Creating an airplane canopy

[co-capt]

I am trying to create a canopy for the aircraft pictured below.  I have tried everything I can think of, but it doesn't come out right.  I can get the general shape, but I would like to add a little lip in the bottom towards the inside and A tab at the front to go under a lip on the fuselage.  The front doesn't seem to mesh well and there ends up being a hole in the vert front and it looks like the canopy dips inward almost like an elongated dimple

I am trying to print this with a single .4 outer perimeter.

Draw the section of the tab on centre line and sweep it around the base of the screen, does not need to be very long.

Might help....

post your model (export as .f3d to computer, attach at bottom of reply) if you want some specific help.

I'm going to guess that you've lofted to a point profile somewhere causing funky surface quality.

For this loft you need 2 rails. Maybe something like this?

This is about as far as I can get.  not sure if I should loft it as a solid, or what planes to loft from and to.  The canopy turned out ok, but it hangs over the airplanes and the front and back come to too sharp of a point.

I would use loft instead of sweep.

I changed the design so that the canopy halves are tangentially connected.
