At 4:29 I made a mistake. I took 34mm instead of 30mm in a hurry so if you are seeing different dimensions in that part of the drawing that's good. If you need clarification about the direction of dimension lines, there are only three directions in the isometric view: 30°, 90° and 150°.
Turn Polar tracking on. There are different polar tracking(30,60,90...). Watch the whole video.I talked about dimensions in 'layers and dimensions' video. Also for 1*1*1 box dimensions are going to be huge. Set text height 3mm and make dimensions annotative so whatever the drawing is, however small or large it is we can just select scale and dimensions will automatically change.
@@compete2194 video starts at 3:30. All the things before that were to show you what is isometric view. You don't need to do any of that (except turning isodraft and polar tracking on).
@compete2194 those three lines in the bottom right just show these options in that bottom line.. When you see these options you need to click on them & when they turn blue (as you can see in the video) it means they are turned on. Sorry in the video I didn't show the part where I clicked on them to turn on.
