Frequently asked questions
Which models are supported? Why did an import fail?
The app currently supports .glb files up to 60 MB. Renaming another file's extension does not convert it to GLB. Export a GLB containing triangle meshes and fully embedded textures and buffer data.
If an import fails, check whether the file opens in another 3D viewer, then try simplifying the model, reducing texture sizes or disabling additional mesh compression. A GLB that opens elsewhere may still use extensions this app does not support. Large models also require more processing time and device memory.
Why do the colors, details or generated result look different?
Voxelization and matching to brick colors can change details and colors. The app mainly uses the first available base-color texture, or a single material color if no usable texture is available. It does not preserve the separate colors of multiple materials or vertex colors. External textures and some compression extensions may also affect the result.
After adjusting model size, color or brick settings on Home, select Generate Building Plan again. Once generated, select Edit Voxels to refine the base shape, then Generate Brick Preview. Generation may rearrange bricks and add connecting bricks, so the final brick preview may differ from the base shape in the editor.
Why have my free saves run out? Is Pro a subscription?
The iOS free version allows 3 newly generated plans to be saved. A save is counted only after a new plan is successfully saved. Selecting Save & Start Building for the same saved preview does not count again; regenerating and saving a new project does. Deleting projects does not restore the allowance, and reinstalling does not guarantee a reset.
Brick Workshop Pro is a one-time, non-consumable in-app purchase with no automatic renewal. While Apple confirms a valid entitlement, Pro removes the limit on saving newly generated plans. The free version also supports importing, previewing and generating plans. The App Store price shown in the purchase panel applies.
How do I restore Pro after reinstalling or changing devices?
If Pro is not unlocked, sign in to the App Store with the same Apple Account used to buy it. Open Me in Brick Workshop, select Brick Workshop Pro, then choose Restore Purchases in the purchase panel while connected to the internet. If the app has already recognized a valid entitlement, it shows Pro as unlocked without requiring another purchase.
If Pro does not restore, check that in-app purchases are allowed on your device, then close and reopen the app before trying again. Restoring a purchase restores Pro access, not local projects from your previous device. See Apple's restore-purchase guidance.
What if a purchase cannot connect or I have a billing issue?
Check your connection and App Store account. If pricing fails to load or the app cannot connect to the App Store, close and reopen the app once your connection is restored, then try purchasing again. If the app says the in-app product is not configured, contact the developer. If you were charged but Pro did not unlock, try Restore Purchases before initiating another purchase.
For refunds or billing concerns, use Apple's Report a Problem page. Apple determines refund eligibility and the outcome. A refund or revocation may remove Pro access when the app receives updated entitlement information. See Apple's refund instructions. Contact the support email above for app issues.
Do importing, generating or purchases need the internet?
Once a file is downloaded to your device and its resources are fully embedded, model parsing, voxel editing, plan generation and project saving can run locally without uploading the model. A file stored in iCloud Drive or another cloud service may need an internet connection to download. If a GLB references textures or buffers at external URLs, the parser may also automatically request them. There is no separate control for these requests.
App Store pricing, purchases and an explicit restore may need an internet connection. Pro access already verified locally does not require a continuous connection. The app has no project cloud sync; restoring Pro restores the purchase entitlement only. The privacy policy explains external requests and system device backups.
Where are projects stored? Can I recover a deleted project?
Projects and building progress are stored on your device. Reopen a saved project to continue building; the app provides no project cloud sync of its own. Once confirmed, deletion cannot be undone in the app. There is no in-app trash, and the developer has no remote copy to restore.
Deleting the app may remove local projects, and restoring Pro does not restore projects. Keep important source GLB files separately so you can import and generate them again. Regenerating does not recover the original project's edits or building progress. Recovery through a system device backup depends on your backup.
How do I delete a project or learn about privacy?
On My Projects, open the project's more-actions menu, choose Delete and confirm. This deletes the saved project without deleting the source GLB stored in Files or another location, and does not restore used free saves.
Read the Privacy Policy for details about models, local data, on-device free-save counts, Apple services and support emails.
