About

Master the art of creating custom subassemblies with Autodesk Subassembly Composer (SAC) in this comprehensive 8-week advanced course. Learn to build intelligent, parametric subassemblies that solve unique design challenges and dramatically improve your workflow efficiency.

This course takes you from basic concepts to advanced techniques, teaching you how to create subassemblies with complex logic, conditional design rules, and intelligent targeting capabilities. You’ll learn the same techniques used by top Civil 3D consultants worldwide.

Through hands-on projects, you’ll build custom subassemblies for roadways, drainage systems, retaining walls, and specialized infrastructure. You’ll understand how to use flowcharts, parameters, and targets to create truly dynamic designs that adapt to changing conditions.

By the end of this course, you’ll have a library of custom subassemblies and the skills to create any subassembly your projects require. This is the ultimate course for Civil 3D users who want to unlock the full power of corridor modeling.
