I get it. I've taken a few approached to the whole F2F process.
Somedays I feel like im drafting With a 2m rod.
Other days it sometimes feels like I'm lugging around a 15lb toilet plunger...... ??? ?????ÿ
Ok and as for general practice how does it go? So lets say i need to complete a line that consists of 4 points i go with code +7 and then the code for the rest 3 points and thats it? And then for a new line on the next point i give a new "+7"? Isnt there an end code (The new beinning signifies the end of previous segment)? And as for the points i need to be joined i have to log the min succesion to be connected succesfully
Sorry for the nonsense but this is a new world to me. i understand nothing
Its like using one of those old crappy square 6volt flashlights from the 70s to using a rechargeable 1200lumen surefire.
This place teaches me stuff everyday.
I use B for begin line and E for end line.?ÿ I utilize the OH code to offset lines (usually curb and gutter or sidewalks) rect for closing a 4 sided figure.?ÿ Once you get used to using the coding, it will be second nature.?ÿ I use f2f for every job, no matter the size.?ÿ All curbs, EP/concrete, fences, decks, pools, retaining walls, top of bank / toe of slope, centerline ditch, etc. gets drawn in the field on the fly.
Here is a little part of an actual topo I did last month. My code for gutterline is "GL" and for top back of curb is "TBC". "EC" is edge of concrete. "B" begins a line and "E" ends one. "PC" and "PT" begin and end a curve.?ÿ
This is Civil3d, but at this level its all the same as Carlson. Raw codes are shown.?ÿ
I begin with the gutterline at the west end and run east, around the curb return, and north to the end. Then I begin the back of curb and run south, and then west to the end. At the driveway panel there is double coding to connect the edge of concrete to the curb. Also shown is a piece of Edge of Asphalt (EP) and the building face. For clarity I've omitted a lot of other stuff.
In this case I didn't jump back and forth between GL and TBC. I ran the whole line of one and then the other. I prefer a bit of walking over a lot of keyboarding.?ÿ
Hope this helps.
Similar approach:

@norman-oklahoma I prefer the cross section approach rather than walking the same lines back and forth. ?ÿNo extra keyboarding.
And there's minimal keyboarding required if you set up your DC with a grid of one-touch buttons to store points:
One of the most under-utilized functions in my opinion. 3-5 minutes of setup and I don't have to do anything but tap the appropriate button as I cross-section. Back of walk, top of curb, flowline, lane stripe, crown, stripe, flow, top, back....pace 25 feet down the corridor, repeat.
Tap + to advance to next linestring, if I need to replace a grid button, tap and hold, enter code, accept, go back to surveying.

Years ago I worked for a large company that had a President who would spout thinking outside the box, but never actually made it possible for us to do that because of his rigid thinking. In short, he repeated the latest buzz words but was otherwise clueless. Everything had to be done the traditional way with the traditional hierarchy.?ÿ
When I went out on my own I knew a path to success was high tech and a solo practice, and after 20 years I can confirm that was the best choice, using my own COGO and my own F2F optimized for maximum efficiency. I made money, a lot of money.
I happened to meet him in a local coffee shop and he asked if I was still surveying. I said I was, still working solo. His reply was, "Oh, well, the important thing is you are happy." Still rigidly clueless.
Bottom line: F2F properly used is maximum efficiency. Collect everything, dump it in the computer, and there is the drawing in seconds.
Time to sit out front with a glass of wine and watch the sunset.
The BEST option (IMHO) is not using "end"
If you simply start the line with a unique identifier each time, then there is no need for either.
?ÿ
EC1
EC2
EC3
And Carlson SurvCE (etc) will automatically use the next available identifier, if you set it to do so
Works with ACAD database import as well.
And if you aren't solo, it may be even more important. If the crew can draw the data on the screen and it makes sense, then the drafter (who has never seen the site) has a much better chance of actually making an accurate drawing.
For cross sections I label lines on my left odd numbers and lines on my right even numbers.
There are definitely more special codes that can be used.?ÿ I was just trying to give the OP the basics for getting going.?ÿ
Another good one is using PT for a curve more than 3 points.?ÿ
I find that closing figures and doing offsets in the office goes pretty quick, so I don't bother with a lot of those in the field.?ÿ And I'd rather take another shot than using the JPN to connect to a prior shot point.?ÿ
You just need to try it out, and find out what works for you.
I use sequences for repetitive pickup and you don't have to make any coding changes between shots and you can still shoot a pole or mh in the middle of it all. The only drawback is you need to have the exact number of shots on every section, one extra or too few and it'll mess them all up. So for example code X9 could be a rural road section (BS, DL SH EP CL EP1 SH1 DL1 BS1) . . all with one code.
Yes, but how many numbered strings do you need to use??ÿ
I mean, once you're done with a section of road, you can go back to using?ÿ
BS TS TC EP CL EP1 TC1 TS1 BS1
you can use those same codes again.?ÿ So you don't have to keep increasing numbers, unless you have more than 2 EP's in a cross section.?ÿ You only need to use numbers if you're collecting similar features at the same time.
If after doing a cross section of road you need to locate a parking lot, you can go back to using just EP for the code.?ÿ You don't have to be at EP21 or anything.

I find the JPN code very useful for shooting a guywire and having it connect it to the previous PP shot. This minimizes time in the office trying to figure out which PP the guy goes to if you have several in a small area.?ÿ
