Hi there, I'm very new in Civil 3D.I wanted to create a custom subassembly of curb.But i'm finding difficulty in creating it, since it's a complex one.There are mainly two types of curb, and under each type there are another 3 types (which is different in profile).Among these 3 subcategories, one profile is a blend type profile. The height of the profile varies along with the length of profile. How is it possible to create such a profile in SAC?Also i have very less idea to create the flowchart creation.Whenever i tries to create the flowchart it always fails.Please have a look in the above image. Thanks in Advance
