multiple offset

I didn't get it, this is a response to alan or my post?

whichever it is it hits error: no function definition: VLAX-ENAME->VLA-OBJECT

I'm not much into Vlisp yet to debug it

Ooops sorry about that

You AND Alanjt

Add this line:

 
(defun c:IOI (/ AT:TriangleArea ss i ent obj dst off)
[color=blue][b](vl-load-com)[/b][/color]
[color=#0000ff]....[/color]

It can be done, BUT i will code it to work only with closed polylines. I believe you know what will happen if its not specially with a 2 vertices polyline.

 

 

 

Your orignal code shows exclusive selection for ""LWPOLYLINE" BUT we can manage that.

Hello pBe,

Could you modify this code so it allows selecting many object lines ,arcs splines and polyline and offseting them simultanously.

I believe something is wrong, it only offsets five time outside, I rather the #6 post yet

Just as I suspected. you have a "seemingly closed" pline

use this on your pline:

 (defun c:test ()
  (cdr (assoc 70 (entget (car (entsel)))))
 )

command: test

select objects:

the result will be one of these bit values

0

1

4

128

129

132

133

Like most of the codes on this thread, inifinite will only works with flg 1

But no worries, we can still accomodate your request by testing if first and lastpoint is equal

See updated code

Ok Anishtain4, its your call

I would suggest you use the code at post#19 where you can select multiple objects , if the its a 1 segment pline it will prompt you to pick the side then proceed on the next one. we can tweak it to prompt for number of repeat like the one on post #6 >

Cheers

It's #6, #9 closes the polyline which is not something I want, I don't use multilines because I have to adjust all of my drawings in regard to others, so I have to do them one by one. I just changed the ssget line to "_:L" so if I missed the first click I won't have to repeat the command from the first.

Thanks

FWIW #19 [updated code] doesnt close the polyline as long as first and end point is the same.

Anyhoo, you are Welcome anishtain4, at least you have a couple of codes to study [Alanjt/EP/Lee Mac/pBe/tharwat]

Have fun

In my experience it closes all of my polylines and then start to offsetting. Yeppppp, I have a lot of codes to study, and thank you all

Hello pBe,

Could you modify your code so it allows selecting many object lines ,arcs splines and polyline and offseting them simultanously.

Upgrade your IE to the latest version.

It can be done, BUT i will code it to work only with closed polylines. I believe you know what will happen if its not specially with a 2 vertices polyline.

Hi pBe,

Hope you remember me, this Lisp is working with Line only. I don't want that Infinite Mode, if I want to select any PLine (or both "Line" and "Pline") then how is this possible? Thanks.

Welcome to the forum Saqib_theleo,

Looks like you heed my advice and posted your request where you got the orignal code.

Now. what exactly do you need? What you're asking is not that difficult at all, only, there are a couple of codes (AlanjT/LM/Tharwat/.... ) posted on this thread, i suggest you try them all first and see what code is better suited for your needs (you know what they say about re-inventing the wheel) [bTW: who are these people they cal "THEY" ? is there a building out there with a room that says "THEY" on the door? ]

Or maybe, you need an entirely different routine.
