spac is a good product with affordable cost.
we use both spac and eplan
the biggest fault of eplan is definitely the cost but as electric cad I prefer it (influenced definitely by the fact that I use it for several years).
from the point of view of graphic design spac is definitely higher since it turns on autocad platform while eplan is definitely very lacking.s
on the automatic management of terminals and connectors I would say that they behave well both, maybe eplan a bit more slender but a vote that you took the hand for me stays superior.even in the automatic management of the cables I prefer to the great management of eplan.I hope you have been a little help if you need however you will ask you will see that there will be also others that will help you.
