Dashed lines

How do I make dashed or broken or dotted lines? Thank you for your help.

In SketchUp Free you can right click on an edge and use Divide to break it into a bunch of short segments. Then you can erase alternate segments.

Instead of erasing the alternate edges you could hide them.

If you are wanting to show hidden features in your model, you can press K to turn on Back Edges.

[K] by default is to show (toggle on/off) ‘Back Edges’, edges that are blocked by faces in the current view.

To show (toggle on/off) hidden geometry one should apply a different key combination, for me that is [Alt][x] as a shortcut.

I did write hidden features. That’s not the same as hidden geometry. Having a shortcut to show/hide Hidden Geometry is good but it won’t show hidden features like mortises in table legs.

Excellent! Thank you so much for your time and thorough response.
