# 2 Getting Started If all goes well during installation you will notice upon starting Grasshopper (GH) that there is a new category called Karamba3D on the component panel. It consists of roughly twelve subsections (see fig. 2.1). In case you do not see any icons select **“Draw All Components”** in Grasshopper's **“View”**-menu. The installation can be tested by placing a Karamba3D **“License”**-component on the canvas: it should not issue a warning or error. If not, see section [4.1.3](https://manual.karamba3d.com/troubleshooting/4.3.-miscellaneous-problems/licensing) for how to solve that issue. {% hint style="info" %} On Apple machines make sure to have Microsoft's [.NET Framework 4.5](https://www.microsoft.com/en-us/download/details.aspx?id=30653) in case of Rhino6 and [version 4.8](https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0) in case of Rhino7. {% endhint %}

Fig. 2.1: Category “Karamba3D” on the component panel

These are the subsections which show up in the Karamba3D category: | Tab | Function | | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- | | License | The **“License”-**component contained in here delivers information regarding the current type of license and how to get a pro-version of Karamba3D | | Params | containers for Karamba3D objects like beams, loads, models, . . | | 1.Model | lets you create a basic models with default settings for cross sections and materials | | 2.Load | components for defining external forces | | 3.Cross Section | contains components to create and select cross sections for elements. | | 4.Joint | for defining joints on beams and shells. | | 5.Materials | components for the definition and selection of materials | | 6.Algorithms | components for analyzing the structural model | | 7.Results | for the retrieval of calculation results | | 8.Export | for exporting Karamba3D-models to RStab or Robot via DStV-file | | 9.Utilities | contains some extra geometric functionality that makes it easier to handle and optimize models | | x1.ParamUI | components for controlling the display of models via parameter-input only | {% hint style="info" %} The colors of Karamba3D’s icons have a special meaning: black or white designates the entity or entities on which a component acts. Products of components get referenced by a blue symbol. {% endhint %} Karamba3D adds a section in the Grasshopper menu (see fig. 2.2.). There it is possible to * set the basic physical units and whether to work in Imperial or SI Units, * optimize the visibility of Karamba3D components in the toolbar, * set the language of the user interface, * edit the initial settings file and * get help
