# Guided Workflow | Create The Preparation File

> [!NOTE]
> Start the software in **Desktop Mode**.

The preparation file is mandatory to start a [BIM Inspect](/v1/docs/cyclone-3dr-biminspect) workflow. It must include separately data to register your point cloud and data which will be inspected.

The goal of this step is to prepare a file containing three BIM objects from the content of the IFC file (a building model):

1. **site:** the main model, used for the registration with the scan.
2. **columns:** the specific elements of the BIM project we want to inspect.
3. **other:** other element that may serve for other purpose.

## Import BIM data from an IFC file

> [!NOTE]
> Import **site.ifc** ([download](https://www.cyclone3dr.com/download_helper.php?File=Cyclone3DRSampleData/site.ifc)) through [File > Import](/v1/docs/cyclone-3dr-importcadfilec).

Unfold **GROUND**, then load only **Wall**, **Slab** and **Covering**. This selection filters which parts are going to be used among all parts available from an IFC or RVT [import](/v1/docs/cyclone-3dr-importcadfilec).

Validate with **OK** and hide it.

Ensure the output object is named **"site"**.

Imported model (site)

## Create the BIM objects relevant for inspection

Copy-paste the object named "**site"** and rename it **"columns"**. Now, double-click on this copy to edit it and modify the selection.

Unfold **GROUND,** then right-click on the **Column** folder and select **Load only selection.**

Validate with **OK**. The object remains hidden, but its content has been updated.

Repeat the previous step with loading only **Flow segment** and **Door** groups**.** Name this object **"other"**.

> [!NOTE]
> Tip & Tricks  
> 
> It is also possible to filter the selection by keywords (component name, IFC type, etc.).

## Validate the preparation file

Save this file as **BIMInspectionPreparationfile.3dr**, close it.

Once the preparation file is done, you can use it for all on-field analyses through the BIM Inspection workflow in [Touch Mode](/v1/docs/cyclone-3dr-touch).
