Abstract
Description
Background Art

Currently, BIM modeling mainly uses Revit software for software modeling, using internal families or self-built families, setting component numbers, size parameters and other model information, and then placing them in the model space. All components need to be manually parameterized and placed. BIM modelers have a large workload, modeling time is long, and errors are difficult to find. For Revit software rapid modeling, its component families still need to be created manually, but the automatic placement of components can be achieved by relying on the capture layer.

[0030] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:
[0031] Figure 1 A schematic diagram of a flow chart of a method for rapid modeling of a building construction structure according to an embodiment of the present invention;
[0032] Figure 2 The present invention is a schematic diagram of a rapid structural modeling system for a building construction project according to an embodiment of the present invention. DETAILED DESCRIPTION
[0033] like Figure 1 As shown, a rapid modeling method for a building construction structure according to an embodiment of the present invention comprises the following steps:
[0034] S1. Obtain the structural drawings of each layer of the two-dimensional formal structural drawings of the building construction project, and make the coordinate systems based on each structural drawing coincide. Specifically:
[0035] According to the number of layers of the formal structural drawings of the building construction project, the formal structural drawings of the building construction project are split according to the number of layers to obtain the structural drawings of each layer. The file format of the formal structural drawings of the building construction project and the file format of the structural drawings of each layer are both in dwg format. The file format of the formal structural drawings of the building construction project can also be set and adjusted according to actual conditions.
[0036] Among them, two-dimensional formal structural drawings of building construction projects can be designed through software such as CAD.
[0037] S2, extracting the edge line of each building structure component from each structural drawing;
[0038] The plurality of building structure components include walls, columns, beams, slabs and openings, and the edge lines of the plurality of building structure components include: edge lines of walls, edge lines of columns, edge lines of beams, edge lines of slabs and edge lines of openings.
[0039] S3. Setting the edges of building structure components of the same size in the same target layer, and adding component information of the corresponding building structure components in each target layer, wherein the component information of the building structure components includes: type, size and material of the building structure components.
[0040] For example, walls of the same size in each structural drawing, such as 300 mm thick walls, are building structural components of the same size. All edge lines of 300 mm thick walls are extracted from each structural drawing and placed on the same target layer. For example, all edge lines of 800×800 mm columns are extracted from each structural drawing and placed on the same target layer, and so on, to obtain multiple target layers.
[0041] Corresponding component information is added in each target layer. For example, in the target layer corresponding to a 300mm thick wall, the added component information is "wall-300mm-concrete grade C40", where "wall" in the component information is the type of building structure component, 300mm is the size of "wall", and concrete grade C40 is the material of "wall"; for example, in the target layer corresponding to an 800×800mm column, the added component information is "column-800×800mm-concrete grade C40", where "column" in the component information is the type of building structure component, 800×800mm is the size of "column", and concrete grade C40 is the material of "column", and so on. Corresponding component information is added in each target layer, and the component information added in each target layer can be set according to actual conditions.
[0042] Moreover, the file name of each target layer can be uniformly set.
[0043] S4. Using 3D modeling software to automatically capture all edges in any target layer, and creating a 3D model corresponding to the components in the target layer according to the component information in the target layer, until a 3D model corresponding to the components in each target layer is created, and a 3D model corresponding to the formal structural drawing of the building construction project is obtained, specifically:
[0044] Link each target layer to each floor plan of the 3D modeling software respectively. Capture a target layer by manually clicking on the lines, or automatically capture all target layers. Automatically load the type and size of the building structure components through the component information added in the target layer. Automatically lay out and model through all the lines of this target layer to create a three-dimensional model corresponding to the building structure components in the target layer, until a three-dimensional model corresponding to the building structure components in each target layer is created, and a three-dimensional model corresponding to the formal structural drawing of the building project is obtained.
[0045] In another embodiment, if the coordinate systems on which each structural drawing is based are not overlapped, each target layer is linked to each floor plan of the three-dimensional modeling software, and all the edges in each target layer are moved to the specified position so that the plane coordinate position of the target layer is consistent with the building positioning in the drawing, and the coordinate systems of all target layers are unified. A target layer can be captured by manually clicking on the lines, or all target layers can be captured automatically. The type and size of the building structure components are automatically loaded through the component information added in the target layer, and all the lines of this target layer are automatically laid out and modeled to create a three-dimensional model corresponding to the building structure components in the target layer, until a three-dimensional model corresponding to the building structure components in each target layer is created, and a three-dimensional model corresponding to the formal structural drawing of the building construction project is obtained.
[0046] Among them, the 3D modeling software is Revit software or 3DMAX software, etc.
