Polygon
Source file: 3d-polygon.htm
Polygons are
closed lines or loops used to define a boundary. Polygons can be used
to define areas of interest for modelling, filtering and cropping data.
Use this tool to make 3D polygons. To create 2D polygons use
the 
2D Polygon tool.
-
On the Create ribbon tab, go to the Draw group. From the Polygon drop-down list select
Polygon.
The tool panel will open displaying the input fields for the First point.
-
Click in the view window to select the first point or enter values manually in the X, Y and Z input fields and press Enter. Click
to clear the input fields.The Next point drop-down will be enabled, from which you can select the coordinate entry mode as follows:
-
Point - enter the next point's coordinates. -
Length, bearing and inclination - enter the length, compass direction and inclination angle of the next line segment. -
Relative offset - enter the next point's distance from the last point in the X, Y and Z directions.
-
-
Enter as many points as required to build a polygon using the preferred coordinate entry mode, or by clicking on the action plane.
-
Right-click to complete the polygon.
-
Repeat the above steps to create another polygon.
-
Press Esc or click
to exit the function,
otherwise continue creating new edges of a polygon.
The polygon is saved in the cad 
container.
Tip: Create polygons while in top view 
, or use snap modes to ensure the polygon is created in the intended location.
Example of a polygon created using snap to point mode and a completed polygon loaded into the view.
