uhh.. i think kapil is starting from scratch...
and i mean he's starting from no knowledge of Maya what-so-ever...
because if he had some knowledge then he'd know where to start...
to give a basic outline, from what i've picked up from all the video tutorials and html tutorials, you start by importing image planes (i gather the site arran directed you to is perfect for it)
then you use nurbs to get an approximate shape of the plane exterior
then you convert to polygons and get it closer to the shape
then you switch between poly and sub-d to get detail and textures
other than that, i agree with arran, if this isn't the answer you're looking for please reword your question to be more specific
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
