Description
Beskrivning
Detta verktyg frågar användaren efter en centrumpunkt och en radie. Du kan sedan specificera antalet sidor, och en regelbunden polygon kommer att skapas inuti den givna radiens cirkel. Antalet sidor och om polygonen är inskriven eller omskriven cirkeln kan ändras när som helst i objektets egenskaper. Den nyss skapade polygonen kommer att ha nuvarande linkefärg och -tjocklek.
Punkterna kan markeras med musen i 3D vyn eller genom att mata in koordinater med tangentbordet.
Usage
Bruk
- Markera en punkt på ett tomt område i 3D vyn, eller på ett existerande objekt.
- Om du håller ned CTRL så kommer din punkt att snäppa till tillgängliga snäpp platser.
- Om du håller nedSKIFT så kommer din punkt att begränsas i relation till den sista punkten.
- Skriv in siffror för att mata in en koordinat manuellt
- Om du trycker ned ESC så kommer operationen att avbrytas.
- Den nyss skapade tråden kommer att anta gällande linjestil.
- Polygonen kan visas som en yta eller som en trådmodell, genom att ändra dess visningsläge.
The polygon can be edited by double clicking on the element in the tree view, or by pressing the Draft Edit button. Then you can move the center and radius points to a new position.
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 Enter between each X, Y and Z component. You can press the
add point button when you have the desired values to insert the point.
- Press T 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 L or click the checkbox to toggle filled mode. If filled mode is on, the polygon will create a filled face (DataMake Face
true
); if not, the polygon will not make a face (DataMake Facefalse
). - Hold Ctrl while drawing to force snapping your point to the nearest snap location, independently of the distance.
- Hold Shift while drawing to constrain your second point horizontally or vertically in relation to the first one.
- Press Esc or the Close button to abort the current command.
Properties
Data
- DataRadius: specifies the radius of the circle that defines the polygon.
- DataDraw Mode: specifies if the polygon is inscribed in a circle, or circumscribed around a circle.
- DataFaces Number: specifies the number of sides of the polygon.
- DataChamfer Size: specifies the size of the chamfers (straight segments) created on the corners of the polygon.
- DataFillet Radius: specifies the radius of the fillets (arc segments) created on the corners of the polygon.
- DataMake Face: specifies if the shape makes a face or not. If it is
true
a face is created, otherwise only the perimeter is considered part of the object.
View
- ViewPattern: specifies a Draft Pattern with which to fill the face of the polygon. This property only works if DataMake Face is
true
, and if ViewDisplay Mode is "Flat Lines". - ViewPattern Size: specifies the size of the Draft Pattern.
Scripting
See also: Draft API and FreeCAD Scripting Basics.
The Polygon tool can be used in macros and from the Python console by using the following function:
Polygon = makePolygon(nfaces, radius=1, inscribed=True, placement=None, face=None, support=None)
- Creates a
Polygon
object with the given number of faces (nfaces
), and based on a circle ofradius
in millimeters. - If
inscribed
isTrue
, 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 is given.
- If a
placement
is given, it is used; otherwise the shape is created at the origin. - If
face
isTrue
, the shape will make a face, that is, it will appear filled.
Example:
import FreeCAD, Draft
Polygon1 = Draft.makePolygon(4, radius=500)
Polygon2 = Draft.makePolygon(5, radius=750)
ZAxis = FreeCAD.Vector(0, 0, 1)
p3 = FreeCAD.Vector(1000, 1000, 0)
place3 = FreeCAD.Placement(p3, FreeCAD.Rotation(ZAxis, 90))
Polygon3 = Draft.makePolygon(6, radius=1450, placement=place3)
