INK TO BRICK vs MeltFlex: GLB output or project editing

MeltFlex’s API can return a real GLB, not only an image. The decision is whether your workflow needs a conversion endpoint or a project for ongoing design review.[1][3]

INK TO BRICKReviewed October 7, 2026

Choose INK TO BRICK if

You want a user-facing project with corrections, alternatives, sharing and export rather than building those interactions around an API.[3][4]

Choose MeltFlex if

You are integrating image or GLB generation into an application and can build the review experience around the returned artifact.[1]

Task by task

Your taskINK TO BRICKMeltFlex

Price and accessYour first floor is built in 3D free. Pay to edit it and save. Floor packages start at USD 4.99; API access is arranged separately from Pro/Studio MCP.[2]Credit-based API: the reviewed reference lists 10 credits for a render and 100 for a floor-plan GLB.[1]

Continue editingUse architectural controls for recoverable native elements and object transforms for mesh geometry.[3]A GLB can enter a 3D tool; the API contract does not establish native architectural wall parameters.[1]

Output typeReview an editable graph of supported native elements and imported objects.[4]Choose a hosted image or textured/bare GLB mesh.[1]

Integration responsibilityThe product supplies project review, save, alternatives and sharing; evaluate its separate API offer if embedding is required.[3]Asynchronous conversions can return a task identifier for polling.[1]

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 mesh is useful without being a parametric building

Open the returned GLB, inspect its scale and try the exact correction you need. Moving a complete object differs from changing a hosted opening. Importing a mesh into INK TO BRICK does not automatically recover all architectural semantics either.

What we reviewed

This is a review of the public API contract, not an authenticated conversion or throughput test. The illustrated API article explains the distinction between data, images, meshes and editable projects.[5]
