Add fixed, free, or floating vertical tangents to build constraint-based profile geometry.
To access the vertical tangent creation commands, click the arrow next to the tangent creation command displayed on the toolbar. The 
Draw Fixed Tangent By Two Points command is displayed by default.
After clicking a button on the Profile Layout Tools toolbar, follow the command prompts on the command line.
You can use transparent commands to specify a station and elevation when you are prompted to select a point. For more information, see Transparent Commands.
