OSE Developer Test

Programmatic solution to the OSE Developer Test.

• Requirements
• Pre-Requisites
• Usage
• Dependencies
• Limitations
• Future Development

Requirements

• Import 8 hole tubing from OSE Part Library and build a cube
• Fasten a bolt through one of the corners with a nut
• Pocket initials into any face of any tube

Pre-Requisites

Download Tubing Library by running the following shell script:

./download-tubing-library.sh

This should create a Tubing Library directory inside the ose-developer-test directory.

Usage

Import ose-developer-test.FCMacro into FreeCAD.

Fasteners Workbench

This macro depends on the Fasteners Workbench and was tested with commit ab74422.

Limitations

• Fasteners Workbench must be loaded in the FreeCAD GUI before executing the macro; otherwise you'll get the following error:

Traceback (most recent call last):
  File "path/to/ose-developer-test.FCMacro", line 345, in <module>
    main()
  File "path/to/ose-developer-test.FCMacro", line 45, in main
    create_bolt_and_nut_through_corner_of_cube(last_tube)
  File "path/to/ose-developer-test.FCMacro", line 146, in create_bolt_and_nut_through_corner_of_cube
    FreeCADGui.runCommand('FSISO4014')
<class 'Base.FreeCADError'>: No such command 'FSISO4014'

• Selecting different tubing from the tubing library (e.g. 7 hole tubing.fcstd) doesn't properly align the bolt and nut through corner of cube

Future Development

Future development may include:

• Allow users to select which tubing to create the cube with through the FreeCAD GUI (see Limitations)
• Parameterize initials and allow a user to enter their initials in the FreeCAD GUI
  • This would likely involve using FreeCAD's Text feature rather than using the Sketcher workbench to manually layout geometries and constraints as suggested by OSE
