So, just when I allow myself to feel I am understanding Auto Cad and getting to grips with the tools, straight lines throw me a curveball( excuse the irony!). I started this exercise around lunchtime (between errands) and got a little stuck at the central lattice piece. After returning to the exercise I have needed to delete my lattice attempt a few times now. I thought these straight lines would be easy! After trying to construct this initially with a serious of lines, I found a tutorial showing the pattern being constructed using the array tool. It’s taken me further failed attempts to realise that when adding spacing dimensions I need to account for the shape side length, as well as the distance between the shapes. This should now be easy !!!!! I will post the finished result when done. I can not believe I have puzzled for so long over something that I feel is extremely straightforward!!!!
