Help distance and azimuth lisp

May 2, 2013

When you use this system of entering angles, you are very careful to always use two digits for both the minutes and seconds.

So 45d3'5" would become 45.0305

You may have something there eldon.

Thanks all of you guys,

I really appreciate every help and suggestions.

But I still couldn't get a result that I want to. Sorry for my poor english, I know is hard to understanding my request.

The code bellow is a great code, is not mine. But I'd like to make it better.

Let me explain my request.

When I invoke the code, specify the start point, set the distance, angles write the polylines and press ENTER or ESC to cancel or finish the routine. (like a PLINE command).

If anyone has a better idea or suggestion is very wellcome!

Thank in advance.

Hi MAdruga,

if I understand correctly, maybe something like this...

[i hope Rogerio can forgive me]

Henrique,

Can you make it in such a way you can type the angle values within a single prompt. [the way the OP wanted after Bigal suggested it]

command: AZ

Distance: 40

Azimuth: 12.5635

or

Distance: 40

Azimuth: 12.0506;

Your modification use the concatenated string to feed as value on pline command. Which you can easily work out using the single value as shown above. A decimal equivalent of the compass reading for input.

I have not yet wrapped my head on Bigals formula for decimal angle

A suggestion 123.45'57" enter as 123.4557
Fix 123.4557 = 123 degrees

rem = .4557 * 100 =45.57 fix again = 45 minutes

rem = .57 *100 = seconds

angle = deg+min/60+sec/3600

convert all to decimal angle and use in polar function for next point

Thank you for helping out Henrique.

Hi pBe,

My post was only to try to understand if this is the correct direction that Madruga want to the code...

If so, redesigning the code and incorporate Bigals suggestion, makes much more sense, to me, than ask to the user to provided values to the code as text strings...

Cheers

Henrique

pBe,

I had not read this part

"I have not yet wrapped my head on Bigals formula for decimal angle"

with the testing purpose...

(setq a (getreal "\nBearing in Deg Mins Sec [DD.MMSS] : "));; <- 47.5603
(setq d (fix a));; -> 47
(setq m (fix (* 100 (- a d))));; -> 56
(setq s (* 100 (- (* 100 (- a d)) m)));; -> 3
(setq dec_deg (+ d (/ m 60.0) (/ s 3600.0)));; -> 47.9342
 
;; or

(setq dec_deg (+ d (/ (+ m (/ s 60)) 60)));; -> 47.9342

;; reverse test

(setq d_m_s (angtos (angtof (rtos dec_deg 2 4) 0) 1 4));; -> "47d56'3\""

Cheers

Nice work Henrique

Does that mean it could be as simple as this

(defun C:AZ (/ point ds a d m s dec_deg)
 (setvar "cmdecho" 0)
   (if (setq POINT (getpoint "\nPick o ponto de início:"))
     (progn
   	(command "_Pline" point)
    (while (> (getvar "CMDACTIVE") 0)	
	(if (and (Setq ds (getdist (getvar 'Lastpoint) "\nEnter Distance: "))
	         (setq a (getreal "\nBearing in Deg Mins Sec [DD.MMSS] : ")))
              (progn	
	      (setq d (fix a))
	      (setq m (fix (* 100 (- a d))))
	      (setq s (* 100 (- (* 100 (- a d)) m)))
	      (setq dec_deg (+ d (/ m 60.0) (/ s 3600.0)))
            [color="#8b0000"] [b] (command (strcat "@" (rtos ds) "<" (angtos (angtof (rtos dec_deg 2 4) 0) 1 4)))[/b][/color]
              )
          	(command "")
          )
      )
       )
     )
     (princ)
   )

or using polar

(defun C:AZ2 (/ point ds a d m s dec_deg)
 (setvar "cmdecho" 0)
   (if (setq POINT (getpoint "\nPick o ponto de início:"))
     (progn
   	(command "_Pline" point)
    (while (> (getvar "CMDACTIVE") 0)	
	(if (and (Setq ds (getdist (getvar 'Lastpoint) "\nEnter Distance: "))
	         (setq a (getreal "\nBearing in Deg Mins Sec [DD.MMSS] : ")))
              (progn	
	      (setq d (fix a))
	      (setq m (fix (* 100 (- a d))))
	      (setq s (* 100 (- (* 100 (- a d)) m)))
	      (setq dec_deg (+ d (/ m 60.0) (/ s 3600.0)))
             [b][color="blue"] (command (setq point (polar point (* pi (/ dec_deg 180.0)) ds)))[/color][/b]
              )
          	(command "")
          )
      )
       )
     )
     (princ)
)

I think between Bigal and Hmsilva suggestions, the OP will be satisfied with the solution. but then again.. maybe not.

Just a one suggestion, azimuth has a different calcultation

for local settings,

see here for more (resolved by Stadler):

Not sure about if I'm right though...

May 6, 2013

pBe,

the first code works as it should, but there must be some pre configuration, all the variables that define the topography world...

(command "units" 2 2 2 4 270 Y "insunits" 0)

As BIGAL wrote:

"If doing change units in other routines as well set up a preloaded defun so 1 line in your code in Civil stuff used all the time."

The second code, will give error, because we have to fix the angles, depending on the quadrant in which they are, because autocad measures the angles in radians and the direction is anti clockwise, and we are drawing in clockwise direction, and angbase is not the same, so will be need a lot more code, to achieve the same result as the first code...

I hope that the OP will be satisfied with the first solution...

Cheers

Henrique

Many Thanks, guys!!!

Really good solution, I'm very pleased with the goals.

I'm really appreciate the help.

The code on post #31 by pBe.

It giving a strange solution. I've attached the dwg file to explain better my request.

Hi Madruga,

the az code works as it should, the problem is Object Snap, set "osmode" to 0...

Add "_non" in the command, before the direction/length call.

Now the code works like a charm!

Thank you all of you!!!

Thank you for the info Oleg, I'll have a look-see

...the first code works as it should, but there must be some pre configuration, all the variables that define the topography world...

Why oh why did i remove that line in the first place. good catch Henrique

...the problem is Object Snap, set "osmode" to 0...

Correct.

Add "_non" in the command, before the direction/length call.

Even better.

Thank you all of you!!!

We are glad to be of service. Now if you can just wire the money to account # 1945..... just kidding

Very funny pBe. If I had enough money, I would certainly pay back for the service.

But I'm poor guy.

I'm really satisfied with the code.

You are fantastic, guys!

God Bless you.

Don't worry about it. We're just teasing you is all.
