I am a beginner and I am trying to follow this tutorial
First I made a framework which you can see underneath the design. Then I connected the dots and made the design. The corners of the lines are broken until I join them with the CMD + J function. The problem lies in the centre where this doesn't work. It either adds extra lines (connects the wrong dots) or it stays broken. How would you approach this? How to turn all the separate lines into one line.
