I'm seeking guidance on automating the conversion of STL format files to BIN. I'm aware of how to perform this conversion manually in tools like Cloud Compare or similar software. However, I've encountered a few issues when attempting to automate the process using Python code.
The Python code I have does indeed convert the STL file to BIN successfully. However, the problem arises when I attempt to open the converted BIN format. It doesn't seem to work with any of the 3D software, including Cloud Compare.
Also, I have noticed a difference in file size when I manually convert STL to BIN instead of using the Python code. The manually converted BIN file tends to be larger, while the BIN file created with the code keeps the same size or even gets smaller.
I would be very grateful for any help, insight, or suggestions on how to properly do this conversion using the code or alternatively. If you have any experience with this or can offer any advice, I'm all ears. Your expertise would be invaluable.
