ASE Civil passively generates a 3-dimensional, mathematically-accurate (parabolic vertical curves) 'TOP' or 'DATUM' surface model for each alignment within the vertical design drawing after paving design data is shared. All paving feature details are included in the model output, which is refreshed each time paving feature data is updated. Site defaults are applied to local and divided roads initially, however controls allow adjustments to assembly configurations on a 'site-wide' basis, 'alignment-specific' or 'component-specific' scope.
The following design elements are needed to generate ASE corridor models:
Base Map Control
Corridor models are not created explicitly. They are a bi-product that results when an alignment's paving design data has been shared to the ASE project data folder. When Base Map Control data is available and paving features are defined, ASE joins those two design components to create a physical representation of the managed design in 3-D space.
Define alignments (centerline only)
Define Base Map Control
Develop Profile or Surface data
Set Design Markers
Define paving features
Share paving data
Result = ASE corridor model
ASE's corridor models are created without the need for offset alignments or offset profile designs. Only the centerline is referenced, while Base Map Control algorithms perform the spatial calculations, driven by the vertical design data.
Preferences (Site Defaults)
Establish default values for all alignments to use upon initial creation. Local road configurations are specified separately from divided road types. Section thickness and surface output type can also be specified, along with other settings that affect performance.
Deviate from the site default configurations by setting a specific alignment current and adjusting the preferences for that corridor only or for one of its components.
When current settings suppress automatic updating of corridors, use this option to completely regenerate the horizontal and vertical control data and 3-D output for a single alignment, a selected group or the whole site.
Civil 3D Surfaces
ASE's corridor models were developed specifically for the purpose of using in Civil 3D surfaces to assist in contouring, visualization and volume calculations.
