Problems solved by technology

Now the use of SWMM software mainly saves the CAD drawing directly as a .wmf file, imports it into SWMM as the background, and manually enters the relevant attribute data according to the background picture pipeline, sub-catchment and other objects, and the operation is cumbersome

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] A kind of method of CAD of the present invention turns the inp file of SWMM, comprises the following steps:

[0019] Step 1: Convert the CAD drawing into PDF format, and then use the software to convert the PDF into JPG format and save it as the background image, such as figure 1 shown.

[0020] Step 2: Create a new layer in CAD, select several anchor points in the figure, generally you can choose 5 to 8; mark these anchor points with multiple line segments, close all other layers, and copy this layer All the elements in the file are transferred to the newly created CAD file, and the newly created CAD file is saved in DXF format.

[0021] Step 3: Open EPANET, create a new blank file, and export it in the form of pipe network. The output file is in .inp format. Use the software to save the file in DXF format saved in step 2 to this .inp file exported in the fo...

Abstract

The invention discloses a method for converting CAD to SWMM inp files: converting the CAD drawing into PDF format, then converting the PDF into JPG format, and keeping it as a background image; creating a new layer in CAD, and selecting an anchor point in the drawing , mark the anchor points with line segments, close all other layers, copy all elements in this layer to the newly created CAD file, and save the newly created CAD file in DXF format; open EPANET, create a new blank file, and use the pipe network format export, the output file is in .inp format, save the saved DXF format file into this .inp file; use SWMM to open the .inp file after importing information, after opening, you can see the anchor point on the desktop, call and save as For the background image in JPG format, adjust the size of the image to make the position of the anchor point consistent with the background image, and draw the object according to the background image. The present invention acquires data automatically, does not need manual input, and saves time.

Description

technical field [0001] The invention relates to a method, more specifically, relates to a method for converting CAD to SWMM inp files. Background technique [0002] SWMM is a dynamic precipitation-runoff model, which is mainly used to simulate a single precipitation event or long-term water quantity and water quality simulation in a city. Its runoff module part comprehensively handles the precipitation, runoff and pollution loads that occur in each sub-basin. The model can track and simulate the water quality and quantity of runoff produced by each sub-basin at any time at different time steps, as well as the flow, water depth and water quality of water in each pipe and channel. It is widely used in the planning, analysis and design of storm floods, combined sewers, sewers and other drainage systems in urban areas worldwide, and in other non-urban areas. Now using SWMM software is mainly to directly save the CAD drawing as a .wmf file, import it into SWMM as the background...
