[Plugin] Extrude Edges by Rails
-
Hello...
First of all, is the first time I post here, so I want to thanks TIG and all for these fabulous SU plugs that expend SU possibilities !!!So, I use EEbyrails and other EE (and other plugs) for non standard architectural modeling. I use some other soft (MoI, Rhino, C4D, Revit...) but I want to use SU cause is the simply free way to teach 3D modeling to my students.
But, when I try to make a free profile helix EEbyrails have some problems :
http://d2design.free.fr/perso/helix.skp
If I to with helix as rails, some profiles are 180° rotated (I can manualy rotate to have the good result), an if I use the NURBS as rails, the profile is not the same along the helix.
Is it a bug or a problem with my model ?

I will say your curves but don't know why!
Ps Post also on the French forum
Go to your tab Private messages then Tab Users group then enable that you want

I tried with your file Pilou, and no problem
I dont know how you made your helix. Mine was made with dynamic componant with a single point inside, copied with some sin and cos formula in the X an Y value, and manualy joined with line finaly welded. This way to draw the helix perhaps cause the bug ?I also tried with odd number of point in the helix, so no point at 180° to the start position, and all it's ok.
So I know how manualy fix the problemPS@Pilou : Damned ! you know I'm french !

Sometimes curves are 'muddled' in the database and then exploding and remaking them, or cutting and paste_in_place or grouping and exploding them fixes this type of bug.
However, I tried exploding the curves and remade them with little improvement - same or very similar problems.
It seems to be a shortcoming of the script.
At least you know how to work around it - just pick different pairs of profiles and rails to get what you want.
I can't immediately see what's causing the problem - the algorithm for working out which end is next to which is quite convoluted as there are many permutations...
BUT it's puzzling as seems to work initially whichever order you pick in, but falls apart in some case at some points along the curve ???
The spiraling helix must make a few of the points rotated by 180 degrees too much/little in certain locations around the rails - It's probably fixable, but so rare it's not been reported before...
I'll look at it...

A new version is now available here http://forums.sketchucation.com/viewtopic.php?p=217663#p217663 which fixes the helical rail glitch that was reported...

Hi,
I have missed the website for a bit and I see this wonderful plugin!
I was waiting for that since long time....for many shapes i was still using rhino's tool:sweep2rails.
I am going to play with that but I want to ask:
I create due rails e my curve profile and it works well, but if I would like just a line rather than a curve....it looks like an error.
Sorry probably i have to read better, anyone has a simple answer?thank you.
-
I am still trying...but not results...
When i try to select a simple line rather than a curve (just the first step before the selection of the 2 rails), it is impossible to select anything, but if i draw a curve it wors immediately.
It looks like strange!
I know....it is a stupid error by me! -
I calll the plug then click a "line" first: no problem
Sure! you have not divided it!!!
'see my previous post! 
A simple line not divided can't be selected !
-
i've even downloaded the example file and the latest .zip and i still can't get this to work. the lines change colors, i get all the dialog boxes reverse...etc, but no result.
-
Thank you very much Pilou!
Job Done!
I needed so much that script working well because i need to create something like that:
I have seen something similar in this topic.
I need 2 different spiral curve and then a surface that run through the 2 spirals.
Any tips? -
No problem
Draw your 2 helix curves and just one "divided line"
Call the plug, CLick the line, CLick curve rail 1, click curve rail 2, click again the line!I suggest you to draw just one module then make a group or a component then copy past it!
-
Job done!
Thank you!
Quick and without problems!
I have tried to download the plugin "curvemaker" from the website http://www.drawmetal.com but the website doesn't work. Any info about that?
I think that could be a good plugin.thanks a lot!
-
Seems their addresses are changed! (expire in april)
so you must use another plug or draw your module curves by hand
-
Right click : divide your line ?
And weld them in any case or if you have several in connection!

does everyone have me on ignore?
this is the second time i've reported this. once a version or 2 back and it has never worked. -
Can you post your own file who don't work?

Thank you Pilou!

it's a pleasure
