Issue: #

How can we design berm drains with drain types such as V-Drain, Box Drain, Trapezoid, and Udrain?

Solution: #

With the Slope Template Configuration feature available under the Platform Editor, user can modify the berm drains dimension to follow the desired shapes.

Steps in modifying berm drain types: #

1. Input > Select Platform ‘X’ > Double click on Platform ‘X’ or Under Spread Input, click on ‘…’ under the Height column > Platform Editor will appear.

2. Click on the ‘Edit’ button under the Slope Template column > Create a new template by clicking the ‘Add’ button under the Slope Templates section.

3. Under the Slope Configuration section, opt based on the nature of your slope.

4. The slope sets should be opted for by the user according to how the slope generation should be;

• Initial, non-repeating – If the slope configuration needs to be unique and controlled for a particular number of tiers.

• Final, cyclic – If the slope configuration needs to be repetitive for all tiers.

5. To apply berm drains for the slope, add Slope Line Type: Drain under the Slope Set Configuration section.

Click ‘+’ Sign > Click Drain > Click OK

For the fill slope, the drain should be located between the Slope and Berm under the Slope Set Configuration. So, remove the berm first and add the Drain. Then, we can add the berm once again as per below.

As for the cut slope, the drain is located after the Slope and Berm. Hence, user can simply add the BermDrain without making any other alterations to the default arrangement under the Slope Set Configuration.

Note: For Slope, BermDrains, and Berms configuration, user needs to key in the values following the restrictions below;

• PlanLength and MaxHeight should only be of positive values.

• SlopeAngle should be between 0 to 90 degrees.

• For Slope and BermDrain, there is a column for PointDirection which consists of Up and Down options. 
  • Default direction for Cut is Up
  • Default direction for Fill is Down

Drain Type 1: V-Drain #
