Create a Line with Python Scripting in FreeCAD

Hello friends welcome to FreeCAD tutorial in this tutorial we will learn basic python scripting in FreeCAD. This tutorial is for beginner user to get familiar with python scripting in FreeCAD we will create a simple line with the help of python console. All geometric primitives and shape of part design workbench can be easily used with python console and it is very easy to write Python script using python console.

To create a line element switch to the Python console and type in:

import Part,PartGui
doc=App.newDocument()
l=Part.Line()
l.StartPoint=(0.0,0.0,0.0)
l.EndPoint=(1.0,1.0,1.0)
doc.addObject("Part::Feature","Line").Shape=l.toShape()
doc.recompute()

The above code will create a line in FreeCAD. Now we will understand each line of code.

import Part,PartGui
doc=App.newDocument()
above two line of code loads the Part module and creates a new document
l=Part.Line()
l.StartPoint=(0.0,0.0,0.0)
l.EndPoint=(1.0,1.0,1.0)

First line is a line segment, hence the start and endpoint start point is (0.0,0.0,0.0) and end point is (1.0,1.0,1.0).

doc.addObject("Part::Feature","Line").Shape=l.toShape()

above line of code adds a Part object type to the FreeCAD document and assigns the shape representation of the line segment to the 'Shape' property of the added object. It is important to understand here that we used a geometric primitive.

doc.recompute()

The above command use to Updates the document. This also prepares the visual representation of the new part object.

This how to create to create a line with the help of Python Console. With the help of this tutorial you can create other geometric primitives of part design workbench like line, circle, square, rectangle etc.

Code for create a circle is follow.

import Part
doc = App.activeDocument()
c = Part.Circle()
c.Radius=10.0
f = doc. addObject("Part::Feature", "Circle")
Shape = c.toShape()
doc.recompute()
