To open multiple AutoCAD drawing files within a single AutoCAD window, ensuring that each drawing opens as a separate tab in the same instance, follow these steps:
- Right-click on any .dwg file.
- Select "Open with" from the context menu.
- Choose "Choose another program."
- In the list of programs, select "AutoCAD". If AutoCAD isn't immediately visible, browse to its executable file (usually located in
C:\Program Files\Autodesk\AutoCAD [Version]\acad.exe). - Crucially, check the box that says "Always use this app to open .dwg files." This ensures that all future .dwg files will open in the same AutoCAD instance.
By following these steps, all subsequent double-clicks on AutoCAD drawing files (.dwg) will open within the existing AutoCAD application, each drawing appearing as a separate tab within the same window.
