Embodiment 1

[0037] Provides a method for rapid modeling of network roads in Civil3D by using height-controlled surface construction, as shown in the attached figure 2 As shown, the steps are as follows:

[0038] Step 1. Generate a height-controlling surface, specifically: build a height-controlling surface (surface) in Civil3D by controlling height (expressed by the object of aeccpoint), and place it in an empty site.

[0039] Step 2. Generate the alignment set of networked roads, specifically: convert the alignments expressed using polyline2d into uniformly named Civil3D alignment objects (alignment), and obtain the alignment set of networked roads . In this step, the method described in 201810882559.X to automatically name networked roads according to sorting rules in civil3d can be used to generate a set of alignments, or the polylines can be individually aligned for each road.

[0040] Step 3. Generating feature lines, specifically: converting the alignment set of networked roads i...

Embodiment 2

[0052] The present invention also provides a device for quickly modeling networked roads in Civil3D using height-controlled construction surfaces, including:

[0053] The height-controlling surface generation module is used to construct a height-controlling surface (surface) in Civil3D by controlling height (expressed by the object of aeccpoint), and place it in an empty site (site).

[0054] The alignment set generation module of the networked road is used to batch convert the alignment expressed by polyline2d into a uniformly named Civil3D alignment object (alignment), and obtain the alignment set of the networked road. Among them, the method described in 201810882559.X to automatically name the meshed roads according to the sorting rules in civil3d can be used to generate the alignment set, or the polylines can be individually aligned for each road.

[0055] The feature line generation module is used to convert the alignment set of networked roads into a feature line (featu...

Abstract

The invention provides a method and a device for quickly modeling a mesh road by utilizing a height control construction curved surface in Civil3D, and the method the following steps: generating the height control curved surface, generating an alignment set of the mesh road, generating element lines, generating element line key points, obtaining element line key point elevations, generating longitudinal sections of the mesh road, creating an assembly, generating an intersection model in the road network, and generating a road object. According to the method, the mesh road can be quickly and accurately designed and modeled.

Description

technical field [0001] The invention belongs to the fields of road design, road planning, and BIM, and in particular relates to a method and a device for quickly modeling networked roads in Civil3D by using height-controlling construction surfaces. Background technique [0002] Network roads are the most common road configuration in area-level or city-level development. When planning and designing network roads, it is necessary to first determine the plane alignment and rough cross-sectional layout of all single roads in the network road, and then determine Controlling elevation at the intersection of network roads (referred to as controlling height), as attached figure 1 As shown, the commonly used design modeling method is to carry out the planning and design conditions of a single road according to the planning and design conditions such as the plane (alignment), cross-section (layout) and height control (or longitudinal design) determined in the network road planning of ...
