About the Behavior of Alignment and Profile Entity Types when Exchanging Data Between AutoCAD Civil 3D and InfraWorks

Certain AutoCAD Civil 3D alignment and profile entity types produce design roads that can be edited in InfraWorks, other types produce design roads that are not editable, and certain AutoCAD Civil 3D profile entities cannot be brought into InfraWorks.

Alignment and Profile Entity Types that Produce Design Roads that Can Be Edited in InfraWorks

When you open AutoCAD Civil 3D drawings that contain alignments and profiles in InfraWorks, the design roads that are created in InfraWorks may be read-only. If a design road that you bring into InfraWorks is not editable, "Editing Disabled" will be displayed on the asset card for that design road.

An AutoCAD Civil 3D alignment and its associated profile must be exclusively comprised of editable entities in order for the design road to be editable in InfraWorks.

The following AutoCAD Civil 3D alignment entity/constraint types create design roads that are editable in InfraWorks. All other types create design roads that are not editable in InfraWorks.

Alignment Entity Type	Command Used to Create Entity	Constraint Type
Line	Fixed Line (Two Points)	Point 1, Point 2
Circular Arc	Free Curve Fillet (Between Two Entities, Radius)	Radius
Spiral-Curve-Spiral	Free Spiral-Curve-Spiral	Spiral 1 Length, Spiral 2 Length, Radius

Note: The entities that are created when you use the Create Best Fit Alignment command are also editable in InfraWorks.

The following AutoCAD Civil 3D profile entity/constraint types create design roads that are editable in InfraWorks. All other supported types create design roads that are not editable in InfraWorks.

Profile Entity Type	Command Used to Create Entity	Constraint Type
Line	Fixed Tangent (Two Points)	Point 1, Point 2
Parabola	Free Vertical Curve (Parabola)	Curve Length
Parabola	Free Vertical Curve (Parabola)	K Value

Note: The entities that are created when you use the Create Best Fit Profile command are also editable in InfraWorks.

Profile Entity Types that Are Not Brought Into InfraWorks

The following AutoCAD Civil 3D profile entity/constraint types are not brought into InfraWorks.

Profile Entity Type	Command Used to Create Entity	Constraint Type
Line	Fixed Tangent - Best Fit	Best Fit Fixed
Line	Float Tangent - Best Fit	Best Fit Float
Parabola	Fixed Vertical Curve - Best Fit	Best Fit Fixed
Parabola	Floating Vertical Curve - Best Fit	Best Fit Float
Parabola	Free Vertical Curve - Best Fit	Best Fit Free
