Linetype Trouble

[corvette63]

I am running CAD 2000. I have CAD survey data that has existing trees on the drawing. The trees are showing up as a d instead of the tree canopy. Tried everything that I could think of. Please help.

Are the trees maybe xref's for which the path is no longer valid? Are they blocks that have been since redefined?

Problem was did not have symbol checked in the properties block. Now having trouble getting my linewights to show thicker. How do you get actual linewights to show?

Polylines with thickness show different lineweights on the screen. Otherwise, lineweights do not usually show except in plotting. There may be a setting somewhere...I'll look for it...
