About the Behavior of Alignment and Profile Entity Types when Exchanging Data Between AutoCAD Civil 3D and Autodesk InfraWorks 360

Certain AutoCAD Civil 3D alignment and profile entity types produce design roads that can be edited in Autodesk InfraWorks 360, other types produce design roads that are not editable, and certain AutoCAD Civil 3D profile entities cannot be brought into InfraWorks 360.

Alignment and Profile Entity Types that Produce Design Roads that Can Be Edited in InfraWorks 360

When you open AutoCAD Civil 3D drawings that contain alignments and profiles in InfraWorks 360, the design roads that are created in InfraWorks 360 may be read-only. If a design road that you bring into InfraWorks 360 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 360.

The following AutoCAD Civil 3D alignment entity/constraint types create design roads that are editable in InfraWorks 360. All other types create design roads that are not editable in InfraWorks 360.

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 360.

The following AutoCAD Civil 3D profile entity/constraint types create design roads that are editable in InfraWorks 360. All other supported types create design roads that are not editable in InfraWorks 360.

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 360.

Profile Entity Types that Are Not Brought Into InfraWorks 360

The following AutoCAD Civil 3D profile entity/constraint types are not brought into InfraWorks 360.

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
