GstarCAD supports opening and working with several views of the same drawing simultaneously.

After you divide a single window into multiple windows, you can control each window separately. For example, you can zoom or pan in one window without affecting the display in any of the other windows. As you draw, any changes you make in one window are immediately visible in the others. And also you can switch from one window to another at any time.

To create multiple views: View > Viewports  or using Command line> VPORTS

-Choose View> Viewports-In viewports menu, choose 1, 2, 3, or 4 viewports.

-Type h if you want the horizontal orientation, or type v if you want the vertical orientation.

To join two views: View > Viewports> Join or using Command line> VPORTS

-Choose View > Viewports > Join -Click anywhere inside the window you want to keep.

-Click anywhere inside the adjacent window you want to join to the first window.

To restore a named window configuration:

-Type -VPORTS system variable at the command line and press ENTER.

-Then type Restore.

-Then type the name of the window configuration you want to restore.
