If you upload the file, then someone can look at it and see if it is a working file, or contains errors.
When you start using a program, (and there is a difference between CAD and Drawing Programs, though the difference is getting less relevant for certain things) you must commit to that software, and really stick to it. If you haven't spend 6 months on an established program, you will never find a program that works. Perseverance is key, or taking a formal course. Learning this kind of software on your own is very very difficult. You have to document every step you take and make so that others can help you. You posts are too generalized and you find out very fast that you won't get the help you are looking for as you need to be more methodical.
In all honesty, if you don't have a technical background, the best thing to do is to make a box. Then try and unfold it. Make all the primitive shapes. If you make a box, and cannot get it to unfold properly, then you must go through every setting, including returning everything to default, and not continue till you get that step correct, and every single step afterwards.
Without a precise, methodical approach, you cannot succeed in any software you use. Even if you upload a file that I can open and manipulate, but you can't, it means your software is not set up right. Just one setting will mess everything up.
