@paden-cash When I first started surveying I heard a story about a surveyor (engineer?) who laid out a house parallel with the lot lines at the required setbacks: 25' in front, 5' on each side. Two stakes at each corner on the outside lines prolongation.
The foundation was poured, the framing completed, the roof built and the drywall installed, but the cabinet maker couldn't fit the pre-built cabinets into the kitchen even though the dimensions were exactly per plan.
Seems the lot was not 90° (surprise, surprise), but more like 88°±, just not enough to see the difference with the naked eye. And it took all the way to the finish carpenter to find it when it should have been caught by the surveyor(engineer?) And it would appear that nobody checked the diagonals.
The biggest mistake made in staking structures is not checking the diagonals. I've seen it many times. ????
@flga?ÿ
I can think of a situation where the diagonal measurements are equal, but, the structure is not "square" and it happened to me.
?ÿ
Yes, it could. I always stake buildings radially, then check diags, and pull from house corners to lot corners. Then close the setup into two other known control points. ????
@not-my-real-name Yep, trapezoids will do that to you.
I have interviewed my fair share of office & field applicants. Our office applicant form contains only bio, education & immediate past employer, if they want to include it. For office CAD positions, after the initial get to know you conversation, I have them sit in front of the PC & tell them to process some contours from an XYZ file or fill up some CAD title blocks with basic data. Those that know what they are doing would go straight to it and ask some basic questions about menu items if they are not familiar with our CAD version. For field crew positions, we just ask them to set up a tripod using an old instrument (in case they drop it accidentally) over a point that is a bit difficult to occupy .
That's basically it. Those career objectives are BS if you ask me.
It worked well in the '80s.
Still does. ?????ÿ
Huh?
Equal diagonals of a trapezoid, for instance.?ÿ If there are errors in the side lengths of an intended rectangle, you can still get equal diagonals. But not in a figure resembling a parallelogram unless the sides are really weird.
Edit: can't spell this morning.
@mathteacher think of an isosceles trapezoid. Like an isosceles triangle with the top cut off.
?ÿ
@flga not a parallelogram. The diagonals would not be equal.
Yes, the magic word is isosceles. This being a spelling thread, where the pickiest of the picky reside, I thought I'd be picky, too.
The fallibility (abuse) of spell and grammar checkers and the combination of the two, is rife in the media down this way. Here's an example:

Did I miss any others?
