  • 2.55. Add Fixed Cross Section
Extend Clip Options Dialog
These options are applied when a fixed section is moved horizontally or vertically by an alignment change. The last leg in the fixed section is automatically extended until it intersects ground and/or clipped when it cross ground.

Maximum extension distance
This is the extension distance ground. It is measured from the start of the last leg (closing leg).
Simplification tolerance
This tolerance is used to remove co-linear points on the last leg before it is extended.
Auto correct closing
Auto correction is only applied if Extend/Clip (above) fails. The example below illustrates a situation where Auto correct is applied. In this case, the specified cut/fill slopes are applied.
