Learn how to model this object multiple ways with this comprehensive FreeCAD tutorial! I'll guide you through not one, but four unique workflows to complete this common CAD exercise. We'll delve into both the part workbench and part design FreeCAD workflows, exploring techniques like intersection/common in part and part design, reverse pocket, shape binder, and clone workflow.
Throughout the journey, you'll gain invaluable insights into sketch placement, orientation, attachment, boolean commands, map reverse, changing supports, re-orientating a sketch on a different plane, and much more. Elevate your FreeCAD skills with this beginner-friendly tutorial that offers diverse approaches.

I hadn't thought of using a subshape binder to join a sketch and a cloned sketch. Dang that's useful!

A really nice tutorial, as always! Though I had managed product design teams for many years, I have never done the CAD part, mainly restricting myself into pencil sketches of the product ideas and leaving the ProE experts to figure it out. Now, nearing retirement, I want to know how to design parts using CAD and FreeCAD is the best option for me. Yours is the best tutorial I have come across.

I remember the days of technical drawing and designing from different view points. The finished work used to be a artwork itself. I have worked for a number of companies that liked to do things the old, tried and tested ways 😊 Glad you're enjoying the videos and they are helping you in your journey. Thank you for the kind comment.

I saw your title screen, and went off and modelled it before watching the vid, to see what method you showed matched mine. Answer.. none 😂. I think maybe cos my thinking is more as if I was cutting the object in a toolroom, even tho this is a casting of course. But same still applies, cos I imagine how I would make the mould pattern.

@AtticusDraco 6 ай бұрын

lol That's interesting I too imagined how I would do it before seeing him do it I started with a rectangular bar & 'carved' away what I didn't want/need lol, as though I was in a tool room I went from the outside in He went from the inside out I'm extremely new at CAD lol, I'm thinking, 'I'm gonna start off with a bar anyhow' That's how I approached it His approach was a lot more sophisticated & easier, I believe :)

@TheScotsalan 6 ай бұрын

@@AtticusDraco Yup. The way my brain is wired means I add and subtract to a mass. Also, cos I am a design eng by trade, for this bracket my thought was what other design options would I want. In this case, I thought probably the pitch between the bores. So I put that in my first sketch. so I can change it easily. That is, my first thought was what is this bracket for ? It is interesting how different methods produce the same model, even tho the tought process can be totally different. 👍

in your workflow were you copy the sketch and reposition, you end up with two separate sketches. If you change the dimensions in one, the other does not change. Instead, select the sketch and create a subshape binder. Then position that binder. Now if you update the sketch dimensions, both pieces update.

@eGnarF 6 ай бұрын

In the last workflow would it be possible to skip the cloning of the sketch. And instead make the subshape binder from the "frame" and original sketch and then reposition the binder? Thus saving one step.

Great lesson! Question: Does anyone know when Real Thunders branch, with the "TN" fix will be integrated? I want to commit 100% to FC, but that issue drives me crazy. Thank you for any information!

@depthoffocusmike 6 ай бұрын

The answer is: never! RealThunder's branch is never going to be merged into the main branch; at this point it is a fork. But the TNP fix he has implemented is being treated as a working solution and re-implemented in the main branch at the moment -- with his consultation -- for version 1.0, which is due in February next year. In the meantime I wouldn't let the TNP issue stop you using FreeCAD; there are several ways around it that are not particularly complex and let you produce robust models.

The alternating behavior of the pocket example in the last workflow was new to me. The wiki on the part-design:pocket operation only mentions "When selecting a single sketch, it can have multiple enclosed profiles inside a larger one, for example a rectangle with two circles inside it. But the profiles may not intersect each other. introduced in version 0.20". Is this documented elsewhere with more detail? After watching this video, I came to FC to experiment with simple pad/sketch scenarios and it works as you showed.

@MangoJellySolutions 6 ай бұрын

Ahh yes, it's a shame that document doesn't have a example diagram as it will be much clearer. In part design your sketch can have multiple closed geometry, say a rectangle which is closed and a circle which is again closed. They must not touch, one part of the circle must not lay over, say the edge of the rectangle (intersect). So you can have the circle inside the rectangle. When this is padded you get a rectangle with a circle hole in the middle. If it was pocketed to half the depth into a larger rectangle it would leave a rectangle hollow with the circle still in the middle. So the circle has to be either fully inside or outside the rectangle with no overlap if it's in the same sketch. If the pocket was through all then you would create a multibody object as there will be a retangle void with a floating circle. Which is not allowed in part design but is in the part workbench. I hope that's not as clear as mud. May be worth me doing a video.

Why Symmetrical constraint doesn't work on mine (Version 21.2)? And all lines turned orange. Also don't understand how this constraint makes the double circle move freely.

@byronwatkins2565 6 ай бұрын

I REALLY appreciate your demonstrations, Darren! But, how did you learn all of this? I wish I had a book about how FreeCAD uses origins, placements, positions, etc. to construct the objects. This would be an immense help when computation fails and in planning workflows that don't fail.

@MangoJellySolutions 6 ай бұрын

I have been in 3D for quite a while before freecad so have a base understanding of 3D that is transferable but what realy helps is I come more from an artistic background over an engineering one. So I experiment indepth with tools to get certain effects so I end doinga lot of research. In regards to a book, that's interesting as I am currently working on one as we speak and hope to release it in the first half of the new year.

What's the difference between cloning and Duplicating? When do you use which!!

@MangoJellySolutions 6 ай бұрын

Cloning will take a clone of the original and any changes made to the original will be reflected in the clone. So in this case to keep the same profile. Duplicate is when you want most of it the same and want to save time but you want to add some amendments.

@azuh6472 6 ай бұрын

I think the explanation starting at 18:04 (and related comments about the clone at 15:45) is not correct. We know that the clone has its own placement because the documentation says so and because otherwise you wouldn't have been able to rotate and move it independently of the object you cloned. What actually happens is that when you do the boolean operation, Body is moved inside ClonedBody and its placement is now relative to the local coordinate system of ClonedBody. And, because that placement (of Body) is (0, 0, 0) with 0 angle, the end result is that Body's position and orientation in the global coordinate system is identical to that of ClonedBody. You can "fix" the situation by rotating and moving Body after the boolean operation. Thanks for the video.
