Abstract

The present application discloses a front-end-based three-dimensional model section surface geometry analysis method and device, the method is: based on the front-end three-dimensional model, multiple collision surfaces are generated; based on multiple line segments obtained by the collision between the three-dimensional model and the target collision surface, multiple line segment groups are generated; based on the multiple line segment groups, multiple polygons are generated; the attribute information of the multiple polygons is determined; based on the attribute information of the target polygons that meet the target conditions among the multiple polygons, the geometric measurement of the target geometric area is determined. The method uses the multiple line segments obtained by the collision between the target collision surface and the three-dimensional model to obtain multiple polygons and corresponding attribute information, and combines the attribute information of the multiple polygons to determine the geometric measurement of the target geometric area, so as to realize the digital analysis of any section surface of the three-dimensional model at the front end, accurately identify the type and geometric measurement of the target geometric area, and thus effectively realize the front-end three-dimensional model section surface geometry analysis.
