PLS-CADD/SURVEY : Surveyor's edition of PLS-CADD that provides terrain modeling and drafting capabilities, but not structure spotting, loads, clearances, or sag-tension ( compare editions ). It develops a Sag-Tension report as well as Stringing Charts for a user definable range of span lengths and stringing temperatures. PLS-CADD/ULTRALITE: Streamlined version of PLS-CADD for quick modeling of a single span of conductor or wire.

(PLS-CADD/LITE does not open or act as a viewer for PLS-CADD Standard edition models).

Includes PLS-CADD/ULTRALITE, but does not include the terrain modeling, material or drafting functions of the standard edition and is based on the ruling span concept. Included at no charge with the standard edition ( compare editions ). PLS-CADD/LITE : Simplified edition of PLS-CADD for calculation of sags and tensions in a single span, thermal ratings and structure loading trees for a single structure. SAPS Option: Finite element sag-tension option: provides a superior alternative to the built-in ruling span sag-tension. Optimum Spotting Option: Enables automatic selection of structure locations and types for the least cost design of a line. Also includes PLS-CADD/LITE and PLS-CADD/ULTRALITE, but not any of the other items listed below ( compare editions ).

At that point you run the model and find out how many members are overloaded. All you need to do is Edit the Tower from PLS-CADD and the structure opens with the loads already applied. The standard edition of PLS-CADD is a line design program that includes all the terrain, sag-tension, loads, clearances and drafting functions necessary for the design of an entire power line. The export of the loads and weather condition from PLS-CADD to Tower (or Pole) is automatic.
