Not sure why but when I printed out the pdf the legs in C1 and C4 extended down past the end of the grid making me think they went down to at least R9. After thinking I screwed up twice I went and looked at the solution and saw that wasn’t true
I can’t replicate that error in our PDF viewers but we’re sorry you ran into that trouble.
9:04. Strange that I faced the exact same issue as Jack but fortunately, I saw his comment before I started solving.
How were you viewing? Web browser + PDF viewer embedded? Which one? As a file?
As a file ?! I clicked on the PDF link under the image above.
From what browser? Chrome? Firefox? Does that use an Adobe Acrobat plug-in to view PDFs?
I’m trying to know the software you viewed to see if I can cause the PDF problem again which will let me update the file.
Sorry for the late response. It was from Chrome. Yes, it uses the Adobe Acrobat.
