Really appreciate the knowledge transfer. I predominantly use freecad for personal 3D Printing projects and your videos have been immensely valuable to someone like myself that is self taught with cad and doesn't use it for commercial purposes. Cheers🥰
Good Day MangoJelly Onceagain thank you for your teaching videos. I am trying to make a crown and have a cylinder and using datum plane have managed to insert 4 V's to represent the top of the crown. They are in the positions NSEW. How do I move the datum plane around the cylinder so as to insert more crown points? I value your expert response. By the way I visited Cornwall 20 years ago. What a beautiful area !
such a hard program to learn! i am try to learn as much as i can, i have been at this program for the last 2 weeks now and i feel i have learned nothing so far! but once i learn it i am excited to 3d print
CAD full stop is hard to learn, freecad takes a unique approach trying to be as flexible as possible which causes an extra layer of complexity. Stick with it and learn part design first and that will simplify things going forward. It takes a while but you will get there in the end.
Thanks for the demo. I've watched this video and a few more and I get how to use Datum Planes to attach features to a curved surface, like you do in AddAFeatureOnSideOfCylinder. But I still don't see how to set the precise length of such a feature. Your datum plane in that example was inside the part, and your pad was long enough for the demo. What if you wanted it to protrude exactly 10.5mm from the fillet?
You could use the x,y,z offset to position / fine tune the datum plane. Also it's worth noting with such a surface it may be worth looking at a different technique such as the curves work bench sketch on curve. On Tuesday I am releasing a video regarding a build I have been working on and I think it might help with your question. Other ways are to use boolean techniques where you make the features separately as individual bodies and join them together.
I found this very informative but I sort of wished you had started with a simple example and slowly go thru the steps of adding datum planes to objects. The best one I thought in this video was the cylinde with the straw..
Thank you for the tutorial. Can you apply multiple DatumPlanes on an AxisPlane? I did this and FreeCAD did some sort of weird copy of the part I originally sketched on the first DatumPlane. I stopped modeling at that point because I didn't know if that was the intended/expected functionality.
Sometimes when I'm trying to sketch on a datum plane, I need to rotate the object to see what I'm doing. If the plane is skewed at an angle, is there a way to make the view straight on perpendicular to the plane as it initially is right after clicking the sketch button? Thanks!
Good question and one I have over looked. On the top menu you will see a sketch icon with a magnifying glass. Click that to center view. Also available from top menu > sketch > view sketch. Q the S for shortcut key.
@MangoJellySolutions Thanks for the reply! I've only been using the program a couple months and have lots to learn so I'll give this a try. It seems like I tried the magnifying glass and it centered in the screen but didn't rotate to normal, but I could be wrong. Thanks again!
Can you center a datum plane so that it will end up in the center of an hole that sits on a body? I need that to position my sketches that are used for the helix to make threads. currently I can only model threads, when the hole is in the origin. I think a datum plane is what I need here, but they are not centered over my hole.
Funny you should say that I have just been helping someone out with 3D printed enclosure for their Amiga and did the same. Blast from the past seeing all the old connectors such as PCIMA slots and serial ports. Something quite pleasing with creating enclosures and boxes.
@@MangoJellySolutions ha old retro. I'm into digital electronic engineering as a hobby so I want to print cases for microcontrollers and retro pixel animation displays. My 3d printer arrived 2 days ago and decided it was going to destroy itself and went crazy so I filed a return on Amazon and ordered a new one. I was tempted to steal some of the stepper motors off it for some projects I'm planning but I'm too honest. I've already got a few steppers and super powerful servos and more on the way. I ordered an oscilloscope a month and a half ago and customs in Vancouver British Columbia just released it and I can literally hear the Atlantic Ocean from my house haha. It's like 4000km away at the pacific lol
Sorry to hear that all your grownup toys are either on the return or caught up in customs, that must be pretty annoying. Amount of time I have bought from China and been dying to get my hands on it but when they do finally come I l normally leave them in the drawer for 6 months. Electronics is an area I would really like to revisit. My dad was trained in radio and radar maintenance and it was fascinating the stuff he used to bring home. Sounds like you have some interesting years ahead of you with all this kit.
@@MangoJellySolutions yeah. Retired at 42 so I gotta fill the time somehow. My oscilloscope must've flew across the country because I'm due to get it tomorrow. Almost everything I buy for my electronics hobbies are from China. Most stuff is a few weeks but covid lockdowns happened again.
Thanks for the comments. I have just tried and I can also do this in 0.18. I am using the touchpad navigation setting for my mouse control I wondering if your using a different control system like CAD or Blender?
@@MangoJellySolutions ohh i think i just was stupid in that so i didn't experiment... im using Gesture coz it dosn't need any keys ... and inside the sketcher i find that i just have to hit alt to rotate... thankyou so much it gets easy because of you bro
The most difficult thing I met on FreeCAD is to make revolve the DatumPlane around a cylinder buit as Revolution. Thus Creating a solid cylinder by making revolve a very thin rectangle, and place a DatumPlane over its wall and making revolve around that cylinder, placing it to a specific angle different form the XYZ axis.. An User Experience that for me was and still simply horrible. I can't find good explanations/tutorials for.
Unfortunately not but you can create a sketch and project that onto a curved face. If you look on the part workbench you will see a cube with a green 'F' on the front. Click on that and it will ask you the surface to project on and the face to use

You're very welcome! It's been a joy to create such content for such a supportive community. 👍👍😊
Datum plain are excellently presented here. So, kind of you.
GREAT! I now know about Datum Planes.

I could create custom enclosures with that ehh so I could print in two halves with screw holes and pockets for ports and displays

Can datum planes be used to split things in half ?
I have never seen it used that way. A datum plane is normal used to create sketches upon.
when you're inside the sketcher you could rotate the 3d view freely.. i wonder how coz i cant. i have v0.18 .. thankyou so much great explanation
Thanks for the comments. I have just tried and I can also do this in 0.18. I am using the touchpad navigation setting for my mouse control I wondering if your using a different control system like CAD or Blender?

Hold Shift + Right click, you should be able to freecam

Even if i'm too late, i let this hint here: In the Addon-Manager is a workbench called «Curves» That should fulfill your request.
DatumPlane is not a thin surface. It's a plane with localized XY coordinate system. Its length is by implementation, infinite.
Can we make a curved datum plane?
Unfortunately not but you can create a sketch and project that onto a curved face. If you look on the part workbench you will see a cube with a green 'F' on the front. Click on that and it will ask you the surface to project on and the face to use
@@MangoJellySolutions Okay, thank you. 🍻
@@ajdhgsldhdgwielbw736 I will put a video together as there are a number of ways to do it with different tools.
@@MangoJellySolutions Wow, Okay and thanks a lot. Really appreciate the effort and will be waiting for that one to come out on UA-cam. 🍻🍻🍻🔥🔥
Just put it up on the channel ua-cam.com/video/bMhMiPaqH3U/v-deo.html
