Draft Polygon

Description
The Polygon tool creates a regular polygon inscribed in a circumference by picking two points, the center and the radius. It uses the Draft Linestyle set on the Draft Tray.



How to use

 * 1) Press the  button, or press  then  keys.
 * 2) Click a first point on the 3D view, or type a coordinate to indicate the center.
 * 3) Adjust the desired number of sides in the options dialog.
 * 4) Click another point on the 3D view, or type a radius value to define the polygon radius.

The polygon is created inscribed in a circle of the specified radius; it can be switched to circumscribed after creation by changing its draw mode property.

The number of sides of the polygon can also be changed after creation by changing its faces number property.

Options

 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * Press or click the checkbox to toggle continue mode. If continue mode is on, the Polygon tool will restart after you finish it, allowing you to draw another one without pressing the tool button again.
 * Press or click the checkbox to toggle filled mode. If filled mode is on, the polygon will create a filled face ; if not, the polygon will not make a face.
 * Press while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Press while drawing to constrain your second point horizontally or vertically in relation to the first one.
 * Press or the  button to abort the current command.

Data

 * : specifies the radius of the circle that defines the polygon.
 * : specifies if the polygon is inscribed in a circle, or circumscribed around a circle.
 * : specifies the number of sides of the polygon.
 * : specifies the size of the chamfers (straight segments) created on the corners of the polygon.
 * : specifies the radius of the fillets (arc segments) created on the corners of the polygon.
 * : specifies if the shape makes a face or not. If it is a face is created, otherwise only the perimeter is considered part of the object.

View

 * : specifies a Draft Pattern with which to fill the face of the polygon. This property only works if is, and if  is "Flat Lines".
 * : specifies the size of the Draft Pattern.

Scripting
FreeCAD Scripting Basics, Draft API, and the autogenerated API documentation.

The Polygon tool can be used in macros and from the Python console by using the following function:


 * Creates a object with the given number of faces, and based on a circle of  in millimeters.
 * If is, the polygon is inscribed in the circle, otherwise it will be circumscribed.
 * One of the vertices of the polygon will lie on the X axis if no other placement in given.
 * If a is given, it is used; otherwise the shape is created at the origin.
 * If is, the shape will make a face, that is, it will appear filled.
