Welcome to Autodesk Forums!

Hi,

Can you explain your problem in more details?
Do you see all lines in pink color in one of your old drawings?
Or everything is in pink color when you create new objects in the drawing?

If the latter, the reasons could be;

- the current Layer in the drawing has "pink" color assigned
- the current Color is set to "pink", but not to "ByLayer"

Can you attach sample drawing here?
