Select Perimeter Edges only
-
Yes, but that only works so smoothly when you can smooth your entire object like you did. Imagine an object where you have certain things smoothed for a reason, and other edges left hard. Then that way doesn't quite work. (though quite frankly that rarely/never happens in my workflow, and I also preyy much don't ever need to select all the outer edges, so the ruby script is not one I find useful). But it only took about 5 minutes to write, and much of that was copying and adjusting the menu system and the legal mumbo jumbo.
Anyhow, I'll post a working version in a minute John.

Pete's way can work with specifically unsoftened areas too; just do it inside the group, and when the edges are selected, hit undo

+1 for BTM
but I still posted the little ruby here:

Thanks, Chris!
When the script is needed (although it may not be often) it will be greatly appreciated ... usually after doing deformations + plus mulitiple intersections, odd shapes, etc., which seems like its always at the end of the day, near a deadline, and you don't time and are impatient
)It worked pretty well on this one (which is a result of a projection) but not quite. Anyway it will work I think for a majority of cases
. Thanks again for sharing.John
P.S. At least keep it alive in your archives.

Wow John, how can you work like that? Where's your axis? That model was very weird to try and orient with the axis off and no prior knowledge of what should be up or down.
anyhow, I turned on the axis and I was able to figure it out
As for the script not working right, that is actually because the model is a little off. Its not perfectly flat.
EDIT: Not that a model has to be flat for my plugin to work. But in this case, there are overlaps that apear to be flat, which are not flat. So the plugin selects edges that don't look like outer edges, but in fact are since they are not flat with the faces that are overlapping them.

Seems that is a 2D view of a 3D work

Chris, I only turned of the axis so they wouldn't show when I exported a jpg

this starts to suggest selection of loops, maybe creation of loops, maybe loop subdivide on volumetric models, not just planar objects.
never mind-- just a tangential rambling -

Well, here's his selection tools plugin:
http://forums.sketchucation.com/viewtopic.php?f=180&t=14975&p=114380&hilit=%5BPlugin%5D#p114380
It does have select loop. Its not something I've gotten the hang of in other modelers, so I'd have a hard time implementing it. But check out Thom's, looks like it should work for loops!

I don't think he has loop selection of edges--only faces at this time. I might be wrong. He may have updated it. What I am suggesting is already a native tool in Blender and a few other solid modelers.
Selecting a loop of edges could become problematic unless you had options to select at the bifurcations of a heavy triangulated model. Of course, Zorro would make short work of it unless that would be too heavy handed--in some cases a dispassionate slasher.

Edge Loop, could anyone post a screenshot of what that means? A "Loop" can be interpreted as many things.
-
Here you go.

The thing about these kind of selections, how do you expect them to work on irregular shaped objects? How do they work in other applications?
If it assumes that the shape is made out of triangles or quads things are very easy.

See TopMod

Have cool loops selection
And it's a crazzy prog
(here old version)

Yes, Remus and Pilou:
That is what would be called edge loop selection.
Now, what if the volume were made up of only triangle faces? or a combination of both quads and triangles(either hard or soft edges)
You would want to select the shortest edge loop around the volume, or the longest loop around the volume, or some specific path. You could then duplicate the path in order to subdivide, or do a follow me with an added figure, or an array copy--or whatever. -
Here is a good explanation of edge loop.
http://wiki.cgsociety.org/index.php/Edge_Loop
Edge loop terminates if there 3 or 5 (or more junctions), so for a mesh build with only triangle faces there is no edge loop. -
Thanks. That helps alot. Such a function is easy to add.
@unknownuser said:
In a stricter sense an edge loop is defined as set of edges where the loop follows the middle edge in every 'four way junction'
I'll add that shortly to my Selection Toys plugin.

Only thing is, from the screenshot in that article, I don't think the quad faces are planar. So in SU there'd be a hidden/soft edge across. I could make the script ignore hidden/soft edges, as an option perhaps.

That's possible. So option to ignore soft/hidden faces would good.
