      hey TIG
      here's a problem i've run into sometimes in an instance where it seems it should work. i'm only getting partial results in this case.
      any ideas?


      railQ.skp

        I have black crosses in the v7 ๐Ÿ˜ฎ
        and a false surface in the V6 ๐Ÿ˜‰

          using that same file, here's another weird thing i can't figure out. (a video's probably easiest for me because i don't have to type as much ๐Ÿ˜„)

          (at first, it shows the problem i was previously talking about)
          after that, i copy/move the profile and each rail the same amount along the red axis.. then end up with entirely different results.
          ?

            here's another question/problem i'm seeing..

            it seems like the grid should line up according to the corresponding segments of the two rails (the 2rails being at the top&bottom of this picture)
            .
            click pic for larger

            like this, there's a kink being created in the surface along the left edge (which is somewhat visible in the inset picture..the surface drops down prior to rising because it appears the grid line is in the wrong place).. i guess i could make the surface bigger than needed and trim away some of the outer edges but that's not really optimal.. if it's fixable, i think it's worth fixing.

            thanks a ton for figuring all this stuff out โ— ๐Ÿ˜„

              These problems seem to relate to the way the vertices in the the curves are ordered. They are reordered by the script before making the mesh... BUT obviously not well enough in some cases.

              If you explode the three curves in your railQ.skp in turn and then immediately weld them back into new curves they make the mesh perfectly... So my re-order and weld's must vary somewhere...

              I'll look at the ordering algorithms etc and release an update asap... ๐Ÿ˜’

                Amazing TIG!!!
                Thanky you!!!

                How about an option to maintain height?
                In your script shape curves scale in both the height and width dimensions. It will be great to have an option to remove the association between the height scaling from the width scaling for some models.

                As an example: here is what your script make:
                2.gif

                And here with Maintain height:
                1.gif

                  didn't even realize vertices were in a particular order ๐Ÿ˜„ .. is the grid example something to do with the order as well or something different?

                  daniel, that's going into a different territory in that the profile changes as it moves along the rails (the halfcircle doesn't remain the same in terms of shape).. if something like that is possible in SU then i have another request that's similar though different.. i'll hold off on asking for now ๐Ÿ˜„

                      When you want draw a "straight" curve line with some number of segments for fit with other curves for The TIG Plug
                      Draw a line, Right Click Divide then Weld = some painful ๐Ÿ˜ฎ

                      A more quicky trick ๐Ÿ’ญ
                      Draw a polyline of 1 segment by the BezierSpline of Fredo6
                      Then Right Click / Convert to Segmentor and enter the number of segments ๐Ÿ˜‰
                      Et voilร  ๐Ÿ’š

                      It's a pity than we can't draw an arc circle "Straight" or scale it to 0 or Bulge =0 ! ๐Ÿ˜ก

                          great plug thanks!
                          maybe you could combine this with edges by edges then have the option to pick just 1 rail or 2? one more function, one less plugin! ๐Ÿ˜„

                            Jeff, i found that if you explode the rails then weld them again that the problem is fixed. at least for me.

                              This is the temporary fix... I'm incorporating this into the code so the glitches don't happen... However that makes new glitches which I'm now fixing............. ๐Ÿค“

                                  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... ๐Ÿ’ญ

                                    TIG, probably a silly question, but what is the difference from this plugin and extrudebyedges?
                                    http://forums.sketchucation.com/viewtopic.php?f=180&t=20065&st=0&sk=t&sd=a&hilit=extrude+edges

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

                                          @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

                                          I take the slow, deliberate approach in my aimless wandering.
