Plugin to do arc curve
-
Hello everybody,
in my work, i have to do a subway's tunnel, so i have to make all the curve of the subway...
for my curve, i draw a circle with his radius and i cut my curve thanks to the curve angle...
Do u know a plugin which make that automatically?it's not very complicated, but a bit long and it will be thanksfull for me...
thks in advanceNicolas

Hi Nicolas,
Is the Arc tool not sufficient for drawing arcs? (And if not, why?I mean just to find out what you are really after.)
-
sorry, but it's not your fault, but due to my poor english!
no, it's not what i mean,because its not a arc that i must draw...it's a turn, like you can see on my paint file!in fact i must go on the right or the left and not stay on the same trajectory like in arc's tool -
As "a picture is worth a thousand words" (especially when there are language barriers - I'm not a native speaker of English either),could you upload a couple of images - or even the skp file -so that we can see what you mean?
There are a couple of good plugins for different purposes like TIG also mentioned.

the tool 'weld' will be very useful for me, in the fact that i have many part of a line.
However, it was not the plugin i searched for...
what i must do is very long, because i have to make any parts of each inter-station of the subway with theirs turns, slopes and lines.in the reality, the subway turn left or right with a certain angle. i have this angle and the radius of the circle so i must take the arc who belongs to a circle with a radius of X meters and wich makes an curve angle of Y°, like u can see of my paint file.
As the time i made one line between 2 interstation, i search for solves in any part to make this faster, including do faster the turn, the slope,etc...
or make it automaticaaly with an excel file imported in sketch up....
Do u understand what i want to do?Sorry for my very poor english...
---edit---
an example of turn and my file skp of what i must do...

If it's a non-circular arc you can scale an arc to make it an ellipse.
You can also rotate arcs so they are not an an axis plane.
If you need a curve then join several different arcs into one piece using the ruby 'Weld.rb'
If you need curves that form a helix in 3D (the ends are not planar) then use ruby 'Helix.rb'
There are also several 'Bezier' tools....

thanks you very much, but it's already i do...but it's a little boring when it's too repetitive.That's why i was searching for a plugin, in which i just put the angle and the radius and i have my my arc
I already saw the arc tool and it's not what i search, because i have only the angle and the radius...
In fact, i have all my data of length,slope,etc in a excel file...
Do u think i can imported this file and make it automatically all the components (line, arc ,etc...) to just gain time...?
thx for advance -
Didier Bur has 'Arc.rb' tools that might also help... http://www.crai.archi.fr/RubyLibraryDepot/Ruby/em_geo_page.htm
You can use the circle tool and then construction lines and the protractor plus temporary lines etc to split it and make an arc with an included angle... I've made a tutorial...
-
it's interesting for me...how can i PM didier?what is his pseud?
-
"Didier Bur" without the quotes.
-
thk u! i will make this...i keep u in touch
-
It could be done... Why not PM Didier and ask his advice/help - he's a master at importing .csv data and making geometry AND 'arc' making...
