I understand you made this video as an example of how to use the mixed curve tool -- but just to further my own understanding -- couldn't you have accomplished the same thing with a boolean cut? That was my natural go-to when I understood what you wanted out of the end result. What would be the advantages/disadvantages between the two approaches? Is one more parametric than the other?

Hello, I will try to speack english 🙂.... Thank you for this tutorial. I did it and I print (with little modification). I add the name of my daughter in the bottom of the box. I'm looking to add a "clip" system, because the box could open (if you put the box in a handbag). At moment it's to difficult for me. Maybe an idea for a next tutorial. Thanks

Great tutorial, I'm jotting down several notes for future reference. A sticking point at 7:55, when I ctrl select the cylinder, placement, and join in that order and then select Moved object, it does not nest in the Model pane like yours does. It creates the moved cylinder underneath cylinder, join, and placement. I've had this same problem in other Lattice2 tutorials. Any advice is appreciated. I'm using Freecad v1.0 and Lattice2 v1.0.

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.

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.

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.
@4axisprintingАй бұрын
Having the layer plane perpendicular to the threading would be stronger, but I haven't had much issue with that. I print mostly practical prints in PETG, so I print on the hotter end of the range. For this, I used a steel nozzle (because I need it for some of my other prints and changing it is a pain) at 255°C for the first layer and the rest at 250°C. Bed at 70°C. The extra heat likely gives strong layer adhesion.

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.
@4axisprintingАй бұрын
Yes, the bottle profile tool creates that particular buttress thread. The other Buttress thread tool creates a slightly different rgread. Of course, the V thread tool creates a thread found in things like machine bolts.

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.

Actually, I'm using Shotcut, but it and KDEnlive both use MLT under the hood. I'll try your workaround, it may apply to Shotcut as well.

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.

Prior to the mitigations, the cylinder would have ended up stuck to whatever random face got numbered as Face3 and no error flagged. Part of the mitigation is detecting that that is very unlikely to be helpful or anything like what the user wanted.

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)".

There was an effort by some to make the point TNP is endemic and can never be "solved", only mitigated to a tolerable level.
