.recx file format

A .recx file is Cutting Planner\'s proprietary file format, which is a .xml worksheet file that has been zipped and given a .recx extension. One .xml file is equivalent to one worksheet, so you do not need to be aware of the fact that it is a .zip file. You do not need to be aware of the fact that the file is a zip file, nor do you need to install separate compression and decompression software.
Generally, only the creator of a binary file understands the specifications of the binary format. Therefore, it may be difficult to reuse the data due to changes in the times. This software is a minor proprietary standard, and I think that leaving a large amount of data in this format will inevitably leave some concerns.
Therefore, we have changed to xml format. xml is flexible enough to accommodate future specification changes and extensions. By publishing the specifications, third parties can develop software to use the output tree plans in other applications. The advantages are as follows.
If you put extra files in the .recx, it may not work properly.
Multiple .xmls can be combined into a zip to support multiple sheets. The tab order is the order of the file list inside the zip. This allows you to create a multiple-sheet .recx file even on the command line by using the zip file creation tool.


As an example, here is an xml of the following data.

About parts panel and stocks panel numbers


Parts panels and stocks panels are sorted by area, and numbered starting from 0 in the order of size. If the area is the same, the longer side is numbered first, and if the area is the same, the rotatable side is numbered first.


About the Data Structure of 2D Diagrams


Cutting a board once results in two pieces. Cutting one of them will result in two pieces. In other words, the data structure is a two-branch tree structure.
The data structure can be expressed as it is by simply defining a "board" in xml. If you draw only the parts panels and unused space at the end of the tree structure, it will be as shown in the application.
If you have to read inconsistent values, Cutting Planner may not work properly. Only use the output values.


Regarding numerical values such as board size and coordinates for aggregated data

Due to the specification of the internal algorithm, the values must be integers. Therefore, they are converted to a number with the smallest unit being 1 and recorded. The value will be an integer with [Options]-[cutting optimization calculation]-[precision] as the unit of 1. For example, if the length format is a decimal point and the precision (minimum unit) is 0.1, 12.3 is 123. For fractional inches with a minimum unit of 1/8 inch, 12 inches would be 96 multiplied by 8.

Example of 2D code

The difference from 1D is explained in the comments section.
