| Control | Description |
|---|---|
| Name (Line) | Type a name for the generated line or click  to increment to the next available name. |
| Add | Click to add the selected points or the vertices of the selected lines to the list. |
| Remove | Click to remove the selected points or vertices from the list. |
| 3D circular arc |
Do one of the following:
|
| Create circle | Select the checkbox to generate a circle that best fits the points or vertices. |
| Use fixed radius |
Do one of the following:
|
| Radius |
If you have selected Use fixed radius, type the known radius for the circular arc. Note:
|
| Solve | Click to preview the generated line in the model view and display the Offset value in the list. |
| OK | Click to accept the generated line. |
| Control | Description |
|---|---|
| Name (Point) | The name or unique Id of the vertices in the list. |
| Included |
Do one of the following:
|
| Fixed | Select the checkbox to give a vertex a higher weight than unfixed vertices when generating a best fit line. |
| Offset |
The computed perpendicular distance from the generated line to each vertex included in the calculation. Note:
|
- Include at least 3 points to solve the best fit calculation.
- Use the computed Offset value to identify outliers.
- If you clear the 3D circular arc checkbox the generated line and its centre point are assigned the default height.
