i am simulating a simple roller coaster om curve ramp but can not make a 3d curve
all the curve that i made is on the plane. tried spline but could not figure out how to draw a curve out of the plane.
please help me.
try freestyle module in shape design. there is 3d curve. but in other surface modules you can also do this with combine command.
i am not good on them as i am a novice for pat and product design module only.
i would appreciate if thee were any tutorial.
