Draw lines using Degrees, Minutes, Seconds in the the a: box

Steve Jepson — Wed, 15 Mar 2006 23:46:42 GMT

Where can I find info on how to draw lines using 0, ' , " ?

I am manageing to get it done with a littel trial and error but I think there must be a better way. What words in the search engine would turn up some results on how to do this?

What is it you want to know exactly?

When inputting figures just leave a space between each. Eg. 20 42 18 is 20deg, 42min, 18sec.
If there's no minutes required just don't put a number eg. 20 42 is 20deg, 42min, 0sec

Is that what you're after?

Cheers

No. I know how to do that. The problem is I don't know how to get the line drawn in the relationship to north and south I need. I always have to fool around with it. Enter the deg. min. sec. and lenght, it draws the line but then i have to draw a line perpendicular and mirror it or someting to the it relative my plan. I do reset the origin but still it can be confusing.

Attached is an example. and the origianl info. I drew some lines north and south (virtical) and used the angle tool to verify that i have the angle correct. What i would like to know how to do is get these lines to come out the way I need them with out all the fooing around. Try one and see what you get. You should be able to draw each line from the end of the last one and so on around the property.

original info file was to big. I will have to reduce and post it agian. sorry.
try this.

draw a: 70 37 31 . Does it match the line on the original? For me it is the correct angle ( sort of ) but is not not rotated relative to how I need it.

The easiest way is to use the skewed grid.

Draw your first know line to the length you require.
Now activate the "Set skewed grid" button and pick the end of the first line where you want the angle to come from and then the other end of the first line (or anywhaer along it).
This will set the skewed grid angle to match this line and you can then measure any angle from this line as it will now be set to zero.
Do the next line of your boundary and then reset the skewed grid from the end of that line to continue on with the next line.
Change back to the square grid when you have finished.
You will nedd to work in a clockwise direction for this to work.

OK. But I am hoping there is still a better way than that.

I really liked the way you do it in SoftPlan. (10 years ago) AutoCAD does it better too. ArchiCAD needs to add the ability to include direction as well as deg. min. sec....N 70 37 31 E in stead of only 70 37 31.

I hope that is on a wish list somewhere.

Maybe I am missing something about your posts, but you can enter the cardinal directions as part of the surveyor's unit angles. The method I used with your example (original_lines_103.pdf) is:
1. Click to start the line
2. Hit "r" key (to input length of line) and type "122.8+"
3. Hit "a" key (to input angle) and type "n 70 37 31 e" (note spaces)
4. Hit "enter" key

North is set in the Sun Dialog Box. In your example is appears to be at 90 degrees (straight up on the page).

David just beat me to the Easy Answer, As I was setting to type this. Use Surveyor's Unit in Preferences and type with the N (or S) and E (or W) designations.

Thanks guys. That worked just fine. I had to adjust my North direction in the sun settings and set preferences to surveyor's units not just deg. min. and sec.

Maybe its the difference in terminology, maybe it's the noise of the painters scraping the paint of windows right beside my desk with a power sander:

If you set your custom angle mouse constraint to match your Northpoint, start your line, constrain mouse to North, type "r" and input distance, then "a" (for angle) and "70 30 31-" then ENTER (remembering the MINUS before hitting ENTER), angle will be 70deg30min31sec anti-clockwise from constrained North.

Sorry if I'm mis-interpreting, head is pounding.

Sorry I didn't look at the diagram properly.
Didn't notice the angles were all taken from North direction.

The method I described works for the true angle between the two boundary lines.

An even easier method now I think about it is to draw the first line at the correct length and the known angle.
Then start the second line, place the cursor back along the first then type "A", input the angle with a "-" (minus) after for anti-clockwise or "+" for clockwise rotation and then type "R" & length then "Enter".
You don't need to reset the skewed grid this way.

Again this is for an angle between the two boundaries but could be used in this case also.
Just use "Shift" to lock the cursor vertical (North/South) rather than on the previous line and then "A +/-".

PS - Nor did I see Stuart's last post - he beat me to this.
