Hello I´ve just started to work with PLS CADD, I´m having a little bit of trouble, and I´d be really grateful if someone could give me a hand. I have got cartography, towers´ models, described extra-cost & prohibited zones and already defined criteria and now I´m trying to use Optimum Spotting. We are simulating a double circuit line but when I run simulation I can just get a simple circuit, no fibre line and no grounding cable.

Design and Optimization of Overhead Transmission Linesusing PLS-CADD and PLS-Tower Software Theoretical and Practical PLS-CADD tra.

What am I doing wrong? Because to simulate optimum spotting assigning differents towers it has got to take into account 2 circuit and fibre´s forces.

Thanks a lot RE: PLS CADD (Structural) 9 Feb 13 00:26. I'm a structural guy and we don't use optimum spotting but from the demo I saw a few years ago the O. Hierarchy In Software Company Designations. S. Algorithm only looks at ground clearance over the terrain and does the spotting to find the lowest cost for a line. I don't believe it takes the strength of the towers into account when doing O.S. The towers have a wind and weight span specified and the program picks the cheapest set of towers that make up the line.
