[#1]

I want use my corridor where I need it and not use one in certain areas. For a proposed dike. Some places doesn't need to be replace.
So I need a way to use my section on the alignment.
Anybody know where I can find that option?

divide your cooridor into regions and only use the portions needed..

Joe's method will work but you may find that the featurelines created by the corridor span across the gaps between regions.  The way around this problem is to create a Null assembly (an assembly with no subassemblies attached to it) and use that for the regions where you need a gap.

There is another possible issue in that the corridor surfaces will span across the gaps, so your volume calcs may be affected.  There are a few possible solutions for that problem - depending on how the corridor is created.

even when yahide em?

Depends on how you do the calc.  Surface to surface will be affected by the surface hide boundary, but end area or prismoidal calcs may not.
