# Unroll

![CmdUnroll.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/CmdUnroll.svg)

This command allows you to unroll the point cloud or the mesh of a tubular shape. Two types of results can be computed:

- 3D: to have a planar view of the shape keeping the relief on the surface,
- 2D: to create a color map in 2 dimensions. This option fits well to colored or inspected objects.

> [!TIP]
> ### Requirements
> 
> Select the object to unroll (mesh or point cloud) and launch the command. You have to select the central axis of the tubular shape. There are 2 possibilities: select it before launching the command or inside the command.

1. Choose the type of result: **2D** or **3D**.
2. Define where to cut to get an unrolled result: by default it will be opened under the axis, in the Z direction (if the axis is vertical, it will be opened vertically above the Y axis).Optionally, click a point on the mesh or the cloud to define another projection direction. The axis will be projected on the mesh/cloud and you can see along which line will the object be opened.
3. Set the **Radius** to define how the map will be scaled perpendicularly to the axis. Use the actual tube radius for a neutral scale. Any local change of the actual radius will generate map distortions.
4. Define the **Unit of grid rows**: Distance or Angle. Angle will be less confusing when the actual radius is not constant.
5. After the computation, it is possible to:
  1. **Turn the result** from 90°.
  2. **Export a picture** of the current view of the 3D scene (in JPG, BMP or TIFF format).

> [!WARNING]
> ### Notes
> 
> - When unrolling a mesh, it is better to have its extremities open to have a right result.
