hm_measureshortestdistance not working properly

All the brown color elems are 3d elements in the collector solidmap while the green color elems are 2d elems in collector auto1.

I execute the following command

*createmark elems 1 599

*createmark elems 2 'by comp name' auto1

hm_measureshortestdistance elems 1 0 elems 2 0 0

it returns-> 0 0 0 0 599 0 0 0 1 0 0 0

but as we can see the distance between elem id 599 and elem id 1 is not 0.and elem id 1 is not the nearest elem to 599 among all other elems of auto1.

Can somebody explain this ?

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 ..

tinh

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

tinh

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
