Offset Slope "could not compute"

When I select an alignment to station reference that is coincident with the line to offset it returns “could not compute” if the sampling distance is set to “0”. What could cause this?

I think I need the lines to see what it is doing for you as I have tried to recreate what I think you are doing and it works each time for me. Can you email me a VCL of the lines in question so that I can take a look at what is happening

I also do not see you in our TML management system which likely means that the version of the command you are running is old and out of date - so we should try and get you updated first to see if that fixes the issue as these types of error came up when we first adopted the commands from Trimble and they have we believe been addressed over the past year.
