In the Triangulate Surface dialogue there is a new “Create as Profile Model” option. The “Create as Profile Model” option appears when you have an element selected when you Triangulate Elements.
The “create as a profile model” option allows you to create a surface from a single vector element. This allows you then to use the profile tools to visualize that single vector. In other words, it saves you having to copy offset that single element just to create the surface to visualize that element.
