Release Date: July 29, 2026
Overview
This release brings a completely redesigned Pressure Relief tool, now with landmark-anchored shapes, adjustable falloff and smoothing controls, and the ability to save your favorite shape combinations as reusable presets. We’ve also added vertex color support for PLY files, a safer Switch to Opposite Foot function that auto-backs up your design JSON, and a standalone Toe Box tool separated from the Channel tool. On top of that, ankle angle, length, and width measurements now show up right alongside circumferences in the measurement panel.
Key Features
Pressure or relief
The Pressure Relief tool has been completely redesigned.
In the initial view, users can either load a preset or add a new shape. Clicking Load opens a file browser dialog for importing a preset JSON file.
The Add New Shape dropdown contains all available predefined shapes. When a shape is selected, it is automatically placed on the foot model at its predefined position using its default parameters. Multiple shapes can be added consecutively, as the dropdown remains open until it is manually closed.
After adding a shape or loading a preset, the Save Preset button becomes active. This allows all currently listed shapes and their settings to be saved as a preset.
The shape list always contains one active item. The active shape is displayed with a red contour, while inactive shapes are shown in gray. By default, the first item or the most recently selected item is set as active.
The active shape can be configured by adjusting the height of all inner control points, the height of the selected inner control point, the slope controlling the falloff between the inner and outer points, and the outer smoothing option, which provides additional refinement of the outer boundary.
In addition to the predefined shapes, custom shapes can be created. Control points for the inner and outer boundaries can be added or removed independently, and individual shapes can be deleted.
Some shapes can be anchored to anatomical landmarks. For example, medial malleoli shapes can be anchored to the medial malleolus landmark. When creating a new shape, a landmark can be selected as an anchor, ensuring that the shape is automatically snapped to the correct position when a preset is loaded.
When the Apply button is clicked, all shapes are applied to the scan simultaneously. Once applied, the shapes can no longer be edited individually. This operation can only be reverted using the global Undo or Reset buttons.
Separate the Toe box tool from the Channel tool
The Toe box tool has been separated from the Channel tool and is now available as an independent mesh editing tool.
Show measurements options
Ankle angle, length, and width measurements can now be displayed on the right-hand measurement panel alongside circumferences.
Improved Switch to opposite foot function
The “Switch to opposite foot” function for paired AFO designs has been updated. When the button is clicked, a local backup of the design JSON file is automatically saved while parameters are transferred in the background.
PLY texture support
Vertex colors are now supported for PLY files. Models with fused vertex colors or embedded texture data can be imported directly without requiring a separate texture import step.
Fixes and Improvements
Positive model generation artifact
Visual artifacts that occasionally appeared during positive model generation have been fixed.
Texture disappears after applying channel, flared edges, or stirrup
Model textures are no longer lost when remeshing occurs during the use of the channel, flared edges, or stirrup tools.
Positive model mode unavailable for custom templates
An issue where project files loaded into 3D shell mode instead of positive mode and could not be switched back has been resolved.
Channel tool application changes orientation
Orientation shifts caused by landmark movement when applying the channel tool have been corrected.
