solid creates a Model that's intended to represent a solid object, and supports a CSG command set.

Only if the input file is entirely flat geometry

It would be useful to create a new Polygon using Sketch's builder DSL without having to create a Sketch

For file formats that support Materials (SketchUp, COLLADA, etc)

The pass everything right now. Need to look into it.

That part of the code is getting rather large and it's probably time for it to move out and get a job.

A shortcut for creating a panel, instead of using the extrusion command. It should generate a subclass that can be detected during BOM generation.

I tried to manually install units-ruby since your units package is already missing.. Is this package compatible? I managed to install sketch 0.0.4 but, it still complains that it needs the sketch package

Looks like there's another name conflict on rubygems. Go figure.

At the moment, Polyline, Polygon, Rectangle, and Square are all exported as a series of individual LINE primitives. The DXF format has the LWPOLYLINE primitive for exporting connected chains of lines, and it should probably be used when possible.

The docs for the LWPOLYLINE primitive aren't exactly clear so I have a feeling that it may not be widely supported by other packages that manipulate DXF files. This may require some testing before proceeding. Or maybe an option should be added for disabling the primitive during export.

Not having these is getting annoying. I keep ending up with an Array in places I was expecting a Point or a Size. The type-checking is nice, but unnecessary.

Page 230 of the 2012 version of the spec says the HEADER section can be omitted if it is empty.

For some reason a bare sketch block doesn't allow any defined attributes to be used inside the block...

sketch :MySketch do
    attr_reader height: 5
    square height   # => NoMethodError: undefined method `height' for main:Object
end

assembly creates a Model, but doesn't imply that the Model is a solid object. Model will become a sort of implicit CSG construct, whereas Assembly will be collection of Models that are intended to interface in some fashion.

The concept of an Assembly partly overlaps the concept of a Group, at least in terms of implementation, but each captures a different developer-intent. A Group is meant to be a tool for organizing, or structuring, the code. Whereas an Assembly is meant to embody the more mechanical concept of parts that interface with each other.

Read in one format, write out a different one
