hm_measureshortestdistance not working properly

I got the ans, elem is not a valid entity type for this type, the Valid values are nodes, points, lines, surfaces and solids.Apart from this is there any api which can do the task which I intend to do ?

How about this:

*createmark nodes 1 'by elem' 599

*createmark nodes 2 'by comp name' auto1

set N2 [lindex [hm_measureshortestdistance nodes 1 0 nodes 2 0 0] end-3]

*createmark elems 1 'by node' $N2

puts 'closest elems: [hm_getmark elems 1]'

You can use hm_entityinfo centroid elems

to get centroid of e599 and the closest elems then compare which one is closer to e599 => decide that is closest.

hello Tinh 

hm_measureshortestdistance nodes 1 0 nodes 2 0 0 is giving 'expected integer but got '0 ' error ..

maybe, you copy & paste my code. Be not lazy, pls type it again, man!

a relevant command you should refer:

hwat::utils::GetClosestElement

in package hwat

Refer HW Help Home> Hyperworks Tools > Hyperworks Automation Toolkit

Nopes I didn't copy pasted. I typed myself many times but everytime the same error its giving. 

hwat::utils::GetClosestElement first three arguments are x y z coordinates but the last argument is assembly name. This argument is not working if I give the collector name as here 'auto1'

put that collector (comp) in an assembly,  and use the assembly name as argument

yes putting that component in a different assembly works. Thanks for the solution . And I tried the hm_measureshortestdistance on a different computer but its giving the same error
