In this video, you’ll see an in-depth example of how a civil engineer can use the 3DEXPERIENCE platform to design a railway/bridge structure.
The process begins by either leveraging the included Civil Engineering Catalogues (i.e. smart tools, reusable components, and IFC-compliant objects which speed up the creation of the skeleton), or the design can start from scratch.In our railway/bridge project example, the user creates a site from scratch, inserts the terrain, and imports a point cloud to set up the canvas for the structure. The railway’s center curve, imported from a IGES, STEP, or IFC format, is geo-located onto the map.
The Terrain Preparation app allows the user to create a mesh on the point cloud, and apply a contour map to reveal the elevation curves.
You’ll also see how to geo-locate objects by using coordinates from Google Maps, in order to insert 3D mockups of local landmarks, analyze the project’s environmental impact, run noise simulations, and more.
A Large Range Scale is available to mix large range objects with normal range objects within the same view.Civil Design automatically generates excavation along the center curve, driven a by parametric trapezoidal profile, and estimates the volume removed from the terrain mesh.
The user can modify the side angles and base width as needed. This allows the engineer to compute the excavated volume and get an early estimate of cost and duration.
The project in our demonstration incorporates a constant deck and a cantilever. You’ll see how the engineer creates each using a combination of templated objects and custom modifications.
To make multiple design options, the engineer quickly creates alternatives by selecting the piers and applying a different template.
The edited elements are color-coded to highlight the difference between versions.The Span Cutter tool automatically creates arch segments and splitting surfaces between each segment.
Manufacturing simulations help the engineer determine how the segments will be optimally constructed off-site or on-site.
