Hey All,

Please don't post this anywhere prominent, but I'd be thrilled to have
you test the web version of ImplicitCAD: www.implicitcad.org.

A gigantic thank you is due to Rob Gilson who made the beautiful web
interface for ImplicitCAD.

I'm also grateful to Rob's employer, Dream Forge, which has provided
an EC2 instance to accelerate rendering of objects. And to the Haskell
community for awesome libraries and helpful advice.

Please respond with any problems you run into!

Chris

I'll look at it soon-ish . :)

Can't get translate to work. Here's the code I'm working with:

module Post()
{
    difference()
    {
        cylinder(r=8,h=28);
        cylinder(r=4,h=30);
    }

//translate([28,0]) Post();
//translate([-28,0]) Post();

translate([28.5,0])
  difference(){
    cylinder(r=8,h=28);
    cylinder(r=4,h=30);}

translate([-28.5,0])
  difference(){
    cylinder(r=8,h=28);
    cylinder(r=4,h=30);}

The commented out section is my first attempt. Then I tried long hand.

Nothing fancy used yet... :)

It isn't that translate doesn't work. It's that fixing semantic
insanity of openscad means there isn't any implicit union. So use the
following instead:

union(){
translate([28,0]) Post();
translate([-28,0]) Post();

I wasn't aware any unioning was happening.

I just wanted to see if they looked right before placing another piece.

I had recently found on someone elses script that outputting two connected
object would create a joined stl.

But I didn't think that was proper.

Wouldn't have thought unioning would be needed for two (currently) separate
parts either.

Will continue with your suggestion.

Thanks,

Lance

Ok,

New weird thing.

I have to give either the difference of the union a parameter of 1 or the
holes don't go all the way through...

Lance

Adding a cube to the mix, and rounding the junctions, I get some nice
sweeps on the top side.

However, I'm getting some strangeness on the bottom where it needs to be
flat. :(

Code:
union(5)
{
    translate([28,0]) Post();
    translate([-28,0]) Post();
    translate([-30,5]) cube([60,100,10]);

Am I going to have to make it a little thicker than planned then use a
difference to smooth the bottom?

This code produces Interesting and unexpected results.

  union(5)
  {
    cylinder(r=6.25, h=87);
      translate([0,30,0])
        rotate(a=[19,0,0])
        {
            cylinder(r=6.25, h=90);
        }
  }

Hey Lance,

Thanks for playing around with this. I think what you've really
unveiled is that I don't have good enough documentation. This is a big
failing that I need to address.

Your problems earlier were due to too low a rendering quality. Add
$quality=8; and things should work better.

The bug with rotate is known and I really need to fix it.

Sorry about delayed responses, I was on a retreat.

All the best,

Chris
