# 3.10 Parametric UI

In certain situations, such as when using Shapediver, it may be necessary to execute Grasshopper definitions without direct access to the Grasshopper canvas. For these cases, the components in the "Param User Interface" toolbar section allow users to control the display options of Karamba3D models solely through parameter inputs.

These components are included in the standard installation but are not visible by default.

{% hint style="info" %}
To make the components visible in the Karamba3D toolbar navigate to "Karamba3D/Show Components/View ParametricUI" in the Grasshopper menu.
{% endhint %}

Selcting the above menu option makes the ParamUI section of the toolbar visible (see fig. 3.10.2).
