hello, when you re done can you provide us a tutorial or explainations of your method (what is the goal of the exercice, what are your hypotheses, how do you exploit the results etc ...) please ...

hello,
i know this software, but seems that it dont works on big model, now i'm searching for a converter reading u3d file (to 3ds or better skp), did you hear about this kind of software ??

hello,
strange to, i'm new in sketchup (but not in CAD), i was searching for a job on my small island (Reunion island, in indian ocean; french dept, no industries in here !!!!) after leaving Paris (france), a client offers me 600 euros per day (about 850 usd!!!) (first contrac of 4 days) to draw a terrain (mesh is given) whit a field of solar panels, i have to animate then (regarding position of sun) like a field of sun flower.
The output is a 3d pdf file whit boton to control animation ...
My feeling is that is a lot of money, but in here no body is able to give a 4 dimensions file (like here select umid_M2.pdf
what do you think about ?

good idea rv1974, kind of : "select string edges", useful for complicated shape

i'm really suprised that framerate grows 4 times from 7.0 to 7.1 on normal xp for shaded and 15 times for shaded whit textures whit virtual box ...

whit pictures of rendering and of model (whit hidden geometry) can be helpful...

hello,
did you try to turn edges quite white (1 or 2 on rbg scale) ?

THANK YOU SO MUCH
It helps me a lot to finish this drawing, i've give up some months ago ...
i bet it will be the most used plugin for me (whit weld.rb) ...

what do you think about :

lot of faces may be created, would you try the method of distribution of wedges whitch decrease the number of created face?
|_no "continue whit classic algorithm"
|_yes "open another dialog box"
_|_how would you like to distribute the wegdes
__|_from start "all from start to middle of rail"
__|_from end "all from middle to end"
_| homogeneous "..."
_|_ok
_|_cancel

do you think is a good way?

EDIT : is not a good way, i was thinking about low difference between segments's rails, but dont works for big difference ...

Hello, my question is about the supa plugin named ExtrudeEdgebyRails?
I would like to understand exactly how it works, because sometimes when you use 2 rails whit different number of segments it increase seriously the number of meshs...
i heart that the big brother of EEbR, ExtrudeEdgeSbyRails2 is on the way, i imagine that the problem of the number of meshs will be more heavy on this new plugin...
i think EEbR if based on ExtrudeEdgebyEdge, isn t it ?
working from EEbE and compare to EEbR is a good way of research, any idea ?
so that's why i would to know if it s possible to think about ways to improve ExtrudeEdgebyRails?
i ll post some pics to show what i mean by improve
Keywords :
-EEbE : ExtrudeEdgebyEdge (by TIG)
-EEbR : ExtrudeEdgebyRails (by TIG)
-Segment
-Profil
-Point
-Rail
-any suggestions ?

Guideline : translate what is beautiful (from designers) to maths (for developers)

post the picture whit a sampleimproveEEbR1.skp
how to EEbR whit a difference of one segment between the 2 rails?
picture 5. and 6. : there are 5 ways to merge the difference one segment between the 2 rails. i use first EEbE whit the profil and the bigger rail (in segments number), then i ajust each line (profil) (whit scale tool) to the smaller rail.
(Anyone knows a simple way to select the profil in one click or 2 ?)
does anyone (who wants to contribuate) need to know how to go from step 4. to step 5?
Now drafters, we need a more complicate sample (rails : less than 20 segments, difference of 5-6 between rails, wee will increase step by step), and your design background, any ideas ?

here is my 3rd try, and it's unacceptable.try3.skp
i think i will focus on ExtrudeEdgebyRails and create a topic named "can't we improve ExtrudeEdgebyRails?"

topic : can't we improve ExtrudeEdgebyRails? here

@Jeff Hammond
the fastest way if you use opposite border curves whit same number of segments is to use ExtrudeEdgebyRails, (egde is the left profil and rails are the top and bottom profil).
Then select the horizontal lines one by one and scale each to the blue, red, green direction to ajust it to the right profil ... need a picture? (i ll post it this evening)

I think EEbR works like this :

• select a profil then 2 rails
• the 2 rails are divided whit a common number, the number of point of each rail multiply together (a segment is 2 points, 2 consecutive segments are 3 points etc).
• the plugin calculate now the lenght and the orientation of the segment formed by the first points of each rail, then the second points, etc...
• the lenght of this segment give the scale (homogen) of the profil and the orientation give the ... orientation
  I will try to mesh more nicely at my own aprecia, i will start from the two bigger curve, then extrude edge by edge (or follow me tool) and scale, rotate each profil and sometimes merge some points :the file
  My feeling is that EEbR should be modified to make this work (i think it s basical mathematics) before publishing ExtrudeEdgesbyRails2, because the size of the mesh will exponential and crashing SU.

nice job ely862me,
there are several ways to draw this

did you modify the orginal curves ?
i try whitout modify them.
@ Jeff Hammond, you should create you contour by copy, move, rotate and scale, by this way this possible to do it just whit sandbox.datdere.skp

edit : add the curved plane groupeddatdere_curvedplane_grouped.skp

ely862me says : "First of all make sure u have same numbers of segments on the opposite curves ."
or the result of division gives an integer (bigger number of points / smaller number of points) => using extrudeedgebyrails

edit : Actualy extrudeegdebyrails doesn t support it ....

hello,
just like that ?

Thank you for your fast replies, first i tried line2tubetool then ghostcomponent, it work only for tube along blue red and green axis then i read the replies and try line2tubestool whit 4 sides (precision is sides), and all the tubes are rotated of 45 degres ... so i have to rotated then ... so long for a so small structure ...
Pipealongpath don t works on the all lines and have the same rotate problem.
Profilbuilder looks great
I just discover that soften edges works outside the group or component (several groups or components too), i start using su in juny

hello,
i need a plugin like line2tube.rb could be named "line2sectiontube.rb" see attachment KIOSQUE_BERTRAND.pdf
i need to transform all the green lines to tube square 40mm.
do you know a plugin doing that?
thanks

hello,
when you are in a component change render mode for "wireframe" then hit ctrl+A to select all (edges only because you are in wireframe mode), then goto edit > hide.
return to "shaded whit textures" render mode .
hope it s helps
