Helloooo guys cad-world. I like the lisp LAYTEXT. Is it possible to put more than one text? If a line has a distance X, 2 are inserted or more texts. Is it possible?   Thank

Lee, thank you so much it works great. :D

I have a question is it possible to setup to select more than one line at a time, so i could label all at once?

Thank you again

Thanks Sherry,

 

Multiple selection is not possible with the current placement method, as each text is aligned to each object, and so multiple text cannot be aligned simultaneously (without tons more code).

 

If you wanted the text to be in a set position every time, then multiple selection can be achieved with relatively less code.

Hi Lee

If you don't mind revising the one for less code so it is in a set position, I would greatly appreciate it.

Thank you Sherry

It would have to be a new program, but I don't mind if I have the time.

 

Where would the fixed position be? The midpoint of the line?

The midpoint would be good.

I will use both programs just for different applications. Thank you so much for taking the time to do all this.

Could anyone else test the posted code to see if it errors? :wink:

 

Other than the text being tiny (Annotative), it works fine for me.

I just used TEXTSIZE variable, but gave the option at the top of the code... but glad it doesn't error :)
