Ok revenge I know a very easy way to draw. First you make a compass on the top of the paper , but you add a up and down line and rotate your normal compass... 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.... 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. 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. When I practice I always put north on one of the top sides of my compass...draw a main then any branch lines . All lines will be parallel to one of the compass lines after branches draw risers witch will go up and down on the paper . And draw fitting directions like a wye or combo and San tee. Then draw vents in dashed lines. Its hard to explain like this but I tried. I ways amazed when a was shown and drew a lot to practice for my test. But wasn't required to draw for test just drew to make a parts list for the doll house Don't hesitate to pm me if you want more explanation ..... Here's a crappy drawing with out fittings but the compass is the key for this method. Jut draw all lines to mach it and you will end up with a 3d drawing

Thanks tex helped out a bunch i heard for the master you no longer play with the doll house. but they do want an isometric so i gotta learn how to do and if they do make you play with the doll house gona be kind of hard to do with out knowing how to draw an isometric. Gots to start learning quick btw. When i took my journey man i did a basic drawing for drain, basic for vent and passed it fairly easy. but the master i heard its 26 fixtures. I dont think my way gonna work this time.

Is his website. I strongly recommend him and will be taking his prep class on 2 more years

Isometrics are not that difficult once you get the hang of it. You will need to practice.
All vertical pipes such as waste stacks and vents, are also vertical on your isometric paper.
All horizontal pipes are drawn on a 30 degree angle on iso paper.
You need a '30-60-90' triangle in order to draw isometric drawings. You'll also need isometric paper.
