while creating a part i want to use pattern in pro sketcher mode it is possible or not
Answer is quite simple... you can't
ProE is manly focus to use pattern of the features rather than pattern inside sketch.
Walk aroud is simple Ctrl+C, Ctrl+V of the features.
You can't use Pattern commend in sketcher, but you can surely use mirror command (by drawing construction center line) to do pattern.
Its all up to your creativity & imagination to get pattern...
if u r work in part module that time u make a sketcher pattern in sketcher mode..1st make a sketch and after select pattern u done a pattern..
use geometry pattern :)but u need to come out of sketcher mode...then you can patter your sketch easily
creo 2 can't do it
