Beginning and ending of joints betwwen components

Alex.01

Hi all,

 

I am creating a new script which detects joints between several components and identifies the start node and the end node. I show an example in the image below:

 

 

I am able to detect all joints with the *findmark command, but I don't know how to identify the node which 'starts' or 'ends' the joint. The start/end nodes are those which have temp nodes in the image.

Can anyone help me to do this? Any suggestion?

 

Thanks in advance,

Alex

Hi Alex,

 

Find shared nodes using hm_getnodessharedbyothercomps in mark 1, find edges and get all edge nodes in mark 2.

Then get markintersection?!

Hi vipin,

 

I think that could work but I forget to say another restriction. I show it in the image below:

 

 

 

Is there any possibility to specify a 'break angle' which allows to put more temp nodes, like in the image?

Can you try with the features(command is *features_advanced) option in tools menu?

It will provide you with plot elements along the features based on break angle. Then you can try some logics with the plot elements.

Hi

If you don't find an 'hm_' command to get these vertices:

*features_advanced  (as vipin suggestion)

*createmark elems 1 'by comp name' ^feature

set NodeList [join [hm_getvalue elems mark=1 dataname=nodes]]

array set Count {}

set Vertices {}

foreach NodeId $NodeList {

   if {[incr Count($NodeId)]>2} {lappend Vertices $NodeId}

}

puts $Vertices

 

 

Before version 13 we don't have command 'hm_getvalue', so looping through each element by tcl and get its nodes is quite long. at that time, to query such data i had to use an hm template to fasten script.

I really thank you guys, you helped me a lot.
