This makes parameters a usable feature to drive powerful parametric and automated connection modeling.
UX
The UX of the Developer tab has significant features included.
- Parameters and model properties are now split into tabs in the side panel. With Parameters being positioned as the 'primary' element of this functionality.
- It is possible to link parameters to model properties directly from this tab using the add model property link button.

- A Value output column has been included so the user can see the calculated output in real-time.
- A custom Parameter Validation is available to allow template creators to notify others of limitations to their parametric designs.
- The user can select a validation 'type' and choose whether to warn the user or restrict the set to the model.
- If validation is set and passed (=true), a success icon displays.
- If validation is set and not passed (=false), either a warning or error icon displays.
- If no validation is set, no icon displays.

- A unit selection is available to allow users to see the output value in their preferred unit type (set by program settings). Note: all calculations and expression inputs are still to be in basic SI units.

- The Model Property Dialogue works in the following way:
- An Is active column has been added to model properties to show the user if the specific property is visible in the current UI of the program.
- A parameter can now also be edited on a particular added model property.
Clever Features
In addition to the core functionality, we've included (v26.1) a few smart tweaks to help you build parametric templates.
- Developer tab expression editor: code completion and signature hints while typing.

- Add model property link dialog: each property shows a dimmed context subtitle; duplicates get ordinals.

- Bolt Assembly parameter value type: combo + "+" button (MPRL picker) in the Design tab.

- Parameter groups: authored in the Developer tab (add, rename, reorder, delete), rendered in the Design tab as named separators that can collapse; transparent to evaluation, the REST API and templates without groups.
