There are a few problems for us getting the tutorial up to date at the moment. So we will put off the series for a month and hope to resume the series as soon as we could.
The main reason is that we want to finish the Vertical Curve and the cut and fill programs for Version 1, but we are still in the design stage…so that means this can take weeks before we can release them online here. Anyway, this work causes us to have time management issue and we decided that having the programs work well is more important. So.
