Property lines via bearings

[Nicinus]

That approach only works if there is only one curve, and the chord is known, which I find it typically isn't. Have a look at my original post.

[Doug Park]

Of course. I just used what seemed like the easiest way based on the data given.

[sutcac]

I find it is very common to come across errors in survey information.

[Nicinus]

Well, knowing what I know now by learning from this thread I find Chief very flexible in handling all sorts of problems, but I would still like to cast my vote for a table based tool for those times it makes sense to just enter the data and be done with it.

[Rich Winsor]

Every once in awhile I like to try one of these just to see how easy it is:

This is what I got.

Something else I haven't seen before. How did you include the image in the body of your reply and not in an attached thumbnail? I really haven't explored the nuts and bolts of forum posts to any extent. Can anybody do this or do you have some kind of special administrative dispensation?

[Doug Park]

I used insert image and uploaded it from my computer. The interface is really clunky, but it gets the job done.

[lbuttery]

I started at the lower left and worked around clockwise.

Doug:

while doing this, make a mistake and then try to correct it

this seems to cause me issues...

I also vote for table entry

Sorry, the north property line has an angle of: S89 57 07 E

I often have a property on a curve that changes radius directions like on a cul-de-sac...one radius to start the cul-de-sac widening, and another to finish the circle...I have one I need to do soon...i can find the info and post it and see how to make that one work using input method.

[Ben Palmer]

OK, here is a typical cul-de-sac with (2) arcs ....i've included the curve table to eliminate human error....so two attachments...this is a much better example with more typical data that I see on plats:



Thanks again for everyone's help and input...been with Chief a long time and still struggle with the input of arcs on site plans...i resort to many of the methods described in previous posts...on the example above I will often use the center line of the cul-de-sac, draw circles, trim, etc. to get it accurate...i like to use Chiefs line labels...but if it isn't exact then I need to manually label them...that could be the surveyors fault. (sorry for punctuation errors...too lazy to correct)

[billemery]

If one assumes that the north, east, and west property lines are correct, then the data for the south property line is incorrect.

I have used the method I described earlier, with each line developed independently, and then snapped together using the point to point tool. I see this method as similar to the table input method in that each line or arc is developed independently.

In this case I snapped together the three straight lines, and then connected the remaining segment with a straight line, and converted it to an arc with the given radius. The data for this arc, and chord do not match the given information.

As a civil engineer and one-time sort-of surveyor, I am shocked, absolutely shocked, that survey data is sometimes wrong.

There are some excellent online calculators for validating curve data.

[Ben Palmer]

OK, here is another one...would love to see how everyone would do this...I can get it done, but takes some work...would be great if I can just input one line/arc at a time with information provided, and it drew it for me:



you can download the source pdf file here in case you want the big picture or if I didn't capture everything (lot 107): http://156.42.40.50/PlatPdf/801PLAT3307.pdf

I did a video on inputting bearing lines.... if you are a little weak in this area, this might be helpful.

The real lesson here is knowing the information you need to connect a curved property to a straight property line when the curve is not tangent to the straight. No great shakes.......

OK, so finally getting back to this:

Thanks for the video Scott...I think you demonstrated exactly my point...there isn't a methodical way to input the information and have chief draw it out for us...we have all the information provided to us by the surveyor, but yet we need to do some extra curricular methods to draw it up accurately...I do it a slightly different way than you, but that also shows we can do it...but would love to just enter the arc info in just as we do the line info, and be done...curious to see if thats how other softwares handle it....maybe that is norm??

Thanks again.
