N75 needs some arc definition, either an R word , or an I K combination. Don't know what else, as I've never seen "NLAP"

O i c, thanks ya..bt there is still problem for me, how to define the I and K or L(radius is more than 180 degree or less then). i had try many ways bt still yet cant get it..hw stupid was i..

[beege]

N75 should have: I0 K-3
N85 should have: I2 K0

Works for many controls. Hope it works for yours.
The I and K are arc centers' distance from the arc start point in X (diameter) and Z (length)
