Created Vector and Retrieving Coordinates of it.

Hello

There are 2 kinds of vector and your mention is about vector entity. to create it using *vectorcreate

and refer to data names of vector entity you can find its component (to use with hm_getentityvalue)

Hi tinh,

Thanks for replying /emoticons/default_smile.png' alt=':)' srcset='/emoticons/smile@2x.png 2x' width='20' height='20'>

i am trying to retrieve the coordinates through 'vector' as an entity.

firstly i had created the vector as an entity through 

Hello Shivanshu

did you read all data names of vector entity?

please confirm  is it exactly 'globalx' ? this is available for node entity but sometimes it differs from other entities

Shivanshu,

For vectors, you should use xcomp, ycomp and zcomp.

hi cesar & tinh,

i had tried to retrieved the coordinates of vector with:

set a [hm_getmark vectors [*createmarkpanel vectors 1 -1]]

then for 'X, Y, Z - Coordinate' 

set VX [hm_getentityvalue vectors $a 'xcomp' 0]

set VY [hm_getentityvalue vectors $a 'ycomp' 0]

set VZ [hm_getentityvalue vectors $a 'zcomp' 0]

but its not working.

BASICALLY I WANT TO RETRIEVE THE COORDINATED TO DEFINE THE DIRECTION FROM THIS VECTOR.

After the import has been completed, copy the following tcl code into a file in your desktop, name the file get.vectors.tcl

 *createmarkpanel vectors 1 'Select vectors';set vectorList [ hm_getmark vectors 1 ];foreach a $vectorList {	set VX [ hm_getentityvalue vectors $a 'xcomp' 0 ];	set VY [ hm_getentityvalue vectors $a 'ycomp' 0 ]; 	set VZ [ hm_getentityvalue vectors $a 'zcomp' 0 ];  puts '$VX $VY $VZ';}

In the command window type, source path/to/the/file/get.vectors.tcl and review the output.

Hello

to specify a direction from 2 nodes (or 3 nodes) you can retrieve node coordinates x, y, z and compute vector components by using hwat (or write it yourself)

This is an example

package require hwat

*createlistpanel nodes 1 'Select direction by node1->node2'

set nodelist [hm_getlist nodes 1]

set nodeid1 [lindex $nodelist 0]

set nodeid2 [lindex $nodelist 1]

set coord1 [expr [hm_nodevalue $nodeid1]]

set coord2 [expr [hm_nodevalue $nodeid2]]

set vectorcomps [::hwat::math::GetVector $coord1 $coord2];#or you take x,y,z in coord2 plus x,y,z in coord1

puts $vectorcomps

you don't need to make vector entity

thanks tinh & cesar.
