Problems solved by technology

For the whole building, there are many parts with different clear heights, and we need to measure the clear height of each part again and again, which makes there are more repetitive tasks when analyzing the clear height of a building. And the operation is more cumbersome

Embodiment 1

[0034] refer to figure 1 and figure 2 , a method for automatically generating a building clear height cloud map based on the Revit platform. The operation steps are as follows:

[0035] (1) Pre-operation settings: open the BIM model, start the automatic generation program of the BIM building clear height cloud map, and set the detection accuracy and clear height requirements parameters;

[0036] (2) The user controls and operates the "Select Floor" function module, so that the program automatically obtains the floor elevation information in the Revit project, and analyzes a certain floor according to the user's choice;

[0037] (3) The user controls and operates the "Analyze Clear Height" function module, so that the program analyzes the selected floor, displays various data information on the interactive panel, and also stores various information in the database to obtain point cloud data information ;

[0038] (4) The user controls and operates the "Locate Plan View" fun...

Embodiment 2

[0045] see Figure 1-Figure 9 , a system for automatic generation of building clear height cloud map based on Revit platform, including the following modules:

[0046] User interaction module: The program automatically reads all the floor information in the BIM model and displays it in the WPF form, allowing users to view and select the method; according to the user's needs, set the detection accuracy and minimum clear height value, for different projects Model selection accuracy to meet different clear height requirements;

[0047] Clear height analysis module: For the BIM model, after the user selects a floor and analyzes the clear height, the computer will arrange equally spaced measuring points on the floor of the floor. The spacing of the measuring points is controlled by the precision input by the user. These measuring points A ray will be emitted upward, and an intersection point will be formed when the ray touches the upper floor, beam, and electromechanical pipeline. C...

Abstract

The invention discloses a method and a system for automatically generating a building clear height cloud map based on a Revit platform. Analyze and obtain the clear height data of the building, and obtain the clear height data of the entire floor; generate the clear height cloud map, generate the mass in the BIM model based on the measurement points, and control the mass according to the clear height of the measurement point. The fill color of the section, through the section diagram, you can get the built-in clear height contour map. By extracting the point cloud information in the database, using the WPF+GDI drawing tool to draw a rectangle according to the coordinates of each measurement point, and using the clear height at the measurement point to control the fill color of the rectangle, the external clear height cloud map can be obtained. The invention realizes the rapid and automatic generation of the cloud map of the clear height of the building, effectively improves the efficiency of the designer's clear height analysis, greatly reduces the manpower, cost and time invested in this aspect, and effectively guarantees that the clear height of each position of the building meets the requirements of the building. suitability requirements.

Description

technical field [0001] The invention relates to the technical field of BIM building information model, in particular to a method and system for automatically generating a building clear height cloud map based on a Revit platform. Background technique [0002] BIM technology is another revolution in the construction industry after CAD, and it has important value and promotion effect on the informatization of the entire construction industry. Clearance analysis of the model is an important process during the design phase. However, the calculation of the clearance involves three-dimensional space, the calculation is complex, the engineering volume is large, and it is also very error-prone. At the same time, the designer is based on CAD graphic design, and the clearance reflects a space index. When designing the same building, it is difficult for designers of various disciplines to achieve collaborative design, so it is difficult to comprehensively consider the important indica...
