length of line - associate

[enescil]

Hi,

I am a begginer in VBA. 

I wrote a VBA that put text/field of lengths of lines and arcs (like in dwg attached). I need that these texts are associate with respective lines. For example, If I stretch lines, rotate lines, text must change position (middle of line) and slope.

I read something about reactor in Lisp, but I am not finding in VBA.

I have no knoledge in LISP.

I saw this lisp below and I think that is possible do it in VBA.

Anyone can suggest me parts of codes to study how to do this?

Sorry my English.

Hi,

I suggest you to use geometric constraints. In your case _GcCoincident and _GcParallel will do what you want. But this commands not accessible from vba, you must use "sendcommand" from vba to achive.
