TestFit Release - 5.10 - Drive-Thru, Web Edit & Revit 2026

Retail Updates

Solve Drive-Thrus Directly

Expanding our capabilities for retail sites, you can now automatically solve for drive-thru’sdrive-thru’s! TestFit handles turn radius and automatically tabulates stacking count based on lane length, path and pickup window location. This capability can be utilized for any build that requires an orderly drive-thru - QSR’s, Banks, ATMs, pharmacies, and even gas stations!

Adds drive-thru solving to massing with automatic stacking and obstacle avoidance.

Web Updates

Edit a Deal on the Web

You can now edit your TestFit model directly in your browser—no need to open TestFit on your desktop. It’s a faster, lighter way to keep your model updated on the go. 

Export Reports Directly from Deal Pipeline

Reports can now be created and edited directly in the browser—no need to export data or switch tools. Sort views by scheme or site, toggle between 2D plans and 3D perspectives, and highlight key metrics in the deal overview.


Rearranging or removing sections is quick and intuitive, giving you full control over how information is presented. Once curated, reports can be shared via live link or exported to PDF for client and investor presentations, making communicating feasibility and moving deals forward easier.

General Updates

Search and Edit Faster for Parameter and Presets Search

You can search across all sites and layers for any parameter, then navigate to it or update it directly in the results view. This gives you faster access and tighter control over your data, especially on complex or layered sites where manually clicking through each element would slow you down.

Streamline Workflow with the Combined Generative Design & Presets Panel

To speed up your iterative process, we’ve merged the generative design and presets panels into one streamlined interface.


Easily move between presets and generative workflows without switching tabs to explore options, compare schemes, and refine layouts—all from one place. This update also includes several usability improvements to speed up iteration.

Export Models to Revit 2026

Revit 2026 is now supported for geometry exports, allowing teams to carry TestFit data directly into the latest version of Revit for documentation and coordination.
