This works for me. I bought some files to make an airplane, and they prepared GCode for this in addition to the stl files, factory files, they did a great job. So I printed the first GCode file and I had problems. So I had to use their stl files and rotate, split, etc to work best for me.
But I didn't want to do this with every file they provided,because the probably did a good job with all their other files, so I wanted to predict whether they will print first.
Thanks, I appreciate the chance to see what I am about to print first, a reasonable desire which you have fulfilled!
