# Contour Lines

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

This command creates contour lines on a mesh.

> [!TIP]
> ### Requirements
> 
> Select a mesh and launch the command.

1. Define the **Step** between each contour line.
2. Choose the **Range** of the contours:
  1. **All over** to have contour lines all over the selection. Check **Pass Through** to force the section to pass through a given point.
  2. **Custom** to compute contour lines between two elevations. In this case, you have to define the range. Contour lines will pass through the **From** value.
3. Optionally, **Major contours frequency**. In this case, you need to set the interval between major contours.
4. Optionally, **Filter contours smaller than** to remove irrelevant contours.
5. Customize the aspect with **Display options**:
  1. Display **texts** or not,
  2. Change the **color** of the contours,
  3. Change the **width** of the contours.
6. Adjust the **Mesh transparency** to better see computed contour lines inside the command.
7. Set **Export** options to define texts frequency and height in **DXF/Send To** exports. These settings have to be defined according to the scale of the desired deliverable.

> [!WARNING]
> ### Notes
> 
> - Contour lines are always computed along the Z direction of the current coordinate system.
> - The export will use the currently active coordinate system.
