How to delete yellow and blue sketch lines?

[Anonymous]

 My building is showing yellow and blue sketch lines (mostly yellow)... how can I delete them? So none of them will show, it would just be my building.

Right click on the sketches in the browser and turn off Visibility.

or

go to View tab and on select Object Visibility down arrow and unselect 2D sketches.

or

select each of the unconsumed sketches in the browser and hit the Delete key.
