Resolving HyDraw CAD Issues Due to Corrupted User.config Files
Overview:
HyDraw CAD is built on AutoCAD OEM, which stores various pane and palette settings, such as position, docking state, size, and loading behavior, in the user.config file. This file is located within the DefaultDomain_Path_* folder at:
C:\Users\UserName\AppData\Local\Autodesk,_Inc\DefaultDomain_Path_*
If this file becomes corrupted, it can cause multiple issues in HyDraw CAD, affecting its startup process, library explorer, and command functionality. The exact reason for the corruption is unknown, but renaming the affected configuration folder allows HyDraw CAD to regenerate a fresh user.config file, resolving the issue.
