Command: RESIZEVIEWPORT

This function resizes the viewport to the size of the rectangle enclosed by two picked corners. If the viewport is clipped, the program unclips it. 

Command: VIEWPORTFROMMODELSPACE

This function makes a viewport in paper space from drawn or selected shapes in Model Space. The shape can be preselected.
The program works only in the top view. In the pop-up dialog window, the user is asked to select the scale, layer, and layout. The last used layout is selected by default. 

Command: VIEWPORTBOUNDARY

This function generates in model space a boundary of any shape of the selected viewport in paper space.
The program works with clipped and not-clipped viewports of any shape (including viewports clipped with circles, splines, ellipses, or untypical shapes).
The boundary is made on a separate layer named "_VP_BORDER_TMP_". 

Command: VIEWPORTUPDATE

This function updates the displayed extent in the selected viewport according to the new location of the previously generated viewport boundary and moved in model space.
To update the viewport, the user must generate a viewport outline first by the VIEWPORTBOUNDARYBLOCK function.

Command:   VIEWPORTBOUNDARYBLOCK

This function does the same as the VPB function, but the boundary is inserted as a block. This function allows only one instance of BoundaryBlock. If the user creates a new Block from another viewport, the old block from the previous viewport is deleted.
