• GDF File Crashes when Opening (Geopak Drainage)

    Geopak Drainage crashed when attempting to build a recently created network. Now whenever I open the GDF file, Geopak Drainage crashes before it loads. I'm worried that the entire file is unsalvageable. Can anyone help me? The file is attached. It…
  • GEOPAK Drainage - Longitudinal Slope Source Unable to Calculate from Reference PGL

    I have a project with multiple alignments and profiles and the GDF is able to calculate the logitudinal slope source using the reference PGL for all alignments/profiles except for one. Are there some common things to double check within the GDF, GPK…
  • Geopak drainage link vertex

    If I place a vertex in the geopak element ( see below) instead of a generic junction and to pipes to simulate a bend, will the junction losses still be calculated correctly?
  • Geopak crash

    Hi, While working on Geopak software it gets crashed again and again. It gets crashed mostly while creating network, creating profile and updating profile or pipe invert. Due to these crashes I am not able to work properly. Can you please suggest something…
  • Geopak drainage

    Hi, Is there any command in Geopak drainage to delete all the nodes in one go ? Or we have to delete them one by one by selecting "delete node" option? Any idea?
  • SUDA and Geopak Drainage - Import Process

    Hello, Does anyone have experience applying importing a Geopak Drainage design to SUDA? My initial thought was rather than using the StormCAD inlet, we would have to create the drainage nodes (structures- inlets, MH, etc) in the catalog in order to…
  • Geopak Drainage error

    I've made a final TIN file and am working to get drainage areas for catch basins. This is using TN DOT workflow and when I go to Delineate Watershed I get the following error: Minimum Descent Ridge Loop = 101 Exceeded There are a few spots within…
  • GEOPAK Drainage - Not Saving Node Information

    When editing my Node Configuration properties, some of the information is not saving. It will save information such as location, node type and node bottom, but after going to different nodes or closing out of the program it will forget saved information…
  • Geopak Drainage - Detention Pond Control Outlet Structures

    Is it possible to add weir or orifice structures in Geopak Drainage? Checked the routing tool but it doesn't appear that it's possible. Thanks. UPDATE: http://www.extranet.vdot.state.va.us/locdes/geopak/vdot_drainage_2004ed_stu_trn007630-1-0002…
  • Using Geopak Drainage modeling ditch and drop inlet system, discharge calculated by model is higher than it should be.

    We are modeling some median ditches drain to drop inlet then drains out to the roadside ditch via a pipe. To verify the ditches have enough capacity, we link drainage areas to the ditch beginnings. In the case of two ditches flowing into one drop inlet…
  • How do I export from SUDA to Geopak Drainage?

    Hello, I am trying to export from SUDA to Geopak Drainage to create profiles with HGLs and existing ground, and cant really figure out how to do the export. Please advise. Thanks, Jeff
  • Geopak Drainage Error Computing output for a network with Pipe-Arch

    I am trying to design a storm drain network in an area with limited cover. When I try to use the "Pipe-Arch" option, Geopak reports an error. The same network runs just fine when using circular pipe or box culvert or elliptical pipe. I checked the drainage…
  • Geopak Drainage - Adding a node

    New to this and doing some informal training. Project is setup (I think) and trying to add a node. When placing it manually, it appears, then disappears. Message CEnter error reads "Level with ID : '521' Not found. Using default. Got one node to stay…
  • Geopak Drainage profiles not saving

    I'm working on a project with several pipe networks that all run correctly. I've create drainage profiles for each network, plotted them with no issue and the HGL's all look good. see attached. I save the project and when I come back into the project…
  • Geopak Drainage unable to calculate tin elevation, but DTM Height/Slope Analysis works fine. Thus .tin exists and in the correct place. Any ideas?

    I'm trying to place nodes using GP Drainage. I am new user, so this may be a simple fix. I'm trying to reference my .tin for elevations, but when I place my node it says "unable to compute TIN elevations". I know my .tin exists and is in the correct location…
  • Geopak Drainage - Create drainage structure schedule

    I am using geopak drainage and have proposed pipes and catch-basins/inlets. How can I create a drainage structure schedule using geopak or something close to it? Thanks
  • GeoPak Drainage Pipe Line Styles

    Hi! I'm running a proposed stormwater drainage system within GeoPak Drainage that connects to an existing system, so I'm modeling proposed and existing pipes. We have different line styles for proposed (arrow style) and existing (dashed line style)…
  • Geopak Drainage - Hydraulic Grade Lines

    In my network profile I'm seeing what I believe are irregularities in the HGL of my laterals. For my network, my design is utilizing a trunkline running down one side of the road with six inlets on the opposite side connected to the trunkline with laterals…
  • Geopak Drainage - Inlet Station and offset

    Our drainage design group is wondering if there's a way to lock both Station and Offset in the Inlet "Location" box. Roadway is planning on moving all of the chains several feet due to some datum issue and would hate to move all of the inlets one by one…
  • Geopak Drainage - Building/Designing Network Issues

    I am having several issues that I think are related - When I build a network, I am getting the "unable to build topology" error. If I delete one link and then re add it, the entire system will come up. Then, I will get the message that the network was…
  • Geopak Drainage - Incorrect Junction Inverts

    Hello, I'm currently setting up a profile with known pipe and manhole inverts. I'm able to set the pipe inverts in the link configuration box, however the manholes inverts are being shown at Elev 0.00. How can I set the inverts of the structures manually…
  • Geopak Drainage

    I am working on a roadway drainage project and have encountered a problem with the Geopak Drainage profile. I set the link elevations as I normally do, then when everything was set I created a profile. I plotted the profile and everything looked fine…
  • Geopak Drainage ~ Edit Drainage Profile dialog

    Why is the Link Profile tab inaccessible when the Project to Chain option is toggle ON? I like to edit the pipes with that dialog and this feature is annoying. Any input?
  • Geopak Drainage ~ Node width in profiles

    Some of the node widths on my Geopak Drainage profiles do not seem to be correct. The first and last node of all profiles are drawn to half the width they should be. The pipes are connected in plan view to pipe connection points on the side of the…
