At the Top Left of the Window you should see 'Material' and 'Appearance' to the left of each of these boxes are round icons. The 'Pizza' icon to the left of 'Material' is the materials editor button and the rainbow coloured button to the left of 'Appearance' is the Appearance editor button.
If you don't see these, they may be switched off in which case, click on the small triangle beside the cross and select, Materials browser, Materials etc....
I have all those active but i cannot seem to get any of the materials and colors in the Styles Editor (manage tab).I attached another picture (2a) of what i have available in my Style Editor.I found a picture on here of what i want the Style Editor to show (2b)
The manage tab is no longer used. This is part of Autodesks revamp of the Materials and Appearance handling in all Autodesk products, to make them more compatible with each other.
If you are thinking that the job is only half done, don't worry, you're not alone .... lol
You will find that the materials and appearance styles have been moved, they are no longer in the 'styles' editor. Instead, look to the quick access toolbar (top left of window). To the left of the 'Material' textbox is a pizza like icon, that is the materials editor. To the left of the 'Appearance' text box is a rainbow coloured pizza icon, that is the appearance editor.
Be prepared for more surprises
In Inventor 2012 you were able to edit the scale of a pattern (ie Expanded Metal) in the "Styles Editor". Now you only see "Lighting" as a editable option. Is there any way to edit the scale in Inventor 2013?
The way to change the scale of a texture is as follows:
1)click on "appearances"
2)find the material you wish to edit (ie Expanded Metal 02)
3)double click the material
4)under "cutouts" to the right click the arrow & select "edit image"
5)under "scale" you can input the required scale
