You will have to piece it together using different tools. There is an arc button that obviously creates and arc with a few clicks. You will need to get used to how creates the arc. It’s a little tricky… Then use the line tool to draw the rest of it. Once you have completed the layout, you select all the pieces and change the layer. Right click once selected and there is a drop down box to change layer.
