Hello. When plotting layouts with viewports, obscured edges (ie. hidden lines) plot nicely when we use a drawing frame setup in inches but if the drawing frame is metric and the unit is mm hidden lines plot with very long dash. We set variable OBSCUREDLTYPE = 2 for hidden. Is there a way to fix this problem. Thanks in advance, Santos Dizon CAD Coordinator Jaako Poyry ABGS Montreal, Que.
