How to change working directory

hi Karthi

use 'cd' command

cd 'C:/folder'

but you already use *jpegfilenamed so it's better to direct path in filename:

*jpegfilenamed 'C:/folder/$compname'

Thanks for the Reply!!!

I have to check if component is not there it has to come out of the program.. For that i used the following command.

if {$comp == ''} {
break
}

But it is showing a  HM error message as    ' invoked 'break' outside of a loop '

it should not tell any error message it should come out without it..

hi,

the error is invalid using of 'break'

you ough to use 'return'

Thanks for the Reply!!!

I need to use the translate option like moving the elements in mark 1 from N1 to N2

Ex:

*createmark elements 1 displayed

*createvector  1 0.7085 -1.6000 0.0001
*translatemark elements 1 1 0.2

Like this it is coming in CMF file. how do i get the vector for 2 nodes.

I also want to get the coordinates of a node. when i try the following option it is saying it can be used only for points.

hm_getcoordinates points 1

How do i create the points for the nodes in mark.

Thanks in Advance!!!

hi,

to get coordinates of a node you can use hm_nodevalue:

foreach {xcoord ycoord zcoord} [expr [hm_nodevalue $NodeId]] {}

and from coordinates of 2 nodes you can get a vector by (x2-x1) (y2-y1) (z2-z1) (or using utilitiy function in hwat - please look at help about hwat)

Thanks.. i got the coordinates.. but the problem is i need the X,Y,Z values in different variables ..

set cor [hm_nodevalue $nodeId]
set x [lindex $cor 0]
set y [lindex $cor 1]
set z [lindex $cor 2]

When i use this i m getting the whole X,Y,Z in Variable x itself. Help me on this!!!

Sorry i did't use the full line before... i got it thanks...
