I'm working for a contractor who builds about 500 houses a year. we build mostly project based - anything above 20 to keep transportation costs to a minimum. This means many models are used more than a few times.
Our details are still AutoCAD, and every model has to perfectly comply with these details. We extract construction drawings from the model, and the goal is to use the model as an exact blueprint for the factories that make our prefab walls and floor segments.
So my question is, what level of detail/realism does everyone put into the model? How does everyone feel about the idea that spending more time on the details early on saves time and frustration during the pre-construction process? How many of you use the third dimension in crosslevel families to make floorplans and construction drawings 'talk' to each other and detect construction problems during the design stage?
