Hello Im new to making parts with Guided Loft or Boundary Boss. Ive been toying around with trying to make a propeller but Im not having much luck. Everytime I try to go into the blade of the propeller with the Loft, I get an error that tells me the guide curve is invalid. It lofts without the guides but it wont work with the guides...Not sure what Im doing wrong. Any guidance is appreciated.
