Because it's different from most of our classical architectural academic training and what we have learned and where are skills with software make doing a set of drawings reasonably comfortable.
I have always make the following statement when presenting Revit to groups and in client presentations that "architects are first to innovate new and creative use of space, implement new construction techniques and use of materials for clients but last to implement technologies to enhance and improve the develop our documentation and presentations in our practice."
That said, it will take several years for the AEC professions to accept and upgrade to building modeling software technology and another year or more to fully implement the features and benefits of parametric database modelers into their practice.
It is the firms willing to explore the richness of building modelers today and seize the opportunity to use software to enhance our design innovation and document coordination who will lead the AEC professions toward delivering better documentation while reducing costly overhead and offering greater service at competitive prices.
