API to find elements connected to node in Hyperview

There are a couple commands that will do this.

First *findmark:

hm_createmark can also do this by using the "by node" option. Something like this:

*createmarkpanel nodes 1 (user selects node or some other method of picking node)

hm_createmark elems 1 "by node" [hm_getmark nodes 1]

set elemList [hm_getmark elems 1]

Hello,Jouher

Good evening

I think the following few lines of commands can help you.

set node_set [mdl_handle AddSelectionSet node]
mdl_handle GetSelectionSetHandle node_select_handle $node_set
node_select_handle Add "id $nodeid"
set elems_set [mdl_handle AddSelectionSet element]
mdl_handle GetSelectionSetHandle elems_select_handle $elems_set
elems_select_handle Add "selectionset == [node_select_handle GetID]"

Just for your reference
