            QUESTION

            How to represent/read a cube in dxf file?
            Asked 2021-Jul-06 at 12:59

            Trying to open a dxf file format (actual project in C++), I could understand the basic structure of the file, but I can't manage to find how a cube is actually represented.

            For a cube in CAD, I expect at least 9 values:

            • X Y Z position
            • A B C rotation
            • W H D size of the cube

            I expect X, Y, Z, A, B and C to be in the ENTITY section,

            But Looking at example files, I see many settings, the preview image (taking a significant space in the file), layouts, etc.. But nothing that I can match to how the cube is actually build.

            Question:

            How to represent/read a cube in a dxf file?

            More info

            Here is the documentation about the file format:

            Here is an example of file with a cube (created with BricsCAD). Unfortunately, I can't embed the file, as it is too big. The "cube" is of 20mm x 25mm x 30mm.

            https://download.escain.org/example_cube_20_25_30_mm.dxf

            I checked LibreCAD source-code, but it does not manage 3D models. Also, libdxfrw library is too generic (it just call the interface callback with the full Entity data).

            This cube is embedded binary ACIS data (3DSOLID) and can not be interpreted without the libraries from Spatial Inc. For more information see my answer to another question: How I can parse nurbs surface from dxf file? Or do you know library(for js, if exists or any other language) for parsing it?

            EDIT: Find binary data of ACIS entities

            Starting with R2013/AC1027 Modeler Geometry of ACIS data is stored in the section ACDSDATA in a ACDSRECORD these records have no handle, instead they have an ID. The record of your 3DSOLID starts at line 22393 and has the ID 10:
