Breaking Changes in MiTS 3

‘Project Parameters’ is Now Called ‘Project Settings’ in MiTS 3 #

As part of ongoing improvements in MiTS 3, the section previously known as Project Parameters in MiTS 2 has been renamed to Project Settings.

‘Program Settings’ is Now Called ‘Machine Settings’ in MiTS 3 #

In MiTS 3, the section previously known as ‘Program Settings’ has been renamed to ‘Machine Settings’ for better clarity. Settings remain specific to the user’s device.

CCF Parameter Setting in MiTS 2 vs MiTS 3 #

In MiTS 3, the CCF inclusion is by default set to “Include”. If a user has set CCF values to “NotInclude” in MiTS 2, the parameter setting from MiTS 2 will not be preserved when the user opens the same project file in MiTS 3. Hence, there will be changes in analysis under Storm Water Module and MSMA Module, since CCF Inclusion are set by default to be true in MiTS 3. User can change the CCF Inclusion under Project Settings in MiTS 3.

MiTS 3 Resets Custom IDF Coefficient from MiTS 2 #

When opening a MiTS 2 project file in MiTS 3, any user-defined MSMA 2 IDF coefficient that are previously configured in the Drain Module will not be retained. In MiTS 3, it will automatically reset the IDF Fitting Constant and CCF values to the default values in the guidelines regardless of the custom values that users have set in MiTS 2. Users may refer to these guidelines:

1. IDF Coefficients: MSMA 2nd Edition
2. CCF Values (Peninsular Malaysia): Hydrological Procedure 1 (Revised and Updated 2015)
3. CCF Values (Sabah and Sarawak): Hydrological Procedure 26 – Estimation of Design Rainstorm in Sabah and Sarawak (Revised and Updated 2018)

To customize the IDF Coefficient in the Storm Water Module, user can manually define the values inside Project Settings or under Properties Tab:

Verge Slope Now Independent in MiTS 3 #

MiTS 3 verge slope calculation is similar in MiTS 2 for determining the verge slope ratio. It will follow the value you set in the Properties tab in the RHS panel or the Project Settings. Note that the method “the verge slope is dependent on the shoulder” is removed. Therefore, Verge Slope is now always independent of any road width entities, (e.g.: carriageway, shoulder, etc). You may refer blogppost on Calculation of Verge Slope Ratio for further understanding.

V-Drain is now always independent of berm in MiTS 3 #

Say if you wanted to revise an old slope design project (that was created using an older version of MiTS 2) in MiTS 3, you might notice V-Drain in MiTS 3 is always independent of berm, unlike old version of MITS 2, where V-Drain can be made included in the berm.

You will need to manually recreate V-Drain in MiTS 3. Note that this only affects very old project files, which are created in older versions of MiTS 2, so newer files created directly in MiTS 3 or imported from the latest MiTS 2 version should be fine.

In MiTS 3, you can configure your slope entities (e.g.: slope, berm and berm drain) to your preferences and create multiple slope templates to align with your design requirements. You can refer to Slope Template for further understanding.

Invert Level Settings in MiTS 3 for Utility Modules #

When you are upgrading from an old version of MiTS 2, the Invert Level settings from the older version may not be carried over automatically to MiTS 3, particularly for the following modules:

1. Drainage Module
2. Sewerage Module
3. Water Reticulation Module

Therefore, to ensure accurate modelling and analysis, you may need to recheck and reassign the invert level settings manually when you open the old project file in MiTS 3.
