I do not speak English, but your tutorials are very useful for me a and are best from all tutorials on youtube for beginer. I learned a lot and i look forward to next tutorials. Thank you very much.
Thanks to your youtube videos I decided to give myself a try and learn something new. I just turned 40, but dreamed some years ago to master at least some basics of 3d modelling. Now it's possible. Can I ask you to show in one of your next videos some basic animations? It might be something as simple as few sticks moving around or along of each other. I'd appreciate such introduction to animation in Freecad.
+mslonik Not an easy task. Most animations are directly programmed in python at the moment. But i will keep on looking and trying if there is something easy and simple to use ...
Thanks much for taking the time to do this Roland. Back to the bearing creation differences. I'm wondering - not having used FreeCAD yet - if it's possible to go back and edit the Part model to add chamfers etc. or is it a 'destructive' process when creating a rotated part. Love the 'digital trashcan' bit BTW :-)
I looked at so many tutorials but chose yous. It is the best. Altough I use Linux 18.04 and you Windows It is no problem. Only thing. I do not know if the pointer/arrow can be made a bit bigger because at times you have to pause and look for it. Altough version 0.8 is quiet different in some cases and then you have to try and figure things out. It would it be great if you could make a new series. Thanks for the series it is really very good.
- At east 4 tutorials in that one video: installing the program, modeling a ball bearing, creating a macro, and the turner's cube. Better if they were split apart. - One problem I see in both workflows for the ball bearing: 3 distinct parameters in the design, ball radius, race radius, and bearing thickness. Change any of those and the change has to be made several places in the model. With the current 0.17 I'm looking at the spreadsheet as a data source for such parameters.
thanks Roland for another very good lesson. I am a self taught conventional machinist and want to use Freecad in my shop. Is it also possible to produce 2D drawings with dimensions because thesa are the type of drawings I use for my work.thanks againTeun
+Teunbaartman1 Yes, you can use the drawing workbench to create 2D-views of part(s). Using "freecad 2d drawing" for the search here on youtube will turn up some videos. You can use the draft dimension tool to apply dimensions or you can use third-party-software. Since i have some leisure time the next 10 days i will be able to do some more tutorials, but i can't promise how fast i can reach lesson 18/19/20 (planned for creating dimensions/drawings).
+Phil B Well, aside from the very-hard-to-answer question if it is the better idea to define chamfers/fillets in the sketch or using extra features (preferrably as last operations with the model) we are still facing a big limitation in freecad. It is called "topological naming". Background: when changing the model FreeCAD will (internally) reorganize the hole model and apply new identity numbers to the edges and faces. Therefore references could be lost/broken. Because it would be a huge time-consuming taks to program a solution for that, this task has not been dealt with yet. That's one of the reasons FreeCAD reacts unexpected when altering the model too much.
I'm able to create two different revolve sketches as you did with the ball bearing outer case and the inner case. when I revolve the sketch of the inner case, only outer case is visible, not the inner. in the dependency graph, it shows the inner revolution depends on the inner sketch as well as on the outer revolution. How can I remove the dependency of inner revolution on the outer? How to solve the above? I'm using the latest version of freecad 0.18 Thank u in advance
I watched all your tutorials. They are great, you seem to be nice person :-) I use freeCAD under Ubuntu to design wood projects like bookstands. I use Part Design Workbench and design all from cubes in 3D (wooden board from cubes, copy, move and resize them). Currently I use Draw dimensions tool from Draft Workbench but the dimensions not look good. Also I am not able to auto generate dimensions anywhere (the Drawing 2D not works to me). In Drawing the freeCAD puts 2D things outside the paper size A4 even A3 ISO (no matter of settings). Also I am not able to add dimensions there or simple 3D model view. I use export to pdf in current 3D view of Part Design with dimensions created with Draft dimensions tool. So I have questions: Are there any plans to make better looking dimensions in 3d view? Are there any plans to make auto generator according to the cubes dimensions (or 3d parts)? Are there any plans to make auto generating table (or spreadsheet) with all necessary dimensions for board cutting? I mean something like below I will be able to print out and give someone who cut me the chipboards: Item | Sizes | Quantity Top | 200 mm x 200 mm x 18 mm | 1 Side | 600 mm x 200 mm x 18 mm | 2 etc...
in 0.17 a new module called TechDraw is introduced for creating 2D drawings. In 0.16.6700 spreadsheet module is re-written allowing putting a table on drawings. in 0.16.6700 "expressions" are introduced to control dimensions/constraints via spreadsheet. At the moment, after spending several months in enhancing the wiki on www.freecadweb.org including uploading some offline tutorials there chances are getting better and better that i will find some time to produce more tutorials. We'll see ...
It would be awesome if there would be tutorial about it. I was trying Drawing but this not works. Maybe this is because Ubuntu package version, don't know. Also I am not able to use spreadsheet effectively, or even export it. I save it as csv but there is no file. Don't know where it is written. EDIT: Under Ubuntu I have freeCAD version 0.15 (revision 4671 git). So it sounds like hope :-)
BPLRFE Hello again, I tested the TechDraw under freecad-daily Ubuntu version 0.17+ and it is not exactly what I mean: - TechDraw allows draw dimensions on Drawing Workbench not get Data values from 3D Parts automatically. - Spreadsheet can be placed on Drawing Workbench but not allow for auto generation (get the 3D Part data values into table). However it is nice step forward.
Spreadsheet also allows to retrieve data from the 3d part (model) and write data back to the model. Look here for documentation: www.freecadweb.org/wiki/index.php?title=Spreadsheet_Workbench
Great !!! This is what I want !!! It works in 0.15 version under Ubuntu as well !!! Export to CSV works as well so I can use it. Thanks !!! Too bad there is no print spreadsheet option, it would be more helpful. The Drawing Workbench not works well, I mean auto scale and positioning of 2D parts. Also I don't know how to place 3D model with dimensions in Drawing Workbench (I use export 3D view to pdf instead to print).
So in 0.19 they broke Part Design WB. It needs now to make a "Body" thing that can't be used in any other WB and objects of any other WB can't be used in Part Design WB without shamanic dances.
Hi. I need to make a pipe with some curves at one endpoint, but the goal is to blow a lead ball without air looses along it's way. I would like to learn to dothis. Thanks in advance.
+martiarenax3 The basic idea would be to do a sweep along a path (either a sketch or a polyline/bezier curve from draft. Apply part thickness tool get a tube.
Thank you for this series of tutorials. I learned so much in such a short time! You are an excellent teacher.
great job once again. Your study format/structure is exceptional.
Great videos.Great explanation in a calm way. I were a complete beginner at CAD a few days ago but now I can design my own objects. Thanks!
I also watched all your tutorials. Thank you very much for your great job.

처음 강의 부터 잘 보았습니다
덕분에 캐드에 다시 흥미를 가지게 되었습니다
정말 감사합니다

Awesome teacher.
Did a test and you can indeed edit the revolution of the sketch, but what a pain!

Well, aside from the very-hard-to-answer question if it is the better idea to define chamfers/fillets in the
sketch or using extra features (preferrably as last operations with the model) we are still facing a big
limitation in freecad.
It is called "topological naming".
Background: when changing the model FreeCAD will (internally) reorganize the hole model and apply new
identity numbers to the edges and faces. Therefore references could be lost/broken.
Because it would be a huge time-consuming taks to program a solution for that, this task has not been

in the dependency graph, it shows the inner revolution depends on the inner sketch as well as on the outer revolution.
How can I remove the dependency of inner revolution on the outer?
How to solve the above?
I'm using the latest version of freecad 0.18
Thank u in advance
i think you need to create an other body for the second revolve
If I print this in a 3-d printer, will the balls be free to move?

Apply part thickness tool get a tube.
thanks mate!.
Your awesome!
always good to know when to add your balls lol
