Re: regarding to pistion bowl motion
 

colect the vertices of the bowl. Do the following
: make the bowl alone as type 1
: CSET NEWS TYPE 1 VSET NEWS CSET csys 1 *GET IC8 Y 954 VGEN 2 0 VSET,,,0.0,-1 * IC8,0.0 VGEN 2 0 VSET,,,0.0,YPST,0.0

P.s Here 954 is the vertex number on the top of the bowl. You can select the vertex number on the surface of the bowl

You add this four line command at the end of .cgrd file

...Hope this will work
