Description

Technical Field

[0001] The invention relates to the field of engineering design, in particular to a method and equipment for quickly establishing a CIVIL3D route and longitudinal section model. Background Art

[0002] CIVIL3D is a modeling software for civil infrastructure design and construction. It is widely used in engineering fields such as bridge engineering, tunnel and underground engineering, rail engineering, intercity high-speed railway and intercity rail transit. In CIVIL3D, routes and designed longitudinal sections are the most basic control lines for strip buildings such as roads, bridges and tunnels, and are extremely important links in modeling. At present, CIVIL3D has its own method for creating routes. The first is to create routes from objects, select straight lines, curves or polylines to create. This method replaces the transition curve with a polyline, which cannot meet the accuracy requirements of small radius transition curves, especially road interchange ramps, so this method can only be used for roads without transition curves; the second method is to use the route layout tool to create, which is completely completed by manually entering data or specifying relevant control points on the map, which is extremely inefficient and prone to errors.

[0003] In summary, it is now necessary to develop a method that is both fast and meets the accuracy requirements to establish routes, design profiles, terrain surfaces, terrain profiles and profile views. Summary of the invention

[0086] Furthermore, the data in the table file is read through VBA.

[0087] Example 2

[0088] like Figure 2 As shown, this embodiment is a specific implementation of the method for quickly establishing a CIVIL3D route and longitudinal section model described in Example 1, comprising the following steps:

[0089] (1) Data preparation: Input route parameters, design longitudinal section parameters, and terrain coordinate point data in a fixed format in the EXCEL file. If the route has broken link parameters, input them accordingly. The worksheet names corresponding to each type of data are: route parameters, longitudinal section parameters, terrain point data, and broken link parameters.

[0090] The format of the route parameter when it is the intersection method (see Appendix Figure 3 ) is: "Point name, mileage, north coordinate, east coordinate, length of front transition curve, length of rear transition curve, radius of circular curve" (where commas indicate data separation, the same below). For the starting and ending points, only the point name, mileage and coordinate values ​​are entered, and for other intersection points, all data are entered. The starting and ending points of the route must be on a straight line segment.

[0091] The format of the route parameter when it is the line element method (see Appendix Figure 4 ) is: "starting point mileage, north coordinate, east coordinate, tangent azimuth, starting point radius, end point radius, line element length", where a positive starting and end point radius is a right-turn curve and a negative starting and end point radius is a left-turn curve. If both are 0, it is a straight line.

[0092] Design longitudinal section parameter format (see attached Figure 5 ) are: "slope change point mileage, slope change point elevation, vertical curve radius". The chain break parameters are: "original chain break before pile number, chain break before pile number, chain break after pile number". Terrain coordinate point data format (see attached Figure 6 ) is: "Serial number, north coordinate, east coordinate, elevation".

[0093] (2) Open the CIVIL3D VBA Manager, add EXCEL references and CIVIL3DCOMAPI references in the VBA project, and instantiate the EXCEL project, EXCEL workbook, and EXCEL worksheet in the VBA program to link to the table generated in step (1) to facilitate subsequent data reading.

[0094] (3) Instantiate an AeccDocument project object in the VBA program and link it to CIVIL3D.

[0095] (4) Create a new AeccAlignment blank route object.

[0096] (5) The VBA program reads the data in the EXCEL "Route Parameters" worksheet and determines whether the data is the intersection method or the line element method based on the data format: if the content of cell A1 is "point number", it is the intersection method; if the content of cell A1 is "starting point mileage", it is the line element method.

[0097] (6) Step (5) is determined to be the intersection rule. The tangent azimuth, steering information and coordinates of the five major stakes of all intersections are calculated. After the calculation is completed, the straight line of the route starting point segment is drawn:

[0098] 'Define a CIVIL3D route line object and use the alignment.Entities.AddFixedLine1(p1,p2) method to draw the route line.' p1 and p2 are the coordinates of the route starting point and the first intersection point respectively.

[0099] (7) Process the intersection data in order: If there is no transition curve at this intersection (the lengths of the front and rear transition curves are both 0), use the oalignment.Entities.AddFixedCurve6 (starting point coordinates, end point coordinates, curve radius, curve turn) method to draw a circular curve; if there is a transition curve at this intersection (either the length of the front and rear transition curves is not 0), use the oalignment.Entities.AddFreeSCSGroup1 (front straight line ID, rear straight line ID, front transition curve length, circular curve radius, rear transition curve length, curve turn, transition curve type) method to draw the transition curve and circular curve. After drawing the curve, use the oalignment.Entities.AddFixedLine1 method to draw the straight line segment to the next intersection.

[0100] (8) Repeat step (7) until all intersection data are processed.

[0101] (9) Step (5) is determined as a line element rule. The line type of the line element is determined based on the line element start and end point radius data: if it is a straight line (the start and end point radii are both 0), the oalignment.Entities.AddFixedLine1 method is used to draw the straight line; if it is a circular curve (the start and end point radii are equal and not equal to 0), the oalignment.Entities.AddFixedCurve6 method is used to draw the circular curve; if it is a transition curve (the start and end point radii are not equal), the oalignment.Entities.AddFixedSpiral2 (connected to the ID of the previous element, curve start point coordinates, curve tangent point coordinates, curve start point radius, curve end point radius, curve length, curve direction, curve type) method is used to draw the transition curve.

[0102] (10) Repeat step (9) until all line element parameters are processed.

[0103] (11) Use the alignment.ReferencePointStation method to set the starting mileage of the route.

[0104] (12) Read the data of the EXCEL "Broken Chain Parameters" worksheet. If the data is empty, no processing is required. If the data is not empty, use the alignment.StationEquations.Add(original chain breaking pile number, chain breaking pile number, chain breaking pile number) method to process all broken chain parameters.

[0105] (13) Create a new AeccProfile longitudinal section object.

[0106] (14) Read the data from the EXCEL “Design Longitudinal Section” worksheet.

[0107] (15) Process the slope change point data of the designed longitudinal section: Use the oAeccProfile.Entities.AddFixedTangent(starting point coordinates, end point coordinates) method to draw the straight longitudinal slope segment of the designed longitudinal section, and use the oAeccProfile.Entities.AddFreeSymmetricParabolaByLength(previous straight line segment ID, subsequent straight line segment ID, longitudinal section curve type, curve length, True) method to draw the curved longitudinal slope segment of the designed longitudinal section, where the curve length is the horizontal projection length.

[0108] (16) Repeat step (15) until all the designed longitudinal section intersection data are processed.

[0109] (17) Create a new AeccTinSurface TIN surface object and set the surface name, surface description, surface layer, surface background and surface style.

[0110] (18) Read the data from the "Topographic Point Data" worksheet in the EXCEL file and input it into a Variant array. Then use the oTinSurface.AddPointMultiple Variant method to add the Variant array to oTinSurface to generate a TIN terrain surface.

[0111] (19) Create a route terrain profile: use Profiles.AddFromSurface(terrain profile name, type, style, surface name, start mileage, end mileage, layer name) method.

[0112] (20) Create a profile view: Create a new AeccProfileView profile view object and use the ProfileViews.Add method to create a profile view:

[0113] Dim oProfileViewAsAeccProfileView

[0114] Set oProfileView = oalignment.ProfileViews.Add (profile name, layer name, insertion point coordinates, profile style, profile label style)

[0115] At this point, the route, design profile, terrain surface, terrain profile and profile diagram have been established, and the output is the route plan, terrain surface and corresponding profile model. The generated graphics are attached. Figure 7 and attached Figure 8 shown.
