Getting rid of fat lines in a Sketchup section images

Something I have not figured out. The heavy lines in images produced by the section tool a problem when transferred to Layout. Is there a way to make them less thick? This may be rudimentary, but here I am. Thanks

Edit the Section lines in the style edit tab. Change the weight to something less to suit. The setting is under the Modeling properties. Remember to click on the thumbnail to update the style and save the change.
