### Parametric Edit

Live date: Aug 26th, 2021

User type applied: for Enterprise account (which bought parameterized editor)

**\[Value\]**

* Now, the customization tool has been added to the British unit configuration, the unit can be switched in the setting to realize the conversion of length.

Now, the customization tool has been added to the British unit configuration, the unit can be switched in the setting to realize the conversion of length.

**Notice：** All parameter values are converted according to the length.

In order to guarantee the accuracy of parameter value conversion of area and quantity type. You can perform the following operations:

### 1、Single-object Edit

* \[Entrance\]

\[Entrance\]

Customize model (parameterized model, 3D model) variable edit panel \>\> The unit type

* Optional:  

  General: default length conversion  

  Length: need conversion  

  Area: need to convert to ft square  

  Quantity: need no conversion

Optional:  

General: default length conversion

### 3、Identify the parameter unit type on the model in the tool

When switching the unit to ft in the toolset, it is necessary to identify the type of parameter unit on the model and convert according to different types:
