I am almost embarrassed to ask this as I have been using SP for 15 years but I have never needed to do site plans. Always left that to the surveyors.

But I need some help with creating a site plan using the coordinates the surveyor used but I cannot seem to get it to work the way it should.

The problem I have is basically not understanding how those coordinates work

I can make a simply site plan, (such as the instruction video supplied by SP) but thats it.

I would like to be as accurate as possible.

I have attached a sample of a lot (Lot: 77)  that I need to do a site plan for.

When I use the coordinates I cannot make to look like the sample.

Any help would be greatly appreciated.

Thanks

Jerry

Assuming that you've used the right co-ordinates, you probably ended up with a zig zag line, for want of a better term. All the lines are probably correctly oriented, but typically some are joined at the wrong end, so you may need to do a little juggling ... Move the lines ... OBVIOUSLY don't adjust them.

 

Can you post a picture of what you ended up with.

My problem is more likely that I do not understand these coordinate process!

In the attached picture when tried to enter the bottom coordinate 132 22 15 it changes it to  s-89-37-45.

Same with the one on the opposite side.

If its ok , can I sent you the SP file?

Thanks again

I've come across a couple of surveyor coordinate techniques, ..

(and I am NOT speaking from a great deal of experience or understanding here)

 

Out this way, angles on a given property are relative to each other, .. but I have seen some where all angles are given relative to North as 0°, ..

 

.. the later I've found confusing by virtue of the fact that I encounter them less frequently, ..

 

.. have you tried laying out your site with both approaches?


.. invariably, someone will have a simpler solution.

Sure. You can either add it in the forum or send it as a private message. If you're comfortable adding it to the forum (make it a zip file), that may be preferable, as others can see what they can do too).

 

Here all our surveyors co-ordinates are given as "Northings".

Here is the file.

It is just a site plan test file with no buildings.

Maybe if you can make it work i'll look at what you did and that might help this old brain. :)

Thanks guys for helping out.

Jerry, that drawing appears to be blank ... Even checking DISPLAY EVERYTHING in Visible items I don't see anything.

I don't think it's something that you are doing ...

 

The "Surveyors" drawing isn't in Surveyors co-ordinates as I understand them (and I suspect not as Softplan understands them either), and even drawing them as lines at angles, I'm getting everything going in "wrong" directions. I'm not sure how the angles have been derived. They are probably correct, but not in a format I'm used too.

I'm glad it not just me.

I attached the project this time.

When I input the degree, minutes and seconds from the surveyors drawing, Sp changes them after you hit enter.

I tried doing these site plans a couple years back but gave up.

Thanks again

Jerry

In system options check to see if north is set at 90 & indicate angle quadrants is checked.

They are in angles but not necessarily in bearings.  They need to be given a start point as in  N13.16.43 E or similar.  Otherwise you have to assume where the start point is.  You can probably get close based on what he has given you but when he uses "assumed" for a bearing that is like us using NTS (just a way to say "Not That Sure")

I tried to just draw them with lines at angles, but the 132° and 162° lines got closer together not further apart. I don't doubt they are 30° apart, but they are very awkward to draw with the way Softplan defaults.

Thats what I saw too.

Maybe there is some math involved.

I'll keep playing with it.

Thanks much

No disrespect but since I am not totally versed on the metric system is there a different way of doing bearings or coordinates that may not be in angles and degrees?  perhaps radians and gradients?  Just trying to think out of box.

None taken..... I'm not keen on it either :)

The measurements are in meters but the coordinates are in degrees, minutes and seconds.

I believe thats an international thing.

Maybe I'll have to send this off to tec support.

I've dealt with strange one before having to move lines and attach them with snap at different points but this one doesn't seem to make sense  :wacko:

I didn't test it but think maybe the n72 21'50"w  maybe should be n72 21"50" E or changed with the    N-S or E-W.

the N-S  and  E-W sets the lines in different directions

The info on your plat is missing all the n, s, e, w coordinates.  No clue how you could possibly recreate the plat without that info.

Okay ... For anyone who comes across this again ...

 

Go to - PROJECT OPTIONS - NORTH OPTIONS: Uncheck INDICATE ANGLE QUADRANTS and (in this case) Check MEASURE ANGLES CLOCKWISE. Using quadrants you can't enter past 90°

 

2016.10.19_21h05m48s_003_.png

 

I've rotated the site 17°39'50" to make the top boundary horizontal.

 

2016.10.19_21h38m38s_001_.png

 

It looks like the radius angle was calculated wrongly ... As you can see I took the angle from 90° and got something that looks right. Which makes a lot of sense if you compare it with the 72° boundary on the rear.

 

Jerry, I've enclosed the SPD file for you ... it doesn't close correctly, and a few of the dimensions are a little off, but compared to what you had it might be workable

 

I've learnt something this evening!
