I know i'm being impatient, but i'm trying to get up to speed with AC3D as quickly as possible. The problem with youtube is that the role of the ipacs exporter and library objects is crucial. At this stage i don't think i need to learn all the ins and outs of AC3D to get a tower and runway in. Mastery of modelling can come later. Rodeo is producing great videos but that will take time. 'experts' in general tend not to realise what pitfalls a newbie encounters, so i'm inviting others who are right at the start of learning AC3D for the specific purpose of creating an airfield to share their learnings. I'm assuming you have already:
1) Downloaded the sdk and installed the converter
2) Downloaded the 'make your own airport' and successfully added another library object to kdwh
3) Seen Rodeo's video on starting a new airfield and adding a background image, sized to your airfield
If you haven't done these steps yet, i'd recommend you do. If you have done this and got further than me then please share.
