Graderworks software reads SOLIDWORKS files in batches and extracts the mass properties from the files systematically. Also, it extracts meta-data from the file such as creation date, last saved by, and save date.

Graderworks is extremely helpful to educators who teach SOLIDWORKS because it easily outputs information about each file that can be used for grading. This method is similar to how SOLIDWORKS grades the SOLIDWORKS Associates Test.

In addition, an advanced geometric similarity algorithm can be used to compare student's files against one or more "correct" files. The algorithm will automatically compute a similarity score which can be used for grading.

Catch Plagiarism

Meta-data from the files is automatically analyzed to find suspicious files. Four checks are preformed.

  1. Inconsistent “savedby” name. If one student submits several files, and the last “savedby” name is not the same for all the files.
  2. Duplicate “savedby” name. If two different students submit files with the same “savedby” name.
  3. Duplicate “creation date” for different users. It is unlikely (but not impossible) for two students to submit a file that was created at exactly the same day, hour, minute, and second.
  4. Creation date is less than two standard deviations from the average. Files that are old may be from the internet or a previous semester.

Grade Faster

Graderworks and Excel can fully automate grading of SOLIDWORKS part files. Graderworks extracts the mass properties and compares the geometry of each part to the correct answer's geometry. The data is export to a .csv file. Simple grading formulas use the data in the .csv file to compute a grade for each student. Setting up the equations is automated with macros within Excel.

Graderworks call help grade drawings by exporting each drawing to an image format so that you can assess the quality of the drawing using a lightweight image viewer rather than loading SOLIDWORKS repeatedly.

Graderworks and Excel can automate grading of rigid assemblies, but flexible assemblies will still require the instructor to open each file.

For each file type, Graderworks always checks for plagiarism.

In an analysis of a class of 100 students, Graderworks reduced the grading workload by more than half.

Gain Insight

With the mass properties and meta-data in a spreadsheet, it is up to you to find creative ways to use the data. For example, by subtracting the "last saved date" from the "creation date" you can see how long a student spent on a file.


Extract Data

Graderworks lets you extract data from hundreds of thousands of SOLIDWORKS files in a short amount of time. This data is then put into a spreadsheet so that you can analyze it however you want.
