MiTS 2 users now are able to create a slanting platform by either specifying the elevation by points, or by gradient

Specifying platform elevation by points

Specifying platform elevation by points will be very useful if the platforms are irregular shapes. Unlike MiTS 1, users are restricted to only parallel edges, which may become a hassle for them to readjust the platform shape.

Example is as in the image below, edge C4 – C5 (40 m) is slanted downwards to 35 m at corner C2. To create as such, you can assign 3 points with respective elevation of each of the points.

Steps:

1. Double click the platform.

2. Define the elevation to only 3 points in order to completely specify the platform’s elevation.

3. C4 and C5 are assigned 40 m and 35 m at Corner C2. Then, click OK.

4. The elevation of each corner will be shown in the platform mark, as per image below.

Another way of creating a slanting platform other than specifying the 3 points by elevation is by gradient percentage. To use this feature, “Break” function is involved, as explained in the next section.

Specifying platform elevation by gradient %

Users now can create a slanting platform with a certain gradient by using the Break function in Earthworks. It is also helpful if you are imitating a road slope cross section in Earthworks (ie -2.5% cross section gradient).

Example for slanting platform with 2.0% gradiently goes upward:

1. Create a platform

2. Click “Break”

3. Choose a starting edge (Example C1 > C4 is the starting edge)

4. Click the edge (C1 > C4), starting edge of the first segment is indicated with Blue highlight and purple highlight is the starting edge of the second section.

5. Assign the gradient in the Platform Settings

6. The cut section of the platform can be viewed in the Cut Section Terrain tab

Gradient 1:50 is generated across the platform

Second situation is when road design is created in the Earthworks module and users want to imitate the road cross section. It would be easier if the gradient of the cross section is directly assigned rather than to assign elevation of each of the edge which has to be calculated beforehand.

Example of creating road cross section in Earthworks:

1. Create road platform

2. Click Break

3. Given -2.5% gradient for normal crown. Choose a starting edge (Example C4 > C3 is the starting edge)

4. Click the edge (C4 > C3), starting edge of the first segment is indicated with Blue highlight and purple highlight is the starting edge of the second section.

5. Assign the gradient in the Platform Settings

2.5% upward from C4>C3 and -2.5% from the middle towards the other side of the road

6. Create a cut section across the platform

7. View the cross section in Cut Section Terrain
