Extruding the frets

- In the last video, we set up a new part of our algorithm…that defines the lines for the fret tracks…of our musical instrument,…so those will be the locations for some…shallow grooves and the wooden base…where our cylindrical metallic frets…can kind of sit as the instrument gets sandwiched together.…In this video, I'd like to make the extrusions…that will represent the actual frets,…so we'll some extruded cylinders…that sit along those lines and that are the same length…as the instrument's wooden top.…So, in Rhino I'm working on the file…instrument-setup.3dm…and in Grasshopper I've got the file…0050-instrument-fret-tracks.gh…and we'll work on adding this step…to make the fret extrusions.…

So, looking at our current design,…you can see I've got the wooden top here,…that's the smaller rectangle,…then I've got the fret tracks above it and below it.…So, what I'd like to make is a line…whose left side is in line with the left side…of the wooden top and whose right side is in line…with the right side of the wooden top…
