Basic Beginners FreeCAD 0.22 | Lesson 8 | Part Design Basic Exercise 2 | Circular Flange Project
HTML-код
- Опубликовано: 15 июл 2024
- We will tackle the second FreeCAD 0.22 exercise, a circular locking flange. First we learn some more theory of how to tackle such objects, breaking the object down in layers and examining the profiles of each to determine the workflow. We will be creating the object from a technical drawing.
We will learn.
- Reverse engineering and visualization skills.
- Part design pad
- Part design pocket
- Applying multiple sketcher constraints at once
- Creating a sketch on a face.
- hungry selection.
- Circle geometry
- Point on Object constraint
- Diameter / Radius constraints
- How to use construction geometry
- How to import geometry from another profile / sketch
- Multi-solid error and the reason why
- Fillets
- Scenario of a failing fillet and how to fix.
- Alternative workflow for the model

Great course so far! Your helping me get started. Thank you!
Excellent, glad your enjoying and good luck on your journey.
We do enjoy your course! Thanks, Darren. Another great lesson, very clear, thorough and to the point. Please proceed with your videos, we need them as air.
Thank you so much for your support Vladimira, appreciate the kind words :)
I view the all 8 videos.....many thanks that's help me to fixe some knowledges about freecad basics
Great to hear, more to come soon :)
Your videos are the definitive way to learn FreeCad. If I may ask; What is the minimum Mac OS to run the 0.22 version of Freecad?
Thank you so much. Regarding Mac OS I would imagine it would be backwards compatable with most to an extent.
I had to go back to the stable version to find the constrain point onto object button (I could find it in the toolbar right click -> customize -> toolbars and scrolling down to it, but nothing I did would add it to the toolbar). Adding the first circle worked fine, but I just couldn't get ahold of the button to constrain the three remaining ones. Is this just a quirk from the nightly version I running or am I doing something to cause it?
(Also: great tutorials, really appreciate them being as thorough as they are and explaining why things break or won't work!)
I just used the 'constrain coincident', in the tooltip it mentions now that it allows you to "fix a point on an edge".
Ahh, just revested this as I did a bit of digging. Looks like they have changed the tool. Now the coincident and the point on object constraint are both on the same tool. Looks like I am going to have to reshoot some of this video. I though this may happen as I am trying to get in early lol. Oh well not a big issue. Glad your enjoing the videos :)
Using 0.22 (37928) and I do not seem to have a "constrain point on object". I presume that this is the same as "Constrain coincident". Seems to do the same thing.
This is different constraint. I have had a look at the version I have which is a later one and it is there. Looks like an arc with a point on it.
How do you have FC configured that you have to enter the radius of a circle and not the Diameter? I only have diameter option for circles.
I HAVE BEEN WATCHING YOUR VIDEOS FOR QUITE A WHILE NOW, MY FREECAD COMPUTER FINALLY CAME IN YESTERDAY AND TODAY I WAS ABLE TO DOWNLOAD AND START TRAINING IN FREECAD. SOMEHOW IN ALL MY BUMBLING THE "PLANE SELECTION IN 3D VIEWING AREA" HAS DISAPPEARED, NOW I AM UNABLE TO DRAW ANYTHING. HOW HAVE I GARBAGED THIS UP. I UNINSTALLED AND REINSTALLED AND THE PROBLEM STILL PERSISTS. ANY IDEAS??
Why would you not just sketch a cross section and revolve?
Just got to the end... Lol. Yes you would.
Good tip to set deviation locally instead of globally in preferences. You are certainly a TouchPad ninja. I need the mouse for my modeling.
That's how I would've done it too, but I used a polar pattern to create the 4 holes instead of 1 sketch.
‘cuz this is a beginner video. :)
Revolve is simple to you but strange and mind-bending to a noob. I should know, I’m one of those noobs! :)
One downside of using revolve too early in your CAD learning is that you may over-use it and end up generating faulty geometry that causes errors. Ask me how I know. :) FreeCAD is a very powerful program though the error messages are unfortunately written mostly in Greek as far as I can tell. The errors rarely say anything helpful and searching online for them is hit or miss. Several times I’ve run into an error and had to rebuild the model from scratch because I couldn’t decipher how the error could be fixed.
When you’re a beginner: start simple!
I've just drawn something similar but with a rectangular base, and spent ages creating loads of constraints to position them. A cross section and revolve wouldn't have worked for that, but I assume I could have drawn a rectangular construction line for the four holes, instead of a round one.
My cunning plan has been revealed lol :) Guess what the next video is about.
