Revit preprocessing method based on BIM model

Abstract

The invention provides a Revit preprocessing method based on a BIM model, and the method comprises the following steps: selecting a project sample plate, and creating a blank sample plate; establishing an elevation and an axis network on the blank sample plate; importing a CAD topographic map and an indoor planar graph, and loading RED-Rev by positioning an original point; performing outdoor siteterrain modeling; carrying out building modeling and indoor component creation, wherein internal components of the building are divided into a movable class and a non-movable class; carrying out modelfinishing and rendering; enabling the model to interact with other platforms; and judging whether the modeled building model needs secondary development or not, and if so, entering building modelingand indoor component creation. According to the invention, earlier-stage preprocessing and manufacturing of the BIM model are performed through the RED-Rev software to enable processing of the three-dimensional model to be dynamic, correlation is carried out between the three-dimensional model and all components, the model is analyzed through data obtained through measurement or calculation, the three-dimensional model preprocessing capacity is improved, the modeling efficiency is improved, and the difference between a model finished product and the actual situation is small.

Description

technical field [0001] The invention relates to a preprocessing method of a three-dimensional model, in particular to a RED-Rev preprocessing method based on a BIM model. Background technique [0002] The processing of 3D models in the prior art belongs to static processing, the interrelationship between various components is poor, and the model design lacks intuitive data such as parameters, resulting in poor preprocessing ability, slow modeling speed, and There is a large gap between the finished product and the actual one. [0003] Overview: BIM RED-Rev is a parametric modeling design software. The design of components has practical significance. The creation of components needs to be parametrically designed according to actual project requirements: [0004] 1. Dynamic and related: All parts in RED-Rev are dynamic and organic, that is, changes in one place and changes in other places. For example, the attachment relationship between the wall and the window, the roof and...

Problems solved by technology

[0006] 3. Constraints are formed between components in RED-Rev, not ordinary 3D models. For example, doors and windows can only be placed on walls, and stairs have bottom constraints and top constraints, so as to form up and down stairs, etc.
