AutoCAD Map 3D

[#1]

Attached is a drawing containing a big rectangular lwpolyline and two relatively small lwpolylines near the drawing origin. One of these smaller plines is on a layer that has a dashed linetype assocated with it. That layer is also red. When I zoom in on that pline, however, I won't see the dashes unless or until a regen occurs. As of this writing, after trying a few things, I'm almost resigned to including a note telling the client they might have to REGEN in order to see non-continuous linetypes display properly. Any ideas?

I guess 'cause your LTSCALE is too low: check the attached file out.

When I open the drawing in the zip file you attached, I get the same behaviour as  the drawing I posted. When I zoom in on the red line, it appears continuous. Once I regen, it appears dashed, as it should. Do you experience something else? I am using release 2010.
