What's New

This section describes recent changes in Civil Engineering 3D Design.

This page discusses:

R2022x FD01 (FP.2205)

Creating Transitions on Vertical Alignments

You can create transitions on vertical alignments for road and railway tracks using a parabolic curve or an arc.
Benefits: You can now create transitions on both horizontal and vertical alignments.
For more information, see Creating a Transition

Extracting Large Point Cloud into a Polyhedral Mesh

In the Extract Polyhedral Large Cloud of Points dialog box, a new option is added to the polyhedral extract feature to remove outlier points (computed by the 3D mesher). You can use a slider to choose the percentage of the removed outliers.

A progress bar is added to the extract panel. It is also visible in the extract panel of the Terrain Preparation app.

Benefits: You can ignore only a portion of outlier points.
For more information, see Extracting and Converting a Portion of a Large Point Cloud into a Polyhedral Mesh

City Connection

In the Civil Engineering 3D Design app, you can import a predefined city site created in the city apps.
Benefits: You can retrieve city objects such as Referentials, Sites, Polygons, and Geoitems etc. in the civil context, see their properties and edit them.
For more information, see Importing City Objects

Compound Oval Curve

In the Civil Engineering 3D Design app, the Compound Oval Turn contextual command is now available.
Benefits: This new command allows the creation of Compound Oval Curves.
For more information, see Creating a Horizontal Curve

Simple Curve Dual Composition

Three new contextual commands, Switch curve PI composition, Simple Curve Dual PI, and Simple curve dual PI tangency are now available.
Benefits: These new commands allow the creation of U-Turn curves.
For more information, see Creating a Horizontal Curve

Linear and Curvilinear Pattern Enhancements

The pattern designer can visualize the pattern group distances between the axes and information about the translational or offset distances of the group axis. New axis displacement capabilities are available to design a compatible and precise pattern.


You can edit the group length and the internal axis with the help of the Robot.

Benefits: A new visualization and positioning of the pattern axis systems are available to comply with the terrain or type of bridge.
For more information, see Creating a Linear Pattern Creating a Curvilinear Pattern

Interruption of the Sketcher geometry solver

A new preference is available for alignments in the Civil Engineering 3D Design app. You can constrain the Sketcher geometry solver to converge to a solution within a customizable time limit.
Benefits: The Sketcher geometry solver could take up to 10 minutes to converge, in which case it would usually end up displaying an inconsistent result. You can now define a maximum time above which your sketch is determined inconsistent, which allows you to work more efficiently on vertical and horizontal alignments.
For more information, see Alignment

Customizing the Display of Point

You can now customize the description and the visualization of a point through an xml file and a dedicated preferences panel.
Benefits: Customizing the display of points facilitates and improves the design process.
For more information, see About Visualization About Points

Sinusoidal and Cosinusoidal Transition Types

You can now create a sinusoidal or cosinusoidal transition between two curves in compound and reverse configurations. The transition can be created at the start or end of the curve.
Benefits: You have more flexibility in the creation of your design.
For more information, see Creating a Horizontal Curve

Excavation and Filling

The excavation and filling options are now available in a dedicated panel by clicking Excavation and Filling from the Alignment section of the action bar. A new attribute to define a vertical offset for tunnel computation is also available.
Benefits: You can access excavation and filling options faster.
For more information, see Computing Excavation and Filling Volumes

Alignment Panel Enhancements

The following enhancements have been made:
  • You can now use a bounding box associated with the horizontal alignment to split the 3D item you want to transfer in the vertical sketch.
  • You can select the visualization mode of your choice for each 3D item you want to transfer.
  • The terrain multiselector is now a single selector and a new geology multiselector is now available.
Benefits: You can generate lighter polyhedral imports with the bounding box and the management of items to transfer has been improved.

R2022x GA

Alignment Camera Traveling

You can click Play from the Road or Railway section to animate the camera traveling along a 3D curve super-imposed on an existing landscape. The Play options let you customize the display of different parameters.
Benefits: Experimenting your road or railway design throughout an ecosystem facilitates the identification of visibility issues.
For more information, see Experiencing Simulations on 3D Alignments

Visualization and Edition of the Geolocated Coordinates of Geometric Elements

When the Display Geolocated Position command in the View section of the action bar is selected, the Easting and Northing geolocated coordinates replace the display of the H and V values in the tools palette toolbar or editing panels to define the position of a geometry.
Benefits: You can manage the display and edit of the geolocation coordinates when editing a geometry.
For more information, see Displaying the Geolocated Position

Discipline Definition Available on Cross Sections

While creating a subgrade type, you can edit the Feature Instantiation Method of object types (OT) with a given discipline (road, railway, platform, or undefined). The content provided in the SubgradeTypicalCrossSections.3dxml is also updated to take benefit of it.
Benefits: When using a command requesting an object type of subgrade type, only the relevant object types are displayed.
For more information, see Creating a Platform Earthwork Creating or Splitting the Subgrade Layer of an Infrastructure Creating or Splitting a Road/Railway Earthwork

AEC PLM Dictionary Update

The support of IFC attributes has expanded. Industry Class Foundation (IFC) is an object-oriented file format used by the AEC industry (architecture, engineering, and construction) to exchange and share information between a set of software.
You can now use more IFC standard entities, Pset, and Qto for Electrical and Equipment domains.
Benefits: Using IFC types lets you structure content and design a civil engineering infrastructure with the building and civil engineering dedicated types. You can search for Object Types with their IFC type criterion more quickly.
