How i can modell a house in Inventor
Hi Eli it is very difficult to get a complete answer by someone regarding the building of a house...
Nevertheless what you need is to start with something smaller and much more simple to design... something like an object on your desk for example.
Also try the Autodesk Wiki for Inventor http://help.autodesk.com/view/INVNTOR/2014/ENU/
to become familiar with the most of the commands. Then step by step you can move to something more complex such as the house design...
My Opinion is to change software asap.
As an appropriate one is the "Autodesk Revit" http://help.autodesk.com/view/RVT/2014/ENU/
The most common for this kind of industry...
In case that you want desperately to continue with Inventor I can provide you this link... Matti Oikari
to get some ideas!!! ;)
