ArcSpan — Parametric Bridge and Viaduct Builder
JuanBautista
Are updates included?
The purchase includes 12 months of product updates and support through Superhive.
What information should I provide when requesting support?
Please include:
- Blender version
- ArcSpan version
- Operating system
- Steps to reproduce the issue
- Relevant screenshots
- Complete error message or Blender system-console output
This information makes diagnosing the problem substantially faster.
Why does Blender report a duplicate ArcSpan installation?
This normally means an older ArcSpan copy exists in another Add-ons or Extensions location.
Disable and remove previous installations, restart Blender and install only the current ArcSpan_v1.6.32_marketplace.zip.
Does ArcSpan require additional add-ons or Python packages?
No external Python packages are required. ArcSpan uses Blender’s included Python environment and APIs.
Can I use the generated bridges commercially?
Yes. You can use rendered images, animations and exported bridge assets created with ArcSpan in personal and commercial projects.
The ArcSpan add-on source code itself is distributed under GPL-3.0-or-later.
Can I export the generated bridge?
Yes. ArcSpan includes LOD generation and GLB export workflows, along with QA reports and delivery-related metadata.
What does the integrated QA system check?
ArcSpan QA reviews generated geometry and configuration for issues involving dimensions, clearances, support relationships, roadway settings, object consistency and export readiness.
Some supported problems can be corrected with deterministic fix operations.
Are vehicles, buildings or landscape assets included?
No. ArcSpan generates the bridge system and related roadway details. Vehicles, complete cities and detailed landscape libraries are not included.
Does ArcSpan perform structural engineering calculations?
No. ArcSpan is intended for visualization, conceptual design and digital content production.
Its QA system checks internal geometric and configuration rules, but it does not provide certified structural analysis or replace professional engineering software.
What types of bridges can ArcSpan generate?
ArcSpan focuses on beam, girder, viaduct and elevated roadway systems with configurable decks, supports, piers and roadway components.
Can ArcSpan generate curved and elevated bridges?
Yes. ArcSpan supports straight and curved routes, elevation changes, banking and elevated ramp configurations. Extremely abrupt curves or elevation changes may require guide adjustment.
Can I edit the bridge after generating it?
Yes. You can modify the guide curve or ArcSpan settings and then use Update or Rebuild to regenerate the bridge.
Direct mesh editing is best reserved for the final stage, after the parametric design is approved.
Where can I find ArcSpan after installation?
Open the 3D Viewport and press N to display the sidebar. The ArcSpan panel will be available there after the add-on is enabled.
How do I install ArcSpan?
Download ArcSpan_v1.6.32_marketplace.zip and install it directly through Edit → Preferences → Add-ons → Install from Disk. Do not unpack that installer ZIP. The original customer bundle contains the same installer plus documentation; if using the bundle, extract only its outer archive first. Keep one ArcSpan installation enabled.
Which operating systems are supported?
ArcSpan has been validated on Windows. It does not use external executables or platform-specific dependencies, but macOS and Linux have not yet received the same level of release validation.
Which Blender versions are supported?
ArcSpan 1.6.32 is supported and verified on Windows with Blender 5.0.1 and 5.2.1 LTS. Its manifest declares Blender 4.2.0 as the minimum, but 4.2 and intermediate releases have not been separately validated. Use one of the verified configurations for the documented workflow.
What is ArcSpan?
ArcSpan is a Blender add-on that generates editable bridges, curved viaducts and elevated ramps from guide curves. It coordinates the deck, supports, roadway elements and presentation details as one configurable system.
