Hi sir/madam,
how to create a new component footprint. For ex: Ft232rl ic it is a ssop package. How i wanna create footprint for this.
 

hi pavan,
1.create the Pad using Pad Designer;{Pad size is 1.47mmx0.3mm or else convert in mils 58 milx12 mil}
2.open the cadence allegro-->file-->new-->package symbol {select} then save footprint name as ssop-28pin
3.assign the path of library using setup-->user preference-->path-->library then select the pin, using Logic-->pin
4.keep one by one in Pitch 0.65mm

hi,
for adding etch select the shape-->pologen or rectangle and choose the class as Etch and subclass as TOP from OPTION TAB.after that select the assign net option for shape and draw it
if you want to edit select shape-->select shape click on the shape you can edit or move the shape
