What are your tips & tricks for my field coding to get these 3 point curves to lose the bubble effect:
and instead to get the curve to look more like reality (like this):
?
Thanks!
Heading to our friends lake house for the weekend. Taking the laptop along since this topo is due Monday. But I am looking forward to the change of scenery, and slower pace.
Have a great weekend!

Break the curve up into two curves in the field
The basic problem appears to have been that the End of Curve shot wasn't actually on the end of the curve. The easiest way to avoid that is to take a piece of chalk and mark the actual beginning and end stations beforehand. That way, you can stand back and eyeball things.
I would have broken it up into 2 arcs, with the middle shot being at the "nose" of the island.
agree with the others. often a curved curb or walk isn't a single simple curve. we break them up into two or three compound curves when in doubt.

Yup. More shots usually help.

I cannot get that link to work bro.
Take out one of the HTTPs in the link. Then it works.
He is referring to the one point curve command in C3D. I've stayed away from using it myself, just on general principles (because as mentioned before, most things aren't simple curves), however, it looks like it would work for certain applications, assuming you verify it definitely is a simple curve.

Why does it have to be a 3 pointer? I use the Carlson F2F "PC" to start a curve at or near the PC. If you don't use a "PT" on the same code, it will draw a 3 point curve, but if you do use a "PT" code it will draw a very nice line using all the points available (4 to infinity).
'cause "some people" are still spending all those bucks for Civil3D and haven't learned any better yet. 😛

touche. Still should be shot at closer to the actual PC though.
I agree about more shots. Have you ever watched a crew build curb? Could have been built like that.

That is the ticket. Thanks man. I forgot about that option.
it's not a 3 point curve. you need more shots...thats it.
IF you shoot the actual PC and PT and nail down the POC at the center of the radius, a 3 point curve routine will work just fine. Otherwise they will look really tacky.
I like more than 3 shots simply because I am usually doing topos and I like more shots for the elevations.
If the curves go all nasty I use the "Draw arc by start, end, direction" in my Carlson Survey to fix how it looks and fix it all up. (You CAN spend too much time shooting curb curves sometimes.)
