Code Sample Descriptions
Parametric Bolt Module
module bolt(length=20, radius=3) {
cylinder(h=length, r=radius);
sphere(r=radius*1.2);
}
// Example usage
bolt(30, 4);
translate([0,10,0]) bolt(15, 2.5);
An OpenSCAD macro (module) that generates a simple parametric bolt with customizable shaft length and radius.
Gear Generator Macro
module gear(teeth=12, radius=20, thickness=5) {
for (i = [0:teeth-1]) {
rotate(i*360/teeth)
square([2, radius], center=true);
}
extrude(height=thickness)
circle(r=radius);
}
// Example usage
gear(16, 25, 8);
A simplified gear macro to generate a 2D gear profile extruded into 3D.
Frequently Asked Questions about Openscad-macros
What is Openscad-macros?
OpenSCAD Macros are reusable script blocks within the OpenSCAD CAD platform. They allow users to automate repetitive modeling tasks, create parameterized 3D models, and organize code into modular components for easier design and customization.
What are the primary use cases for Openscad-macros?
Creating parameterized geometric shapes and components. Automating repetitive modeling tasks. Building modular designs for assemblies. Sharing reusable design blocks within teams or online repositories. Generating variants of a design with different parameters
What are the strengths of Openscad-macros?
Reduces repetitive coding and errors. Simplifies creation of complex, parametric models. Encourages modular and organized design. Reusable across projects. Easily shareable with the OpenSCAD community
What are the limitations of Openscad-macros?
Requires learning OpenSCAD scripting syntax. No interactive GUI design for macros; fully code-based. Limited debugging capabilities compared to full IDEs. Macros cannot execute code outside OpenSCAD context. Complex nested macros may become difficult to manage
