Improvement idea - Allow the end of the fiber fan out from a port to be moved to grid points.
It is very difficult to align the ends of the fan out portion of a fiber to a grid that is used to align fibers on the diagram. Many times it requires a short section of a fiber to be added to link it to the grid which then blocks the automatic placement of a label for the fiber. https://www.ptc.com/en/support/article?n=CS283485 'Warning "Fiber segment is too short for fiber W-# to correctly display label." when changing the label location in Creo Schematics'
Unfortunately, the proffered "solution" is unworkable. "Workaround- Modify the fiber to increase its length so that label can be displayed" Doing that either requires that the main part of the fiber be kept off grid to the location the fan out creates or that the short, odd angle, extension be lengthened to take up much more space and put the label in an awkward location.
The only real work around I have been able to find is to create a label elsewhere along the fiber and move it into the desired position. This runs into another "the program is working as designed" issue. If a label is moved, it no longer is considered to be part of the fiber. If you select the fiber (which visibly selects the label) and change the label, it will ignore the change because (in spite of it showing as selected), it is not selected for editing.
