Notes on importing MiTS 1 project into MiTS 2

1.0 Issue:

MiTS 2.0.44.0 onwards won’t be importing road module generated in MiTS 1 into MiTS 2 as Earthworks Platform. This is because the algorithm between these two versions is slightly different which results as per examples below.

Example	MITS 1	MITS 2
Different chainage at intersection	Intersection chainage at CH 709.232	Intersection chainage at CH 709.088
Different elevation at intersection	Road elevation at intersection is 33.161 m	Road elevation at intersection is 33.162 m

The discrepancies shown in the examples above are explained as:

1. Slight difference in road platform generated in MiTS 1 and MiTS 2 because MiTS 2 uses better road platform algorithm.
2. Difference value of imported road vertical alignment and junction between MiTS 1 and MiTS 2 because MiTS 2 uses more accurate algorithm.

2.0 Solution:

To resolve this, users need to fix the verification errors and regenerate the road platform in MiTS 2 to avoid duplicated platforms in Earthworks.
