OpenRoads showing an error when trying to edit Catchment

Andrew Garrett — Tue, 22 Aug 2023 11:29:12 GMT

I started working on this project approximately a year ago with a previous ORD release and have now come back to it after our CADD Manager upgraded me to ORD CE - 2022 Release 3 (10.12.02.4). I went to adjust my Catchment Areas and received the attached error.

The Catchment is not locked, but I am unable to move or delete some of the vertices, while other vertices behave as expected. Is this something caused by the change in ORD version or is there another solution?

Converting between SUDA and Legacy Geopak

Current Version: Power GEOPAK V8i (SS10)

I am in the process of starting a new drainage design and am trying to determine the most efficient workflow in order to provide the following:

- 2D Drainage Layout

- Inlet and Pipe Computations

- Drainage Profile and Description Sheets

- 3D Drainage model (Physical Model only)

My initial thought was to create the design using SUDA and then export to Legacy Geopak in order to produce Drainage Profile and Description Sheets like I've done previously, but it seems that the export is fairly sloppy and loses a good bit of information along the way. Since I'm only really interested in the Physical components of the 3D model (for utility conflicts) and not concerned if the computations come from Legacy Geopak or SUDA Flex Tables, would it make more sense to do the design in Legacy Geopak (so it's easier to produce profiles and descriptions) and then export to SUDA for the 3D model?

Thanks!

"ghost" drainage area can't be remove

When I try to run my base analysis scenario, I get the following error message:

44008 "Base Analysis" "Catchment" "338" "1" (N/A) "The catchment is active but there is no outflow element specified, or the element is invalid or deleted. " Hydraulic Results

I can't find this catchment in the 2D/3D model and it does not exist in the explorer either. Is there a way to delete this "ghost" catchment?

Modify catchment created by picking points.

Is it possible to add points to a catchment area shape? Using the insert or delete point tool seems to work at first, but if another point is moved on the catchment the new point previously created is lost or the deleted point is regenerated.

Manually set Rainfall Intensity for Inlet Computations in OpenRoads Designer

Andrew Garrett — Mon, 15 Nov 2021 14:26:22 GMT

Hello - I'm a new ORD user trying to get familiar with the VDOT - Civil workspace. In Virginia, for certain roadway classifications, the VDM requires the use of an intensity of 4 in/hr for inlet computations (Spread Width). Previously, in Geopak, I was able to select a box within the preferences of the drainage design file that allowed the user to set a maximum intensity value for inlet computations. Is there a similar feature in ORD that I am missing? Alternatively, is there a work around to have the inlet computations use a different intensity than the capacity computations? Seems like the work around I'm finding is creating user defined Storm data that outputs a 4 in/hr intensity and checking the "Use Local Rainfall" box in the catchment tab before running the scenario so the intensity computes correctly. I haven't tried this yet as that seems too long winded to be the solution here but if that's the case then I'll move forward with that.

Thanks

OpenRoads Roadside Channel Analysis

Andrew Garrett — Mon, 22 Mar 2021 12:47:50 GMT

Hello,

I'm new to ORD and was looking for some training on Roadside Ditch Analysis. Bentley's LEARNserver has training videos and a PDF (Placing a Ditch and Culvert Network) which is great but, at the beginning of the training PDF, it specifies that there are two workflows for Roadside Ditches. The first is Terrain with Ditches (or invert at Grade) and the second is Terrain without Ditches (or invert Below Grade). I anticipate our modeling team to include the Ditch Grading when they are creating the Proposed Terrain model, but this training PDF specifically explains that it focuses on the Terrain without Ditches Workflow i.e. if the Ditches aren't modeled. Is anyone familiar enough with this to explain if it's a similar process for Analyzing Ditches that are already present in the Terrain model and/or point me in the direction of a training PDF/Video that explains the other workflow not included in the LEARNserver?

Is it as simple as using cross section nodes and placing them at the inverts of the modeled Ditch rather than relying on the upstream/downstream nodes to create the Ditch/Inverts?

Thanks!
