Man this is amazing! I never really got a chance to see freecad in action and this is an amazing tutorial!! Thanks!
Glad you like it! FreeCAD is really nice but you have to use it properly and be aware of its limits and some little tricks to make it work the way you want it to work!
These quality tutorials are only possible with people like you who deliver these outstanding exercises - thanks again for allowing me to create my tutorials based on your work. Really appreciated by me and my community of great CAD loving people! 😎
Documentation like this is just as important as the actual program, thanks so much for contributing to the FreeCAD community!
Wow thank you for this nice comment!
And you deserve it, having videos like this makes a huge difference. You and all the other channels that are producing this - don’t be scared to collaborate with each other!
Hope your channel keeps building too
Working example is what I consider more important than all the features. Very good documentation is often the thing that solely determines my choice. Thank you Florian for that, you make it excellent!
Amazing turorial, straight to the point and easy to follow! Thanks!
Awesome! For whatever reason I had never noticed the taper angle on the extrude. That is going to come in so handy. Thanks much for this and all the other videos you have done on FreeCad!
Thanks for the support!
Just jumping into Free CAD....going to be looking into these videos!
Great tutorial - Thanks 😎👍
Going to have to play along with this one when I get home. My FreeCAD attempts have been rather clumsy and heavy-handed. Nice to see somebody use it with some skill. Great walkthrough! Thanks for sharing!
Totally amazing!!
Thank you, Sir!
So einfach kann es gehen. Wenn ich da an meinen umständlichen Weg denke 🥳
Thanks for supporting also here on my English Channel ! 🎉
these are great videos for freecad. Coming from blender to freeCad has been clumsy but i need to learn it simply because blender is great, but not a good CAD program so this channel and all the others doing FreeCad tutorials are greatly appreciated
very helpful ..Thanks!!
This is similar in some ways to a part I want to model very soon, so this video was extra helpful. Thanks!
perfect!!
Thank you so much for also showing this in FreeCAD (my tool of choice). When I saw your Onshape video, I couldn't imagine how to do it (I only very occasionally do construct something to 3D print it and probably forget faster than I learn).
thanks for your support, Ralf!!
Awesome. thanks. 😍
You’re welcome
Awesome! For this particular model, this is a very nice and elegant work-around on FreeCAD's limitation of the thickness command, which by the way made it even easier to deal with the rib pads otherwise breaking through the outer shell (no need to trim excess parts of the pads).
The work-around I came up with was to create the negative of the inside as second body (another tapered and filleted pad, having the ribs as pockets) and to boolean subtract this body from the outer body (still inside part design workbench, but also possible in part WB). This way, also no problems with rib pads on the outside....
Cool 😎
This sounds like another great work around
thank you good
thanks!!
youre welcome
Thanks for the tutorial. Had never used the multitransform tool.
You're welcome, this tool is super useful.
Very good explanation! I just know the page and it looks very good! Greetings from Argentina.
Thanks. This is was very nice project.
Yes it's a cool little exercise
Wow that's very nice. Hope to see more tutorials like this.
Absolutely - in the future there will be many more
@@FreeCADAcademy great to hear. Thanks for the video bdw 👍
Danke. Vielleicht hattest du das Video auch ohne mein Kommentar geplant, aber ich bin trotzdem froh, dass du das Video gemacht hast. Bei mir hat die Wandung trotz vorheriger Verrundung funktioniert, dafür hat sich das Bauteil bei der Erstellung der Rippe komisch verhalten. Die Rippe habe ich genau so erzeugt wie du. Ich werde wohl noch ein wenig testen müssen. ✌️
Gern geschehen!
Ich hatte das Video nicht wirklich vor - heute morgen halb 5 wurde ich wach und hatte eine 💡 Erleuchtung!
Wie ich es in freecad probieren könnte
Genau das gleiche Problem hatte ich auch
Bravo. Hut ab...!
Auch mit FreeCad lässt sich, wenn man die Werkzeuge anzuwenden weiß, so einiges bewerkstelligen. Wenn man dann auch noch weiß, die Schwächen des Programms (Dünnwand) zu umgehen, kommt so ein gelungenes Video dabei rum. Und das dann auch noch auf Englisch kommentiert. Echt sehens- und hörenswert...
Thanks a lot Patrick! We need to get the English Channel running as well ! 🎉
Very good.
Thanks, sir!
I've not ever used FreeCad, not sure why I watched this but I did enjoy the video. Can't understand why the Shell command doesn't work like it should in all other CAD packages. Fantastic work around
When I did it, the thickness command DID work. The only difference up to that point was I used the draft command to get the angle, rather than the taper option in the pad command.
I did then have to use a different workbench for the ribs, because otherwise the rib would poke out of the fillet. I extruded it beyond the body with the part workbench , used the body to cut the rib, then used an array in the draft workbench, before fusing it together.
I recorded various attempts🙂 one of those also was Part and Draft WB
@@FreeCADAcademy Another way to do it is let the ribs poke through, then clean up with defeaturing in the part workbench.
@@sleepib yes but you see where this is leading us..
Had no idea you could taper a pad 🤔
Hello, very interesting for beginner like me.
Thanks Patrick
Thanks for the great video !
How do you get shape after MultiTransform mirror already refined ? I get a line separating two halves
I very much like the video as it contains a few very interesting parts. The problem with adding a filet "too soon" is well known to me. It can drive you completely insane.
How you are using the Multi-Transform tool is just amazing. And I guess the order of first setting inner filets and afterwards extruding the inner parts with the option "up to face" is just genious. So in short: I again learnt a lot.
As you were checking the mass at the end - I'd have one request:
I quite often find myself constructing an asymetric body. However, as often those objects are meant to be used in 3D print, I need to have the "center of mass" of the printed object cebtered to one axis. I know, that the FCInfo macro gives me the information of where the center of mass is. Still, manipulating it is far from being an easy task for me. Is there any good way to do that in FreeCad (or any other tool)? I'd appreciate, if you could tackle this in one of your videos.
Thanks for sharing, nicely done. After some reflexion, I am intrigued has why the inner fillets have not been subject to topological issue, can you explain?
Well. Those fillets are indeed not without risk. If you remove them completely, FreeCAD would not like it.
To be completely safe from Toponaming in this model you would have to do a lot of things differently, unfortunately..
Ich hab's begriffen... Danke für den Hinweis auf dem deutschen Kanal...
Danke für den Support auch hier auf dem Kanal Guido ! 🎉
Hey! I am new to freeCad and having trouble modifying existing parts I import. I can load the model but when I want to sketch I am not sure which tool I should be using to "Project the geometry" of an object to my sketch. Any ideas? I wasn't able to find it on the wiki either. Thanks
How did you cahnge the colours of the planes to be translucid?
Hello. If I want to extract volume(bottle of exhaust/intake manifol of car) I need to plug all the outlets of the solid model, then (theoretically speking) erase one outside surface of the solid, which will make the entire outside of the solid model to fall apart and create only surfacessss and then the inside volume should stay as a solid. I can then use it as a model for the casting core and also test the volume of the bottle....I just cannot find anywhere (user forums or youtube vids.), how to erase a surface from the solid body. Do you have any solution?
Moving the Z up & pad down, I didn't think of that, I like it.
I try to leave all the filleting to last because filleting has caused me more grief with broken sketches etc than anything else. Trying to make changes to sketches above the filleting as it appears in the tree is a nightmare
Yes you should prefer to create the fillets as a last step if possible.
In this case it’s impossible, because filleting in the sketch then drafting gives different geometries than extrusion with draft then filleting
My FreeCad 20.2 release is not behaving as yours is. As I start to draw the Ribs, I have an inconsistency. At approximately 5 minutes into this video, you press "Create Sketch" and select the XZ plane. Your display immediately switches to a view that has the XZ plane visible at the forefront (i.e., half way through the drawing) and you can sketch the ribs directly on the XZ plane. When I do the exact same sequence, my drawing switches to the Front view of the drawing and XZ plane is behind this. It allows me to sketch the ribs but I cannot see them as they are being drawn. Do you know what is going wrong here? Any tips? Thanks for these videos. I have learned so much and much more to be learned.
Came here to ask exactly the same.
update: Menu -> Sketch -> View Section. That fixes it.
awesome. That works! Thanks!@@oscarrodrigues
i dont have the taper angle option
Why do you move the sketch in the Z axis? Shouldnt it move up the y axis?? Or am i misunderstanding something
When I'm drawing the rib, and starting from the XZ plane as in the video, when I choose to pad that sketch everything disappears and I can't see the sketch in any view other than with Sketcher. Anyone got any advice?
Solved myself. All lines were in construction mode. By default I think they are powder-blue lines once constrained. select all lines in the left elements menu and change to normal lines solved the issue.
I downloaded the latest Freecad, and when I got here 5:00 to draw the sketch I couldn't see the points or lines as I drew, I had to delete the sketch and change the draw style to see the sketch. Are there some settings I can change to fix this?
Unfortunately from this description, I can’t tell you what might cause the problem
Menu -> Sketch -> View Section
Edit -> Preferences -> Sketcher -> Display -> Open sketch in Section View Mode (FC 0.20.2)
I had the same exact same problem and was looking for a solution just now.
Why no use the version from Thunderfoot from now on?
my complete rib made by the first transformation ends up as two pieces, your example ends up as one nice solid piece. What am i doing wrong?
@1:47 'Taper angle' is not there
At 4:35 he chooses 1 edge: edge 21, and applies fillet of 12mm. This does nothing at all when I'm following along. I can't figure out how to do what he did.
I followed along, and the weight at the end was 168.1738g. I did this twice and got the same result. The surface of the form came to 80999.5575 mm2, with the volume being 164876.2614 mm3. Any idea what happened?
I think that’s fine and in the tolerance field.
@@FreeCADAcademy I got 168.1724. I get that it's within tolerance but why is it different at all?
Has anyone created a patch or add-on that solves the shell/thicken problem? That's just bad.
I‘m not involved in the FreeCAD development- so I don’t know.
But I agree it’s a nasty problem
Is there someone in the audience that would draft up a structure. I'm willing to pay but I need to work with someone on a one on one basis over zoom or something that I can convey my ideas in real time. Until it becomes apparent what I'm trying to build.
Why don’t you ask in the FreeCAD forum? There are always ppl willing to help
@@FreeCADAcademy Ok I will see what happens
BRep_API: command not done
And some people have the nerve to say FC isn't intuitive and beginner friendly.
well, these people might be right.
I have 4 years of almost daily experience with FC to be able to create these model without much stress..
Why did you change the attachment and made the pad go down instead of just going up from the XY plane?
It's the small things like a "reverse direction" checkbox instead of just typing a negative value that annoy me.
Cuz we don’t have any dimensions on the XY plane, but the dimensions in z+ 40. that’s why I want my sketch to be placed there.
I understand your annoyance but these are things I got familiar with very quickly
@@FreeCADAcademy So it's because the drawing you based this on shows the top of the tray? Changing the attachment of things is something I didn't do so far, but it makes sense this way.

Beats me why can’t they just follow technical drawing rules used by draughtsmen for centuries.
