I have drawn a series of centerlines in a view of a part that I want to use for dimensioning.  But I don't have them attached to the view correctly because it won't let me select them to use for view.  If I double click outside the view then I can select the centerlines but then can't select the part object to complete the dimension.  Is there a way to reattach the lines to the view so I can use them to dimension?  I know I can double click the view to select the view and re draw the lines, but surely there must be a faster way. Thanks.
