Beskrivning

Detta verktyg ritar en cirkelbåge genom att välja fyra punkter: centrum, radien, startvinkel och slutvinkel.

The Draft Arc.svg Draft Arc command creates a circular arc in the current working plane from a center, a radius, a start angle and an aperture angle. The radius and the angles can be defined by picking points.

A Draft Arc is in fact a Draft Circle with a DataFirst Angle that is not the same as its DataLast Angle.

Usage

See also: Draft Tray, Draft Snap and Draft Constrain.

Bruk

  • Markera punkter i ett tomt område i 3d vyn, eller på ett existernade objekt.
  • Cirkelbågsverktyget ärver Cirkelverktygets funktionalitet för de två första stegen, så du kan trycka på ALT för att välja en tangent istället för centrum eller radie.
  • Nedtryckning av CTRL kommer att snäppa din punkt till tillgängliga snäpp-punkter.
  • Nedtryckning av SKIFT kommer att begränsa din nya punkt i relation till föregående punkt.
  • Skriv in siffror för att manuellt mata in en koordinat.
  • Den skapade cirkelbågen kommer att ha nuvarande linjestil.
  • Nedtryckning av ALT när du väljer slutvinkeln kommer att ändra riktningen till moturs.
  • Om du trycker på ESC så avbryts funktionen.

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.

  • To manually enter the coordinates for the center enter the X, Y and Z component, and press Enter after each. Or you can press the Draft AddPoint.svg Enter point button when you have the desired values. It is advisable to move the pointer out of the 3D view before entering coordinates.
  • The Relative checkbox has no purpose for this command.
  • Press G or click the Global checkbox to toggle global mode. If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system. introduced in version 0.20
  • Press T or click the Continue checkbox to toggle continue mode. If continue mode is on, the command will restart after finishing, allowing you to continue creating arcs.
  • Press S to switch Draft snapping on or off.
  • Press Esc or the Close button to abort the command.

Notes

  • A Draft Arc can be edited with the Draft Edit command.

Preferences

See also: Preferences Editor and Draft Preferences.

  • To change the number of decimals used for the input of coordinates, radii and angles: Edit → Preferences... → General → Units → Units settings → Number of decimals.
  • If the Edit → Preferences... → Draft → General settings → Draft tools options → Use Part Primitives when available option is checked, the command will create a Part Circle instead of a Draft Circle.

Properties

See Draft Circle.

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

To create a Draft Arc use the make_circle method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeCircle method.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

arc1 = Draft.make_circle(200, startangle=0, endangle=90)
arc2 = Draft.make_circle(500, startangle=20, endangle=160)
arc3 = Draft.make_circle(750, startangle=-30, endangle=-150)

doc.recompute()
