Why do RESICALC and SUBCALC take such a long time to redraw large models?
One reason is the amount of detail displayed with the model. You should turn off the conductor indicators in RESICALC and SUBCALC while you are modeling a very complex situation that contains a large number of conductor segments. This will help speed up the redrawing process that constantly occurs during the layout of a model. Once you have completed the model, and you want to print a copy, turn them on. Remember to turn them off again after printing.
