### SUDA Tip: Shallow Nodes

Written By: Robert Garrett Sometimes, when we model nodes in SUDA whose minimum depth is very shallow, we are surprised to see that the depth is not what we expected. For example, the inlet shown below should have a relatively small minimum depth of 2.33 ft. But, when we place it, the depth looks too […]

### SUDA Tip: How to Configure a Single Structure Which Contains Two Independent Grates

Written by Robert Garrett In a roadway with a center barrier, we often use storm drain inlets like this one. This type of structure presents a unique challenge for producing a 3D model representing the total structure while also allowing surface flow calculations independently for each grate.  Additionally, the elevations of the two grates could be […]

### SUDA Tip – Best Practice for Headwall 3D cells

Written by: Robert Garrett When configuring the 3D cells of head walls for use in SUDA, there are some required construction points to be created in the cell. Alignment Point – a point of construction class and line style of 3 is used to align the 3D cell with the 2D cell used for plan view presentation. […]

### SUDA – Setting node orientation relative to centerline

In the OpenRoads Subsurface Utility tools, the rotation of nodes is always stored internally as an absolute angle. As you can see in the next image, even though the selected node appears to be relative to the red centerline, if you look at the angle manipulator, you can see that the node rotation is stored […]

### SUDA Tip: Editing Utility Profiles

Written by: Robert Garrett When editing profiles for SUDA conduits, the visual feedback provided in the profiles view can be a little confusing. Consider a water line profile as shown below.  The initial profile was generated with an offset from the existing ground terrain.  I want to refine the profile under the roadway to go […]

### OpenRoads Tip: Offset Alignments and Matching Profiles

Written by: Robert Garrett I often get the question: How do I make alignment B exactly match the stationing of alignment A?  Invariably, this question is related to special ditches, whereby the desire is to have the ditch stationing match the center-line stationing. The answer: This is mathematically impossible unless the two alignments are both […]

### SUDA Tip: Best Practice for Creating Pipes Between Nodes

Written by: Robert Garrett I often get the question: Does it matter which direction I create pipes for my drainage or sanitary networks? The simplest answer is: It only matters when connecting to a head wall. The best practice answer is: Always create the pipe in down stream direction, if you know the direction. In the […]
