Drawing a 3rd angle projection and in model space I have made some lines dashed to show hidden objects but in paper space the lines are continuous. Can anyone help? Thanks

Hi
If you goto paper space view and click the model/paper button at the bottom of your screen and make sure it shows model. This will activate the viewport. Then goto the FORMAT menu and select Linetype. Next untick the box in the bottom left of of the dialogue box ((Use paper space units for scaling)). This will match your model units to paper space.
