SOLUTION-1. There are many airplane models on the Net. Some are free, some are not. A fantastically detailed range is available (for a price) at www.deespona.com, simpler models at other sites. Also search the Net for seat manufacturers. Some give dimensions and photos, you can then construct your own seat from Poser primitives. By the way all Poser primitives are 10 inches in size to begin with - i.e. cube, sphere, torus, etc. SOLUTION-2. If the sample photo you have supplied is available to you, there is enough information here to construct a mock-up in Canoma which you insert your Poser people into. Does that answer your query?
