| 1. | Click the From plot elems button. |
| 2. | Select the plot elements (such as feature lines) that you wish to use as guides for meshline creation. |
| 3. | Specify a relative approximation tolerance for the generated splines. |
Splines are used to generate surface edges when you have the update surfaces option active in the main meshlines subpanel. These splines use the same start and end points as the generated mesh lines, but may deviate in between since they are splines while the mesh lines themselves adhere to the specified nodes.
This value is a multiple of the average mesh size, so it must be positive and generally should be a decimal value between zero and one. The splines will begin and end at the chose
