# Microstrip line simulations in Momentum

Hi, i would like to design microstrip lines that have the same physical length but i also want them to reach a common vertical limit so i have to bent some of these lines. Does anyone know how to calculate the length of a bent line? For instance if i construct a line consisting of parts using the curve model of momentum with pi/2 angle and some radius how can i calculate the length of these parts to control the overall length of the line??
