I am currently working on the expert set Sydney Opera House on LDD and I am stuck at a certain step. Would someone please help me with the next few steps. They are quite difficult and I cannot figure out how to connect them. I am stuck in Book 1 at step 28. I have attached the LDD file. Thanks in advance.
