Topic: bALLOON ROUTINE

[TJAM51]

I have the following balloon routine and all works well except when you have to type in the text. I receive the following error message. I am using 2004 architectural desktop.



Enter text:  (at this point I entered the letter A. It did the same with the
                   nymber 1)
Command: A Unknown command "A".  Press F1 for help.

I would suspect that it is in conjuntion with the text command being used....but it looks ok though .... perhaps a setting with the particular text you are using? Some text style definitions if they are predefined, will cause the text command to utilize a different number of prompts. When this occurs the problem you mention crops its head up....

have you tried looking at the one here?

Keith has a much better routine, but the text height requires that you
test for zero size.
I added that but you will still have problems with the circle from time to time.

oh no.. another old embarrassing moment  

[daron]

Want a vba version of the same program, written by the same person?

[hendie]

:horror:



Daron, I don't think that ever got finished.. did it ?
Keith & I were talking about that one just the other day. You're right, the VBA version is much better, having more error control etc but as far as I can remember, the project got kind of halted due to other work

[daron]

Yeah. I'm not sure if it did get finished. At the same time, I've come to learn that different browsers in the same family are bothersome. My version of Mozilla 1.6 views everything as I wrote it, but firefox hides the submit button on the original screen to my page and doesn't give a scroll bar, as well it does the same in the content areas. I haven't had much time to play with it since moving. I'd like to get that going again sometime.

I tried the routine dimbal that is dialog driven. I am seeking a way to draw a simple balloon or even a hex that is based on the dimscale.

[hendie]

you mention you're using ADT 2004 ~ this was written way back in 2000 ~ for Acad 2000 ~ have the text prompts changed ?
(or perhaps your text style ~as Keith mentioned)

for a quick test, check your current text style and change the height to 0 then run the lisp again ~what happens ?

[TJAM51]

I may have not ben clear...sorry...I am using ADT2004.

I think if you make this mod it will work for you.

Code: [Select]

(setq dsc (getvar "dimscale"))
(setq cad_dim_asz (*(getvar "dimasz")dsc))   ;Arrow size (in drawing units)
(setq cad_dim_tsz (*(getvar "dimtxt")dsc))   ;Text size (in drawing units)

If you are using ADT, why not use the leader routines already there under the "documentation" content?
They work!

I am not sure of this. Does this offer balloons?


Thanks

Yes, balloons, squares, diamonds, hex, of just text, all with your choice of splined or straight leaders.
Check it out in the "Documentation" content under "leaders".
