Civil 3D corridor baseline based on Feature Line export to sensor

Trimble Link is capable of no question exporting these kind of baselines !
Leica Infrastructure Link displays an error message and no export takes place.
Leica X-Change is discontinued. Last version was for Civil 3D 2016. This feature is available from v2017.

Civil 3D Trimble Link Road export tip. Feature lines unchecked. Point empty coding.

When exporting a Civil 3D Corridor to a Trimble sensor using Trimble Link the apropriate Corridor Surfaces must have already been created.
But no Cross Sections will be exported if Surface is created through Links that the Feature Lines at the two edges of each Link are not checked !
This also means that uncoded points can not create a Trimble Link exportable surface !

 

Leica Infrastructure Link discontinued ?

It is July. March was the release date of Civil 3D 2018. There is no Leica Infrastructure Link for it. Maybe discontinued ?

No. Released at the first week of August. Nothing new. Same problems. Same limitations. Just working with C3D2018. Simple DLL recompilation using latest references.

Leica Infrastructure Link multiple baseline corridor export

In case a Corridor consists of more than one Baselines based on different Alignments then all Feature Lines checked in whatever Baseline are exported but only the first Baseline Alignment is exported ! All other are ignored ! Finally only one Layer is created for the entire Corridor.
So it is not possible to set the appropriate Centerline when in RoadRunner.

X-Change was capable of producing multiple Layers.

So it is crucial to work only with X-Change and up to Civil 3D 2016
or
create mutiple Corridors, one for each Baseline
or
do multiple HeXML exports having checked only one Baseline per session but it does not work

Leica vs Trimble software support

Trimble has published its Civil 3D 2017 export/import set of applications since the first days autodesk announced it.
September ends and Leica has not published its X-Change sets of applications although there are already Infrastructure and Building Links for 2017 editions months ago.
