Label the midpoint of an alignment

[CharlieDFW]

I would like to label the midpoint of an alignment that has multiple segments. Anyone have ideas on this?

The simplest way is when making alignments in CIV3D do not answer Yes to delete pline. You can get the midpoint of a pline very easy its a point at 1/2 the length of the pline. two VL functions. You should be able to add that point then to the alignment. 

 

This is get a point at mid point of a pline.

 

(setq obj (vlax-ename->vla-object (car (entsel "\nPick pline "))))
(setq len (/ (vlax-get obj 'length) 2.0))
(setq pt (vlax-curve-getpointatdist obj len))
