If the HyDraw CAD ribbon, toolbars, or commands are missing or not loading properly, reloading the CUIX
(Custom User Interface) file can resolve the issue. This guide explains the steps to reload the HyDraw CAD
CUIX file using AutoCAD's CUI (Customize User Interface) command.
When to Reload the CUIX File
Reloading the CUIX is helpful when:
- HyDraw CAD ribbon is not visible
- Commands are missing or not
responding
- The interface resets after an update
- Ribbon elements appear blank or corrupted
Steps to Reload the CUIX File
- If the command line is not visible, press Ctrl+9 to turn it on.
- Type CUILOAD in the command line and press Enter.
- In the dialog box, select the loaded customization file and click Unload to remove it.

- Close the dialog box and restart HyDraw CAD.
- After restarting, type CUILOAD again in the command line and press Enter.
- In the dialog box, click Browse and navigate to the HyDraw.cuix file located in the following directory: C:\Users\<User Name>\AppData\Roaming\VEST\HyDraw CAD <version>\R<version>\enu\Support
- Select the file, click Open, and then click Load.
- Close the dialog box and verify that the ribbon has been reset to the default layout.
- Reopen HyDraw CAD to ensure the ribbon loads correctly.
Additional Tips
- Ensure the CUIX file is not corrupted. You can replace it with a fresh copy from another working
machine.
- Avoid manually editing the HyDraw CUIX file, as it may break command mappings.
