How to create a simple racking system Step 11 All racks and aisles in each block are automatically connected to each other. Do as per below if you must manually connect some racking and/or aisle. Click on the connection tool (Connect two zones) on the lower tool bar. Then first click on the 1:st aisle or rack and then on the aisle you want to connect to. Do the same thing for every rack or aisle. You have to click on the connection tool first for every connection you want to do. This is to avoid that elements are connected to each other by mistake.
