All about ensuring your design intent is captured, the models are maintainable and will update successfully with parametric changes. It has a lot of what we like about OpenSCAD the ability to quickly and easily specify two 5 mm holes exactly 21 mm from each other, center-to-center and then change that distance easily. Change one of the link values and watch how the movement of the mechanism changes. I am aware of one open NURBS issue that is an actual regression where the model works in version 2.3 but not 3.0. you might use something like assembly4 plugin as well. You can also simulate your model, as you build it and tweak various parameters to get the desired action in your gadget. I don't think the problem is really the ID list implementation, but algorithms with O(n*2) time complexity. This file is linked to the Solvespace file and the variables can then be used in a sketch (also possible to do math with variables). In fact, FreeCAD's incessant crashing (and the fact that it corrupted the savefile when doing that) was the single biggest reason I put so much time into improving SolveSpace, although working assembly support is a close second. SolveSpace is interactive-oriented (similar to most CAD programs) whereas OSCAD is code-oriented. My way in was though the NURBS code which hadn't been touched in 2 or 3 years when I found it. Forum threads: Understanding the source code big picture (Tue Nov 1 2022, 14:55:43, 4 replies) Automatically create constraints for dxf import (Wed Oct 26 2022, 14:10:33, 6 replies) I'll definitely try this for my next design. And it has the potential to do so much other really cool stuff. 6MB installer free .exe, oldschool. But it is not designed well for engineering and cad. There are vague plans for integrating Lua in a way that lets people implement new constraints without touching the C++ code, but the current architecture makes it very hard. Applications include: modeling 3d parts - draw with extrudes, revolves, and Boolean (union/difference) operations modeling 2d parts - draw the part as a single section, and export DXF, PDF, SVG; use 3d assembly to verify The project seems much more secure as a result, while development remains slow but steady ;-). Minimize the property browser using the small up-arrow at the upper right-hand corner of the window. no fillets or chamfers), FreeCAD - very powerful but almost unusably buggy (others seem to have had better experiences), OpenSCAD - very powerful but requires coding for everything, Then there are various non-3D cad tools and a few online ones (of which I've got the most use out of TinkerCAD which is easy to use because it is very limited in its capabilities). Forum Contact. > My brain hurts from how it goes against all programming principles about DNRY, modularity, and composability. Collaborating with Internal Dev Experience and Tool Teams, Latest Enhancements to HashiCorp Terraform and Terraform Cloud, Sternum Adds Observability to the Internet of Things, Physical Computing Types See GitHub a Little Differently, Intels Open Source AI Toolkits Targeted at Verticals, Google Puts Open Source in Chip Design and Manufacturing, ARM Server Chips Get a Boost with Amperes Altra, Burning Man Returns with a Quest for Sustainability, Meaning. OpenSCAD is great, but sometimes I just want to fidget around with an object like in this SolveSpace demo video. Functions can't draw anything but can return values. Community. Look at OnShape. Not even calculate bounding box which can come handy if you want to place something on top of your model etc.. Love this piece of software! sudo add-apt-repository ppa:alex-p/solvespace. There is also solvespace-cli which is built along with it. If you like the thought of the scripting power OpenSCAD gives you, but like the convenience of a GUI at times, the cadquery plugin for FreeCAD may be worth a look. We also use software tools like programming languages, Linux, interactive development environments (Arduino IDE) and various niche desktop applications. Modules can draw but can't return anything. I use 'master' builds since SolveSpace became open-source. Depending on what someone is doing guess they're complementary? Learn more I found that anything even remotely complex using OpenSCAD brings the machine down to a crawl. For this model to behave like a four-bar linkage, we need to add some constraints. Sovereignty, as in control, independence, no interference, added clutter by youtube? Ramez: News ; Hacker News - SolveSpace - open-source parametric 3D CAD tool Order USENET access 5 backbones 1 server! Amazing system. SolveSpace has a lot of constraints & this is a key feature of SolveSpace. That strikes me as being very similar to the Part Design Workbench of FreeCAD which uses the Sketcher and constraint solver. I tried a few other free CAD programs before and this is one my favorite. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. I've been using this software quite extensively to design a small 25m2 house I'm building earlier this year. The Hacker News is the most trusted independent news service focused on publishing breaking news and high quality articles on cyber security, hacking, information security, computer security, cybercrime, ethical hacking and technology. I would love to see some significant sponsorship of SolveSpace, there is enormous potential for a modern and useable Parametric Kernel. SolidWorks, Onshape, Ansys, Abaqus etc. Unfortunately, the example Ryan provided is closed-source. > This feels like a terminal based 3d application, From my point of view, the default color palette give a very strong impression of that feel. >> This feels like a terminal based 3d application, and I love it! Download. Source code for the first release is available for download at: solvespace-rel2..zip; Later versions of the source code are hosted in git at GitHub. Otherwise, keep up the great work. True SolveSpace and FreeCAD can't do this, however all professional CAD packages can and it's an important feature of them. Now you mention it it does remind me vaguely of Tektronix and VT320 interactions with applications on a Vax in my university days! Ideanote is the #1 rated Idea Management solution for companies of all sizes. I'll give solvespace a shot to see how it compares, for me the reason to use parametric CAD is that I'm far more comfortable programming something than editing it in a GUI, and besides it makes changing stuff so much easier. He's an Excel fan and an engineer seemed to work quite well. This is by far my favorite CAD program for quick engineering-oriented designs. Of course then you' have to source measurements etc. SOLVESPACE is a parametric 3D CAD program with extrude, revolve, union and difference functions. A rough summary is that overall I think FreeCAD is more powerful but SolveSpace is more fun. He even found a builder who uses the pro version of the software (Chief Architect) so my father could view / tweak the model. Can Observability Platforms Prevail over Legacy APM? Synap is an award-winning exam platform that empowers organisations to deliver secure, online exams with ease. Version 2.1 and onward runs on Windows, Linux and macOS. Otherwise its a bit less flexible e.g. Would be interested only if/when some sort of iLogic-like implementation is present. SOLVESPACE-- parametric 2d/3d CAD. Get comfortable with the program and I think youll find useful ways to save time by simulating your mechanisms, before you cut, drill and assemble that initial working prototype. Does it get as bad as OpenSCAD? My dad essentially "designed" 2 houses using nothing but Excel with square cells. Havent tried the newer paid versions. Could you provide a bit more detail about this? It's really good. Collect, develop and manage more of the right ideas from customers and employees to drive your growth. Perl 5 7 4 1 Updated on Jul 12. libdxfrw Public. leoedin on Oct 6, 2016 [-] Also export STEP files for other CAD/CAM applications. You should really give Solvespace 3.x a shot it's come a long way and a lot of performance issues have been solved. Pretty easy for an amateur/hobbyist to learn, powerful enough that your architect might use it, too. I like it because it is bare-bones and you dont need to learn a bunch of extra graphics-related topics, just to see how your designs might work. http://www.freecadweb.org/wiki/index.php?title=Basic_Part_De IMO the main issue is that the constraint solver recomputes everything whenever you add/move something, even though past additions are already properly constrained. And I'm on an overclocked 5930K with 64GB ram ;-). Hedley four-bar linkage with the pivot and jaw extension. Tutorials. We need your input! Applications include modeling 3d parts draw with extrudes, revolves, and Boolean (union / difference) operations modeling 2d parts draw the part as a single section, and export DXF, PDF, SVG; use 3d assembly to verify fit You can highlight the dimensions and drag them around to make the model less cluttered and easier to read. Great for small teams. Freecad has such a myriad of options and controls that I find myself often taking a while to find the one I'm looking for. >The workflow seems to be heavily constraint based. Collect, develop and manage more of the right ideas from customers and employees to drive your growth. yourself and there's no helper features, so some of these other suggestions look quite good. What "missing constraints" you talking about? A plain text file is used to list all the variables and their values. The is a python API for it's constraints solver: This feels like a terminal based 3d application, and I love it! SketchUp is probably a good option for your use case, although I've never used it (or any other CAD). Repositories. The performance gain was huge though. Give your customers the answers they want; quicker than ever before with GoDesk. >> but it was open source so I was able to extend the code and contribute a feature after 8 years of weekly use. https://github.com/solvespace/solvespace/issues/430#issuecom Ended up liking it enough that my father decided to use it to design the home he wants to build. I'm still learning how all the pieces of the code fit together. When modelling with parametric CAD you are not only designing the object, you are designing a cad model that represents the design intent in an elegant and maintainable way. In particular, a significant fraction of all constraints in a CAD system like that are of the form "the distance between these two points must equal x", which is a not linear in any of the positions, 2d geometric constraints solvers are usually based on BFGS algorithm (. SolveSpace Awards Our Awards and Recognition But what is available works almost without any problems (except for 3D constraints and occasional problems with difference operations on curved surfaces) and is soo fun to use. Well confine our discussion to 2D this time. The program will start with a blank construction display screen. In SolidWorks they are called "configurations" and can be driven by an excel spreadsheet, you can literally create thousands of variations from a single model. What Is Supply Chain Security and How Does It Work? I'm a software engineer with no background in civil engineering / related fields. (cut from sheet aluminium https://github.com/buserror/buserror-reprap/blob/master/stl/). Keep at it! Im still stuck at the last free version 2017 make. Its a real shame most of these cad-like stuff are going subscription only. Easily remediate IT issues, automate common tasks, and support end-users with powerful IT management tools. We haven't used it as much, though, and FreeCAD integrates nicely with OpenSCAD which we use a lot, too. what does FreeCAD lack compared to this? Version 3.1 incorporates Eigen for matrix operations in the solver - another old contribution by Alexey Egorov that we finally merged. If these are linear constraints, maybe they can use the "Cassowary" incremental solver. That looks interesting -- especially the path generator, as most CAM software are non-free and all clunky.. SolveSpace is by far the most interesting thing happening in open source 3D parametric CAD, specifically because they have built their own advanced parametric CAD kernel and constraint solver. sudo apt-get update Do the installation. The design is a bit crude, but the goal was to get the structure's dimensions right. SolveSpace is quite fantastic as a technical achievement, but it's rather limited in terms of CAD. I have not used both apps extensively, but clearly FreeCAD is much bigger tool with wider use-cases. It is fully DRY if you learn how to use it properly. Although apparently(?) Over time, the nature of Whitequark's work with SolveSpace has evolved, even as it has taught her the importance of going slowly with code improvements so as to maintain backward compatibility. We aim to avoid introducing bugs. They're solved by a Newton-ish method, which for underconstrained sketches also minimizes at each step the sum of the squares of the distances that any un-dragged points move (plus some other stuff). Do the same highlight and Constrain/Distance process for the other three links. M-Labs contributed to its development around 2015-2018. Yes. I wrote an earlier solver that did this in some cases, but SolveSpace doesn't at all. It can be a bit rough around the edges, but it's already quite usable and powerful! That ID list change never made it in and AFAICT it isn't known to be complete. CadQuery is damn near impossible to install without ruining your system (drags in the whole ffing conda ecosystem). SolveSpace's precision, constraints, and great keyboard user interface make it a fun program to design parts in. Most recent update June 2 2022. https://peertube.linuxrocks.online/video-channels/homehack/videos, https://news.ycombinator.com/item?id=27772183, https://peertube.linuxrocks.online/w/p/aHLbti8HawmE69nBaKPGj1. In this video I follow an AutoCAD challenge.SolveSpace is a free and open source, fully parametric . Current Solvespace maintainer here if you have questions on that. Next, run apt-get with the update option to make sure all the repositories are current. SOLVESPACE is a free (GPLv3) parametric 3d CAD tool. Move the cursor up vertically about 1/2 inches and left-click the second point. But when you're drafting machine parts/machines you rarely need true 3D and that's what I'm using it for. Contact him for consultation, speaking appearances and commissioned projects at doc@drtorq.com or 407-718-3274. OpenSCAD is also very annoying in the sense that it doesn't allow you to "probe" your model to construct it further: it has exactly zero self-introspection features. If talking about 3D cad only, I like minimalist Solvespace's approach better (from UI/UX stand point and from source code's perspective as well), easier menus, easier use (simple shortcuts), readable and rather small-ish codebase. I used to use Inventor professionally, and that had a MTBF of perhaps 4 hours. Examples. It is among the best open source tools out there.". "Currently, the focus of development is to improve SolveSpace's handling of complex assemblies with many similar parts by allowing to load a hierarchy of sketches instead of a single sketch and propagate the changes as they are made, and to derive many variants of geometry from a single sketch. Technology. The right upper point should move in unison with the left point. The only other "advanced" open source kernel is Open Cascade which is a little difficult to work with, and nowhere near the commercial Parasolid in its functionality and accessibility. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. An Introduction to SolveSpace By Marcus Rockcliffe on June 21st, 2015 in Software Tags: cad, design I was recently made aware of a free modelling tool called SolveSpace. It's great for simple designs or just messing around, though, I'm very impressed. reality: https://goo.gl/photos/Gn66MSc8UPshR3CC8. That should speed up successive renders quite a bit. * * * SolveSpace is free software, distributed under the GPLv3. There are ways to do this in FreeCAD. Is VMwares Carvel Donation Just Another CNCF Sandbox? Official release binary packages for macOS (>=10.6 64-bit) and Windows (>=Vista 32-bit) are available via GitHub releases.These packages are automatically built by the . At the command line, first add the SolveSpace repository to the apt software repository list. Version 2.1 onward runs on Windows, Linux, and macOS. edit: dang, got ninja'd by one of the devs in the cited threads! Four-bars are useful to translate motion, increase/decrease leverage or keeping a couple of links parallel. The ideal on-premise or cloud based email support tool for startups and SMEs. This program helps you model your mechanisms and see if your design operates as envisioned. NinjaOne provides remote monitoring and management software that combines powerful functionality with a fast, modern UI. Installation Via official binary packages. Now I want to learn if there are any code-based constraint-based CAD packages. Our software is fast, it's accurate, and we offer expert help with the tough stuff (so there's less for you to do). Strikes me as different than something more drafting oriented like Freecad. I came across the cadsketcher via Maker Tales and can recommend his youtube channel for anyone new to Blender just trying to make it work for CAD. Compare Business Cloud Essentials VS FreeCAD and find out what's different, what people are saying, and what are their alternatives I'd love to be wrong about this, because this general problem is one I'd be very interested in being able to solve more efficiently. ie- Curve and polygon design. I couldn't even figure out from the reference manual how to generate an input file programmatically. Installing SolveSpace on a Linux notebook is straightforward. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. give me a second face parallel with XY from this point in direction of +Z. SolveSpace is by far the most interesting thing happening in open source 3D parametric CAD, specifically because they have built their own advanced parametric CAD kernel and . Interiors VS FreeCAD Compare Interiors VS FreeCAD and see what are their differences
