It’s nice to work with a board where you have detailed data like this. The .CST file is broken into binary sections placed end-to-end with trailing metadata. Most sections are the same format: they start with a string identifying them, and an integer number of fields. The fields then follow with infix delimiter constants — that is, each section has some constant bytes, and these bytes occur between every field, but not after or before. Most sections have fixed-length fields, but not all. Here are some idiosyncrasies: - The list of net names follows the list of footprints without a section header - The list of board edge lines follows the list of copper lines without a section header - The list of shapes has variable-length fields and may be missing entries The list of shapes is the most complicated section. Each shape has a type and a list of parameters, which have different meaning depending on the type. Each shape has a unique number and some of the shapes reference others. However, the use of the shape list is not complicated. Each component uses the same types of shapes. So you don’t need the whole thing parsed to use it. Y’know I might be able to remember a lot of this if I keep typing unsure if I wo;;
