Vector > Create > Polygon

Use this menu option to create a variety of polygonal-shaped vectors.
The Create Polygons  button   on the Design and Design Tools toolbars is a shortcut for this menu option. The availability of toolbars is license dependent.

To create an exact polygon:

1. In the Project Tree, select the vector layer on which you want to create the shape.
2. Select Vector > Create > Polygon  or   click to display the Tool Settings: Polygon Creation panel.
3. In the No. of Sides box, enter the number of sides you want in the polygon. A polygon must comprise at least 3 sides.
4. To draw the polygon at a specific angle to the model block, enter the angle in the Angle box: enter a positive angle to rotate the polygon counter-clockwise; enter a negative angle to rotate the polygon clockwise.
5. In the Polygon Centre area, enter the coordinates for the centre point of the polygon in the X and Y boxes.
6. Enter the radius in the Radius box. A preview of the polygon is displayed.
7. Click Create.
8. Click Cancel to exit polygon-creation mode.

To create an approximate-sized polygon:

1. In the Project Tree, select the vector layer on which you want to create the shape.
2. Select Vector > Create > Polygon or click  to display the Tool Settings: Polygon Creation panel.
3. In the No. of Sides box, enter the number of sides that you want in the polygon.
4. Move   the cursor to the position at which you want to create the polygon.
5. Click and drag the cursor to create the polygon.
6. Release the mouse button to draw a preview image of the polygon.

   The centre of the polygon is identified by a blue dot, the rotation handle is identified by a green dot, and the resizing handles are identified by red dots.
   
   

7. To move the centre point of the polygon:
   1. Move the cursor over the blue handle. The cursor changes to .
   2. Click and drag the handle to reposition the centre point.
   3. Release the mouse button.
8. To resize the polygon:
   1. Move the cursor over one of the red handles. The cursor changes to .
   2. Click and drag the handle to move the boundary. The centre point remains in the same position.
   3. Release the mouse button.
9. To rotate the polygon:
   1. Move the cursor over the green handle. The cursor changes to .
   2. Click and drag the handle to rotate the polygon.
   3. Release the mouse button.
10. Right-click the 2D or 3D views to exit polygon-creation mode.
