoCAD.

If neither of these work, then the problem is with your "base.dcl" file. You'll need to reinstall AutoCAD.
