Improve Land Desktop with VBA, why not?

Dear all,

I think that Land Desktop (Civil Design and Civil Survey) is very powerful. I`m using it for highway engineering and i found that there are some of its features should be improved and enhanced by programming. And i`m prefer VBA. At the moment i`m studying how to export the results from Land Desktop to MS Excel. Secondly, a big problem is that with only VBA, how can calculate the fill work in Rehabilitation project? Because it`s clear that Land Desktop is very good for a new design project, but rehabilitation project or Improvement ones@

I wuold be greatly appreciated any comments and solutions for the 2 above problems!

Best regards,

Quang Huan
