- All common edges are defined as hinge lines. (Left click on the section edge and then under File menu you will see the option to toggle on the hinge option)
- Use the option to add in extra points along section lines. Ezigrade needs points along the line that are in both sections to match edges.
- At present all sections need to be variable grade that are joined together. (or all planar) This will be relaxed in a future release
Please remember that the drain(/bank) routines also allow you to achieve similar outcomes.
