Abstract

The invention discloses a BIM parametric modeling method and device based on Dynamo. The method comprises the steps of conducting component division on roads or bridges provided by a project construction drawing; extracting position coordinate information and cross section contour parameter information of the component into an EXCEL table; reading position coordinate information of all componentsin the EXCEL table to generate a space entity model of all coordinate points; sequentially connecting the coordinate points of all the components into a line to obtain a fitted center line of the roador the bridge; according to the position information corresponding to the cross sections of all the components in the EXCEL table, obtaining reference position information of the cross sections of all the components through conversion; reading cross section contour parameter information in the EXCEL table, and loading the cross section contour parameter information into a reference position pointof a corresponding component; and driving the cross section profile to scan along the center line to obtain a solid model of the corresponding road or bridge. According to the invention, rapid parametric modeling can be realized, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of road and bridge modeling, in particular to a Dynamo-based BIM parametric modeling method and device. Background technique [0002] BIM technology refers to the visual digital building model (Building Information Modeling, referred to as BIM) constructed based on advanced 3D digital design solutions. BIM technology is applied to the design stage of bridges, roads, tunnels, etc., and can quickly model, model calculation, drawing output, engineering quantity statistics, collaborative design, digital information construction, construction simulation, and create a 3D digital model containing complete engineering information. The realization is completely consistent with the construction site. Dynamo is an efficient computer-aided design tool in parametric architectural design software and an open source plug-in based on Autodesk Dynamo information management platform. It uses a computational design method an...
