PrimSharp

https://github.com/merklegroot/PrimSharp

A C# library for Constructive Solid Geometry

Objects are rendered to OpenSCAD code.
You can paste the rendered code into OpenSCAD and use it to generate an STL file.

OpenSCAD

You can get OpenSCAD from here:
https://openscad.org/

Notes

Dimensions use Width, Breadth, and Height. I went with "Breadth" instead of "Length" to avoid conflicts with the word "Length."

Example

Running this:

newCube().RotateZ(45).ToOpenScad();

Gives you this:

rotate([0, 0, 45])
cube([1, 1, 1], center=true);

Note that the geometry isn't translated to OpenScad until the ToOpenScad() method is called.

Getting outputs

I usually just use unit tests to retrieve outputs for a model.
This probably isn't the best use of tests, but it works.

usingPrimSharp;usingXunit;usingXunit.Abstractions;namespacePrimSharpTests{publicclassBoxTests{privatereadonlyITestOutputHelper_outputHelper;publicBoxTests(ITestOutputHelperoutputHelper)=>_outputHelper=outputHelper;[Fact]publicvoidBox_with_defaults()=>_outputHelper.WriteLine(newBox().ToOpenScad());}}

Primitives

Cube - a rectangular solid

newCube(width:3,breadth:5,height:2);

Cylinder - you know what a cylinder is.

newCylinder(radius:2,height:5);

Simple Operations

newBox(4,4,1).Subtract(newBox(2,2,1));
