2. Select the **Result Patch** options to determine the shape of the patch:
  1. **Convex Hull** produces a convex polygon that surrounds the points.
  2. **Minimum Rectangle** produces a rectangle with the minimum surface area that surrounds the fit points.
3. Click the **Pick** button, then pick a point on the cloud.
  1. The patch will be fitted using the points in the region that best define a planar surface, and the results will be displayed.
  2. If the fit quality does not meet the **Maximum RMS Error**, the fit will be rejected.
4. Continue picking points for each patch that needs to be fitted, and then press **ENTER**.

#### **To fit a patch via a fence:**

1. Follow Steps 1-2 described in the [To fit a patch by selecting a cloud point](/v1/docs/cloudworx-patch#to-fit-a-patch-by-selecting-a-cloud-point) section.
2. Click the **Fence** button.
  1. To change the type of fence to be drawn, type **POLYGON**, **CIRCLE**, or **RECTANGLE** at the CAD command line and press **ENTER**.
3. Draw a fence.
  1. The patch will be fitted using the points within the fence, and the results will be displayed.
  2. If the fit quality does not meet the **Maximum RMS Error**, the fit will be rejected.
4. Continue drawing fences for each patch you want to fit, and then press **ENTER**.
