How to create a node in the center by selecting one circular curve?

Altair Forum User

Hi all,

In hypermesh, we can create a node in the center by selecting three node on a circular curve. How can we script this?

Hi tinh,

I know your meaning. When using GUI, the center node can be created by selecting three nodes. How can we create the center node directly by only selecting one circular line not three nodes by using script?

Hi Roy,

 

You may already know this panel

use it generate nodes on the curve and use generated nodes to create center nodes. do necessary steps then you could find out commands in command.tcl

#
# to loop trough many crucial lines at one selection :

*createmarkpanel lines 1 'Select all lines to put temp-node at center';
set line_sh [ hm_getmark lines 1 ];
set ile_li [ llength $line_sh ]

if { ! [ Null line_list ] } {
  for {set i 0} {$i <$ile_li} {incr i} {
    set liID [ lindex $line_sh $i ] ;
    eval *createmark lines 1 $liID
    *createbestcirclecenternode lines 1 0 1 0;
    *clearmark lines 1
