TCL Console Command for filtering through Metadata

Martina Blazheska

Hello, I am working in HyperMesh by importing geometry as Parts, all of which have metadata. The metadata is stored specifically in the Parts and not in the Components belonging to said parts. I need to be able to select and place under the user mark the Parts which have a certain value for a certain metadata name.

For example. if in the metadata I have several sets of data as such:

<metadata_name>: <metadata_value>

I need to be able to access all the parts which have XYZ as metadata_value.

So far, I have experimented with hm_getusermark, hm_getvalue and hm_getmetadata, but I can't seem to get these commands to do what I want. 

I feel like this is a pretty specific question that requires some level of familiarity with TCL Query Commands and I would be really happy to hear some opinions.

Hello Martina Blazheska,

 

you should be able to use hm_metadata for extracting information

I defined in HyperMesh two metadata: a string that I labeled "test" and a double that I labeled "value" 

Using the following commands, I get the information as a list of list:

 

*createmark surfs 1 2

hm_metadata findbymark surfs 1

--> {surfs 2 test string srfse} {surfs 2 value int 2}

 

Then you could use  foreach loop to store metadata information in a tcl array:

 

foreach md $metadata {

     set SurfMetadata([lindex $md 2].[lindex $md 1].value) [lindex $md 4]

}

parray SurfMetadata

-->

SurfMetadata(test.2) = srfse

SurfMetadata(test.5) = newstring

SurfMetadata(value.2) = 2

SurfMetadata(value.5) = 36

 

 

Unsing the array, you can then easily filter out the metadate:

- by surface:

foreach md [array name SurfMetadata *.5] { puts "$md [lindex $SurfMetadata($md)]" }

-->

value.5 36

test.5 newstring

 

- or for a given metadata

foreach md [array name SurfMetadata test.*] { puts "$md [lindex $SurfMetadata($md)]" }

--> 

test.2 srfse

test.5 newstring

 

Does that help?

 

Best Regards,

Michael
