A visual subassembly designer for AutoCAD Civil3D

Section 3D is an add-on application which allows you to create and edit the dynamic corridor in AutoCAD Civil 3D without having to create the custom subassemblies.

Ease and flexibility.

With Section 3D you can easily create and edit complex corridor models through a graphic interface with unparallel power and flexibility without any programming.

Section 3D is not any different from those from the supplied subassemblies.

But with Section 3D you are completely free from the constraints and limitations built into the subassembly input parameters and program logic.
