With my electrical CAD and design background I was called upon to find an
acceptable route for the electrical cable tray through a very busy and complex
tank structure while it was still in the design phase. In addition to
finding the route I needed to create an Electrical Cable Plan, Bill of Materials
and coordinate with both the structural and piping engineers.
Looking at the task I decided that I needed to see the problem in 3D. The piping
was already drawing in 3D but the structural elements were not. I placed
structural parts in their correct location and elevation, overlay-ed the piping
and was able to find a route that would balance both the cost of cable tray and
the cost of conduit runs. I drew the tray in
3D using AutoCAD 2002 to make sure
it would fit and gave it to the piping engineer to overlay on his drawing to
eliminate future interferences if there were any future piping changes. I worked with the structural engineer to modify structural pipe support
drawings to support the new cable tray before they were sent to the fabrication
shop.
I created the Electrical Cable Plan by flattening the 3D drawing to
2D. Since I had the cable tray in 3D I used it to create a tray detail with the
Bill of Materials on an
Electrical Details Sheet. Photo2 &
