Remarkably Easy-To-Use 3D Engineering Design Software

  • Speed design with revolutionary drag and drop options for selecting headwalls and endwalls
  • Delineate drainage and ponding areas
  • Calculate runoff from surface models
  • Size culverts and place at low points
  • Fit headwalls from Headwall Library using solid modeling
  • Grade surfaces for both upstream and downstream designs
  • Move culverts and headwalls to new locations with full dtm restoration
  • Choose from multiple barrel options
  • Integrate easily into Carlson Civil Suite, AutoCAD and Microstation


  • P3D is multithreaded and performance will increase with core count.
  • P3D is 64bit and will use all available RAM available to support large models.
  • P3D uses advanced 3D shaders and performance will increase with graphics cards that process these faster.
