Description

The Draft Line tool creates a straight line defined by two points. It uses the Draft Linestyle set on the Draft Tray. This tool behaves exactly like the Draft Wire tool, except that it stops after two points.

Line defined by two points

Usage

  1. There are several ways to invoke the command:
    • Press the Draft Line button.
    • Select the Drafting → Line option from the menu.
    • Use the keyboard shortcut: L then I.
  2. Click a first point in the 3D view, or type coordinates and press the Enter point button.
  3. Click a second point in the 3D view, or type coordinates and press the Enter point button.

Options

  • Press X, Y or Z after the first point to constrain the second point on the given axis.
  • To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component.
    • You can also define the polar coordinates of the point by giving a value to "Length" and "Angle". Click on the checkbox next to "Angle" to constrain the pointer to the specified angle.
    • You can press the Enter point button when you have the desired values to insert the point.
  • Press R or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the second point are relative to the first one; if not, they are absolute, taken from the origin (0,0,0).
  • Press T or click the checkbox to toggle continue mode. If continue mode is on, the Line tool will restart after you give the second point, allowing you to draw another line segment without pressing the tool button again.
  • 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 Ctrl+Z or press the Undo button to undo the last point.
  • Press Esc or the Close button to abort the current command.

Notes

Properties

A Draft Line object has the same properties as a Draft Wire object.

Scripting

See also: Draft API and FreeCAD Scripting Basics.

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

Line = makeLine(p1, p2)
Line = makeLine(LineSegment)
Line = makeLine(Shape)
  • Creates a Line object between points p1 and p2, each defined by its FreeCAD.Vector, with units in millimeters.
  • Creates a Line object from a Part.LineSegment.
  • Creates a Line object from the first vertex to the last vertex of the given Shape.

Example:

import FreeCAD as App
import Draft

_doc = App.newDocument()

p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1000, 500, 0)
p3 = App.Vector(-250, -500, 0)
p4 = App.Vector(500, 1000, 0)

Line1 = Draft.makeLine(p1, p2)
Line2 = Draft.makeLine(p3, p4)
_doc.recompute()
