Meta
Take-home points and learning outcomes of the 2 tutorials below:
- by learning to sketch in FreeCAD, you can then create any 3D objects imaginable
- Importing part libraries and working with them is a powerful way to do design work using Part Libraries. This can get the casual user to powerful design capacity using real geometries.
Introduction
After these 2 tutorials, you are ready to work on User Contributed Designs. Please pause the videos as needed in order to practice the demonstrated lesson, as these tutorials are dense.
A FreeCAD Manual
The FreeCAD Manual has a different learning approach than the official FreeCAD documentation wiki that makes it more suitable for a first contact with FreeCAD.
Tutorial 1
Tutorial 2
FreeCAD Test
Purpose
This exercise tests your ability to:
- Install OSE Linux
- Download and use library parts in FreeCAD
- rotate, move, and align objects in 3D
- Use the Sketcher in FreeCAD to make features on faces
- Use circular assembly constraints in FreeCAD
- Use Vokoscreen to record instructional screen-casts
- Use KdenLive to edit a basic video, adding images and sound
- Upload videos to YouTube
- Upload FreeCAD source files to the wiki
- Embed videos in the wiki
- Using Disqus and upvoting comments
Test
- Download and install the OSE Linux with FreeCAD, Kdenlive, and Vokoscreen.
- Download 8-hole square tubing (without rounded corners) from the OSE Part Library.
- Use the tubing to create an x-y-z bolted corner cube.
- Record a video of you building the cube, from the beginning, using Vokoscreen.
- When you are done building the cube, create a 1" bolt and nut using the Bolt Library in FreeCAD.
- Insert one bolt through any of the corners, as if you were actually building the cube - using the Assembly Workbench in FreeCAD.
- Tighten the bolt with the nut (just insert the nut onto the bolt).
- Now take any face on the tubing of the resulting cube - and using Sketcher on that particular face - write your initials on that face. Pocket those initials so that they are cut into the face.
- Speed up the file to turn it into a 30 second video using Kdenlive.
- Add Pling by Jaspertine from the Open Source Soundtracks
- Upload the video to YouTube and embed in the section below after the others.
- Upload the FreeCAD file to your Work Log.
- Use Disqus below to tell us how long it took you to learn the FreeCAD tutorials and Kdenlive. Please include any suggestions on the videos. Also, please score yourself 0-100 based on the percentage of the Test points that you have completed successfully - and include that score in your Disqus comment.
At that point - Welcome to the Team, Ms/r. Opensourcer. You now have the basic skills to manipulate objects in 3D and to begin composing useful parts - including your ability to document your work with videos.

Brian Hull completed OSE FreeCAD test 2/16/2017
Test took me 30 minutes to complete. A lot of that time was spent clicking around and learning how the software worked. Overall, FreeCAD worked fine and only had a few glitches for me. I would say pretty good for a free software. This was my first time working with the assembly workbench. There was a few places where I thought the software could be improved but I'll wait until I use it more before I complain too much. I would rate myself a 75 out 100.
Jonathan Kocurek - Completed OSE FreeCAD Test 02/28/17
The FreeCAD took me awhile due to software and also a new interface, features, and multiple unknowns. It took me about 6+hrs figuring out certain issues with sketching my initials on to the metal. Definitely will have to study up on all of the different components of the software.
