Working my way through this site’s Geo 101 tutorial I have come to a complete stop over the below described error. For some reason the 4th stave will not offset its two little tangent lines. I’ve been over the code as thoroughly as my brain allows. One reason this is so frustrating is that I have even download the example script from the page and still can’t find the discrepancy with I compare them. Next step is to restart the script fresh but before I do that: Can anyone identify the issue with stave 4? Thanks.
