In this paper we have presented a general, overview type of approach to geometric modeling with BRL-CAD. We outlined the important link between the intended application and the overall requirements of the geometric model. We looked at an approach to effective BRL-CAD database management, based on the design of the database structure itself. We also presented some standard naming conventions that have proven effective for armored systems. Finally, we discussed the philosophy of geometric modeling and presented a general plan to accomplish any modeling project.
