Trimble Business Center : Incapable of exporting corridor with variable SideSlope through RXL templates.

There are some cases that a corridor can not be exported correctly or at all through RXL templates.

Correct surface

One of this is when a template has a Side Slope with a varying slope through eg a table with no surface to catch assigned.

It simply fails showing an error message. Complete failure. No file at all.

 

 

Error message

 

At a similar case where a surface is not assigned but the SideSlope is constant then the exported RXL is a complete mess. Added lines from nowhere and wrong SideSlopes . A now warning at all RXL file full of serious mistakes !!!

Another case is when a template ends either with a varied SideSlope or with an element such as Offset/Elevation that is based on a target or a table to set its exact width, height or slope.

In this case the exported templates do not reflect the desired form.

The exported template is broken into templates adjusted at each horizontal and vertical point of intersection of the hinge point. The slope that the original template had at this stationing is kept and applied constantly throughout until the next template.

Finally you get an RXL file full of errors, no warning at all !!!

Red for wrong daylights. Green for correct. Yellow for POIs.

So it is impossible to export through RXL templates a variable Side Slope either in the form of a SideSlope/CutFill or just in the form of line.

Such a frustrating limitation!

The only semi workaround i have found is to do the export through "RXL road export from surface".

Trimble Business Center : RXL road exporter from surface : Critical parameter for curved alignments

Exported Corridor Surface can have a wrong form like the below.

Watch the triangles top right.

 

This is happening only at curved alignments when an exporting parameter is not set to the proper value.

Here is what to do.

Select Export.

At the Export window select RXL road exporter by surface.

At the settings set parameter "Adjust for arc/chord offset:" Yes

 

Now the exported RXL is correct.

 

Trimble Business Center v5.20 : Corridor : Slope/Elevation direction tip

I created a template with a Slope/Elevation for the left side. Desired slope direction was towards the left side no further actions required.

I mirrored it to the right. And the Slope/Elevation direction was towards left though it should be to the right.

I got almost crazy trying to find what was going on.

 

Finally i found the solution.

By default the slope is towards the left side. To set it to the right the point that is attached to must have a positive offset from its previous one! If it is vertical a 0.00001 value is enough to turn the set the direction to the right.

 

Trimble should mention this at the manual. I lost 7 hours from my work trying to find a solution.

 

This problem was reported to a Trimble forum and was answered by Alan Sharp. The solution was the same. I should have checked there from the very first time.
