Thanks for the video and here is giving the god-algo a kick in the positive direction

Thank you for doing this video., This really opened my eyes to the different. ways the use the 2D offset. I'll probably have to do it a time or two to kind of. Follow the workflow I was able to complete it. Your approach is different. it's obvious that you must be a 3D printer because the way you model using offsets is pretty interesting. You make a great cad teacher.

Thank 4 Axis Printing for this HELPFUL video. At least, the problem is LESS Painful now because the fix works in some cases. Well, it's free. If I want to have a CAD app that works better and more user friendly, I have to pay much more money for Fusion 360! Blender & Platicity are better because they don't have this naming problem but they have their own HUGE problems. Blender is extremely DIFFICULT to do 3d CAD designs and Plasticity is NOT Parametric! I would deeply appreciate if someone could suggest a better app to do 3d Cad design at a resonable price than these 3 alternatives to Fusion 360. Thank you.

İ have an a little model and freecad fillet select extramly slow. Rtx3090 5950x cpu 64gb ram and why

See now I was just thinking about using a slot at an angle trimming a couple edges and mirroring. But then you had to go and introduce the parametric aspect of it with the dependency on the single constraint. You win, that's a good method.

Great tool. I was able to manually install in Windows by unzipping in the Users/User/Appdata/Roaming/FreeCAD/Macro folder. Then using the file named DoPathHelix.FCMacro. Adding shortcut on toolbar just required either moving the icon to an existing icon directory, or better, in a user directory for custom icons. There are some gotchas. Units are assumed in metric, regardless of how you have your preferred units set. If your helix looks funny make sure it is sized the way you think it is. My specific application requires a tight helix around a tight helix and the approximation of selecting a point every 180 degrees around the arc leads to significant bends. I have made a brief go at changing this and am not sure I have found all the terms to change to go from the current two points per rotation up to four or eight. I would appreciate any advice from 4 Axis Printing, and recognize that the low number of samples saves a lot of computation time and works fine in many applications. I will just suck up the wait for answers when I get this sorted.

best.... subcribe

I modeled a plaque almost identical to yours in Freecad 1.0. Problem is, I'm having difficulty creating a toolpath. I'm very new to cnc routing. What tool, what operation, etc. do you recommend for machining the fillets?

Fantastic tool and instructions! This is exactly what I was looking for. Your icon install script works fine on Windows when run from a git bash terminal.

Very interesting, what do you know about top down design in Freecad. To be be able to make small assemblies, using existing geometry for new geometry in non arcane way would be amazing.

I found out that Copilot knows about freecad too, for example ask copilot 'freecad python, how do i create a sketch'

Wow! That is pretty cool. Soooo much to learn. Thank you for taking the time to make this video.

This is great information and pries the lid off a powerful feature.

Awesome design and video . Looking forward to your next steps .thanks for sharing . Terry

The physics joke around 8 minutes was absolutely hilarious!

@8:29 LOL!

toroidal propeller should be called boat propellers without the innards

Practical walk through and thank you for the introduction to the thread workbench. One thing that I would be interested in is your view on the slicer setup for printing threaded items. To avoid support material, flip it on it's top and print that way; great but... This aligns the layer plane perpendicular to the forces when the cap tightens. I have printed a number of threaded items and experienced failures when the layers separate during tightening. I have resorted to printing the parts horizontally so tha the layer plane lines up with tihe forcesj up/down the shaft. This makes the resulatant parts much stronger when the threaded items are tighened but presents other issues like distorted shaft profiles (less thread engagement) and the hassle of cleaning up support material. How do you print so that you can tighten the lid enough to prevent leaking but not snap the top of the lid off? You are counting on pressure against the garket material.

I'm going to have to play with the binder - connect - slice apart workflow. It's capable of some neat stuff as you show

You got it right in this case; but for anyone else, bottles use a buttress thread profile which means they aren't symmetrical and only (properly) thread on in one direction. For bottles the external thread has the slope facing upwards and the flat on the bottom. For a cap it's the opposite, flat(ter) face up.

Very cool, thanks for the accepting the request! Have a merry Christmas

I can tell you're using KDEnlive. So do I. On those many stills you faded in and out of there at the beginning, you can eliminate the background flashing in and out by simply adding a transform effect to the stills and scaling them by 1%, i.e. up to 101%. That eliminates the background around the still.

You deserve more attention. Greatly appriciated tutorial.

Sir, you deserve way more views! Great information about FreeCad, thank you.

Well you lost me, but luckily this will be here when I need it! Man I wish tutorials like this were available when I got my CE.

Nice. :)

Nice tutorial, I learned something new here. Too bad about that "rounding error" issue - that's the kind of thing that will drive a new learner batty. With no understanding of what's happening, they have no tools to diagnose and everything just looks broken.

I'm using RC1 and when I try to attach the sketch at 2:51, I do not have Frenet as an option... Anyone know what's up? I was in the part workbench.

Still runnin' RC2? 1.0 proper has been out for almost two weeks. :P

good teaching style, thank you very much for this video! helps me on my own freecad journey

Can you do a video on making something threaded to thread on an existing object? Simple example would be like taking this knob and making it thread onto a pop bottle.

When I tried this new tool in Freecad 1.0 on three lines, it worked ok. When I tried to make two circles concentric, I received an error 11304. No error on doing the same in Freecad 0.21.

The title is misleading, but it is true. FreeCAD had MITIGATED the issue to make it AS GOOD as other car platforms (most of the time)

I used to break FreeCAD every single time. Now it's substantially more robust and well-behaved, in fact ever since that Realthunder fork. I do wonder which of these is better to use, still the fork or the new FreeCAD 1. I still feel it has a long way to go becoming easier to use. I did sometimes have to just quickly design a replacement part when say repairing a piece of electronics a complex one and doing an effectively non-parametric somewhat broken model was the way to go, i did it back then in that commercial software popular with hobbyists in just a couple hours and having the device repair completed same day was worth it. So i think you want both things, you want the CAD to try to retain parametric quality, and try to just survive through quick and dirty work and allow you to continue while outputting valid geometry, both can be useful. I do like that FreeCAD has some model repair capability where you can just re-parent a sketch and reassemble the operations. Though in the past i have had problems with that as well when operations would not re-assemble cleanly even though they worked before. More disappointingly, i was barred from reporting a bug on the issue tracker, and when reporting on the forum, i wasn't actually necessarily seeking a solution, which yeah good to know, but primarily a permission to report the bug, a yes or no question essentially, and got nowhere with that, was looking for either "it's by design it's not supposed to work" or "please report a bug", not even with me restating the question several times over several pages of discussion did i get a direct statement.

This problem is not really the same as the TNP. And yes any cad program would error out when the elements you are referencing are substantially changed or eliminated! When you saw the leg off a ladder, surprise, it falls over.

- Nice example. Well explained :) - On a side note: though you were joking (haha), it is not the world's worst hammer - "The world's best toothpick makes the world's worst hammer." (Or something like that; and here, too, just joking :D ) - Carry on...

one way to improve this would be to add a popup option menu when performing an action which breaks geometry like this, for example "this action breaks the existing sketch <name>, would you like to 1: copy original surface to attach sketch (default), 2: attach sketch to the nearest surface, 3: manually select a new surface to attach sketch, 4: manually fix sketch(do nothing)".

Very good explanation that the TNP is not really a problem of FreeCAD only, but basically affects every CAD programme. Without mentioning other programmes by name. I like it.

Topological naming problem can not be fully solved. Only mitigated to a certain degree.

There was an effort by some to make the point TNP is endemic and can never be "solved", only mitigated to a tolerable level. Any time the term "solved" or "fixed" was used in print, one or more people would make a point of saying: "no, it is mitigated, not solved". I wish there had been better expectation control.

FreeCAD has been improving every year.

Thanks for this video. I was so confused the last days when I kept reading that FreeCAD had “solved” the TNP.

This is a big deal, might have to look at freecad again, I am dying to get off of Fusion360, and I am willing to pay upwards of $75 a month USD to do so. Also better CAM software would be massive.

Nice explanation and solution.

great video, but the fact that problem can't be solved fully doesn't mean that we can't make it easier to work with. The improvement I am thinking of is to give user choice. I mean, when you do some change that break geometry, there would be selection menu on the side of the program to show user options to choose from. So default behavior could remain intact but application would predict most likely solutions to choose from.

CATIA V5 operates in a very similar manner. If I were building a model intended to handle a lot of parameteic and/or topological change I would be avoiding topological references as much as possible. Most stable - Reference geometry (explicit points,lines,planes), faces, edges, vertexes - least stable.

Very well done, so I subscribed. Thanks.

Great video! I've been using FreeCAD for at least 8 years, although just for periodic hobby projects of varying complexities. I learned a couple new techniques from your video. I wasn't familiar with ruled surfaces. I've probably used the split edge tool, but it's not something that I use often since I usually just know the geometry that I'm planning to draw and construct it line-by-line if it isn't a simple primitive like a square or circle. I've also never come across "inertia mode" for attaching a sketch to a face. I've always attached to the plane and then constrained relative to the x/y/z origin, but I can see how attaching with inertia mode would be a lot easier and more convenient in many cases -- especially when attaching to faces that aren't parallel with the XY, XZ or YZ planes. Otherwise, I fully agree with your commentary on the TNP, and I think the behavior exhibited by FreeCAD in this video is entirely appropriate. In the past, my greatest frustration with TNP issues in FreeCAD was when I had to rework a broken geometry but for some reason FreeCAD could not recompute my model when I tried to reattach sketches to different faces or otherwise rework the order and construction of my part designs without deleting some of the work and doing it from scratch in a different order. Hopefully FreeCAD's ability to reattach sketches to different faces without breaking has improved in 1.0.

2:00 worlds worst hammer 😂
