Resolve DLL Loading Issue in AutoCAD
Fix an issue where AutoCAD blocks a DLL file located in a OneDrive folder due to security restrictions.
When using the NETLOAD command in AutoCAD to load the EOS CAD tool (a .dll file), you may encounter an error message regarding the file location. If the DLL is stored in a OneDrive folder, Windows may treat it as a remote or untrusted location, causing the .NET Framework to block it.
There are two options for resolving this issue:
1. Option 1: Unblock the DLL
Unblock the file in Windows Explorer.
a. Open Windows Explorer and navigate to:
C:\Users\<name>\OneDrive - Planon\Documents\Autodesk\EosCADTools.dll
b. Right-click the file and select Properties.
c. On the General tab, locate the security message at the bottom:
"This file came from another computer and might be blocked to help protect this computer."
d. Select the Unblock checkbox or click the Allow/Unblock button.
e. Click OK, restart AutoCAD, and try NETLOAD again.
2. Option 2: Copy the DLL to a trusted local path.
Move or copy the DLL to a trusted location if OneDrive continues to block it.
a. Copy or move the DLL to a local directory such as:
C:\DevTools\AutoCAD\EosCADTools.dll
b. Load the DLL from this location using the NETLOAD command.
