A little more info. Looks like this problem comes from the
finish_copy call in GMT. If I comment the lines in blue, my new
functions for copying tag data from one entity to another work as
expected.<br>
<br>
My thought is to add a flags for these functions with regards to
copying entity tag data/ attribute info. In the GMT functions the
default will maintain the status quo (do not copy the attribute
data) whereas in the iGeom interface the default will be to copy the
tag/attribute data. Does this sound acceptable for now? As of yet
this is the only change I will need to make outside of the itaps dir
in CGM.<br>
<br>
Cheers, <br>

Just checked and this fails when built w/ CUBIT as well. <br>

Hi all, <br>
<br>
I just ran into an interesting problem in CGM built with OCC.
When an entity is copied, the original loses all user-applied
tag information (or so it seems). I understand why a copy might
not keep data from the original, but for the data to disappear
from the original altogether seems like incorrect behaviour to
me. <br>
<br>
<br>
I wrote a test as an example of this below. The test fails on
the red line. Any ideas as to why? I've tracked the number of
tags on the entity and they seem to disappear in line 5804 of
iGeom_CGMA.cc.<br>
<br>
Any help or insight for this would be very appreciated! I'm
close to finishing my updates to the iGeom interface and this
seems to be the last piece of the puzzle.<br>
<br>
<br>

<br>
int err;<br>
<br>
//create a tag<br>
iBase_TagHandle test_tag; <br>
std::string name("test_tag");<br>
iGeom_createTag(geom, &name[0], 1, iBase_INTEGER,
&test_tag, &err, name.length());<br>
