A level is an elevation which helps to assign and sort the steel elements into the steel structure. 1. Hide / show the input cloud with the bulb. Adjust the transparency using the slider. 1. You may also ![InputCloudFilter.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/InputCloudFilter.svg) **Filter** the cloud according to its classes: see [Auto Classification](/v1/docs/cyclone-3dr-cloudautoclassificationc). 2. Hide / show the **Environment objects**. An environment object is an object visible when the workflow has been started but it is not used by the workflow itself. 3. All levels are displayed in the **Levels** table: 1. For each one, you can **rename**, **adjust the elevation** or **delete** it. 1. Elevation adjustment can be performed by editing the value in the table or clicking into the 3D scene after selected the ![Pencil.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Pencil.svg) . 4. To **add a new level**, select ![Add.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Add.svg)**Add (+)**. 1. [Define Points](/v1/docs/cyclone-3dr-enteringpointprocedure) is launched to define the exact altitude. > [!WARNING] > ### Notes > > 1. By default: > 1. a first Level is automatically created at Z = 0 based on the active coordinate system. > 2. a new Level altitude is set to the highest level elevation plus 3 meters (or 10ft if using the imperial units) > 2. Once this workflow step is validated, no level edition, addition or removal is possible. > [!TIP] > ### Tips & Tricks > > **Define an exact Level altitude**: when [Define Points](/v1/docs/cyclone-3dr-enteringpointprocedure) is active, use XYZ mode to set an exact value (i.e “0 0 3” for 3 meters).
