Sorry Im not a coder but an artist and I need to extract a 3d model from a pdf. I don't understand much about coding and all, so can you explain to me how to proceed in layman's terms? -I downloaded python -Opened IDLE and I ran the pdf-parser.py program -A window with some help instructions opens Now, I tried your line of code "./pdf-parser.py -t /3D input.pdf" and it didn't work, even if I change the /3D input.pdf to /my_pdf_file.pdf , I tried to use it without the "." in the beginning as well, to no avail. I've tried using just "pdf-parser.py -t pdf-file.pdf" and variations like "pdf-parser.py -t /c/folder/pdf-file.pdf" or "pdf-parser.py -t /folder/pdf-file.pdf" to no avail. My pdf is inside the directory C:TestFolder. How can I access it with the -t command in pdf-parser.py?
