Slide vs (Dup loop and slide) ...

[Arg Arg]

Hello puzzledpaul & ggaliens,

if i understand right... the coding strategy is to combine internal functions?
if so, i found a workflow with a manifold-lab-function, while checking the advice of puzzledpaul.

Here is the workflow with manifold-lab:

- SELECT target-edge-loop
- EXTRUDE (MMB) [along selection normal] Distance=0.0 AND %=0.0
- DESELECT all
- SELECT edge ring next to the targed-edge-loop (the direction you want to slide the duplicate)
- switch selection to FACE-MODE
- now use the manifold-lab-selection-function in FACE-MODE:
SELECT>Lots More...>Left,Right,Top,Bottom,Etc. (to edges)
and choose on which direction your target-edge-loop would be selected
- Now, the target-edge-loop is selected, but it is the duplication of it
- SLIDE the duplicate edge (now, you can slide in the direction you have choosen by the edge-ring you have selected)
- switch to BODY-MODE
- Clean Up (there are still one duplication on the target-edge-loop)

...but it´s not really a big fun if it is not one command
EDIT: the manifold-lab-selection iam talking about is not working in all
situations... so, i take it as example perhaps if it could be improved for such tasks... just an idea

on my test, after extruding the edge (D=0.0, %=0.0) that is creating two
duplications of the edge, there are some different results if you re-select
the target edges and start to slide (no matter if closed or open edge-loop) here are the different results:
- sometimes it fails completly
- first you slide the first duplication to -x and after re-selecting the
target again the second duplication to +x
- first you slide the first duplication to +x and after re-selecting the
target again the second duplication to -x
- you slide the two duplications in the same time to the opposite
directions
EDIT: same results with CREASE (0.0, 0.0)... i can not see any difference
between the results CREASE (0.0, 0.0) and EXTRUDE [MMB] (along selection normal) (0.0, 0.0)
...just two duplicated verts and edges
