AFCAD Question

[ivormills]

I have used afcad for some time with great results, and have recently been working on 'new' airports. After positioning runways and taxiways, I have laid a 'grass' polygon to enclose the whole area and then drawn apron polygons on top of this.
I now find that the apron polygons do not show up. Is this because afcad does not support layers or is it something else I have missed?
If it is the former, can I flatten my airport area and add a standard fs ground texture over the area and then in afcad just add my apron polygons and if so, what is the best way to do this?

Many thanks

I've messed with that question for some time with varying results. Think I may have stumbled onto the key...

You must pick the surface for your 'apron' apron from lower (farther down) on the surface list than the one your using for the 'airport poly' apron surface.........for example, you can have asphalt on grass but not concrete on grass......at least that's my conclusion..

You must pick the texture for your 'apron' apron from lower (farther down) on the texture list than the one your using for the 'airport poly' apron texture.........in other words, aprons are 'layered' in reverse order of their position in the texture selection list......at least that's my conclusion..

Yes, Ivormiils, that should work.

I've modified my 1st reply to make it a little clearer........I think...

Many thanks Dave, I will not be able to try it again before the weekend, but I will let you know how I get on.
