Command line: ADDPOLYGONVIEWPORT
nanoCAD allows use of this command on the current layout tab in which the viewport should be located, as well as directly from the model space.
Create a polygonal viewport from the model space
When you create a viewport from the model space, specify the vertex points of the polygonal area of the drawing (in the model space) that should be displayed in the viewport.
Option:
| _.Undo | Consistently undo the specified points of the polygonal area. The start point cannot be undone. |
|---|
Command prompts:
| Specify start point: | Specify the start point of the polygonal vertex. |
|---|---|
| Specify next point or [Undo]: | Specify the second point of the polygonal vertex. |
| Specify next point or [Undo]: | Specify the end point of the polygonal vertex and press ENTER. Select the name of layout in Select Layout dialog to insert a viewport and press OK button. Active before running of command layout is highlighted in the layout list. |
| Input or choose view scale <1.000000>: | Input the viewport scale. |
| Specify Viewport Center Point: | Specify the viewport center point. |
