Question about spline modeling in 3ds max

[Hiigara]

im still pretty new to modeling, and i am working on a car in 3ds max by spline modeling. anyway, i was wondering, after i create my spline network, and i apply the surface modifyer so that i have the patches created, is there any way to undo the modifyer after i saved it so that i can add onto my spline network? ive tryed just adding splines to the model like it is, but even with Snap turned on i still can't get the spline lines to match up with the edges of the patched area. im not too far along into the model so its no big deal if i have to start over, but i need to add more splines. if anybody can help me with some advice id apprieciate it.

I'd suggest you use the can to remove the modifier and start over... check out if this works for you, if no, place another post and I'll look for a better way...
Good Luck

Don't turn it into patch any more :)
