Description

A method based on REVIT for automatic transmission of parameters and wells in general drawing of power engineering

technical field

The invention belongs to the field of three-dimensional digitization, relates to the field of digital three-dimensional design model modeling, and is applied to the automatic transmission of parameters and placement of wells for three-dimensional design models of electric power engineering.

Background technique

3D digital modeling of BIM, the BIM process uses centralized digital 3D modeling as the core resource. The BIM model is a model formed by multi-person participation, integration of resources from various disciplines, and teamwork. Each building participant plans the data model while also allowing others' permissions and data modification. The BIM model consists of detailed BIM units, such as doors, walls, equipment, etc. BIM modeling will greatly improve work efficiency, which means that it can prevent potential conflicts that may occur during the planning phase of a construction project. BIM systems allow architects and designers to more quickly and easily understand and implement gated, automated and other product features.

At present, there are seven series of BIM 3D modeling software: Revit series software, Bentley series software, ArchiCAD series software from Tusoft, Tekla series software from Trimble, CATIA series software from Dassault, MagiCAD series software from Glodon and Rhino series software software. Among them, the Revit series software is aimed at specific professional architectural design and documentation systems, supporting design and construction drawings at all stages. 3D software is a Building Information Modeling (BIM) solution for civil engineering design and documentation. AutoCAD Civil 3D helps civil engineering professionals working on transportation, land development, and water projects stay aligned, explore design options more easily and efficiently, analyze project performance, and deliver consistent, higher-quality documentation—everything All in the familiar AutoCAD environment.

However, as a general-purpose software, Revit cannot meet specific specialties. On this basis, Revit, as a BIM modeling platform software, provides basic functions for users to do BIM modeling. The general modeling platform provides API (Application Programming Interface) for third parties to do Revit secondary development. The result is a Revit plug-in that creates models and reads BIM model information. It can realize batch operation and intelligent operation, and can also open up the secondary development of Revit with other software, so that some simple and repetitive work can be done by the computer for us, thus greatly reducing the workload of engineers.

The prior art has the following defects:

1. In Revit 3D modeling, the host of various components such as wells, walls or cable trenches must be floors. When 3D modeling, you need to use floor properties to create a new site. Whether it is based on the outline of the site or the CAD sketch, when the site is built, the internal details of the site are complex, and the site is not flat. Check and modify.

2. After the first step of drawing the site, manual confirmation of the details inside the site, especially the sloped areas, is prone to errors and low efficiency.

3. When all kinds of wells need to be placed in order to arrange underground pipelines, it is often necessary to manually calculate the bottom elevation of the well according to the diameter of the well cavity, the site elevation, and the pipeline penetrating the well. In particular, the complex slope of the site and the pipeline brings difficulties to the calculation of the bottom elevation, and the calculation accuracy cannot be guaranteed. Often, by increasing the burial depth, the construction cost is greatly increased, and even the problem of collision is caused.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a REVIT-based automatic transmission of power engineering general drawing, which is often required to manually calculate the bottom elevation according to the surrounding environment when placing various wells in the power engineering pipeline network, which has the characteristics of low efficiency, large amount of calculation, and high error. For the method of participating wells, a set of plug-ins for automatically placing various wells has been independently developed according to RevitAPI, and the bottom elevation is automatically calculated according to the surrounding environment. It only takes two or three steps to operate the mouse click, and the site can be generated in less than one minute. And divide the layout of the site and the well, the plug-in is easy to install, has high calculation accuracy and good interaction, which greatly improves the work efficiency, improves the accuracy, and saves the cost.

In order to achieve the above-mentioned purpose, the technical scheme of the present invention is: a method for automatic transmission of reference and layout of wells based on REVIT-based general drawing of electric power engineering, comprising the following steps:

(1) Import the CAD 2D site and road model into Revit or generate the site based on the elevation point data of CIVIL3D;

(2) Create a site: Pick the closed outer contour of the site to generate a site, and the property of the site is floor at this time;

(3) Divide the site: Pick up the internal components of the site including roads and walls, project them into the site generated in step (2), and divide the site to obtain the real site boundary information;

(4) According to the slope and elevation information, generate a site with slope;

(5) Establish a three-dimensional pipeline model;

(6) Establish related well families, set the parameters related to the generation of bottom hole elevations as instance parameters, and load them into the project;

(7) Place well: Select the well to be placed in the well window, drag it to the project, and generate an instance at the position where the well needs to be placed. Multiple wells can be generated by continuous operation, and the placement can be ended by pressing the ESC key;

(8) Set the well height: In the 3D view, adjust to the upper view, and turn the pipelines around each well in turn. One-click can generate the bottom elevation, and complete the cutting of the pipelines penetrating into the well.

In an embodiment of the present invention, steps (1) and (2) are specifically implemented as: importing the 2D boundary information of CAD or the 2D boundary model of the site from CIVIL3D into Revit, and clicking Create Site to pick the closed outer contour to generate the base site , and set the property of the generated site as floor; the floor in Revit can be set with elevation, slope, start, and map, which meets the requirements of the site.

In an embodiment of the present invention, the parameters related to the bottom hole elevation in step (6) include: well burial depth, roof thickness, well circle height, and height from the ground.

In an embodiment of the present invention, in step (8), the well height, that is, the calculation formula of the bottom hole elevation is as follows:

Bottom hole elevation = top plate elevation - (well buried depth - top plate thickness - well circle height + height from the ground) = minimum pipeline elevation - bottom plate thickness.

Compared with the prior art, the present invention has the following beneficial effects: the present invention independently researches and develops a set of plug-ins for automatically placing various wells according to revitAPI, and automatically calculates the bottom elevation according to the surrounding environment. It takes less than a minute to generate the site and divide the site and well layout. The plug-in is easy to install, has high calculation accuracy, and has good interactivity, which greatly improves work efficiency, improves accuracy, and saves costs.

The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

The present invention is a method for automatic transmission of reference and layout of wells based on REVIT-based general drawing of electric power engineering. The main points include: (1) Import the CAD 2D site and road model into Revit or generate the site based on the elevation point data of CIVIL3D; (2) Create the site: Pick the closed outer contour of the site to generate the site, and the property of the site is the floor at this time. ; (3) Divide the site: Pick up the internal components of the site such as roads and walls, project them into the site in (2), and divide the site to obtain the real site boundary information; (4) According to the slope and elevation information, generate a site with a slope; (5) Establish a three-dimensional pipeline model; (6) Establish a related well family, and set the parameters related to the generation of bottom hole elevation as instance parameters and load it into the project. (7) Place well: Select the well to be placed in the well window, drag it to the project, and generate an instance at the position where the well needs to be placed. Multiple wells can be generated by continuous operation, and then press the ESC key to end the placement. (8) Set the well height: In the 3D view, adjust to the upper view, and turn the pipelines around each well in turn. One-click can generate the bottom elevation, and complete the cutting of the pipelines penetrating into the well.

The following are specific implementation examples of the present invention.

Figure 1 shows the basic flow of this method. First, import the CAD 2D boundary information and the CIVIL3D 2D boundary model of the site into Revit, click Create Site to pick up the closed outer contour line to generate the base site; then click the Divide Site button to select the outer wall, Boundaries such as roads are automatically projected onto the base site to complete site segmentation; then the segmented site is input with elevation and slope direction to construct a real site. Then build the entire pipeline. Create a family file of related wells, and set the parameters that affect the bottom hole elevation as instance parameters, and load them into the project after completion. Click to arrange wells, drag the related wells to the model, and click the left mouse button to place the wells at the corresponding positions. Finally, click to set the well height, select the surrounding pipelines for the wells in the previous step in turn, and the system automatically calculates the bottom hole elevation and cuts the pipelines to complete the well layout.

Flow Description:

Step 1. Generate the outer boundary of the origin.

The outer boundary of the site is the approximate range of the model site, and the accuracy of its inner boundary is relatively low. It can be drawn by importing CAD's 2D boundary or CIVIL3D elevation information. Since the host of components such as wells and cable trenches is a floor, the properties of the generated site should be set to floor. Floor slabs in Revit can be set to elevation, slope, start, texture, etc., to meet the requirements of the site.

Step 2. Divide the site

As shown in Figure 2, the inner boundary of the site is complex, and the manual line drawing is more complicated, which cannot be accurately drawn and is prone to errors. Through the function of dividing the origin of the present invention, fool-like drawing can be realized. Pick up the inner boundary outlines of walls, roads, etc., and the system will automatically project these inner boundary lines to the top surface of the floor, find a closed loop, complete the site segmentation, and greatly improve the drawing efficiency and accuracy.

Step 3. Enter the slope and elevation information to complete the site construction.

Since the site itself is not flat, the site with a large number of Elevation II projects is mostly flat except for the landscape. In order to better fit the floor to the site, it is necessary to level the site and input the elevation and elevation information to obtain the elevation information of the top surface of the floor that affects the elevation of the well bottom.

Step 4: Build the pipeline.

As shown in Figure 3, the pipeline is the surrounding environment of the well, and the bottom elevation of the well is closely related to the lowest bottom elevation of the pipeline where the well intersects. The system will automatically calculate and draw and display it in the 3D model.

Step 5. Create a well family

As shown in Figures 4 and 5, a family of wells is established in the family module, and the reference elevation is associated with the top surface of the plate. And edit the properties of the family, among which the properties related to the calculation formula of the bottom elevation of the well, such as: well depth, roof thickness, well circle height, height from the ground and other properties are set as instance parameters.

Step 6. Place the well

As shown in Figure 6, click to arrange wells, click to select the corresponding wells, drag them to the project, and click the left button at the appropriate position to generate multiple wells. Press the ESC key to end the operation. The bottom hole elevation is the default value.

Step 7. Set the well height

The calculation formula of bottom hole elevation is as follows:

Bottom hole elevation = top plate elevation - (well buried depth - top plate thickness - well circle height + height from the ground) = minimum pipeline elevation - bottom plate thickness

According to the prompts in the status bar, select the well and the penetrating pipeline around the well in turn, the system will automatically change the parameters of the bottom hole elevation, and at the same time, the cut-off pipeline will be extended into the part of the well, and finally the layout of the well will be completed.

Typical application examples of the present invention are shown in Figures 7-10, in which Figure 7 is an example of a well placement diagram of the present invention, Figure 8 is an example of a pipe penetration well diagram of the present invention, and Figure 9 is an example of a pipeline diagram around a selected well according to the present invention. 10 is an example of the automatic generation of bottom hole elevation and cutting pipeline diagram of the present invention.

The above are the preferred embodiments of the present invention, all changes made according to the technical solutions of the present invention, when the resulting functional effects do not exceed the scope of the technical solutions of the present invention, belong to the protection scope of the present invention.
