AutoCAD (LT) opens drawing in new AutoCAD session

Last modified on: 28 de abril de 2020

Problem:

AUTOCAD (LT) is already open. Another drawing is being openend from Windows explorer (double-click) but this starts a new AutoCAD (LT) session and does not add the drawing to the existing session.

Cause:

This has to do with the file extention setting for the DWG extention.

Solution:

Select a DWG file
Give a rightmousbutton click and choose Properties
Find the 'Opens with' part, Click the [ Change... ] button
Change the setting to the AutoCAD DWG Launcher instead of the Acad.exe / ACADLT.exe.
When the Acad.exe / ACADLT.exe is set a new session of AutoCAD (LT) will be started with every double-click. (A Double-click can be seen as a double-click on the Acad.exe /ACADLT.exe)
When the AutoCAD DWG launcher is set, Windows/AutoCAD will check for an active AutoCAD (LT) session and will append to this session.

Another method is to open a drawing from AutoCAD itself. Every newly opened drawing will be opened in the active session.
