VScad3 Geometric Entities

2.4.4 Polygon mode.

This mode is used for placing Polygons in the model. Polygons can be drawn by clicking the left mouse button in a geometry view. The exact creation sequence depends upon the type of polygon being created. When entering points, it is possible to switch to "View" mode and pan/zoom/rotate the view, and then go back to Polygon mode and complete the polygon in progress. For circle polygons, the current attribute setting for "Facets" will determine the smoothness of the circle. The higher the number of facets, the smoother the circle. The "Facets" setting (as well as the default entity color and fill pattern) can be accessed via the main "Resources / Attributes..." menu. Polygons are similar to Polylines, except that Polygon perimeters are always closed, and Polygons are filled (with a solid fill or cross-hatch pattern).

"Type" : Use this list to select the type of polygon to create:
"Freehand" : Click the left mouse button in a point-to-point fashion to enter polygon segments. Click the right mouse button to finish. Polygon edges may not cross over themselves.
"Rectangle" : Click the left mouse button to enter the first corner position. Then click the left mouse button again to enter the opposite corner. The rectangle is then closed (and constructed) automatically.
"Circle (Diameter)" : Click the left mouse button to enter the first diameter position. Then click the left mouse button again to enter the opposite end of the circle diameter. The circle is then closed (and constructed) automatically.
"Circle (Radius)" : Click the left mouse button to enter the circle center point. Then click the left mouse button again to enter the radius end. The circle is then closed (and constructed) automatically.
"Circle (3 Point)" : Click the left mouse button three times to enter the points. A circle is then automatically constructed such that it passes through the three points. The three points can not be collinear (in a straight line).

"Z Plane" : This specifies the Z coordinate at which to place the polygon coordinates when the left mouse button is clicked in a view.

"Geometry..." : This will bring up the "Polylgon" geometry dialog. This dialog is identical to the "Polyline" geometry dialog. See Section 2.4.3B .
