Showing beautifully how to use CAD Sketcher with recent updates, is the best way not just to make the user experience as gold as possible, but overcome problems as you go.
I've learned so much with this video alone regarding CAD Sketcher.
Signed up for support for this project. Am hoping in time it will have a more integrated and intuitive workflow - this vid demonstrates there is still a long way to go. The support rib for instance could be a dedicated command. But it's certainly a huge step in the right direction for having engineering type constructions in Blender which has been missing for too long.
I really wish in the future there will be a separate "CAD mode" (or sketch mode?) alongside the other modes... this project is insanely great
I understand the desire to appeal to Blender users with a shortcut-based workflow, but the large number of shortcuts, some of which overlap Blender's defaults seems less than ideal. I would much rather see these functions broken out into pie menus or shortcut menus to spare users the memorization (and have the opportunity to add tooltips).
Like a search option like how the brushes are layed out in zbrush kinda
exactly, it needs to be buttons and icons.. just like in CADs
@@chronokoks Nah. user's will get used to it
I hear you. One option would be to add a 'pre-tap' to the shortcut, much like you'd double-click a mouse button. For example, instead of pressing , you'd press . Tapping the modifier key by itself before giving the command would alert the addon that the next keypress would be specifically for it, instead of Blender, itself.
Does that make sense?
@Jorge Zombie how to use the industry standard keymap in Blender ? (and of course how to get it)
thank you i am gehane from egypt, in the begining it took me time until it work but it deserve
Brilliant!
ive only watched to 4:30, but i can already see that its easier with freecad. if you are already a blender user, you might want to continue using blender, but i as a freecad user will not switch :)
Absolutely Great! This is like a dream. One question, is there any way to produce a similar result as the Offset of AutoCad?
I LOVE YOU. THANK YOU
I have CAD SKETCHER 0.27.2 in Blender 3.6.4 and its not working in M2 Pro, the ctrl+shift+a does nothing and there's no way to make a rectangle
Does the topology get messed up when using booleans in cad sketch like it would with regular modeling?
I had issues following the tutorial because constraints misbehaved. Restarting Blender fixed them.
Beware that constrainsts will be desaturated red when okay and saturated red when there is an issue with them. They aren't green like in the video.
Being able to do cad drawings in Blender would be a gift from God.
I use cad sofware but you know comparing the speed on design on blender with cad or precise designs take more time than solidworks fusion360 or autocad maybe someone cand develop a blender subprogram oriented to cad designs engineering and architectural designs
@@jesusveravera9769 the difference between the programs that you said and the blender cad sketcher is that cad sketcher is totally free and open source. I think is a different final user, like me, that have not a ton of money to invest in any kind of paid 3D CAD software only for create some 3D pieces to print at home, while in engineering office where I work Solidworks fits very well and is made for this, I'm a developer not engineer, so CAD Sketcher works pretty well and if I want something I can actually look to the code and change a bit, make macros or change behaviours just like I already did in the office for custom Solidworks exporter for my workmates but took me an entire week to develop. But, have you ever used FreeCAD? At least for my use case it would be a better (and fair) comparison
Rhino is still the best modeler ever and you can draft in it. I can draft faster in autocad, but for being a modeler, Rhino drafting is really good. Then, import the model to blender for the animation and graphics.
This is just what I need... I got Fusion360 but still, I really hate having to use multiple tools for modeling, I guess Blender will soon really be enough for everything!
I would like that too, but still Blender is far away from professional CAD tools like SolidWorks or Fusion 360,
@@marcombo01 indeeed... lets hope for more in the future! Im still using Fusion (Would use Solidworks if it was possible to get for me) too but interested in this project!
There are trade offs to using a plugin vs a dedicated program. But, unless you're suppling finished CAD to manufacturing, I think this seems to totally fill the CAD requirement for most 3d applicaitons
@@BattleGn0me it's not just about being able to creat a model fast Solidworks can run a lot of simulation and studies as well as built in CAM and it comes with a Toolbox that's rlly handy if you are talking big company you also gotta handle files and have auto model creation per excel and stuff like masterfiles Professional Cad like Solidworks and Fusion are rlly tuned for what they are used for and blender just tuned for the creative stuff it's mostly used for
@@BattleGn0me yeah for sure. If I did this professionally currently Id just use a dedicated program, but atm Im mostly making parts for myself to 3D print and possibly sell some times. This would be handy for that.
The day I can replace Fusion360 with Blender for my meager 3d printing tasks, will be a JOYOUS DAY of celebration! 😁👍
Are user parameters planned? So we can easily and simultaneously edit multiple dimensions. Awesome initiative, makes me really excited to not have to use fusion 360 soon.
I'd like something to undercut Fusion so Autodesk is not tempted to remove features again. As open source of course we could choose to add that feature if we wanted. :)
It would be really nice if you could define variables and use them in/as constraints, even better if you could use simple calculations. So variable $width, constraint for object = $width / 2
This is amazing! I had no idea CAD was this far along in Blender. So great!
The CAD precise measurements are definitely better than my work around.
I'll have to give this a try.
Recently I've made a few practical models in Blender, and scaled from the print bed in the slicer, a known measure, to get things to the right sizing.
Getting measurements rather than making fractions in the workflow is a definite time saver.
_I was already familiar with making digital arts, but the main reason I got a printer was to also be able to make things in practical real world applications too._
Quick Question - in your other videos, you mentioned how to set up Blender to do CAD designing... but are you saying that all we have to now do is download the plugin using a default Blender setup and off we go creating CAD models??? Have you made it that more simple????
at 1:07 you say there are shortcuts that are new to cad sketcher and they are linked in the description. Which links are they? None of the links are described as sketcher shortcuts. I tried clicking from "useful links" and down without success. Ever since i installed Sketcher I have been looking for sketcher's shortcuts. Give a sketcher noob a break please
You took almost 30 min to create that modle but modelling this only takes 5min in any cad software like solidworks
I've got a question? Or two...
1. Can you copy sketches from one plane to another. Not reference, but like a copy and paste of the sketch?
2. Can you use some type of global variable as a dimension parameter in sketches?
Even without using icons, buttons or pie menus, it's easy to use than FreeCad. I gave up using FreeCad after know Blender and did'nt even exist Cad Sketcher. Now with this add-on freecad will not leave the versions zero point something. They lost the train.
Plus FreeCAD crashes every 10 mins when doing complex modelling. No-brainer to use blender instead lol.
I'm in no way interested in learning CAD, however... your enthusiasm and your incredible tutorials makes me at least flirt with the idea of learning it. I also think that your championing of Blender to quietly devour any other program's monopoly on CAD software is extremely exciting. While I'm likely not ever going to learn CAD it's great to see your enthusiasm and I've subscribed for that alone. I also learn a few things along the way (like Limited Dissolve in this video for instance). Thanks for making the Blender community awesome. Keep it up! :)
Limited dissolve is same as decimate modifier but in edit mode , and we have weld modifier(merge by distance) in object mode and merge by distance in edit mode
holy damn. this keeps getting better and better
This finally looks promising! I was always a little underwhelmed by your demos of the plugin but this one has brought back my hope for the future of CAD in Blender. Thank you!
I might start using blender instead of FreeCAD
Fantastic ! The constraints are nice and clear. Blender is on its way to CAD !
Hello I could not
(Centre on Origin point)
Can you help
As a design engineer of 28 years in Catia and a Blender nerd I really like this. Good stuff.
you joking, yes?
@@srgv no, why?
I’ve tried it out a bit, and it isn’t as flexible as I’m used to having worked with tools like Autocad and Inventor before, but it’s more than I need for my projects (and way cheaper!) can’t wait to see how this keeps developing!
CAD Sketcher Looks really promising rgt now.
I use solidworks professionally and have a license personally, however this is amazing as a free ware tool to allow users to develop structural 3d models, thank you to everyone behind the development of this software.
Have you ever heard of FreeCAD?
The fact this is free blows my mind lol
Oh my word, I can finally be free of horrible autodesk software! I can be free of windows! Thanks for sharing!
Thx for this tutorial on Blender CAD!
Freaking proper tutorial.
Succinct, quick, and you called out all of the hotkeys you were using.
I came here just looking for how to extrude a circle to a cylinder and accidentally became a CAD master. haha.
Keep on being awesome.
really ingenious. I like this addon a lot. If it improves even more, expensive CAD tools would no longer be necessary for simple constructions.
it doesnt add any cad .... this addon just creates a sketch which u can extrude thats it. no cad in there.
The best
Was very skeptical that this was an ad for a paid plugin, but no this is free and it works.
I understand the large community of blender to prefer a build-in CAD from an extra tool. But on the other hand it has it’s pros to have specialized tools. Honestly I would prefer to see these resources put into FreeCAD instead of creating a competitive solution. A blenderstyle ui for FC would be a good compromise, I think.
I really wonder how you manage to memorize all these shortcuts!
As much as I'd love to see improvements and resource put into FreeCAD, every year or so I throw a few dozen hours into it and always end up back with some other piece of software.
It's not the UI that's the problem either - it's the fundamental workings of the thing. The common forum answers of "oh have you tried doing it this other way" when something simply doesn't work and you get some random useless error or because you're in the wrong workbench is simply infuriating.
FreeCAD needs a proper shakeup of the fundamentals which honestly I don't see happening until other open source software starts biting at its heels.
@@mowcius
Ok, I’m pretty new to FC and CAD. I was frustrated from the restrictions of the personal use license of Fusion 360 and gave FC a try. So I always think, I’m doing wrong when something goes wrong. The number of successful models increased since I switched to the branch of Realthunder.
I never tried Blender. I always didn’t know, what I should do with it. Maybe I should try some day, when CAD in Blender is less experimental.
FreeCAD is absolute hot garbage. Every time I've tried to use it, the part I am designing breaks in some stupid way that requires you to start all over again. Easily the worst piece of FOSS software I've ever had the displeasure of using.
I wish someone would come up with a GOOD FOSS or even just reasonably priced alternative to Inventor/Fusion360/Solidworks etc. All I want is basic drafting capability, to be able to make a decent parametric model with software that doesn't crash all the time or inexplicably break whatever you're working on. I'd be willing to pay good money for that, and I'm sure a lot of other people that own 3D printers and other CNC tools would as well.
I have not enough words to say how this amazing and a game changer
What is the keyboard and mouse overlay software you use?
This looks amazing! The features I'm looking forward to most are spreadsheets to define parameters and filleting!
Mac OS: Due to an ongoing Blender bug apple Metal users need to change their GPU Backend to OpenGL under: edit->preferences->system-> set cycles renderer to none instead of metal.
please pin this
Wonderful video ...... Congratulations to the author.
Once again, all credit to the author of the video and greetings from Zagreb Croatia👏👏👏👏👏👏👍👍👍👍👍👍😊😊😊
Regarding all the keyboard shortcuts; an addon or system that would display frequently-used shortcuts for a given context would really help my learning. Basically for every step of the tutorial you provided, a popover in the lower-left could appear and suggest what your next move might be. I think this could really help lower the learning curve. (Theoretically one could train an AI on input data to generate this, but I bet you could get 90% of the way there with simple heuristics.) e.g.
(when looking at a new document) Ctrl-Shift-A - Add Sketch
(when a tool is selected) Right-click - Cancel tool
(when origin and line are seleced) - Shift-N - Add Midpoint Constraint
(when anything dimensionable is selected) - Alt-D - Add Dimension
I imagine several shortcuts listed for most of these, i just took examples from your video.
PS, I've been following CADSketcher since you started making videos about it! I am *very* reluctantly about to learn Fusion360. Really, really wish there was a great open source CAD tool that started simple and supported complex modeling. Maybe there's a way to build Blender Lite with a focus on CAD? Make it 75% TinkerCad, 25% CADSketcher? I think Thangs should invest in building this, as an open-source project it would grow, and they could then link it into their ecosystem.
Few years back I was daydreaming about CAD type build in Blender. :)
I followed your tutorial step by step. Watched several times pausing it and trying do every single action. It was not easy, but you were perfect ! I did it too .Congratulations. I hope seeing more videos about CAD Sketcher videos more like this
It makes absolutely no sense to not be able to draft in blender. How the f do you build anything??? I'm sticking with autocad and rhino for now. Thanks for the video!
If I want to create a 3d spiral(stairs) using only sketch interface, how I could do this?
3D spirals are actually a bit advanced even in regular CAD programs, so I'm assuming they haven't been added to cad sketcher yet
@@NKCubed You can make a workaround. And set more orthogonal view in the same sketch.
Without native import/export .STEP support in Blender, isn't all of this custom UI work in vain? Or can we export solid body parametric files once we're done? Things like CNC machines rely on curves rather than subdivided faces for their paths :/
Looks promessing i hope this keeps getting better
Cad Sketcher is driving me crazy right now. I want to sketch a simple V-Slot profile, no chamfers or fillets. no fancy circles, nothing. Just horizontal and vertical lines. All sides have their dimensions defined, yet cad sketcher tells me I have 2 degrees of freedom. What the hell that that mean?
Where are they. All sides should have fixed dimensions defined..
Trying to resolve this then gets me a "Redundent contraints", without it even higlighting which ones are.
Screw this whole CAD Bull**** I'm going back to precision modeling.
Amazing add-on, it is so well made and amazing presentation! The videos are top notch.
CAD Sketcher not showing increments less than 1". Have a .25", shows as 0". Another is 1.25", Shows 1". Fix for this? Or did I miss a setting that allows that? FYI they are there, just not displayed. THX
WARNING EXPERIMENTAL whats going on ? have CAD SKETCHER 0,27,2 an Blender 3,6,4...
I'm checking out the sketcher for Blender add-on, in the RUclips demo you click CTRL - (minus) but I don't get the BTOOLS modifier that Jonathan gets do I need to install something else?
I have installed the sketcher (CAD_Sketcher-main_0.25.0). Unfortunately, it is not functioning well. It works only for 3D lines. I am working with Blender 3.4. How to fix it?
Does anyone have information about how Sketcher is doing? The last update was over a year ago. I want to learn Blender, but only if Sketcher is not only working but also actively being further developed, as I want to work with it parametrically. If Sketcher is not undergoing further development, I might consider shifting my focus to something else. Thank you for any insights!
Bool tool and rounding error were the reasons that I switched away from blender early in my 3D modeling career (which is probably good since the stuff I was trying to design lent itself to CAD better anyways). What are the chances that these will get better with development?
The planes XY XZ YZ that are shown in black do not display for me. I tried all GPU settings most say no compatibly GPU found, tried blender 3.5 and 4.01 . Are feature not present due to GPU settings? Thought GPU is just for speed not features on off. Can I hack .py src code to enable stuff ?
Hey Keep Makin, hi Comment-Section! At 27:06 you mention to clean the mesh up. I have a little more complex part, but I see we have the same issues: I dont know how the fudge to remove these weird lines which randomly connect from a point on a nearby edge to a random point in a hole. It splits the faces into weird parts, which makes it impossible to emboss or bevel edges. What can I do to fix this?
This drives me nuts. I've been using CAD and I started technical drawing by hand a million years ago and moving to blender is insane.
"I don't know what size this is"
This seems to be the heart of trying to draw in blender. Make something, then manipulate the size.
In cad
draw a line
pick a start point, specify length and angle, done
move
pick an object, specify a start point, specify distance and angle, done
in blender
do anything, change it later
Excellent walktrough, although nothing can beat OpenSCAD for parts like this.
What am I doing wrong. Every time I add a new sketch, anything I solidified from my prior sketch dissappers. I think it's still there, but it's hidden.
I tried it on my mac, and on my windows 11 machine.
Edit: nvm, found it! I saw you click on visibility, that is what was happening. It was hiding mesh.
awesome video, i have been looking into other cad programs but find it hard to follow along.
this however makes more sense to me, thank you!
I am so confused, how are you connecting the arcs? Only one point will connect to something else, and the other one will just teleport away from where I want it, and then tangent doesn't work, I've been looking over there discord and wiki, but I've found nothing.
Edit: I got it somehow, guess it's just super finicky.
It is really nice how blender is starting to become a viable alternative to so many paid software tools.
Would you like to fix everything Cad Sketcher THEME (add-ons) so edge can see bright any color without too black edge on youtube when everyone are on youtube too. Also you can get download (Screencast Key) to help for deaf people watch your youtube how to tutor about Cad Sketcher.
Please.. Indonesian subtitel sir..
I would have drawn the whole thing in 7 mins using AutoCad 2000 with 3 views. I get that you want to show all of the short cuts but if you spend half the time calling up your "shortcuts" you are still wasting time!?
Hi,
when I design model with a holes, using CAD sketcher in blender , it will give me extra vertices in edit mode, why is that and how I can remove the vertices, also the model in cura give errors. thanks IN advance
C'est une excellente idée d'avoir ajouter ce paramètre à Blender, et je pense qu'à terme, cela pourrait devenir même meilleur que fusion 360 ou autres... Il y a encore beaucoup à faire, alors courage et bonne continuation 🤯👍🤓💣💣💣💣💣
Je pensais la même chose, mais les propositions CAO/FAO/BIM sont différentes, par exemple dans Fusion 360 vous pouvez générer une liste de matériaux, dans Revit vous pouvez générer tout un système complexe de suivi de projet et d'ingénierie et lister tout ce qui sera nécessaire pour le construction civile du projet.
So Blender boolean modifier plays nicer with coincident planes now? I remember having weird issues with booleans when two surfaces intersect one another
it looks like he's still getting issues with it as we saw at the end, although there's still work arounds. I'm also wondering about this though
I’m sorry but Blender has no business messing with dimensional modeling. Software like Inventor is an order of magnitude better for this type of modeling, while if you have anything organic, Blender is an order of magnitude better than inventor. I’m not saying this distinction is necessary, it’s just how it is now. Inventor is for engineers while blender is for designers. Both very important but very different
Please consider slowing the pace down and adding some pauses between actions. Having to stop and rewind the video every 2 seconds is frustrating. I'm sure there are others that were fine with it, but I have to quit at the 4 minute mark. :(
I feel like we need to do this right, we'll really need solid modeling operations and not just mesh conversions -> modifiers.
The solid modeling is the easy part tho, up on and on.
Bang mau tanya,,klo sketchup bisa menghitung rab skalian nda ya. Utamanya di ipad
@8:21 - when I leave back_plate, the holes are the filled mesh, but not what you have. I also show 4 degrees of freedom.
Given too many hours of my time for this to be useful. Tried to use outlets available with no results except an offer to but something else. As soon as I check the box to initialize in blender a PY error is displayed. Feel free to contact me if you would be willing to help get the feature rolling and in a operational state so I can vet it properly
waiting assembly feature similar to solidwork ,,good work..cad sketcher
This appears to be a *very* promising tool and I'm grateful to the developers. Will absolutely consider paying for it (once I start using it). One key feature-or set of features-to implement is the use of variables and mathematical formulas. You could support typing in math formulas directly into the value fields (but such that they persist when you want to edit them). Alternatively, if you had some way to create an input and output tree using math nodes, you could set the main parametric inputs (obviously to be determined by the user but examples of inputs you might want to use include things like "scale", "width", or "tolerance"), and then use math nodes to generate a bunch of outputs linked to the value fields in your sketch.
When I work in a new sketch the first one is not visible. When I leave the second sketch, all the sketches are back visible. Could you help me please?
I have a drawing with 1 degree of freedom left. How the hell do you find it? There's zero indication.
Imagine if you could export it as a .Step or similar CAD formats and had design history. Now that would be truly revolutionary
Congrats, you've invented FreeCAD/Fusion
hello there! I try to do the first object follow step by step but when I solidify it is not show the holes in it. the sketch is "fully defined" I try to put more holes in it and it is not happening ? is it some setting for that somewhere? many thanks!
Im not an expert on cad and by watching how you modeled it, its too complicated for me compared to fusion360
my weld isn't working. i duplicated and applied all but nothing stuck to the object
Damn is that a Northern Irish accent with hints of English or am i going mad? Could be Scottish actually
Blender is really powerful but I damn hate the amount of shortcuts it has
I really don’t like shortcuts. Some love them, but I need to see the physical buttons
Having done a small bit of SolidWorks, I'm extraordinarily excited to see CAD Sketcher, as I'd love to use Blender for anything and everything. I donated a bit when I grabbed it and I think I might donate more on another update. Great work!
Very interesting. I followed along and got the same result. Using the buttons made more sense to me than shortcuts, as I understood better what was happening. Was able to export the model directly without duplicating and got zero errors in prusaslicer 2.4.2. I'm mainly a OpenSCAD user for 3D printing CAD work, but this is very, very intriguing!
Thinking about it, global variables (via drivers?) and cross sketch constraints is kind of the only thing that would make me miss OpenSCAD.
Great just make slower and repeat ... im just start and want to invest in it !!!!!!!!!!!!!!!!
amazing stuff
hey i tried to install CAD in blender it doesnt install the PIP even when i have restarted my blender. What do I do? :(
As a solid works user the interface feels off, hope they improve it soon, this has lots of potential for people into DIY.
for me as a near beginner, this is amongst the few best tutorial vids i've ever watched, it's so clean and dense.
really nice tutorial, auto subscribe !
