How to confirm that CAD files were not imported?

Anonymous — Sat, 29 Feb 2020 03:35:32 GMT

Recently, I created a CAD model for a simple car for a class project. However, my design teacher thinks that I cheated, by importing files from the Internet. She thinks this because in the version history, for the first and only version, it shows the full model rather than the "steps". However, this is only because Fusion does not autosave, and I did not save while i was working, because I finished the quite simple model in one sitting. My teacher does not believe anything I say, and I do not know enough about the workings of Fusion 360(other than actual modeling) to make a good argument. Is there a way that I can prove to her that my work is indeed my own? (functions that fusion has, etc.)

The most obvious for me is, sketching in Fusion.

Most sketches imported will not have constraints and dimensions, and are made up of hundreds of short blue lines,

If your sketches are fully defined, black lines, has curves and splines in them, then that would be a big step.

Otherwise you are up the creek without a paddle, the Modelling side of things is similar in most products.

Did you use T-spline, because they are less generic.

Might help....

The obvious answer is to have you and your teacher sit at the computer and you create a model from scratch. It would be best if the teacher chose a different subject.

Attach your file here.
I have been grading student work for more than 25 years.

My sketches are indeed fully defined, and are black rather than blue.

Hi,

From my point of view, there are two questions:
1. Has the "teacher" defined for the task in which form the "student" has to provide proof of independent performance?
2. In other words: Can the "teacher" prove that the performance of the "student" was not independent?

good luck

No, many of them are not fully defined.

The image you attached in no way would support this statement.

That statement would be a major red flag to me.

I can't say whether you did the work or not.

It is poorly done student work.

If I were your instructor - I would know immediately whether you had followed the techniques that I taught in class (my students would never use these haphazard, undisciplined techniques and would not even know how, as you have done about 10 times more work than necessary - they would use it the easy BORN Technique).

Did your instructor cover the use of Joints?

I appreciate your feedback, however please note that my mediocre-looking CAD(in your opinion) is due to my very small amount of experience, being a freshman in HS using CAD for the first time in an educational environment with no prior modeling experience. How does one tell when a line is "fully" defined? I would like to refer to my designs so I can see what you mean.

Also, we have not been taught how to use joints. Most of my knowledge of CAD is self-learned, and I was not even aware of the BORNs technique.

That is what I figured. I will create a video tomorrow and then you can teach your instructor how to use Fusion. That should convince her.

Are you still here?

I have created a 25 minute video on modeling the assembly, but if you have moved on to other work I won't bother to compile the MP4.
