dimension the outside only..

[gadgetjay]

Hi all,

 

 

I have to dimension hundreds of stands (drawn as a closed polylines) on a floor plan.

I have found lisps that dimension all side of the 'stands' the problem is I don't need the internal dimensions so currently I am using 4 lisps.. select all left hand stands lisp adds left dims, bottom stands lisp adds bottom dim ETC.

 

 

 

 

Can any one help stop me going grey by writing a code that only dimensions the outside and doesn't dimension the internal ones (where the polylines overlap).

I think the attached pic describes it better.

fingers crossed!

Getting all points then remove internal points.

 

 

Then need a clock sort routine so points are in a list. Then do dim pt1 pt2 etc.

if floor plan is squared convex hull IMO is doable.

 

my suggestion (if squared plan) boundingbox offset inner say 1% ssget crossing erase internal dimensions easier?

[BIGAL]

hanhphuc good idea. Hit it with a hammer rather than spend hours trying to work it out. Now for some time.

Hi, sorry been dimensioning more stands!

I wish the venue was square - no such luck.

I've attached a drawing of just the stand outlines so you can see my pain..

Here is a good start based off your example drawing.

Ronjonp great job picked 565 and did in one go, probably best to pick small amounts at a time.

 

One suggestion for gadgetjay is use UCS OB plan pick objects on angle this makes square picking so much easier. Then UCS W Plan to go back.

Ronjonp posted earlier but "500 errors " great job picked 565 and did in one go, probably best to pick small amounts at a time.

It was a quick example. Do you have anything to contribute with less than"500 errors" ? If you really look at the op example drawing it's less than ideal for an all in one solution.

Thanks for this Ronjon - seems to be doing what i ask for...

i'm unsure what the 500 errors are i just hope its not wrong dimensions!

[BIGAL]

Sorry guys the website kept giving me and others "Error 500" has occured.

[gadgetjay]

ok so if i change

(cons 1 (rtos (/ (last pt) 1000.) 2 2))

 

i get the decimal places which corrects the errors in dimensions (phew)

 

is there a way to make the text offest 500 from the stand? - i tried justify text and 50% are inside 50% outside

indeed a good start!

IMO the idea / algorithm is worth more than coding.

simple, short & faster than region boolean acUnion which need rounding tolerance

hi to be outside 100% the best solution is to involve or to learn coding !

added new argument CW

[gadgetjay]

Hi hanhphuc,

 

 

Trying to learn the coding but something like this is beyond my reach - it helps when there are notes in the code so you know what's happening.

 

 

 

 

wasn't sure if you meant to place your code in Ronjonp's as a 'standalone' it errors malformed list?

Good to hear you are learning

you are right this is not simple.

you can't simply add in the code, causing malformed list - missing parentheses or bracket ( ) or extra bracket ! to debug , command VLIDE or VLISP to open the editor

 

a sub-function needs to supply arguments.

i modified previous post#13 outline_TX function with additional argument cw. please re-copy

you try to draw 2 rectangles ccw & cw to test..

linear units precision 2,similar (rtos x 2 2)

nothing to do with placement

 

To suit your drawing, try to modify/add in the code post#13 (in red)

  

(defun [color="blue"]OUTLINE_TX[/color] (p1 p2 h cw  / pl d ro)
 (setq pl (mapcar '(lambda(x) (list (car x) (cadr x))) (list p1 p2)))
 (mapcar '(lambda(a b) (set a (apply b pl))) '(ro d) '(angle distance))
 [color="red"](setq d (* d 0.001))[/color]
 (entmakex 
.....
  	..... 

 

sorry about the 500 internal server error very painful to reply post

 

iMO it's diffucult for you as newbie,

nvm i try my best to assist, example in Ronjop's code just replace this part

 (setq pp (polar (car pt) (- (cadddr pt) (/ pi 2.)) th))
 (entmakex (list '(0 . "TEXT")
		 '(100 . "AcDbEntity")
		 '(8 . "BoothOutlineLength")
		 '(100 . "AcDbText")
		 (cons 10 pp)
		 (cons 40 th)
		 '(62 . 1)
		 (cons 1 (rtos (/ (last pt) 1000.) 2 0))
		 (cons 50 (lm:makereadable (cadddr pt)))
		 '(72 . 1)
		 (cons 11 pp)
		 '(100 . "AcDbText")
		 '(73 . 2)
	   )
 )

 

to this.

It's simple right? ( OUTLINE_TX FromStartPoint ToEndPoint Text_Height ClockWise_Predicate )

; with 4 arguments. in blue is the function symbol & in deep purple is argument

as you can see i also used Lee Mac's function LM:ListClockwise-p

[ronjonp]

Ah Man - it was wrong dims...

 

Really? With the example drawing you gave it appeared to be working correctly. Be aware that this code only looks at straight edges. If you have an edge with a bulge, it will return an incorrect length.

it was a decimal error as some of the stands had .5s - no biggy!
