![]() ![]() I ways amazed when a was shown and drew a lot to practice for my test. Its hard to explain like this but I tried. And draw fitting directions like a wye or combo and San tee. ![]() All lines will be parallel to one of the compass lines after branches draw risers witch will go up and down on the paper. When I practice I always put north on one of the top sides of my compass.draw a main then any branch lines. If drawing a sanitary drain system you put a line with a S on the edge of the paper to represent the sewer and where your drain will run to So now you start with a main trunk and what ever direction it goes in the building you draw it parallel to the line in the compass for that direction so a riser or drop will always go up and down. Now you have your compass and north can be where ever you want it, it doesn't matter at all But if you are drawing for a real job I'd make it match the site plan. It sounds stupid but it works when you draw the east west north and south you draw them at a 45 degree angle some say 30 degree but ether will work for a starter drawing. First you make a compass on the top of the paper, but you add a up and down line and rotate your normal compass. ![]() Ok revenge I know a very easy way to draw.
