Description

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

How to use

  1. Press the Draft Line.svg Draft Line button, or press L then I keys.
  2. Click a first point on the 3D view, or type a coordinate and press the Draft AddPoint.svg add point button.
  3. Click a second point on the 3D view, or type a coordinate and press the Draft AddPoint.svg add point button.

The line can be edited by double clicking on the element in the tree view, or by pressing the Draft Edit.svg Draft Edit button. Then you can move the points to a new position.

Fusing single lines

If several connected Draft Lines are selected they can be fused into a wire by pressing the Draft Upgrade.svg Draft Upgrade tool; however, this wire will not be editable. To create an editable wire, use Draft Upgrade.svg Draft Upgrade three more times on the new shapes (wire, closed wire, face). You can also fuse the original lines with the Draft Wire.svg Draft Wire tool.

A wire can also be created from a single line by adding another point anywhere along its length. To do this, press the Draft AddPoint.svg add point button, and click anywhere on the line.

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 Draft AddPoint.svg add 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 Draft UndoLine.png Undo button to undo the last point.
  • Press Esc or the Close button to abort the current command.

Properties

A Line object shares all properties from a Draft Wire, however, only some of these properties are applicable to the Line.

Data

  • DATAStart: specifies the start point.
  • DATAEnd: specifies the end point.
  • DATASubdivisions: specifies the number of interior nodes in the line. available in version 0.16
  • DATALength: (read-only) specifies the length of the segment.

View

  • VIEWEnd Arrow: if it is True it will display a symbol at the last point of the line, so it can be used as an annotation line.
  • VIEWArrow Size: specifies the size of the symbol displayed at the end of the line.
  • VIEWArrow Type: specifies the type of symbol displayed at the end of the line, which can be "Dot", "Circle", "Arrow", or "Tick".

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, Draft

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

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