Introduction

After 6 months of work, here is finally my first MFC program release. This program is a CAM simulator. I am not a software engineer, so please forgive me for errors. If you have questions please let me know. I am sure that you will find them. The lecture of data files was a big problem to me at the beginning, so here is the implementation. I needed to read *.txt files, what the CNC machine generate. Here is an example M X25 Y23 Z25 SPEED1500. This is a block of data, needed to setup the machines. This is a kind of language that the machine use to move on the coordinates over the work space. So in this implementation you can read a full document, splitting the block in the necessary X Y Z and SPEED values. This is my first upload, I have more things to say about this program I will try to improve soon, this short commentary.
