I am new to openscad and need to design some parts. But the view or render do not help me since I am blind.
So for me to be able to do anything I need to understand some basic stuff so please bepatent with me.
I do understand the coordination system so what I firstly need to make 100% sure of is if I create a cylinder and make center=true is the circle vertically placed with the center of the cylinder vertically going up the y axis and the bottom of the cylinder at x0,y0,z0.
Cylinder(d=5, h=10, center=true)
So in my head I see it as follow:
Left bottom of cylinder at x=-2.5, y= 0, z= 0
Bottom Middle of cylinder at x=0, y=0,z=0
Right bottom of cylinder x=2.5, y=0, z=0
Top left of cylinder x=-2.5, y=10, z=0
Top middle of cylinder x =0, y=10,z=0
Top right of cylinder x=2.5, y=10, z=0
Back bottom of cylinder x=0, y=0, z=-2.5
Front bottom of cylinder = x=0,y=0, z=2.5
Back top of cylinder x=0, y=10, z=-2.5
Front top of cylinder x=0, y=10,z=2.5
So it will give me a upright cylinder.
Do I understand that correctly?
Thank you

Hi Hendrik,
The rendered cylinder will be upright, with its very centre at the origin
(0,0,0).
The top of the cylinder is a horizontal circle of diameter 5 with its
centre at x=0, y=0, z=5 and the bottom of the cylinder is a horizontal
circle of diameter 5 with its centre at x=0, y=0, z=-5.
Hope this helps.
Regards,
Matthias.

No.
First: in the conventional orientation, X is left-right, Y is
forward-back (into and out of the screen), and Z is up-down. 2D objects
like circles are in the XY plane, at Z=0.
What you describe is the behavior with center=false. Cylinders are
always centered on X and Y. The "center" parameter on a cylinder
controls vertical centering. With center=false, they extend up from
Z=0. With center=true, they are vertically centered, so in Z they
extend from negative height/2 to positive height/2.
By the way: I think I've seen a video showing using OpenSCAD with a
tactile display. I don't immediately find it, but I do find a few
relevant-looking pages at
https://www.google.com/search?q=openscad+blind+tactile+display .
So if I change the following is it then correct?
Cylinder(d=5, h=10, center=true)
Left bottom of cylinder at x=-2.5, y= 0, z= -5
Bottom Middle of cylinder at x=0, y=0,z=-5
Right bottom of cylinder x=2.5, y=0, z=-5
Top left of cylinder x=-2.5, y=0, z=5
Top middle of cylinder x =0, y=0,z=5
Top right of cylinder x=2.5, y=0, z=5
Back middle bottom of cylinder x=0, y=-2.5, z=-5
Front middle bottom of cylinder = x=0,y=2.5, z=-5
Back middle top of cylinder x=0, y=2.5, z=5
Front middle top of cylinder x=0, y=2.5,z=5

Positive Y is into the screen; toward the viewer is negative Y.
Back middle top of cylinder x=0, y=2.5, z=5
Front middle top of cylinder x=0, y=2.5,z=5
You're missing a negative sign on the Y in the "front" case.

No Hendrik.
If center=true then the center point of all 3 axises will at x=0,y=0,z=0
and will extend one half of the dimensions you gave it in the x,y, and z
and -x,-y,-z directions.
Take care and stay well.
Hi Hendrik,
If you add 5.0 to all your Z dimensions I think you’ll have it the way you want.
You had interpreted centre = true as I first did (another novice), thinking ‘centre of the object’.

Ok, now I officially confused.
If center=true how does it work. For if I add 5.0 to my z then I add up with the same as what I had in the first place when I asked the question.
So let us try again.
Cylinder(d=10,h=20, center=true)
“You had interpreted centre = true as I first did (another novice), thinking ‘centre of the object’.”
Q: so where is the center then?
The rendered cylinder will be upright, with its very centre at the origin (0,0,0).
The top of the cylinder is a horizontal circle of diameter 5 with its centre at x=0, y=0, z=5 and the bottom of the cylinder is a horizontal circle of diameter 5 with its centre at x=0, y=0, z=-5.
So which one of these is correct?

Terry,
You are almost right.
For center = false a cylinder stands centered around x=0, y=0 and z = +h/2 ie it stands on the centre and fully above the x,y plane.
For center = true the cylinder is centered around x=0, y=0 and z = 0 so all 3 planes dissect it in the middle of the object.
Looking at the cylinder as rendered
Plus x is to the right
Plus y is away from you (you have this reversed)
Plus z is upwards
Now this is at odds with a cube which when centre=false is always drawn fully in the positive quadrant of all 3 axes and no part of it goes negative. But when center=true is rendered like a cylinder so all 3 planes dissect it in the middle of the object.
One point of caution the precision, roundness of an object depends on the values of $fa and/or $fn such that as an example $fn=6 draws a hexagonal bar and not a cylinder - upping $fn improves the roundness but ups rendering times
Hope that helps
Bob

Thanks it does. On the matter of $fn if I always use $fn=100 or higher will that always help in making cylinders and spheres round. Do not mind the rendering time because I will be unable to see and adjust my $fn to be correct. So looking for a safe $fn number to make most spheres and cylinders round.

Left bottom of cylinder at x=-2.5, y= 0, z= 0
Bottom Middle of cylinder at x=0, y=0,z=0
Right bottom of cylinder x=2.5, y=0, z=0
Top left of cylinder x=-2.5, y=10, z=0
Top middle of cylinder x =0, y=10,z=0
Top right of cylinder x=2.5, y=10, z=0
Back bottom of cylinder x=0, y=0, z=-2.5
Front bottom of cylinder = x=0,y=0, z=2.5
Back top of cylinder x=0, y=10, z=-2.5
Front top of cylinder x=0, y=10,z=2.5
So it will give me a upright cylinder.
Do I understand that correctly?
Thank you
Best Regards
Hendrik
