One of my favorite modifier tools out of 3ds Max is the sweep modifier. I think many people overlook this modifier or just do not know what it does.
The Sweep Modifier basically extrudes a cross-section along an underlying spline or NURBS curve path. Similar to the Loft compound object but way more efficient and easier to modify for revisions and changes.
It also comes with built-in 12 common cross-sections like angles,channels, tubs, pipe, egg, and beam shapes. Each of the built-in cross-sections has a parameter roll out that you can adjust offering more variations. You can also create your own cross section which is great for crown moldings.
This handy modifier speeds up my workflow and makes changing later a breeze. I often put sweep place holders for trims and moldings using the built-in sections and come back later and try out different custom profiles and see how it looks through out the whole space with one click. The ability to specify the angle of your profile and how it positioned on the spline is great for experimenting.
Common Uses where I use sweep:
Molding and Trim pieces: Frames for doors, windows, pictures, graphics. Trims around walls like wall bases, top crown molding, exterior trims, roofs, gutters.
Decorative line work: Scroll work for railings, windows, doors,
Spline Objects that change: Hoes, bag handles.
I highly suggest you try out this modifier and see how many different uses you can find for sweep.
