I'm having trouble with viewing and printing linetypes in viewports. When I change the linetype in model space to a dashed line for example, it shows up as a solid line in my viewport. Properties shows that it actually is a dashed line, but it sure doesn't look like one. I have tried changing the linetype scale but saw no change in the viewport; however it does change it in model space. Hopefully someone can help the novice out here. Thanks!

Try Search as well for more responses. And if they did not say so in this thread make sure you do a Regen inside the Viewport to get the lines to update.
