Aircraft build - Engines

Create tube - align with front part of engine - turn into editable poly - shrink front and back to generate smooth curve

Trace profiles from outer engine / back of engine from reference planes - Turn into editable poly - Use lathe technique as before (360') to create pieces to slide together

Move into position and align with reference planes to check for accuracy
Slide into over lapping positions to create engine base

TURBINE

Create tube - thin with hole in middle - take measurements from reference planes - Lots of sections required

Turn into editable poly - Remove all geometry except single segment - Select boundry on open segments and select cap

Twist outside geometry

Select tools - array - change appropriate boxes to produce 30 blades overlapping over 360'

Add cone to centre to give impression of  turbine blades + turbine
