# Planar Sections

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

This command computes sections or set of sections of selected mesh(es) or cloud(s), computing the intersection between parallel planes and select object(s).

> [!TIP]
> ### Requirements
> 
> Select all the mesh(es) or cloud(s) on which you want to calculate sections and launch the command.

**For meshes:**

1. Enter the [direction](/v1/docs/cyclone-3dr-definenormaldirection) of the axis.
2. **Extraction method**: choose where the sections are calculated:
  - **Regular**: with a regular step, for example, one section each 10m.
    - **All over:** all over the object. Check **Pass Through** to force the section to pass through a given point.
    - **Custom**: only between two points
  - **List of values**: pick points or enter values to choose where to calculate sections.
3. Check **Chain opened sections** option to chain the section. The "chaining" is an operation which connects all the opened polylines on one cut plane.
  - Check **Offset** option to make an **Offset** of the link connecting different polyline pieces. Chaining sections is very interesting for laser cutting tool paths were you need continuous polylines. **Offset** can be useful to keep track of the holes or undefined zones in the model.

**For point clouds, there are further options:**

1. Enter the **Slice thickness** in which the points of the cloud will be taken into account when computing the sections.
2. Set the **Chaining distance** in order to set the connection between opened polylines.
3. Activate or not the **Noise reduction** to keep only the best points of a section.

**For meshes with inspection data, you have the option to create section with inspection data.**

- **Create inspected section:** select to create a section with inspection data
- **Magnify:** Scale the pegs length

> [!NOTE]
> ### Technical information
> 
> Sections on an inspected mesh
> 
> If the sections are computed on the inspected mesh (considered as well as the reference or measure), the sections will keep the inspection values of the mesh. **It means that the hair diagram will not be, in most cases, in the plane of the section**. It depends on the type of inspection (2D or 3D).
> 
> Restriction: when a mesh was colored as the measure with a cloud as reference, this capability is not available.

> 
> If you want to have a hair diagram on the plane of the section:
> 
> - Do an inspection in the direction of the plane and then do a section with this plane.
> - Do a section in the plane on both entities (reference and measure) and then do an inspection of this polyline/set of polylines.
