Reading Survey Measurements - Page 2

I have a question for you surveyors. Are property line distances measured as the crow flies? ie, in a straight line regardless of terrain elevation changes?

Yes, just like looking at your property map. When I worked in Alaska we measured distances, miles at a shot, we had to figure in the curvature of the earth though.

Oh, I could tell you stories about architects....... Strange breed. Especially my ex-sister's hubby. When he switched to cad, he used to erase the auto-dimensions and 'hand draw' them. Adding across the plan, rooms+walls never equaled overall dimension. I once had to model a 3-d roof over his plan to show him what he drew wasn't possible to build.....

there are two types of Countries..those that have been to the moon, and those that use the metric system

In survey you just use miles, feet, tenths and hundredths of a foot so it's pretty easy.

That's funny since the earth is flat.

Agree.

Poor CAD discipline has ruined the industry. CAD makes it very easy to do a bad job.

When I toured the Frank Lloyd Wright home/school in Arizona I noticed a lack of cadd stations and an abundance of drafting tables.

Seems Frank felt you should learn proper drafting and design on a board before getting on a computer.

I came from a traditional drafting background learned on a table using lead and ink. It is hard to teach that on a screen.

My argument that cadd is better is the fact that if you let it do its job, it will make your easier and there will be no mistakes.

What his BIL was doing was idiodic, he was making errors where there should be none.

Back in my yoot I was working on a new construction job installing a steam turbine and generator and was using a transit to shoot in the elevation of the sole plates to within a few thousandths of an inch.
The pipe fitter foreman asked if I could shoot the elevations of some piping supports, I looked at the print and said to what tolerance?
He said huh? I said how precise do you need it?
He said oh we need em dead nuts, within 1/4"

What????

Wright died 10 - 15 years BEFORE architectural CAD existed. There was NO CAD when he was alive.

Take it up with the school, I noticed no cadd stations and lots of drafting tables, commented on what I saw, the tour guild said that.

I never stopped to think about when he died or if there was cadd then, it made sense to me, it reminded me of how Adriane Newey designs his cars on paper before committing them to cadd.

Maybe it was more of the philosophy of the school rather than Franks wishes. I did find it interesting and agreed nonetheless.

Frank Lloyd Wright (June 8, 1867 – April 9, 1959)

Yeah yeah, sitting in front of a computer helps, I did not bust out my phone and google Frank in an effort to put down the tour guide, I was just repeating what he said to me, maybe I mixed up some words, maybe it was more like if Fank was around today he would never let his students go straight to cadd, he would have them design on the table first.

Maybe that was the gist of what I remember from the tour, sorry, I am not Kachi, I just ramble some **** out sometimes and carry on the conversation without doing 10 hours of internet research prior to my comments.

I see dimensions like that all the time building houses. Nothing is that accurate when framing.

I didn’t read all the posts, but why are survey dimensions is feet and 10ths of a foot? Is it just easier than fractions? I can see that.

I can tell you that our civil engineer's surveys are accurate to a tenth of a foot. I've been building stuff with him since 1992, and we have built projects that cover a few thousand linear feet.

Civil engineering surveys are always in decimals out to .01 foot. But if you think that is confusing, try reading a topo map or a grading plan, haha!

so every ten feet the guy could be a foot off, that's not accurate. don't want to buy anything he surveyed.

Here is a shot in Alaska, when the helicopter flew in here we scared off a bear, it left a a pile for me there. I don't remember how high this was but it seems like a couple thousand feet up. I turned angles and measured distances sometime over four miles. One of the points was four thousand feet up with just enough room for the helicopter to hover a bit and let me unload the gear.

That's cool. I doubt you could afford it anyway.

In reality, his stuff is crazy accurate. All of the subs say his stuff fits better than most, which is nice when you're working with multiple easements. That's when it gets scary, or with multiple utilities.
