I'm using Carlson Software. The lsp is awesome but instead of offsetting it one at a time, I was wondering if we could highlight all the numbers (text with different numbers) to offset a single line to a different distance. I don't want to offset the text. I really apologize for confusing you.

Looking for LSP for offset polyline by selecting mtext with value . I have a polyline that I need to offset with different distance and it would be great if I can just select the text and it will offs

With mtext you can use a stripmtext that will remove the control stuff and you end up with a plain text, google Lee-mac stripmtext.

When you respond "did not work" it does not tell us anything, need to know did you get error messages or wrong objects drawn.    Please provide more details.

So take the zero line and offset it ?

 

Need a dwg before and  after, use Wblock to make a new dwg with only relevant objects.

Added to my "to do list". fairly simple just offset or copy a line based on the chainage, will add a Horizontal scale factor.

Yeah, this one did not work. I was just looking for a regular offset by highlighting a bunch of numbers to offset one polyline.

When you respond "did not work" it does not tell us anything, need to know did you get error messages or wrong objects drawn. 

 

Please provide more details.

I uppload the lsp and type "loff", and it just ask me to select an object to be frozen. I attached a "Recording 2" for you to see. it's not an offset. Or am I doing it wrong?

Bigal. I was wondering if you can create a lsp that will offset a line with just highlighting bunch of numbers instead of one at a time. I attached a video as a sample. Thank you in advance.

Not sure how but posted wrong version the repeat had 2 wrong values in it so code above is updated.

@Jojo According to your posted video ("Recording 2") and explanation in text, try this LISP and see if it works for your neededs.

 

***Did a little update in code (hope it can be helpful).

@Jojo According to your posted video ("Recording 2") and explanation in text, try this LISP and see if it works for your neededs.

 

***Did a little update in code (hope it can be helpful).

@Jojo

The problem is that you type a "r" to offset. You need to enter "+" or "-", or just pick a desire direction to offset line or polyline from command line (you will see a highlighted values "+" or "-"). 

 

Best regards.

Also I've made few changes to original code... (added - (initget) before (getstring) which is changed to (getkword)) and (atof (strcat dir (cdr (assoc 1 data))))

Not tested though...
