Thanks Christian -

yes, this works for simple objects and for entire branches.


What Mihail and I are concerned, however, is how this code would work 
when the user has done a polygon, vertex, etc. selection - note that in 
the 'processing' part of this code (after we save the original object 
list and before we attempt the restore), we mess around with existing 
scene polymeshes (via the C++ CMeshBuilder API). The user might even 
have selected items within the meshes we're modifying as part of this 
processing.

P.S.: It also respects branch selections.

Hi Mihail,

Using the GetAsString and SetAsString is bad whenever you add, reparent or
delete objects - it tends to break because the selection is stored
according to the object names.
Here's how I usually do it (not sure if there is a better way), Python:

preselection = [s for s in Application.Selection]
# This list now includes all objects you had selected (the objects, not
just their names!)

# When you're done with the script, this brings back the original selection:
Application.Selection.Clear()
for obj in preselection:
   Application.Selection.Add(obj)

GetAsText, in scripting at least, does return the "B:" prefix.
But SetAsText ignores it.

OTOH, SelectObj takes it.

si = Application
sel = si.Selection
Application.SelectObj("XSI_Man", "BRANCH", "")
tmp = sel.GetAsText()
print tmp
# B:XSI_Man
sel.Clear()
si.SelectObj(s)
print sel.GetAsText()
# B:XSI_Man

Perhaps build your own GetAsString equivalent where you prefix "B:" 
before any FullName that is branch-selected?

 Hello, list!

I have a command that clears the selection as a side effect. I
want to memorize the selection before calling it, so I can restore
it later.

I tried to keep the string from the GetAsString() method and then
restore it via SetAsString(), but that didn't seem to work for
branch select.

Right now I'm using the GetArray() method and later on I'm adding
all the CRefs to the selection. This seems to keep the selection
for all cases that I've tried, but there's an annoying side
effect. Every time I have polygons selected, the selection filter
is changed.

Any thoughts?

Thanks
Mihail
