  • Patent number: 10606964
    Abstract: A method, system, apparatus, and computer program products provides the ability to dynamically define and generate inlet spacing along a road in a building information model (BIM) computer aided design (CAD) three dimensional (3D) model. A representation of a road is acquired in the BIM CAD 3D model, wherein the representation includes a geometry. An inlet spacing is defined for the road. Inlet locations for inlets are determined based on the inlet spacing. A determination is made regarding whether the inlet spacing and inlets satisfy design rules for the road. When the inlet spacing and/or inlets fail to satisfy the design rules, a different inlet spacing is selected from a group of preset integers, and the process repeats until the design rules are satisfied.
