# Fit Section

**AUTOCAD PRO** **REVIT** **bricscad pro** **ULTIMATE**

## **Line-Tools | Fit Section**

### **Command Line**

- **AutoCAD / BricsCAD: CWFITSECTION**

This tool allows adjusting CAD objects, such as polyline, line, arc, or circle, to accurately fit a point cloud.

### **Using the Tool**

> [!NOTE]
> **Note:** Before using this tool, it’s necessary to create a slice and draw an outline of the necessary CAD object. Refer to the [QuickSlice](/v1/docs/cloudworx-quickslice) page for more details.

To fit CAD objects to a point cloud slice, follow the steps below:

1. Click the **Fit Section** button in the **Line-Tools** panel or type a [command line prompt](/v1/docs/cloudworx-fit-section#command-line) specific to the preferred CAD system and press **ENTER**.
  1. The **Best Fit Section** dialog appears.

2. If necessary, modify the preconfigured settings in the **Best Fit Section** dialog. Refer to the [Configure Auto-Fit](/v1/docs/cloudworx-configure-auto-fit) page for detailed descriptions of each setting.
3. Then, click **Pick** in the upper-right corner of the **Best Fit Section** dialog.
4. When prompted to select the object to adjust, zoom in to the section of a polyline that currently doesn't fit a point cloud well and select it. Then, press **ENTER**.
  1. If the fit quality does not meet the **Point Accuracy**, the fit is rejected.
  2. Objects that can be selected are line, arc, circle, 2D polyline, 3D polyline and light-weight polyline. Inserted blocks and 2D polylines representing meshes or fit curve objects are not supported.
  3. For best results, work in a viewpoint aligned to the plane of the slice.

  4. The least squares algorithm will calculate the best-fit polyline to the cloud points.

5. Continue picking points for each section or object you want to fit, then press **ENTER**.

The section is aligned to the center of the point cloud slice.
