da hell i barely can make a cube in freeCad HAHAHAHA Started using freedcad last year when i got a 3d printer for christmas and i'm still struggling. You are a monster!!
I will look at "alibre". If it manages to not take the top spot for worst UI in modern software aware from freecad, I might use it. Seriously, the developers must understand context and modality in order to write the software, which is functionally great in execution, can they not by analogy not apply it use? For us?
I have Alibre Design but one limitation it has is that it cannot easily produce physical threads. I really need this for 3D printing. Fusion 360 has this feature. I’m not sure if Free CAD has it or not. This is probably the only feature that I wish Alibre would copy from Fusion 360 as they do it very well.
It's a good point. I have not tried threaded holes, I know Expert and Pro are listed to have automatic threads here in the detailed comparison view: www.alibre.com/alibre-design-feature-comparison/ But I have not yet investigated the extent of that feature. Check out the fasteners workbench on FreeCAD. I usually generate the fastener with the thread I want, then boolean the fastener to create the thread on my model. Alibre could do that with mcmaster carr models of fasteners too. There is another feature that I believe is newer in FreeCAD that my partner @allvisuals4u has covered here that should do what you want: ua-cam.com/video/hXkNqsATWcs/v-deo.html Usually when I print I either tap the thread or use self tapping fasteners if that makes life easier for you. Something like this that uses a hole to tap itself into: www.mcmaster.com/self-tapping/for-use-in~plastic/stainless-steel-torx-rounded-head-thread-forming-screws-for-plastic/ This is a very worthy question that I wish had better answers
@@JokoEngineeringhelp They are cosmetic threads in Alibre. Fusion 360 has a toggle that switches the cosmetic threads to physical threads just by selecting the option. Alibre doesn’t have this yet. I posted a feature request in the Alibre forum once, but people wanted to argue about how useful the feature is. Many designs like the Voron V0.1 3D Printer is made using 3D printed parts such as belt tensioners with plastic threads and plastic nuts. I don’t understand why people would argue to keep a limitation in this product. I can understand why you wouldn’t print a 2mm threaded bolt. That wouldn’t make sense with todays 3D printer technology, but a 20mm part with a coarse thread works very well on a 3D printed part.
Not an expert on FreeCAD by any means but short answer is YES. Just do a UA-cam search for Freecad threads. LOADS of tutorials. Just ensure you use the latest stable release for production use (0.19.3) or 0.20.0 Beta but seems pretty stable. Details correct at 22/2/2022.
How do you fix the topology naming errors? I noticed that things break specifically when making reference to external geometry. Are you supposed to go back and redraw the broken sketch every time you make a change?
Although this was made in SolidWorks, the principles apply to all the other platforms. ua-cam.com/video/mbLsBjZtoTk/v-deo.html Generally yes, broken references should be corrected to the right geometry.
I taught myself VBA but that was the extent of what I know of programming. I'd like to jump more in to it but I haven't had a chance. In your experience, does OpenScad have similar capability in model generation to FreeCAD or Alibre or would you prefer the programming interface or both/neither?
@@JokoEngineeringhelp One thing is it is slow to render. It is basically a very simple but powerful scripting language. You can make reusable functions and there are many free libraries out there for it. But i think i am biased because i do programming for a living and right now it is easier for me than CAD. I suspect if i learned a good CAD program, I would prefer it. I tried FREECAD but i hate it. It crashes and I find simple things hard to get working. Been thinking of Alibre.

@@3dprintingfun329 Relatable! Much respect for those who program for a living, it's a great profession and requires good logic. Alibre has a free trial if you haven't tried it out yet. Since I'm coming in from the mechanical side, I rely a lot on the graphics display to 'spacially' visualize everything; naturally I gravitated more to FreeCAD, Alibre and SolidWorks. Good luck!
Thank you for introducing me to OpenScad. I am new to CAD, and have been using FreeCAD. At first, I HATED the software, because it presents a large number of options, but requires specific things be done in particular ways to use them. This is unintuitive and requires "learing" the interface. But it has grown on me immensely, and for many tasks it is easy to see "how" they can be done. One thing that I like about FreeCAD is the infrequently mentioned Addon system. It is IMMENSELY powerful, adding things like node based "programming" to the software, as well as the ability to model 3D curves from a set of disjoined splines. FreeCAD's spreadsheet is also very useful, allowing for some associative paramerization control over values that can then be presented in the CAD model. But sometimes, programming is wanted (by me, at least) for complex parameterization. I was actually thinking of writing my own "CAD" software for precisely this purpose. But I think I'm going to look at OpenSCAD first, after my exploration into OSC is complete.

Good question. All my videos default to Atom, I occasionally will use Alibre Design but the thumbnail is specifically marked with 'Pro License." Everything in this video is Atom. You can have a long list of Alibre Version differences here: www.alibre.com/alibre-design-feature-comparison/ ^change the list to detailed comparison to see all the feature differences. The major points for me are the pro licences have some time savers like more ways to draw arcs, (these don't limit your capabilities), Pro has sheet metal, boolean capability, proprietary file format support (like SolidWorks .sldprt) GDT callouts in drawings, and I think a few extra assembly tools. In my opinion it's stuff that you really don't feel too hard unless your working in a manufacturing environment.

No price on the website. Buy only through retailers. File Formats: "Broad Range". Did we just step back in time to 1998? Just because of that alone it's not an option.
www.alibre.com/atom3d-import-export/ This page from Alibre.com lists Import proprietary formats from SolidWorks and neutral formats as STEP, SAT, DWG, DXF, while Export Formats are 2D and 3D PDF, STL, STEP, SAT, DWG and DXF. Are you outside the US? Price is listed for US IP addresses on the website but uses quotes outside to my understanding. SolidWorks/3D Experience/Catia, Creo, Ascon Kompas and others require a quote to provide pricing for the majority of their license options often through resellers; many providers sell that way. I'm not sure how import/export formats or quoting makes Alibre not an option.

Hi Marvin! History trees are needed for engineering. While the model shows the finished product, history trees show every step and every parameter used to make the model. This is not useful in modeling for things like animation usually. For instance, lets say I have a feature I need to change by 0.05mm, and I have 20 items that dimensionally depend on the feature I need to change. Without a history tree, I have to change everything With a history tree, I can revisit the original dimensions that I gave the part, and If I modeled with correct intent, the 20 dependent items will automatically update based on the one dimensional change. In something like animation, it probably doesn't matter to update things here and there, but for engineers who need to track every dimension of every feature on every surface, it really helps to have the parametric 'history tree' system for easy updates, being able to scrutinize every step of making the part, and setting relationships between features that update in dimensionally predictable ways that mean less work. I understand your point of view because I approached blender wondering how anyone would want to model without a history tree. But then I started seeing the cool benefits that Blender and other modelers offer. It feels like different worlds, but both ways are awesome. Hope that helps.
@@JokoEngineeringhelp Yeah, I don't do animation. I've been doing "engineering" in CAD since the 80s, and that's why I don't get the history. We never needed it. In fact, I have done just about every thing you can use CAD for, [surveying, petroleum assay, jewelry making, engine building, stress and flow, optics] and I have never said, DAMN, I wish I could go back and undo something?? There's no back, it's always forward. It has literally never been an issue for me, and I am really trying to figure out what it is that I do now, when I need to change "20 items" See, I would just select the "20 items" and then go to the dimension panel and change the dimension for them en masse. History sounds like the exact same thing, but with more steps. I cannot understand why you wouldn't either select handles and snap them to a new point, type in a new dimension, or hit scale? Nobody has ever really given me a CLEAR situation that a history would allow you to modify something quicker or better than just modifying what you need modified, directly. I think when you're used to working in the real world, building solids on a computer, you have a different workflow that is time agnostic. You make things much more flexibly that way. If I decide I need to "go a different way"... well actually, right.... My newest project, I saw a sample of a different methodology on the attachment point. So now I need to change 1/3rd of my model. I am going to make the new piece and swap out my old piece with it. What does history do for me here? What if I made that piece first "in history"? What if I don't want it to push an update through history because I want to see how the new method integrates? Here is a good example in an old quote: *“The sculpture is already complete within the marble block, before I start my work. It is already there, I just have to chisel away the superfluous material.” - Michelangelo Buonarroti* See, engineers, since we're not magicians, we start with things that exist and remove from it, to make what we want. That's how we CAD.

For instance, lets say I have a feature I need to change by 0.05mm, and I have 20 items that dimensionally depend on the feature I need to change. Without a history tree, I have to change everything With a history tree, I can revisit the original dimensions that I gave the part, and If I modeled with correct intent, the 20 dependent items will automatically update based on the one dimensional change. In something like animation, it probably doesn't matter to update things here and there, but for engineers who need to track every dimension of every feature on every surface, it really helps to have the parametric 'history tree' system for easy updates, being able to scrutinize every step of making the part, and setting relationships between features that update in dimensionally predictable ways that mean less work.
I understand your point of view because I approached blender wondering how anyone would want to model without a history tree. But then I started seeing the cool benefits that Blender and other modelers offer. It feels like different worlds, but both ways are awesome. Hope that helps.
@@JokoEngineeringhelp Yeah, I don't do animation. I've been doing "engineering" in CAD since the 80s, and that's why I don't get the history. We never needed it.
In fact, I have done just about every thing you can use CAD for, [surveying, petroleum assay, jewelry making, engine building, stress and flow, optics] and I have never said, DAMN, I wish I could go back and undo something?? There's no back, it's always forward.
It has literally never been an issue for me, and I am really trying to figure out what it is that I do now, when I need to change "20 items"
See, I would just select the "20 items" and then go to the dimension panel and change the dimension for them en masse. History sounds like the exact same thing, but with more steps.
I cannot understand why you wouldn't either select handles and snap them to a new point, type in a new dimension, or hit scale?
Nobody has ever really given me a CLEAR situation that a history would allow you to modify something quicker or better than just modifying what you need modified, directly.
I think when you're used to working in the real world, building solids on a computer, you have a different workflow that is time agnostic. You make things much more flexibly that way.
If I decide I need to "go a different way"... well actually, right.... My newest project, I saw a sample of a different methodology on the attachment point.
So now I need to change 1/3rd of my model. I am going to make the new piece and swap out my old piece with it.
What does history do for me here? What if I made that piece first "in history"? What if I don't want it to push an update through history because I want to see how the new method integrates?
Here is a good example in an old quote:
*“The sculpture is already complete within the marble block, before I start my work. It is already there, I just have to chisel away the superfluous material.” - Michelangelo Buonarroti*
See, engineers, since we're not magicians, we start with things that exist and remove from it, to make what we want. That's how we CAD.
@@m4rvinmartian What platforms have you used?
@@JokoEngineeringhelp this answer should be an entire video by itself.
@@Z-add In a month or two, I'll be covering non-parametric 3d modeling and it should be a good contrast to see the differences
Pc specs?
Not used anything MS for over 20 years, and don't intend making such a retrograde step EVER, so won't ever be using Alibre either.
