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...

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.

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. 

Thank you Saxlle. It work awesome. much appreciated.
