Ploterr Site Massing playbook is live, built with Floorkit on OpenGeometry. OpenGeometry powers geometry creation and editing in the browser. Floorkit builds on the kernel with editable building models, editors, and technical drawings. Ploterr brings these pieces together in Site Massing, a playbook for building your own app to explore building size and placement before detailed design. Try Site Massing and inspect the recipe. #cad #architecture #design

Floorkit is the first toolkit from @getploterr, and Site Massing is our first Playbook. More playbooks. More toolkits. All from the Ploterr family, built on OpenGeometry. What playbook would you want us to build next? ploterr.com/floorkit/?utm_so…

Looks like @opengeometry has got competition. And it’s NVIDIA. Check out usd-brep by @nvidiaomniverse They’re cooking, and we believe we are cooking harder and can take this even further. That’s the fun of competition. The bar keeps rising, and when we build in the open, the whole industry gets more to build on. Open source is the future of CAD. Seeing NVIDIA invest in a geometry kernel makes me even more confident in the direction we’ve taken. Meanwhile, the CAD industry still has another subscription to sell you! We are coming, and we will change that radically with @getploterr. Toolkits are already out, next is our app! Let’s give people more to build with. #cad #opengeometry #nvidia #design #architecture github.com/NVIDIA-Omniverse/…

Floorkit 1.1.0 is now ready for your agents. In just one week, we’re already moving fast. You and your agent should be able to inspect the design, adjust it, and undo changes. You should also be able to keep working on it yourself. People and agents should work on the same saved building project. This release includes 👇 Agent Commands Batch Operations Project Structure Versioning Your app brings the AI model. Floorkit provides the building tools and geometry. #cad #architecture #geometry #design

Let your agents build the next CAD app. We released Floorkit this week, and someone already used an agent to help build their own CAD app with it. Humans and agents are both building with Floorkit. @advancedcskills built a test app, manually traced architectural drawings, and made an editable model with scaled plans in a single afternoon. You know what your workflow needs. We want to put the ability to build it in your hands. Let's see what we can create collectively. Try Floorkit, give your agent the documentation and tell it what you want to build. It's that simple! Let's see what unfolds. If you or your team is building a CAD app, this one's for you. Built on @opengeometry. More toolkits are coming from the @getploterr family! #design #architecture #cad #bim

Yes, we reinvented the wheel. Funny how “don’t reinvent the wheel” can start to sound like “rent ours instead.” Should someone else’s roadmap decide where your ideas stop? For us, that foundation is geometry. We built it ourselves because we wanted control over how it works, what it can become, and where we take it next. That meant taking responsibility for it too. But the decision is paying off. We’re developing faster because we can change the foundation itself. Floorkit is one result of that decision. Built on the @opengeometry kernel, it gives you the tools to build your own browser-based CAD authoring app. Making it available was our first milestone. @getploterr is what we’re building next on that foundation. We’re bootstrapping this, and seeing people try it, share it, and build with it means a lot to us. To everyone who’s supported us along the way, thank you for helping us get here. Now I want to see what you build. What workflow have you been waiting for someone else to fix? The first milestone was to prove something. The next is to conquer. See you at the next milestone. #cad #opengeometry #architecture #design

Introducing Floorkit, launching today! Built on the OpenGeometry kernel and powered by @getploterr. We're releasing a toolkit for designing physical structures that other teams can integrate into their apps and workflows, starting with architecture. We built the geometry kernel. Floorkit puts the building model, editing commands, 2D and 3D editors, and drawing tools around that foundation into your hands. A structured JSON document sits at the centre, giving humans and agents the same building model to read and edit. That's the step we're taking today from a geometry kernel to the building blocks for your own design software. Bring your workflow and build it with Floorkit. More details in the thread below. #cad #buildings #design #architecture

Already building with Three.js? Bring Floorkit into your scene. Install @opengeometry/floorkit from npm, and it just works. Your app owns the camera, lights, and render loop. Floorkit builds the building geometry, and you change the model through edit commands. Try it in your app, and tell us what you'd connect next.

The next CAD tool could come from your team. With Floorkit, you can build on the OpenGeometry kernel and shape the software around your expertise. Your interface, your workflow, your choice of AI models, with CAD authoring, editing, and drafting underneath. Architecture is the starting point. We plan to grow a family of toolkits for designing across more of the physical world. Bring the problem you know best. We are listening. Explore Floorkit here ploterr.com/floorkit?utm_sou…

Be ready, we’re launching the toolkit for architects. Take control of how you design. Bring your own LLMs. Turn ideas into plans. Go from prompt to geometry to drawings. Shape the workflow around the way you want to design. Build your own tools, connect the pieces, and let the toolkit handle the rest. Release goes out this weekend. Sign up for updates. DM for early access! #architecture #cad #design

We’re building OpenGeometry from scratch, a free and open-source geometry kernel for the web. And we’re building our own @getploterr design tool on top of it. Follow the journey and sign up for updates ploterr.com/

Yes, we used Astra to do this. Introducing styles to Floorplans! But here is the twist. Astra did not draw a single wall or generate the SVG itself. It decided what to create and called the @opengeometry API. OpenGeometry handled the geometry and rendering. #cad #architecture
