Autodesk Inventor

[#1]

Newbie to Inventor, I'm trying to assemble some part drawings I have made so far. In the Help file it states "On the ribbon, click Assemble Tab > Component panel > Place".   My problem is, I do not see an Assemble Tab on the Ribbon, nor do I see a Component Panel nor a Place button. HELP

you can not do assemblys in inventor lt

The suite compare sheet shows that you cannot create large assemblies.  It doesnt say you cant do any at all..!?
