bug in a corridor surface section?

[joantopo]

Hi.

I have a profile view with a Design Profile (colour red) and Existing terrain (color green).

There are 2 inflection points:

* in station 0+141 design profile is fill and is becoming in cut.

* in station roughly 0+590, design profie is cut and is becoming in fill.

The assembly is using a subassembly: "BasicSideSlopeCutDitch" for slope, but I have canceled the gutter for this subassembly.

If I add two sample lines (particular sample lines) in these stations within the sample line group, I have this:

yelow section is Corridor Surface (from code TOP) section.

green section is Existing terrain (target for corridor).

white polylines, is the theoretical slope properly.

Section view in 0+141 station:

Section view in 0+590 station:

The inflaction point is exactly  0+593.36 but it seems that it also affects to near stations from that station.

The rest of sections are correct, but in inflaction points or quite near, the corridor surface section is wrong. (about its slope).

I attach the DWG file if someone wants to check it.

I have also checked with corridor surface (from code Datum) sections with the same wrong results in these stations.

Thanks in advance.

Sorry for my English.

Add specific corridor frequency lines at those stations and they will then look correct. Right now they are merely reflecting the interpolated surface from the TIN lines that cross at those stations.

Ok.

I thought that the specific corridor frequency lines are added automatically if you added previously new particular sample lines in the sample line group.

I was wrong so I will check the TIN corridor surface next time to avoid this case.
