Nice references! The output resolution as such can be made "arbitrarily" precise if the model geometry is authored within AdaShape. So the facets in your image would not result from the limitation of the generated mesh (https://www.cnccookbook.com/wp-content/uploads/2017/08/facet...). There resolution is currently fixed to presets for usability (see p. 28 of the changelog for the tolerance values - https://github.com/AdaShape/adashape-open-testing/releases/d...). I did not have CAM/CNC expert to consult on the details so those may be out of whack (but I'm happy to adjust them or add a user configuration). "if it's a good fit, maybe I can take the manual off your hands?" Would redistribution under CC BY 4.0 suit you?

In Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11

As a person who has crashed and burned with every. single. traditional 3D CAD tool (the only things I've been successful w/ are programmatic, so OpenSCAD and its ilk), this is _very_ interesting to me. I am esp. grateful for: https://github.com/AdaShape/adashape-open-testing/releases/d... (given that I shelled out for the _FreeCAD Beginner's Handbook_ 'cause it had Version 1.1 prominently on the cover but the instructions have one download "v1.0 or later" and all the screen grabs are for 1.0 and the wiki is replete with pages tagged "This page needs to be updated for 1.1" or words to that effect). I've been working on documenting a 2D program (for my employer and as part of a side project): https://willadams.gitbook.io/design-into-3d/2d-drawing and if this is a good fit, will gladly pitch in using this for 3D.

Show HN: AdaShape-3D modeler for intuitive 3D printing parts / Windows 11

I've spent the last years obsessed with a sideproject to build a humanistic 3D modeler for desktop. By humanistic I mean a tool that stays out of your way, instead of requiring the user to learn both a complex UX surface as well as a complex theoretical basis before being able to model effectively. The GUI is uncrowded and the modeling affordances are only those which are intuitive to present to the user. Which is sort of backwards compared to most CAD packages where the technical complexity takes the front stage. Here the hierarchy is intentionally reversed. This is still in alpha-stage, but the features are mature enough for feedback and experimentation. TinkerCAD is actually what comes philosophically closest to this, but it's hobbled either by Autodesk's strategy or by technical limitation to be a really good tool beyond certain comp

lexity. The ambition here eventually is to provide a tool that has same intuitive capability as building Lego bricks, while not compromising on engineering qualities. The main intent is to make extrusion based modeling operations super easy, to offer robust STL and STEP import and allow complex modeling via boolean operations. The modeling logic is parametric and volume based - the surface presentation is always a discretized water tight triangle mesh. This is the clearest philosophical differentiator to traditional CAD/CAM packages - or visual editors like Blender. Rather than force the user to nurse surface topology at every stage, the modeler will only permit those operations that result in a correct output. This is not an SDF (signed distance field) modeler. The domain model is fully based on parametric analytic shapes. This means the tessellation is crisp and specific. The modeling data is immutable and serialized to disk while modeling. For the user this gives a perfect undo and zero data loss. It's built for efficiency first - my test workhorse is a Thinkpad T14 Gen 2 i5 with an integrated gpu. It's not supposed to be a replacement for complex surface design tools like Fusion 360 or sculpting software like Nomad Sculpt or Z Brush. You can find a review of current features in the youtube playlist linked below [0] and the link to the latest alpha 0.1.7 download from the homepage [1]. The test binary is provided via github release [2] but this is not an open source project. I know some people hate videos over reading and I'm one of you but I don't really have bandwidth to both develop features and write good instruction copy.

"I do find the graphical interface very natural for doing creative design work" As do I! I don't think there is any correct single answer. People, their workflows, and requirements are different. It seems we are living in CAD renaissance which is great! So many new promising new companies and free tools popping up. Personally I would prioritize data stability and visual accessibility. These give user a creative workspace that is intuitive and forgiving. That's why I started doing my own modeler as a side project: https://github.com/AdaShape/adashape-open-testing/releases/t... The data model is fully immutable and would enable doing _proper_ model branching when I get there. For now all the user gets is a super robust undo and not needing to save (the model is streamed to disk persistently). But eventually I would like it to be a visual, r

"So why do you think a 10 kLoC vibecoded codebase will be any good engineering-wise?" I've been coding a side-project for a year with full LLM assistance (the project is quite a bit older than that). Basically I spent over a decade developing CAD software at Trimble and now have pivoted to a different role and different company. So like an addict, I of course wanted to continue developing CAD technology. I pretty much know how CAD software is supposed to work. But it's _a lot of work_ to put together. With LLMs I can basically speedrun through my requirements that require tons of boilerplate. The velocity is incredible compared to if I would be doing this by hand. Sometimes the LLM outputs total garbage. Then you don't accept the output, and start again. The hardest parts are never coding but design. The engineer does the design. Sometime

s I pain weeks or months over a difficult detail (it's a sideproject, I have a family etc). Once the design is crystal clear, it's fairly obvious if the LLM output is aligned with the design or not. Once I have good design, I can just start the feature / boilerplate speedrun. If you have a Windows box you can try my current public alpha. The bugs are on me, not on the LLM: https://github.com/AdaShape/adashape-open-testing/releases/t...
