Description
Описание
Инструмент «Круг» создает круг в текущей work plane путем ввода двух точек, центра и радиуса, или путем выбора тангенсов или любой их комбинации. Он берет linewidth and color, предварительно установленный на вкладке «Задачи». Этот инструмент работает так же, как инструмент Draft Arc, за исключением того, что он останавливается после ввода радиуса.
This tool works the same way as the Draft Arc tool, except that it creates a full circumference. To draw an ellipse use Draft Ellipse.
Usage
Как использовать
- Нажмите кнопку Draft Circle или нажмите C, затем клавиши I
- Щелкните первую точку на трехмерном изображении или введите coordinate
- Нажмите вторую точку на трехмерном представлении или введите значение радиуса.
The circle 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 circle can be turned into an arc after creation, by setting its first angle and last angle properties to different values.
Options
- The primary use of the circle tool is by picking two points, the centre and a point on the circumference.
- By pressing Alt, you can select a tangent instead of picking a point. You can therefore construct several types of circles by selecting one, two or three tangents.
- 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 entered the desired values to insert the point.
- Press T or click the checkbox to toggle continue mode. If continue mode is on, the Circle tool will restart after you finish the circle, 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 circle will create a filled face (ДанныеMake Face
true
); if not, the circle will not make a face (ДанныеMake 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
A Circle object shares all properties from a Draft Arc, but some properties only make sense for the circle.
Data
- ДанныеFirst Angle: specifies the starting angle of the circle; normally 0°.
- ДанныеLast Angle: specifies the ending angle of the circle; normally 0°.
- ДанныеRadius: specifies the radius of the circle.
- ДанныеMake Face: specifies if the Circle makes a face or not. If it is
true
a face is created, otherwise only the circumference is considered part of the object. This property only works if the shape is a full circumference.
- For it to be a full circle ДанныеFirst Angle and ДанныеLast Angle should have the same value; otherwise, a Draft Arc is displayed. The values 0° and 360° aren't considered the same, so if these two values are used, the circle will not form a face.
View
- ВидPattern: specifies a Draft Pattern with which to fill the face of the circle. This property only works if ДанныеMake Face is
true
, and if ВидDisplay Mode is "Flat Lines". - ВидPattern Size: specifies the size of the Draft Pattern.
Scripting
See also: Draft API and FreeCAD Scripting Basics.
The Circle tool can be used in macros and from the Python console by using the following function:
Circle = makeCircle(radius, placement=None, face=None, startangle=None, endangle=None, support=None)
Circle = makeCircle(Part.Edge, placement=None, face=None, startangle=None, endangle=None, support=None)
- Creates a
Circle
object with givenradius
in millimeters.radius
can also be aPart.Edge
, whoseCurve
attribute must be aPart.Circle
.
- If a
placement
is given, it is used; otherwise the shape is created at the origin. - If
face
isTrue
, the circle will make a face, that is, it will appear filled. - If
startangle
andendangle
are given in degrees, and have different values, they are used and the object appears as a Draft Arc.
Example:
import FreeCAD, Draft
Circle1 = Draft.makeCircle(200)
ZAxis = FreeCAD.Vector(0, 0, 1)
p2 = FreeCAD.Vector(1000, 1000, 0)
place2 = FreeCAD.Placement(p2, FreeCAD.Rotation(ZAxis, 0))
Circle2 = Draft.makeCircle(500, placement=place2)
p3 = FreeCAD.Vector(-1000, -1000, 0)
place3 = FreeCAD.Placement(p3, FreeCAD.Rotation(ZAxis, 0))
Circle3 = Draft.makeCircle(750, placement=place3)
