Close all instances of AutoCAD and CADWorx. Step 2: Navigate to the folder containing your project database and specification files (often C:\CADWorx Projects\YourProject\Specs\ or a network share). Step 3: Look for files with the same name as your spec .mdb but with extensions .ldb or .laccdb . Example: if your spec is 300lb_steel.mdb , look for 300lb_steel.ldb .
