That's 'normal' AutoCAD behavior. A drawing template (.dwt) is used to pre-set and store:
For more follow this link: http://docs.autodesk.com/ACD/2010/EN...0acaf-78f3.htm
- Layer names
- Title blocks
- Snap, Grid, and Ortho settings
- Annotation styles (dimension, text, table and multileader)
- Linetypes etc.
Background color in thumbnail doesn't matter. When you open any of the others templates the background color will be the same color as you have set in AutoCAD in your current profile; it doesn't change with different drawings. It's user's setting.
The way the drawing opens in Model or Paper Space depends on in which space did you save your template.
Any queries... don't hesitate to ask.
