Understanding Why AutoCAD Opens a New Window
AutoCAD may open in separate windows due to certain settings or circumstances during the startup process. This typically happens when the program is set to use multiple-document interface (MDI) mode instead of a single-document interface (SDI). Understanding how to manage these settings can help streamline your workflow and avoid unnecessary clutter on your desktop.
Exploring the Multiple-Document Interface (MDI)
When AutoCAD is set to MDI, it permits multiple drawings to be simultaneously open in separate windows. Users often find this feature beneficial for projects that require referencing multiple files at once. However, if you prefer a more organized workspace where only one drawing is visible at any given time, changes can be made to modify this behavior.
Steps to Disable Multiple Windows in AutoCAD
-
Close All AutoCAD Instances: Begin by ensuring that all AutoCAD instances are completely closed. Check for any additional windows that might be running in the background.
-
Launch AutoCAD: Restart the AutoCAD application. It is essential to avoid opening any drawings upon startup at this stage.
-
Create a New Drawing: Once AutoCAD is open, initiate a new drawing to access the command line.
- Set SDI to Zero: On the command line, type
SDIand press Enter. Then, set the value to0. This action changes the setting so that AutoCAD opens in single-document mode.
Adjusting File Association Settings
AutoCAD may also open multiple windows due to file association issues with DWG files. Adjusting these settings can help streamline the process:
-
Access Windows File Explorer: Navigate through your system to locate a
.DWGfile. -
Right-Click for Options: Right-click on the
.DWGfile and select "Open With" followed by "Choose another app." -
Select AutoCAD DWG Launcher: In the pop-up menu, pick “AutoCAD DWG Launcher” from the list of available applications.
- Set as Default: Ensure the option "Always use this app to open .dwg files" is checked before clicking OK. This tells Windows to use AutoCAD exclusively for opening DWG files, reducing the chances of opening duplicate windows.
Understanding the Single Document Interface (SDI)
The SDI setting is crucial for managing how many instances of AutoCAD can be open simultaneously. When set to 1, AutoCAD will only allow one drawing to be open at a time. This setting is particularly useful for those who prefer having a streamlined workflow without distractions from multiple open files.
Switching Drawings and Tabs Efficiently
To enhance productivity, AutoCAD provides various methods for switching between different drawings or layouts. Here are tips to navigate more effectively:
-
Cycling Through Open Drawings: Use
Ctrl + Tabto cycle between currently open drawings. This shortcut enables quick transitions, minimizing the need for mouse navigation. - Using Drawing Thumbnails: Locate the desired drawing or layout thumbnail in the workspace. Double-clicking a thumbnail will open the corresponding document. Alternatively, right-clicking a thumbnail will present you with various options for managing your files.
FAQ
Q1: How can I easily manage multiple DWG files in AutoCAD?
To manage multiple DWG files easily, utilize the Open dialog, hold down the Shift key for consecutive selections or the Ctrl key for non-consecutive selections. This allows you to select and open multiple files at once.
Q2: Is it possible to revert back to multiple windows after changing my settings?
Yes, you can revert the SDI setting back to 1 by typing SDI into the command line and changing the value. This will enable multiple-window mode in AutoCAD.
Q3: What should I do if AutoCAD still opens multiple windows after making changes?
If AutoCAD continues to open multiple windows, revisit the file association settings and ensure that AutoCAD is set as the default application for .DWG files. Additionally, check for any updates or installation issues that may affect program behavior.
