INK TO BRICK vs GPT-6 Astra Ultra for a house in Blender

Choose INK TO BRICK first when a source floor plan should determine the rooms, walls and openings before Blender work begins. Choose Astra-first when direct scripted authoring in Blender and bespoke scene development matter more than recovering a drawing. The practical route can combine both.

INK TO BRICKReviewed

Where each one fits

Choose INK TO BRICK if

A source-grounded reconstruction you can inspect in the browser before exporting GLB, glTF, OBJ or another downstream format.[5]

Choose GPT-6 Astra Ultra with Blender if

Flexible Blender authoring through its Python API or a Blender MCP server, with the ability to inspect renders and iterate on custom scene detail.[4]

Try an edit before bringing your own planMove an opening or furniture in this authored sample. Check plan and 3D, then undo. This is practice, not proof of conversion accuracy. No account needed. See your home in 3D before you pay; editing it needs a plan. This practice demonstrates manual editing; it is not a reconstruction benchmark or an authenticated export trial.

Task by task

Your taskINK TO BRICKGPT-6 Astra Ultra with Blender
Published software costEvery plan exports GLB, OBJ, USDZ, PDF, SVG, images and more. Pro and Team add DXF, DWG, SKP, IFC and STEP for recurring professional work.[7]GPT-6 Astra Standard short-context API pricing is $10 per million input tokens, $1 cached input, $12.50 cache write and $50 output. Blender compute, tool hosting and review are separate.[2]
Starting from a floor planThe product reconstructs a conceptual model from the uploaded plan; the user checks outline, scale, rooms, walls and openings before export.[5]The prompt and Blender tools must translate the drawing or brief into geometry, then the user must verify the result against the source.
Automation boundaryPro and Team include MCP tools for supported project inspection, model edits and pinned JSON or GLB exports. Use the web app for drawing uploads, reconstruction and the broader export library. MCP does not control Blender; Team includes API access.Astra can operate Blender through Blender Python or a separate Blender MCP server. The tool bridge determines which scene actions are available.[4][3]
Time claimProcessing and review time varies with the drawing and queue. The product does not promise a fixed conversion time.No official house-build elapsed-time benchmark is published in the cited case study; its 30-second figure is the duration of the finished tour.[4]

See the editing workflow

For an API or model-file workflow, compare the review interface as well as the file. These captures show the expert tools and linked plan/3D views on the authored sample duplex. Imported geometry needs a separate check of which objects and controls remain editable.

The demonstrations use native elements in the sample duplex authored in INK TO BRICK.

Views and screenshots

Switch between plan, 3D and split, change how walls and levels show, preview and walk through the home, and save a picture of the view.

A subscription and metered tokens are different units

OpenAI documents the API model as gpt-6-astra with reasoning efforts through max. “Ultra” can name a client preset, but it has no separately documented flat API price. Token cost depends on cumulative input, cache writes, cached input and output, while a single request above 272,000 input tokens uses higher long-context rates.[1][2]

Compare incremental and first-time cost separately. An existing INK TO BRICK or Codex subscription may cover work within its allowance, while OpenAI API tokens remain metered usage even when account credit was purchased earlier. A new workflow must also account for Blender Python or MCP setup, retries, compute, verification and the refinement work both routes still need.

The strongest workflow may use both

Reconstruct and inspect the source plan in INK TO BRICK, export GLB, then use Astra with Blender Python or a Blender MCP server for bounded scene tasks. That keeps the source comparison before the creative modeling loop and gives the agent a file that can be reopened and checked.

Neither route turns an uncertain drawing into survey truth. Verify dimensions, topology, object hierarchy, materials and unintended changes in the destination, and use qualified professionals for structural, code and construction decisions.

Review the evidence, then try your source

Check a wall or opening the rendering could hide, not just the final picture. The Isla de Pascua story combines original SketchUp and plan dimensions with MCP/AI refinement using photographs and video; it is a visual interpretation. The duplex is an authored sample demonstrating editor and presentation work, not proof of automatic reconstruction. Use these examples to choose the review you need to perform on your own drawing.[8][9]

Try your clearest one-floor plan. You see your home in 3D before you pay, and a plan is needed to edit it. A failed build goes back to your monthly builds. Check the required export and final checkout first. Pro and Team include MCP; Team includes API access. The account, editor and billing application currently use English.[7]
