# Configure Auto-Fit

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

## **Line-Tools | Configure Auto-Fit**

### **Command Line**

- **AutoCAD / BricsCAD: CWBFSETUP**

This command allows adjusting settings for auto-fit polyline tools.

### **Using the Tool**

When the tool is activated, the **Best Fit Polyline Settings** dialog appears.

Adjust the settings as required:

- Select the **Lock Shape (Rigid)** check box to adjust the position and orientation of the section without changing its shape.
- Select the **Snap and Grid** check boxto align the segments of the section to the Snap X spacing and Snap Y spacing of the current CAD **Snap and Grid** settings. The values for **Angle, X base** and **Y base** must be set to zero.
- Select the **Polar Tracking** check boxto align the segments of the section to the Increment angle of the current CAD **Polar Tracking** settings.

> [!NOTE]
> **Notes**
> 
> - **Polar Tracking** and **Snap and Grid** use the current UCS as a reference. The UCS must be aligned to the plane of the slice to use these options.
> - When the **Polar Tracking** or **Snap and Grid** check box is selected, CloudWorx applies the values of the current CAD settings even if these options are not enabled in CAD.
> - To change the current CAD settings, click the browse icon (…) at the right of the **Grid Locks** field.

- Enter the preferred combination of tolerances:
  1. **Intersection Tolerance** determines and maintains the connectivity of endpoints of open curves to other curves. If the endpoints are initially close to each other, use a smaller tolerance. Large tolerances may generate unexpected results.
  2. **Perpendicular Tolerance** adjusts angular relationships between segments to be perpendicular or tangent if the error falls within the tolerance entered. Enter a value between 0.0 deg and 45.0 deg.
  3. **Max. Point Distance** determines how far the points are from their ideal cloud points. Lines are not adjusted more than the value entered (the default is 0.1m or 20 times the RMS error); if this value is too large, it increases the uncertainty of the fitting results.
  4. **Point Accuracy** displays the sampling error of the original point cloud.
