How do I turn off the transparent view/phantom lines?
Without seeing the model a wild guess it is back edges, toggled with the “K” key.
Maybe you have inavertently set Back Edges on. Click again on yje icon to turn them off or, press the K key that is the shortcut for Back Edges.
If this is not the problem, posting an image or the SketchUp file (if it is not too large) is going to help us help you.
Use the eight icons from the left to upload a file or drag the file icon in your new post.
Good guess, that worked. Thanks
toggle with K key that is.
