碩士 === 國立中興大學 === 土木工程學系所 === 103 === With the advances of technology, civil engineering industry from the original 2D drawings and 3D building information modeling (BIM). In the current engineering contract structure, procedures mainly made by architects, following completion of the design, Construction Contractors check design drawing and then build BIM. Most the architect build the 3d model prefer using Sketchup software, but it is too weak to build the curved surface. When the building involve in curved surface , architects often using the software(Rhinoceros),which is extraordinarily good at building the curved surface to the 3d model, as well draw 2d model (AutoCAD) . This research creates A Point To Mass Generator as P2M, using Revit as platform. P2M including writing python programs, information extract from 3D geometric model, and computing the curved surface points. The information read is divided into two : (A) Using the architect by rhino drawn model 3D model file, reading 3d data parsing, get point coordinate information , and build a massing on the Revit. (B) For example to building parking climbing lane module ,The lane parameters input to P2M are calculated for lane occupancy punctuation and automatic building massing, and consider the lane in the corners of Super-elevation. P2M to reduce the conversion of information will result in graphics conversion error and the efficiency of the problem , and improve building difficult surface efficiency. At last, PointToMass modeling the result in Revit.
