make objects as block

hi,all

when I draw a arrow ,line and text ,then I want to make them become a block

and I want to add the following attribute to the block.as the picture describe.

any clues to do this? thanks.

the attribute are:

1.when I move the text ,the underline will move.

2.when I edit the text, the length of underline can changed according the length of text.

3.as the same of 1 ,when I move the underline , the text can move to .

actually it is something similar to mleader in autocad.

Why not just use an MLeader (maybe with a block as the annotation), or am I missing something?

mleader is a choice.but it is subjected to the style of mleader???

in mechanic drawing,there are many situation which to make a dimension for “angle of chamfer”.

if I want to use mleader with a lisp command ,what should I do?

e.g.

(command "_.mleader" ...;what is the following?

I know the following codes can be used to build block and insert block.but how to add "move" point to the block and make the text in block can be edited?

(entmake (list 
           (cons '0 "BLOCK") 
           (cons '2 "*U") 
           (cons '70 1) 
           (cons '10 ip)
         ))
         (setq th (setq tmp le))
         (while (setq tmp (entnext tmp))
           (entmake (entget tmp))
         ) 
         (setq tmp (entmake (list (cons '0 "ENDBLK"))))
         (while (setq th (entnext th))
           (entdel th)
         ) 
         (entdel le)
         (setq le nil)
         (entmake (list 
           (cons '0 "INSERT") 
           (cons '2 tmp) 
           (cons '10 ip)
         ))

You could use QLeader and attach to a block.

sorry,not quite catch your idea.

can you show me some codes?thanks.

I noticed that you have written a amazing lisp here.

can you improve this lisp to make the whole thing (lines circle text) as block .and can be edited.I mean ,when I move lines

the circle(text) can be moved together.and I change the size the text ,the circle beyond the text can auto enlarge???

Thanks BlueShake - but that's an old program with pretty bad code - I updated it a bit here.

But really, for what you want to achieve, you would be better using a Dynamic Block. In fact, I believe there are already preset Dynamic Blocks available through the default Tool Palettes which will do exactly what you want - look under the Anotation Tab.

@Lee

for two reasons.

one is I want to know how cad(or you cad lisp master) do this magic.and the second is as followed picture.

the gap between text and line can not be set for Chinese words.it is annoying . I have read many post.and

can not figure out how to change this.

the gap between text and line can not be set for Chinese words.it is annoying .

For russian text too.

To raise the shelf above the text using the formatting \\pxse

Manually do this for a long time, so they beat written by several command. Maybe this would really work for Chinese.

MTLS - changes the line spacing. mode "a few" (format \\pxsm)

MTLE - changes the line spacing. mode is "exactly" (format \\pxse)

VLR_MTLE_ON - start (activate) reactor multilider

VLR_MTLE_OFF - stop (deactivate) a reactor

Sign of activity of the reactor - a line * LE * in modemacro (if anyone is not clear - on the left bottom of the screen)

Try to use MTLE, VLR_MTLE_ON, VLR_MTLE_OFF command

hi,VVA

first thank you for your codes.

I using your codes,and find the following problem.

I use mtle command and enter value "1", and it show left result in the picture.

but enter value "2" , and it show right result(which is wrong) in the picture.Do I miss something?? see the attached picture for more details.

but enter value "2"

Need to use the value in the 0.8 - 0.9. Try to specify a value of 0.86.

How to find the desired value formatting \ \ pxse?

1. Draw mleader with text height = 1

2. Use Line Spacing formatting

3. Find the value of paragraph line spacing. It will be

4. For mleader with a few lines I use paragraph spacing to omit 2 and subsequent lines

Use MTLE command for existing mleader

Before drawing new mleader type the command VLR_MTLE_ON

request to the moderators move posts, starting with 11 in a new thread

it work.cool.thanks.

@VVX

I add the following codes in the last line of your codes.but cad give error with no such command.

(command "VLR_MTLE_ON")

You cannot call LISP functions like that, rather:

(c:VLR_MTLE_ON)

:)cool man.Lee.
