The Basics of 3D design
Tamsyn Michael
So I have installed Blender, but have no idea where to start. I have heard that perhaps FreeCAD or TinkerCAD or something might be more in line with a beginner? Does anyone have any idea where I should begin? What software? Preferably something with step-by-step tutorials?
Thanks,
Tamsyn

TinkerCAD has tutorials built in, I recommend it as a starting point. Especially for making objects for printing.
Blender is pretty hardcore. I've learnt and forgot how to drive it numerous times. I'm currently in the forgotten phase.

Yep, Blender has a steep learning curve!
If you've ever messed around with PovRay, openSCad makes sense, but you really need a handle on CSG!
I was looking at the syntax, its "almost" like povray, the concepts are the same, just the syntax is a bit different.
I've found if you can't draw what you're desighning on graph paper, you WILL go nuts trying to draw it in a CAD program.
Besides you should make a token effort to get the ruler, pencil and rubber out!
This is a real object, not a model for an animation!

And have nearly finished making a glass based on the ANAT logo.
Here's my code for those interested:
union(){
rotate([0,270,0])linear_extrude(height=24) polygon( [
[0,0],[30,0],[30,5],[5,15],[30,15],[30,19],[0,19],[0,13],[21,4],[0,4]
] , [ [0,1,2,3,4,5,6,7,8,9,10] ]);}
difference(){
translate([-12, 10, 0]){cylinder(80,5,25);}
translate([-12, 10, 10]){cylinder(80,5,25);}

difference command so that there isn't any of the N inside the glass.
:(
Oh, it's based on the ANAT logo:

That code is really close to povray or a renderman client like yafray or aqusis

Thanks guys. I'm finding OpenSCAD much easier. I'm currently reading this:

If you make a Union of the N and the outer cylinder, then subtract the inner cylinder from it with difference, I think it produces what you want.
You might need to do a "proper" render with F6 for it to look right. The "fast" rendering get's a little confused.
difference(){
union(){
rotate([0,270,0]) {
linear_extrude(height=24) {
polygon( [
[0,0],[30,0],[30,5],[5,15],[30,15],[30,19],[0,19],[0,13],[21,4],[0,4]
] , [
[0,1,2,3,4,5,6,7,8,9,10]
]
);
}
}
translate([-12, 10, 0]) {

Here's where I ended up:
difference() {
rotate([0,270,0])linear_extrude(height=24) polygon( [
[0,0],[30,0],[30,5],[5,15],[30,15],[30,19],[0,19],[0,13],[21,4],[0,4]
] , [ [0,1,2,3,4,5,6,7,8,9,10] ]);
}
translate([-12, 10, 10]){cylinder(80,5,25);
}
}
}
I was trying to do what you did, Pix, but couldn't will try and find
out what I'm still doing wrong tomorrow. I could swear that,
following all my myriad brackets back to their source, it should do
what I want. :(

stage Steven, but because I failed to press f6 I thought the artifacts
were my fault. Protip about the f6 - thanks!

You should look at the CSG section of the povray manual, it will make sense after

Ah, that looks more like the code I got from one of the examples Pix.

}
translate([-12, 10, 10]){cylinder(80,5,25);
}
}
...
Still having a problem with the difference, just a separate problem.
