#To use this example file, you need to first follow the "Using CadQuery From Inside FreeCAD"
|
|
#instructions here: https://github.com/dcowden/cadquery#installing----using-cadquery-from-inside-freecad
|
|
|
|
#You run this example by typing the following in the FreeCAD python console, making sure to change
|
|
#the path to this example, and the name of the example appropriately.
|
|
#import sys
|
|
#sys.path.append('/home/user/Downloads/cadquery/examples/FreeCAD')
|
|
#import Ex009_Polylines
|
|
|
|
#If you need to reload the part after making a change, you can use the following lines within the FreeCAD console.
|
|
#reload(Ex009_Polylines)
|
|
|
|
#You'll need to delete the original shape that was created, and the new shape should be named sequentially (Shape001, etc).
|
|
|
|
#You can also tie these blocks of code to macros, buttons, and keybindings in FreeCAD for quicker access.
|
|
#You can get a more information on this example at http://parametricparts.com/docs/examples.html#an-extruded-prismatic-solid
