This tutorial is very usefull when you need to share a 3D model with a partner that has no 3D modeling software installed.
Inside Inventor choose open
Navigate to the folder your model is located. For this tutorial I will use my model "Wobbler Engine" in iam format. The same apply for step, iges and any other format Inventor can import.
After our model is imported we go click the Inventor icon (red arrow) and the drop down menu appears.
We go to export -> export to DWG
we choose a name and a location and click save
Lets see how our model looks like in autocad. We open Autocad (for this tutorial autocad mechanical 2012 is used. A standard version of autocad can also be used)
We click open and find our dwg file we just created
After autocad opens our file this is what our screen should look like.
Lets move it around a bit. In the ribbon go to View->Navigate->Orbit-> Free Orbit
As you can see our model is in full 3d.
Lets make a render out of this. Go to the Quick Acces Toolbar and choose 3d Modeling
In the Ribbon go to Render->Render->Render
After we wait a bit our rendered model looks like this. Notice that autocad automatically uses the colour style our model has in Inventor.
