Drawing in 3-d?

If I'm understanding the intent correctly then the bottom view is about correct minus how you're planning on attaching the center cross members to the base structure and how they attach to each other in the center. If the crossmembers are angle cut to sit flat on the bottom board and to each other then you'd need to know the cut angle and resultant hypotenuse length of the cut, temporarily sketch that as a line in the bottom view to establish a "footprint" (rectangle) on the bottom board and meeting point in the middle then project the corners of the footprints up to the front view.  In the front view you'd see three edges of each cross member; the "width" as seen in the front view is actually the hypotenuse from one corner of the footprints rectangle to the other.

Clear as mud?

actually almost exact 



I was looking at it earilier today, and thought to myself, "Damn, this is going to take some trig." 

I flunked horribly in highschool, I've been trying to work some simple problems this afternoon, but about an hour in I realized that my drawing in isometric scale doesn't have right triangles and so the numbers were all wrong....

Ive torn up about 10 sketches  so far

getting a little better.

ahh its a blackhole to doom!!!!!

get rid of the graph paper. maybe thats whats messing you up. Go buy a roll of vellum and draw on that. much nicer paper.

It looks like you have a hard time with the angles like you said. One of the first things i did when i first started drawing isometrics, is to draw a plan and a elevation drawing. plan on top, elevation on bottom, and then draw guide lines from the top to the bottom, and from the right to the left. Where the guide lines meet is where that point will be.

Another thing to note is, nothing ever looks completely right in isometric in real life the line further away is always shorter to the eye. So dont be confused when it looks stretched.

I drew an oblique of your stand, want me to upload it once i get home tonight?

Sure that would be great

My shading got pretty much lost in the scan but oh well. I went w/ square legs instead of rectangle and inset the sides of the drawers a bit to give the face a bit of variation. Since your original orthographic wasn't consistent I opted to use dowels since they're easier to draw.  I'll let you figure out have to join the dowels though.  Oh, there's an extra line on one of the braces. I was tired.
