OpenSCAD is an open source programming language and IDE (Integrated Development Environment) for parametric 3D design. It is used to create precise, customizable and easily modifiable designs ready for 3D printing. It has a growing developer community and is the tool used to create designs compatible with the MakerBot Customizer app: http://www.thingiverse.com/apps/customizer
You can download OpenSCAD from www.openscad.org/downloads.html
This group is a place to discuss all things OpenSCAD including (but not limited to) new features, techniques, questions, libraries, works in progress, etc. So post a new Topic or contribute on an existing one!
Share knowledge, get constructive feedback, and ask questions!
Join to add your OpenSCAD designs or libraries to this group's Things. Non-OpenSCAD designs will be removed.
Hay guys, I only just noticed these quirks to do with inputting arguments, and was curious to know what other people made of them, would you consider them bugs?
Within the parenthesis of a function, If you put a labeled variable in front of an unlabeled variable, (even if it is in sequence) this seems to foul up the operation.
The label might be redundant, but I don't see any need for it to break the code. see (Example 1)
I've only looked at the one shape but I notice with the cylinder that without labels the second vale is assumed to be "r1" rather than "r", which means there is no specified value for "r2" so it is given a default value of 1. see (Example 2)
I think this one probably does constitute a small error.
// Example 1
function add(a,b,c)= a+b+c;
echo("test 1 = ",add(a=4, b=4, c=4)); // = 12
echo("test 2 = ",add( 4, 4, 4)); // = 12
echo("test 3 = ",add(a=4, 4, 4)); // = undef
echo("test 4 = ",add( 4, b=4, 4)); // = undef
echo("test 5 = ",add( 4, b=4, c=4)); // = 12
echo("test 6 = ",add( 4, 4, c=4)); // = 12
// Example 2
cylinder(h=10, r=2); // fine
translate([6 ,0,0]) cylinder( 10, 2); // wtf?
translate([12,0,0]) cylinder( 10, r=2); // fine
I'm aware there are workarounds to this problem, but I was wondering if it is possible to read/extract the name of a variable, not just its value?
echo(str("This variablei's name is ", extractName(X), ". value = ", X));
aboutVariable(box_height); // = "This variablei's name is box_height. value = 24"
Building customizable shape that can be used in TinkerCad or other simple software.
I need a simple shape generator that can create a series of points on its up-facing surface. I imagine using this as a simple "tree support" generator for Slicing software that can not make "tree supports."
For example I could put a circular disk down on the workplan and the pull the shape up to make it taller. As I pull it up, spikes/points would be created.
