The last segment must be defined with the Close perimeter command, otherwise, the chute is not completed. The end point definition window is similar to that used for the origin point except that the chute end point to be specified is by definition the point of contact of the foundation in the downstream direction. The coordinate for a given X or Y is calculated by CADAM3D using the foundation profile. Once this step is completed, the entire section is shown in the chute window.

A depth or thickness may be entered into the appropriate field to complete the chute definition. The total volume of concrete is calculated using the command Compute volume.
