Patent number: 10606964Abstract: 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.Type: GrantFiled: June 20, 2017Date of Patent: March 31, 2020Assignee: AUTODESK, INC.Inventors: Xiaoming Fei, Weihua Zhong, Lei Hua, Tianzuo Zhou, Jianwen Huang, Zeyi Xia, Yimeng He
