Generative Design Updates
A More Guided Generative Design Experience
We’ve improved Generative Design to better guide you as you build a site, not just at the end, but throughout the entire process. As you lay out a site and adjust presets, filters, and key inputs, TestFit now automatically shows layout options that best fit what you’re trying to achieve, helping you stay aligned with your goals as you work.
To make this easier to manage, you’ll now see a new panel to adjust all of your key parameters in one place, like unit counts, parking targets, or building size limits. This makes it simpler to fine-tune your criteria and quickly see how different inputs affect the options TestFit generates.
We also updated the layout so you can expand these options when you’re ready to explore alternatives, then collapse them to focus on detailed editing in the canvas. This creates a smoother flow between setting up a site, reviewing options, and refining a design, while TestFit continuously works in the background to find better-fitting layouts when they’re most helpful.
Web Updates
Web Deal Creation
You can now create and start evaluating deals directly in the browser with Web Deal Creation. This new capability allows teams to instantly spin up, configure, and analyze new opportunities in the web platform without launching the desktop application.
By removing setup friction and keeping everything within a single connected environment, teams can begin feasibility analysis faster, collaborate earlier, and maintain momentum from the moment a new opportunity appears.
General Updates
Define Site Boundaries from KML/KMZ
You can now upload KML or KMZ files to quickly define site boundaries in TestFit. Once uploaded, the polygons contained in the file appear on the map and can be selected to create your site.
This removes the need to manually trace boundaries from PDFs or external maps and makes it much easier to start projects using geographic data that’s commonly available from planning tools, GIS platforms, and public datasets.
Housing Updates
Custom Courtyards - Check out the dedicated article here
Courtyards can now be generated using minimum distance values instead of being tied strictly to building height ratios. This gives you more flexibility when configuring buildings, especially on higher-density sites where height-based courtyard sizing could limit viable layouts.
TestFit handles these variations automatically, so you don’t have to manually adjust building massing to create different courtyard dimensions. This allows the system to explore more building configurations while still maintaining unit mix, vertical constraints, and other project parameters.
Details:
- Added tag filtering and editing for assemblies in the Library panel.
- Added support for image layers in the retail building editor.
- Image layers now render over their parent layers, allowing them to be used to decorate massing.
- Draw Rectangle tool now accepts separate keyboard input for width and height.
- Added "Edit Assembly" and "Make Unique and Edit" options to the assembly right-click menu.
- Added "Add Units" option to the building layer context menu.
- Added Ctrl + Shift to merge and Shift to split blocks on high-density mass.
- Underground garages are no longer affected by road cuts.
- USA & Canada Parcels data layer can now be enabled in metric files.
Reported Issues & Bug Fixes:
- Fixed offset layers shifting to wrong edges when the parent shape is rotated.
- Fixed stair and lift placement in podium perimeter and interior parking.
- Fixed elevator cores not extending to garage level.
- Lowered maximum courtyard aspect ratio from 100 to 10.
- Fixed high density units being on townhouse layer when exported to DXF.
- Fixed outside corner units sometimes not being placed.
- Fixed delete key not working to delete a selected site.
- Fixed parking gaps overlapping with elevators and stairs.
- Fixed inside/outside corner units missing in some solves.
- Fixed merging block guide nodes producing different results depending on which side of the gap was clicked.
- Fixed rect fill layers not being selectable when dragged outside the site.
- Fixed building spine cutting through void on upper floors.
- Fixed manually-placed stairs in corners not appearing on upper floors.
- Fixed custom stall lines not drawing in 3D.
- Fixed custom stall lines not drawing in SketchUp or glTF exports.
- Fixed sites with complex boundaries sometimes failing to solve with larger setbacks.
- Fixed cores failing to place when "wrap units into core" is disabled.
- Fixed warehouse space drag snapping to cursor.
- Fixed camera drift when resizing warehouse attachments by dragging.
- DXF exports now include unit info for correct scaling by default in apps that support it.
- Improved efficiency of metric solves.
- Fixed space offsets not affecting building spines.
- Fixed adding an offset to retail removing trees from park.
- Fixed being unable to use offsets for anything other than voids.
- Fixed void offset not creating a buffer zone around its parent.
