I have an assembly - in this example two frames.
I create a drawing, place a view and from this view define a Detail View.
Then I define centerlines from the Annotation menu and use the 'By 2 Lines' option, selecting the edges of my frames - the full length of the edges of the parts is highlighted and the resulting centerlines correspond to the full length of the edges, extending beyond the boundary of the Detail view. Why?
This is working as designed. We do not modify the geometry of a Drawing View as a result of the cropping boundary - we only crop the display. Trimming the geometry would cause other unintended results. For example, if you were to place a linear dimension, it would connect to both ends of the line and extend beyond the boundary of the detail view. If we were to crop the geometry - the dimension would be wrong.
To work around this, you need to select the end points of the centerlines and manually move them to the desired position.
