MVPEN facilitates the MVIEW command, by using Simple actions and language for defining the viewport properties (size, scale and display). The windowing action is taken in the model space (tilemode = 1), which is more convenient than the viewport model space and zoom scale is specified as 1:xxx, instead of zoom 1/xp.
The viewport display is automatically set to the windowing selection that was made in the model space.
All the viewport specifications are specified via dialog box that keeps the last parameters.
