Beautiful. If I can take away just one nice, simple rule of thumb for the shop from a thread, then it was worthwhile. In this case, it paid off double. One excellent tip from Leon (Thanks!) and a whole lot of entertainment. :-)

BINGO!! Swish! Nothin but net Doug. LOL!
Yeah, I thought about that when I originally posted. A straight pentagon planter is downright ugly.
In defense of the CAD program and drafting in general, in the old days when one used a pencil and T square to draw, the "rule" was to not "over" dimension. Over dimensioning would be showing a dimension for every line or object on the drawing from more than one reference point. Proper dimensioning requires the person reading the drawing to do some math on his own to properly interpret unknown distances. For example, a line is 2" long and another line intersects this line .25" from one end. Proper dimensioned, the over all length of the line is shown and only the distance from only one end of the line describes where the intersecting line is located. Either a dimension indicating the intersection is .25" from the end of the other line or a dimension indicating 1.75" from the other end of the line is all that is required. In more complicated and detailed drawings this is not so cut and dry. The person reading the drawings should be able to interpret the drawings and to handle his end to make sure that the results are a reflection the drawings. This is probably much like a pharmacist that is able to read the prescription from a doctor. The patient normally has no clue as to what the prescription really says. This whole thread is a good example of why knowing how to read a drawing is essential. Full sized plans should not be needed by any one to understand a properly drawn and dimensioned drawing. CAD programs if anything have let some draftsmen become lazy or sloppy as it does eliminate a lot of thinking on the draftsman's part.

Imagine full sized plans for a house, sky scraper or a highway from the east coast to the west coast.

Yeah but..... ;~) He indicated the use of a compound miter saw. I took that to indicate that he wanted to know what to set that saw at. Had he indicated a Skil saw or jig saw, the 54 degree angle would have been correct.
Yes exactly.
Well for those more challenged with the geometry rules... ;~) I always go for the saw setting angle.
If you want a square or rectangle, add up the amount of cuts necessary. 8,
2 on each end of each of the 4 boards. Divide 8 into 360, you get 45 degrees for the saw setting.For a 6 sided project, 12 cuts divided into 360 gives you a saw setting of
30 degrees. The resulting angle would be 60 degrees on the end of each board.Bob I betcha you are totally confused now... LOL... I hope you recognize the correct answers.
That is when you let the computer miter program earn its spot. ;~)
I hope Bobs wife does not change her mind and go for a 6 sided piece... ;~)
The real fun comes when he cuts those angles and finds out what "incremental error" is all about. :)
"incremental
Not gonna happen.... ;~) Way too much detailed advice given that would prevent such a thang.
This has been fun. I cut using the 36 degree setting on the saw and it turned out perfect,but as someone stated a couple of posts back, it's gonna be ugly alright. No, I won't quit my " Day Job ".
Thanks again for a very entertaining thread.

I sit totally stunned that so many people could work so hard at misunderstanding each other.
Jeez Paul, how long have you lived? Isn't that what entire countries have done since man has been walking upright?
Good point. I had hoped for better for people who aren't scum^H^H^H^Hpoliticians but I always do seem to be overly optimistic.
Well it s been fun how many different ways can you say Potatoes. I guess this is why these forums exist . It was nice NOT to see all kinds of name calling and just a good exchange of different points of view for once.

Actually, Complimentary angles add to 90 deg. Supplementary angles add to
180 deg.
Say Bob, aren't you glad you asked?

Swingman responds:
Ah well. My Bosch 4412 has a 52 deg. left and 60 deg. right setting.
Angles confuse me easily. I probably spend more time working out angles than at any other single woodworking chore.
But my math is abyssmal and always has been, which is my own fault for daydreaming through the appropriate classes, something I am now trying to pound into a 14 year old granddaughter's head. She's excellent an English but won't study math "because I'll never use it." Amazing what a difference in perspective one gets 51 years later!

Easy. You just cut the bottom at a different angle. Right? ;) Let's see, it would be 54 - 36 x 360 / 540.
