[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] Those skilled in the art will appreciate that embodiments of the present invention may be provided as methods, systems, or computer program products. Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0041] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatus.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] The existing 3D design modeling has high accuracy requirements, which means high hardware performance requirements. In addition, there is an inherent modeling order in multi-professional design modeling. The design modeling process has many interference factors such as capture and vision due to the large number of point, line and surface elements of the reference facilities. The present invention uses the overall planned simple system layer as the modeling constraint layer, which can reduce the hardware performance requirements to a certain extent, optimize the multi-professional modeling order, reduce the interference elements of design modeling, greatly reduce the difficulty of 3D design and improve design efficiency.

[0044] In the present invention, the architectural design modeling method based on three-dimensional design of the present invention is to perform design modeling based on a BIM design platform. For example, design modeling can be performed based on a Bentley series of software, but the method of this patent is not limited to this series of design modeling platforms.

[0045] Figure 1 is a flow chart of a method for building design modeling based on three-dimensional design according to an embodiment of the present invention. Figure 1 As shown, in one embodiment of the present invention, the architectural design modeling method based on three-dimensional design of the present invention includes steps S101 to S104.

[0046] Step S101, establishing the axis grid of building facilities.

[0047] In the present invention, this step establishes a reference axis grid based on the integrated, multi-system building facilities as the overall modeling reference, and the size of the axis grid is established according to the design requirements.

[0048] Figure 2 This is a schematic diagram of an axis grid of an optional embodiment of the present invention. Figure 2 A 4m×4m building facility axis grid was established.

[0049] Step S102: establishing a modeling constraint boundary surface based on the axis grid and system space requirements, wherein the modeling constraint boundary surface is used to divide the overall space within the building range.

[0050] In the present invention, this step makes an approximated finite boundary surface according to the spatial requirements of each system, that is, a modeling constraint boundary surface, and divides the overall space within the building range by the modeling constraint boundary surface, so as to plan the space layout in advance for subsequent design. The present invention establishes a modeling constraint boundary surface based on the axis grid, making the boundary surface neater and more orderly. The present invention establishes a constraint boundary surface based on the boundary requirements of each system, making the reference boundary more reasonable and accurate.

[0051] In one embodiment of the present invention, the system space requirements specifically include: space requirements for floors, structures, pipelines, equipment, passages, bridges, and safety distances.

[0052] In one embodiment of the present invention, the modeling constraint boundary surface is perpendicular or parallel to the axis grid. The number of modeling constraint boundary surfaces is as small as possible.

[0053] In one embodiment of the present invention, the modeling constraint boundary surface is an auxiliary structural layer, which is displayed transparently and can be displayed or hidden during modeling, serving as a modeling auxiliary boundary.

[0054] The present invention makes approximate finite boundary surfaces according to the system space requirements such as floors, structures, pipelines, equipment, passages, bridges, safety distances, etc. The modeling constraint boundary surfaces are parallel or perpendicular to the axis grid plane as much as possible, and the total number of boundaries is as small as possible. The overall space within the building is divided by the boundary surfaces, and the space layout is planned in advance for subsequent design. The boundary surface needs to be an auxiliary structural layer, displayed transparently, and can be displayed or hidden during modeling as a modeling auxiliary boundary.

[0055] like Figure 3 As shown, in one embodiment of the present invention, the present invention establishes an approximate finite boundary surface based on the boundary requirements such as the building shape and pipeline planning in the system. If there are four main structural columns at the four corners of the steel structure, the boundary surface of the structural columns is generated, and when arranging other facilities, the layer of the boundary surface of these structural columns needs to be avoided. The design method of other facility layers is similar. Figure 3 All layers parallel to the axis grid are floors, and the layer thickness and height are designed according to the structural requirements. The layers outside the 1 axis are pipeline layout layers, and the layer thickness and shape are designed according to the pipe diameter and pipeline routing. The specific design of each layer needs to be defined by yourself, and there is no fixed rule.

[0056] Step S103: setting a system layer according to the modeling constraint boundary surface, wherein the system layer is established based on at least two of the modeling constraint boundary surfaces.

[0057] In one embodiment of the present invention, the system layer specifically includes: a structure layer, a pipeline layer, an equipment layer, a channel layer and a bridge layer.

[0058] The present invention develops a system layer definition function in the three-dimensional design software. Every two or more modeling constraint boundary surfaces can form a system layer, and its system layer attributes are defined according to different system requirements. It can also be distinguished by easily identifiable attributes such as its color. The attribute information can be customized and does not affect the subsequent design modeling as a whole, such as the structure layer, pipeline layer, equipment layer, channel layer, bridge layer, etc. The system layer can be defined multiple times according to the design requirements. The system layer is a construction auxiliary layer that can be hidden and displayed.

[0059] like Figure 4 As shown, the present invention performs system-level customization based on modeling constraint boundary surfaces, such as Figure 4 The building structure layer and pipeline layer in the design can be directly read from the attributes during multi-disciplinary design to achieve design collaboration among multiple disciplines and designers.

[0060] The present invention uses a system layer formed by simple elements instead of refined modeling of a large number of elements as a reference layer, thereby alleviating the high hardware load problem caused by the refinement of three-dimensional design during three-dimensional design modeling, and reducing the design modeling capture and visual interference problems caused by multi-system references in three-dimensional design.

[0061] Step S104, completing model building by performing design modeling in the system layer.

[0062] In the present invention, by setting up the system layer, different design professions and designers can refer to the axis network and system layer, perform design modeling within their system layer, and simultaneously complete the spatial layout, design and modeling of each system, reduce design cross-errors, and improve the quality and efficiency of three-dimensional design.

[0063] like Figure 5 As shown, the present invention refers to the axis grid and system constraint layer, and each discipline completes the design modeling, such as arranging structural columns at the four corners of the axis grid, arranging beams and plates on the floors, and arranging pipes on the pipe layer. Among them, the column, beam, and plate models are selected according to the force calculation of the structure discipline, and the pipe size and route are designed and arranged according to the requirements of the process discipline.

[0064] In one embodiment of the present invention, the modeling constraint boundary surface and the system layer are both auxiliary structural layers.

[0065] In one embodiment of the present invention, the architectural design modeling method based on three-dimensional design of the present invention further includes:

[0066] After the design modeling is completed, the auxiliary structural layer is hidden.

[0067] In one embodiment of the present invention, the architectural design modeling method based on three-dimensional design of the present invention further includes:

[0068] After hiding the auxiliary structural layer, each professional design is checked and cut out after verification.

[0069] In the present invention, after completing the professional design modeling, the system constraint layer is hidden, such as Figure 6 As shown, check that all professional designs are correct and then cut and draw the drawing.

[0070] It can be seen from the above embodiments that the architectural design modeling method based on three-dimensional design of the present invention achieves at least the following beneficial effects:

[0071] Effect 1: The overall system level is pre-planned, making the design layout more orderly and reasonable, and reducing the difficulty of spatial imagination;

[0072] Effect 2: Optimize the design time overlap problem caused by the inherent sequence of conventional multi-disciplinary and multi-system design modeling, carry out design modeling simultaneously, save design modeling time, improve design modeling efficiency, and reduce the difficulty of 3D design;

[0073] Effect 3: Using simple boundary layers and system layers instead of refined models as the basis for space layout, reducing the high-performance requirements of 3D design for hardware facilities such as computers, speeding up the response rate of 3D modeling, reducing hardware load jams and crashes caused by refined modeling design, and reducing the difficulty and cost of promoting 3D design;

[0074] Effect 4: Simple boundary layer and system layer references have fewer point, line and surface elements than refined modeling, reducing interference factors such as vision and capture in system internal modeling, and improving design modeling efficiency and accuracy;

[0075] Effect 5: Before multiple design disciplines start designing, a unified reference system (boundary layer and system layer) is provided to reduce design errors caused by design intersections and reduce the difficulty of design modeling and assembly.

[0076] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
