- Like so many of my 3d printing and freecad tutorials, I attempt to solve a real world problem while demonstrating how to use FreeCAD and 3D printers. 3D printing has become the go to method for creating objects which previously required machining. In this series I'll introduce you to its spreadsheet, equations, and parametric design. As you observe the model, notice the way the internal cavity has been filleted. This is no accident. Instead of converting the model to a mesh, which is the usual method, it's now quite easy to use the path workbench to generate CNC code for machining. This can be used for such items as machining a rough casting. For embedding in a casting design to facilitate a compartment to contain control electronics in an otherwise hostile environment. Obviously the list goes on from here.
If you liked part 1 then check out part 2.

I feel I'm 'indepthted' to you for making this video. :)
We’re all here to share knowledge. I’m just glad to have unlocked the mystery of parametric programming to so many people. Programs such as this can take the drudge work out of repetitive CAD tasks. `
love your video intro bro
I think I need a step zero. Where did the original box come from, where did the spreadsheet come from?
Regarding the box, I literally created it from scratch in the early parts of this tutorial using the sketcher work bench and the pad tool. Your questions regarding the spreadsheet are best answered by Googling freecad spreadsheet workbench. If you study that section, you will know what I about the spreadsheet. Hope this helps.
@@bcastlar3453 Thanks for the series. I'm just looking at part one here so far. Big help actually. I was wondering what the spreadsheet workbench was. Way different than what I thought.
I do agree with @RW Green though. Maybe on your next thing a brief preface or even written reference to what precedes it would help with the overall quality of the experience. As you know Google, TH-cam tend to drop folks in the middle of these things. Helps a bunch knowing where "start" is and if any given video is going to be worth my time too. Something simple, I know these things take time, a lot of time. Your effort is sincerely appreciated.
Before I go any further here I will go look at the spreadsheet workbench. Link for others - wiki.freecadweb.org/Spreadsheet_Workbench. I'm making an encoder housing that's round on one end to match the motor curvature so I will need to model that too.
Sorry it was not clear to you. It’s a tough call when writing a script to balance clarity with script length. Most of my videos run longer than TH-cam recommends for audience retention. If anything is not clear do leave a comment.
I’ve had my own experience making a quadrature encoder for a lathe chuck though that project precedes my discovery of FreeCAD.
Maybe too late for you but for others in the same boat, watch th-cam.com/video/RNCsazKxviQ/w-d-xo.html
Nice, the enclosure is looking nice. Do you have a thingiverse link?
Thank you for your kind words. Regarding thingiverse, why do you ask?
@@bcastlar3453 I was thinking that we could benefit from having the parametric enclosure model. So that we don't have to create one from scratch ourselves :)
@@davidosterberg First, I would like to apologize for the absence of Part 7, which is the final part in this series. Since Friday of last week, I have been suffering a serious case if laryngitis. This morning I started cutting the audio. I got through the first 1:45, then my voice gave out. Well, I almost made it to two minutes. I will try again tomorrow.
You video has been referenced on the FreeCad Wiki on a page: '''[wiki.freecadweb.org/Best_Practices_with_SpreadSheets Best Practices with SpreadSheets - FreeCAD Documentation ]'''.
Your or your viewers may want to take a look at that page and read/evaluate/learn from it.
It is a wiki so you can change the page, or comment in its discussion tab. You can message me, the guy who made this comment.
Sorry for the late reply. Thanks so much for the link on the FreeCAD website. I checked it out and appreciate the recognition from that site. It’s great to have my work validated in that way.
34,763 mm haha. That’s awfully precise 😏😅
Some of these numbers represent a conversion from U.S. to metric measure. From my experience with scientific endeavors, it’s better to be overly precise than to suffer truncation errors after several calculations.
Hope that clears things up.
