BIM Underground is a Windows app divided into four tabs – “pipes and conduits, maintenance holes, vaults and help/links to S.U.E. information”. The objects created are native to Autodesk® AutoCAD® and can be integrated with Autodesk® AutoCAD® Civil 3D® by reference, block etc.
Once a location and/or route has been established by picking points on-screen the dimensions of the object are inserted into the form and 3d objects are created with a button click. The application does not save actual 3d solid objects but instead saves the dimensions entered to allow the user to recreate the exact structure as saved or tweak an existing structure to meet their needs. Saved structure values can be exported to an xml file for importing by another user.
