What Occlusia does and does not do — for the people who draw, the developers who integrate it, and the companies that build on it.

What is Occlusia?
Occlusia turns 3D models into 2D technical drawings — plans, sections and elevations — with the line weights, line types, hatches, cut symbols, annotations, shadows and DXF layers you set for each object. You use it in the browser with Occlusia Studio, or through its REST API and MCP server.
Read moreWhich 3D formats are supported?
SketchUp files (.skp) saved by SketchUp 2021 or later, IFC and FBX files, and Occlusia’s own .occs models and .occp projects. Blender and SketchUp models can also be linked live with Occlusia Link: the integrations page gives each plugin’s status.
Read moreCan I generate plans, sections and elevations?
Yes, from the views your model defines: SketchUp’s section planes, Blender’s Occlusia sections, or — for an IFC or FBX file without views of its own — a plan per storey and four elevations made for you. The view being drawn is called the Active Section in the interface, whatever its kind.
Read moreCan I create section planes in Occlusia?
No. Occlusia has no section editor: views come from the model. Add a section plane in SketchUp, an Occlusia section in Blender, or an object named OCCSECTION in an IFC or FBX file, and the view appears in Occlusia.
Read moreDoes Occlusia modify my original model?
No. Occlusia reads the model and never changes it: styles, layers and page setups belong to the Occlusia project and its configuration. Renaming an object in your 3D software is how you change the style it receives.
Which export formats are available?
SVG; DXF with layers, line types and real hatches; PDF at the paper size and scale you choose, one file per view or a single document of up to 24 pages; and PNG or JPEG images. A model can also be saved as .occs, and a configuration as .occc.

Is there a REST API?
Yes: https://api.occlusia.app/v1/engine, described in OpenAPI. A session opens an engine of your own; you upload a model, run commands — open, configure, preview, export — and download the files.
Read moreIs there an MCP server?
Yes: https://api.occlusia.app/v1/mcp, over Streamable HTTP. Claude, ChatGPT, Claude Code, Cursor, VS Code and other MCP clients connect with the address alone, and sign you in with OAuth.
Read moreHow are API credits calculated?
Exports and Auto config cost what they cost in Studio. On top of that, because Occlusia’s servers do the work, opening a model costs 1 credit and each new drawing computed 1 credit; the same drawing again in the same session is free, and so are listing, reading and settings.
Read moreCan I integrate Occlusia into my own software?
Yes. For your own work, use an API key. For an app used by others, use OAuth: each user connects their own Occlusia account and spends their own credits. Serving your customers through your own account or keys, white-label or OEM use need a separate agreement.

Is OEM licensing available?
It can be discussed, under a separate written agreement. The Terms of Service do not allow redistributing or sublicensing Occlusia: only a signed agreement can, and only to the extent it says.
Read moreCan Occlusia be integrated into an AI platform?
Yes. Occlusia’s MCP server works with clients that speak MCP with OAuth, each user connecting their own account. A platform that wants to offer Occlusia on other terms — its own accounts, its own billing — needs an agreement.

Yes. Write to hello@occlusia.app about what you build and the volumes you expect.
