Solid line not being changed to dashed

Hi

I imported a file from ai. as dxf. Now, I want to change Solid line into dashed line. I tried doing it with properties, checked its scale. But it is still not changing.

Pls help.

Thanks

Has the drawing imported in at the right unit scale i.e. metres imported in as milimetres making the lines so small dashes at your regular scale won't show up.

Post a copy of the drawing and someone here will take a look at it. We don't need the entire drawing just the portion with the line(s) you are trying to change.

Change the LTSCALE-variable til you see your dashes. Try really small as well as really big numbers.
