Thinking of the easy way, I would offset the pline to both sides. Then step back through the vertex list &
adjust the vertex location to match 1/2 the width for that vertex & set the width to zero.
This doesn't exactly match the pline arc taper though. That would take two arc's I think.

Other method would be to create a new pline for each side using the vlax-curve-getFirstDeriv to create
a new vertex location.

Thanks LE,I want to get the BOUNDARY to finish other things,but not print. thanks again..

Thanks CAB,I only can think of the "offset" method. but finally find it can't achieve result nicety.
Okay,thanks again,I will try your method.or I guess there are other way interesting..

Another possible method is wmfout/wmfin. But the result is a mess of triangles given the example.

Once, from there, draw a rectangle surrounding the objects and use bpoly and create an external boundary....

Hola Luis,

What program do you use to create the animation?

Camtasia Studio (http://www.techsmith.com/camtasia.asp).

Excuse me!
How wmfin the same scale and position after wmfout?
Could it be expressed by lisp? thank you!!!
I have searched, but no result!!!

Top left hand coordinate of the same viewport you wmfout from, inserted at a 2:1 scale. You mustn't change the zoom factor or view center between the wmfout and wmfin activities or else the result will be wack. You can be more precise by examining the viewport coordinates and comparing them to the wmfin block bounding box, but you will find the ration is pretty close to 2:1. Finally, set all your display vars to the maximum before the wmfout -- the quality of the export / import is directly related. Search this website for a proggy called hires, it will do most of the latter for you. Having said all this, wmfout / in usually produces a mess.
