up in the top left of the tool options (depends on the version, but it should be a tab in the top left of the screen) there will be an option called feather, just increase that to adjust the amount of "feathering" or softening of the edges.  takes a little tinkering to get it just right, but that's how it's done.

i good set of wrenches or a skill saw or maybe a good battery operate drill. the drill is handy around the house because you can use it as a drill or an electric screw driver

Well as far as a formula i can't help you there. i just happen to own a program that allows me to draw perfect shapes of any size and diminsion them accordingly (auto CADD). and at the top of your 300 ft house, or where ever it is that your measuring from the horizon at sea level is a tad over 21 miles away (21.20389 to be analy exact). first you must know the the earths circumfrance (i know i can't spell) which is 20,890,637 ft, next you have to know the distance you are away from the earth (which you do, 300 ft). now you have to know the formula for finding a line that intersects your hieght and crosses tangentally across the earths surface. know you have your triangle and apply the Pythagorean theorem. you have an answer.

if its somewhat large, or near something very important, i would recommend going to a local geotechnical/ civil engineer.  \n\na few hundred bucks may be worth it not falling over, and then you are out the wall and the money.  better safe than sorry.\n\nan engineer will review site and soil conditions to give you a quality end product, and a guarantee

Try the Sheetmetal Contractors Association  its somthing like SMACA .\n\nFabrication is not the hard part.   Laying out the various fittings may be more than you want to do.\n\nThere are software packages available that will do the layout work for you but all I've seen are pretty expensive.

A lathe, a drill press, and a milling machine would be a good start, although how you plan to use them when you don't even know the names for them is a bit of a mystery to me.  Try Harbor Freight or Northern Tools.\n\nhttp://www.harborfreight.com/\nhttp://www.northerntool.com/

If you are using Windows, Paint is the best way AFAIK. Open Paint and then under Image select Stretch/Skew.

Since you don't want to subdivide (subdivision with chi-square is perfectly valid BTW) you could try a Tukey's HSD. However if you are doing this by hand it will probably be faster to subdivide.

I wouldn't attempt it unless you can level the ground. Trying to put blocks under the legs is a recipe for disaster.
