        Your idea of being able to pick a profile and then pick just one rail is quite simple to do.
        For the next update I will add that option - you'll simply pick the profile and click on rail twice - if you pick another rail it works as now, if you pick the same rail again then it's assumed that it has a 'twin' at the other end of the profile and uses that... simplicity... 💭

          TIG, probably a silly question, but what is the difference from this plugin and extrudebyedges?

          Is is simple that this script allows for more random meshes?

            BTW, your plug is turning me into some kind of artsy fartsy... STOP IT! 😆

                @xrok1:
                for your excellent bowl and spork and "foon" model, did you use specific dimensions and scale? Or was this a free form experiment and the model elements proportioned by eye?
                I am preparing to use Extrude by Rails with dimensional or scale control and was wondering about this.
                Thanks, mitcorb

                  it was freeform 😆 but i can't see any reason it couldn't be dimensioned accurately if you wish to.

                      ExtrudeEdgesByEdges takes two groups - edges in them need not be continuous - and makes a mesh - it extrudes each edge in one set in the direction of the edges in the other - there is no 'followme' etc...
                      ExtrudeEdgesByRails is similar BUT it only works on curves. It takes a selected profile and makes a mesh from it along two selected rails [or with the forthcoming version one rail picked twice - making it similar in that usage to EEbyEdges]. The main difference is that at each pair of 'nodes' [vertices] in the two rails the profile is placed and rotated and then scaled to fit between the rails, giving a smoothly curving mesh surface: also the number of 'nodes' in each rail is equalized if the number of vertices in the two rails is uneven - now making the 'lofting' of two unequally segmented rails possible...

                        What are the possibilities of being able to orbit and inspect the initial results of the extrusion on rails while going through the checklist so that decisions can be made in the workflow? Does this make sense?

                          It's something that's not so easy to do... but I'll look at it - I currently have a version with most of the bugs ironed out - it'll be published soonest...

                              Very nice Tig.

                              Works great in SU7. However, doesn't work SU6, at least for me.

                                Here is v1.1 http://forums.sketchucation.com/viewtopic.php?p=201286#p201286

                                It is now much more stable, with [most] glitches fixed with ordered points and bugsplats.
                                You can now also double-click on one rail and used it as both rails.
                                Rails that start / end at a common vertex are now allowed.
                                Mismatched segment numbers in the two rails are well accommodated - as are looped profiles and rails.
                                Debabelizer language translation are now added to menus and dialogs etc, with ExtrudeEdgesbyRailsEN-US.lingvo and ES/FR versions in the TIGtools folder.

                                Feedback please...

                                    just out of curiosity, i drew the same shapes using the same dimensions in SU with EdgesByRails then i did another in Rhino using Sweep 2rails.. i then brought the SU surface/mesh into rhino and overlayed the two.. here's what it looks like.

                                    (Sketchup = red... rhino =blue)

                                    click pic for larger

                                    the render mesh in rhino was set at a density of 100 making it about as close to the true nurbs surface that you can view on a computer.. all the vertices from SU edges by rails are right there where i'd hope they'd be.

                                    so yeah, use this plugin with confidence 😄

                                        just in case that picture is confusing, here are the two surfaces separately..

                                        (rhino- blue... SU- red)
                                        click pic for bigger

                                        (sorry about the nasty quality of the pictures.. had to use screenshots because the output options in Rhino OS X (beta) aren't fully implemented yet.. i don't think my screenshots like red too much)

                                        ... and a render of the SU version after some joint_push_pull..

                                          red is edges by rails result, blue is edges by edges result?? i think blue wins my vote on how things should work.

                                            as far as i can tell, both methods give the exact same results (3 tests and while one of the surfaces ended up in a strange location, it still matched the other)

                                            if you're talking about the triangulation then:

                                            with edgesBYedges, one of the options after running the script is 'triangulate faces?'

                                            with edgesBYrails, the second option that pops up is 'erase coplaner edges?'.. choose yes and the triangulation lines will go away (as long as they aren't necessary for the surfacing but since the geometry is the same with the two scripts for 1rail1edge, they'll end up identical if you choose yes to erase the coplanar edges)

                                            that said, maybe there's something i haven't tried that will make the two 1edge1rail methods produce different results..
