Description
Beskrivning
Detta verktyg ritar en cirkel genom att fråga efter två punkter, Centrum och radie, genom att välja tangenter, eller någon kombination av dessa.
A Draft Circle can be turned into an arc by setting its DataFirst Angle and DataLast Angle properties to different values.
Usage
See also: Draft Tray, Draft Snap and Draft Constrain.
- There are several ways to invoke the command:
- Press the Circle button.
- Select the Drafting → Circle option from the menu.
- Use the keyboard shortcut: C then I.
- The Circle task panel opens. See Options for more information.
- Pick the first point, the center of the circle, in the 3D view, or type coordinates and press the Enter point button.
- Pick the second point in the 3D view, or enter a Radius.
Options
The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts (for version 0.22).
Bruk
- Det primära bruket av cirkelverktyget är att markera två punkter, centrumet och en punkt på omkretsen, vilket definierar radien.
- Om man trycker ned ALT, så kan du välja en tangent istället för att markera en punkt. Du kan därför konstruera flera cirkeltyper genom att välja en, två eller tre tangenter.
- Välj en punkt i ett tomt område i 3d vyn, eller på ett existerande objekt.
- Nedtryckning av CTRL kommer att snäppa din punkt till tillgängliga snäpp-punkter.
- Nedtryckning av SKIFT begränsar din nya punkt i relation till föregående punkt.
- Skriv in siffror för att manuellt mata in en koordinat.
- Om du trycker på ESC så avbryts funktionen.
Notes
- A Draft Circle can be edited with the Draft Edit command.
Preferences
See also: Preferences Editor and Draft Preferences.
- If the Edit → Preferences... → Draft → General → Create Part primitives if possible option is checked, the command will create a Part Circle instead of a Draft Circle.
Properties
See also: Property editor.
A Draft Circle object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:
Data
Draft
- DataArea (
Area
): (read-only) specifies the area of the face of the circle. The value will be0.0
if DataMake Face iffalse
or the face cannot be created. - DataFirst Angle (
Angle
): specifies the start angle of the circle, normally0°
. - DataLast Angle (
Angle
): specifies the end angle of the circle, normally0°
. - DataMake Face (
Bool
): specifies if the circle makes a face or not. If it istrue
a face is created, otherwise only the perimeter is considered part of the object. This property only works if the DataFirst Angle and DataLast Angle have the same value. Note that0°
and360°
are not considered the same. - DataRadius (
Length
): specifies the radius of the circle.
View
Draft
- VyPattern (
Enumeration
): specifies the Draft Pattern with which to fill the face of the circle. This property only works if DataMake Face istrue
and if VyDisplay Mode isFlat Lines
. - VyPattern Size (
Float
): specifies the size of the Draft Pattern.
Scripting
Skriptning
Den skapade cirkeln är ett Del föremå som innehåller en kant med endast ett hörn.
To create a Draft Circle use the make_circle
method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeCircle
method.
circle = make_circle(radius, placement=None, face=None, startangle=None, endangle=None, support=None)
circle = make_circle(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
placement
isNone
the circle 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 as App
import Draft
doc = App.newDocument()
circle1 = Draft.make_circle(200)
zaxis = App.Vector(0, 0, 1)
p2 = App.Vector(1000, 1000, 0)
place2 = App.Placement(p2, App.Rotation(zaxis, 0))
circle2 = Draft.make_circle(500, placement=place2)
p3 = App.Vector(-1000, -1000, 0)
place3 = App.Placement(p3, App.Rotation(zaxis, 0))
circle3 = Draft.make_circle(750, placement=place3)
