[Plugin] Extrude Edges by Rails

does not get the results I wanted
hi you posted while I was uploading, so I'll add my 2 pennies, adding surfaces to the rails holds everything in place better for some reason and even adding these surfaces after exploding the group altered the finished surface in some cases, but not all.
Hi Tig,
I've been busy with your script trying to see what it can do and how it works.
in the process I've made every permutation of rail choice order and discovered a few things that might make the learning cur(v/s)e easier for some of us mere mortals.
To show things like the difference of going end to end or top to bottom, etc I used a horizontal reference grid on my last 'Jeffs Ramp' effort and made a new vert as well. these don't represent an ideal outcome or anything, but are simply static reference made using different tools so that none of the new ones match perfectly.
I then put all new mesh's on there own layer with a code so I could keep track and then made 30-40 different versions, which I compared to each other using scene tabs. After weaning out mostly identical ones, I'm left with 8 possible reliable outcomes.
So, I decided to tidy it up a bit a post it here for yourself and the curious.
the code for the layer name is- L = Long Arc end; S = Short Arc end ; B = Bottom profile; T = Top profile; rest are bad English
camera's not locked so you can rotate etc during the animation, if you stop and over lap two or more you can clearly see what's different
Comment... I think the differences are a bonus for things like ramps because it's so easy to just run an extra from top to bottom if you want it steeper etc...
BTW. I retrospectively added surface to my earlier post's drawing and it pulled the lifted edges back into place except for one point, the missing triangle on this file.
This one point also misaligned itself in a couple of other sweeps that had profiles attached, but not in others, odd?,
if the cleanup is pushing one point back into line , I'm happy...the files to big so it's on a cloud if you want to download from there, let me know if there's a problem.

Here's an EEbyRails new V2 example of making a 'flat-topped' sinuous roof barrel, with one end arched and the other angular, in two halves...[attachment=2:3i3yr7t7]<!-- ia2 -->EEbyRailsV2_FlatTop.png<!-- ia2 -->[/attachment:3i3yr7t7]
HI,TIG,This is way more than an improvement ,But it does not get the results I wanted, it seems that these two Profiles control only two rails of the endpoint, I want the result is the same curvature and hope to improve it, above are my small suggesting on V2 versions thanks again
It is doing what you tell it.
Picking the Profile twice will give a different result.
Try making half rails (~semicircle) and two concave profiles at its ends, then copy/mirror the mesh and combine into one group...
It the rail is circular use my Lathe.rb tool on its center with a profile on the circumference and at 360 degree revolution. -

Thanks for all of the permutation testing...
I'm unclear about this one missing small triangle - did EEbyR miss it out or did you ?
-
Seriously sketchstatic script... I can't imagine what's the next step for this!

Thanks for all of the permutation testing...My pleasure, I know there's a few people needing very accurate meshes for different things and quantifying what affects the outcome adds POL to your excellent script. {Principle of Least Surprise~ to quote Kirril}.
My contribution is minor compared to the effort you put in, and I don't write scripts (yet) so the least I can do is pass on some learning (and point out my errors).

I deleted the the inner edge of the wayward point (instead of fixing it) to keep tabs on when it did and didn't appear during my testing, and then decided it was tidier to leave it exposed then to fix and label it, I don't need to use the drawing.
why it's happened? I initially used 'paste in place' to add the top line sans surface for the top rail, later on I used 'paste in place' for the whole profile, to use it as the top rail. I was using group layers to keep everything separate, but when I did my final cleanup I had two identical ungrouped but separate polylines occupying the same space on my drawing layer, so maybe it was there all along and SU got confused by that, I certainly am...
I take it the file link works?

Here's a brief tut' on making Lathed shapes with EEbyRv2 - if you want a pure 'Lathed' Vase then use my Lathe.rb Tool - [Type D] instead... If the lathed 'rail' path isn't circular then make it an arc initially and then scale the mesh group later to distort it to suit ?

Thank you TIG for detailed answers, which helps to me , I am now able to make alot of mesh surface, SKETCHUP will eventually develop into a more powerful software than 3DMAX step by step,TIANK Again

I think Extrude Edges by Rails had replaced Extrude Edges by edges ,SO I use Extrude Edges by Rails only ,did you?
-
Hip-hip hooray TIG! Finally a patch tool for sketchup! thanks again TIG.

EEbyRails does most of what EEbyEdges can do ... but with EEbyEdges you can make groups of two sets of separate edges, arcs etc and they'll mesh with gaps etc - though that mesh is limited to one rail and one profile...
EEbyRails won't replace Lathe as the method and results are quite different... -
Any idea why on a MAC (os 10.6.2) and SU 7.1.58 the EEbyR plugin runs successfully then causes SU to go into a stall and then crash?

no, but I could test your 4 profiles on 10.5.8 and see if it's a 10.6 issue, if you want.
at first I had problems which I now think were caused by using one of Kirrel's or one of Chris's tool earlier in the session, since then I've been restarting once I've done the curve construction and haven't had any problems.

Same thing happens with Loft tool...it runs..then SU goes into a full CPU use and eventually crashes...

How many profiles/rails/faces are reported in the VCB area ?
Over ~2000 faces will take a while to format... -
It's something about the model as a whole...when I copy the rails and profile into a new SU file it works fine..so for now I'll do that and import the result back in...

Geometry sometimes gets muddled in the database.
Have you trued Model Info > Statistics > Fix Problems ?
Have you tried grouping a rail and immediately exploding it ?
Or Edit>Cut'ting a rail and Edit>Paste-in-Place in the same Model?
Or Edit>Copy a rail and the Erase it and immediately Edit>Paste-in-Place in the same Model?
Or rail Select and right-click Explode Curve and immediately Welding it again ?
These sometimes fix the -

I chose the semi-circle as a profiles,I finally get the same effects of lathe
here is test:
-
If 2face +2 path can do it, it would be a pioneering
-
Further to say, I chose as a semi-circular and semi-rectangular as their path, get the desired effect of lathe will not be able to do
