For those unaware, a CADathon is like a hackathon but with CAD. People/teams are given a short period of time to CAD a specific thing (in this case a robot) ending with a panel of judges selecting a winner. If you would like more information on the CADathon check out our second , third , fourth , fifth , sixth , seventh , eigth , or 8.5 CADathons.

Team information:

  1. The CADathon duration is 1 week.
  2. There will be no limit to CADathon team size IF everyone on the CADathon team is a member of the same FIRST (FRC etc.) team.
  3. For CADathon teams with members of different FIRST teams, we will keep the usual rule of “up to 3 members” (this is to prevent the 10 best CADathon participants from 10 different teams from teaming up and making the competition unfair).
  4. If you are competing solo, but would like to be assigned up to 2 random partners, you can sign up as a “random” in the signup form and we will do our best to match you with a partner using the same software and in a similar timezone.

Submission requirements:

  • Teams will be required to upload a exported STEP or Parasolid file, native CAD files, and any renders they choose to create to a grabCAD workbench.
  • Teams will also submit a google forms “pit scouting document” which will help explain their design to the judges.
  • All files including finals renders need to be submitted by 8pm on August 16th. Once done, the files will be inspected to make sure they adhere to the game rules.

The submissions will be split in thirds and each judge will judge 1/3 of the submissions. Each judge will them submit their top 5-7 teams, and the other two judges will go back and judge those entries. This way the top 15 will have feedback from all 3 judges.

The only prerequisites to join are that you are willing to spend time doing it and that you have access to some CAD software. You can be any age (this is not limited to students) and we encourage everyone from newbies to the most advanced CADers to put their skills to the test. If you are new to CAD and would like to be on a larger team to help yourself learn, please contact us as these will be handled on a case to case basis. If you are interested please sign up at the link below.

We have moved the CADathon chat from slack to discord. Please be sure to join the slack to be up to date with answers to Q&A questions and interacting with other members of the CADathon.

The end of the poll still says to join the Slack and not the Discord, just figured I’d tell you in case you wanted to change it.


Team 576 cannot compete during this time, but can’t wait to see all of the awesome submissions!

Team 420 is excited to be back at it again!


Wish I was able to compete this time around (thanks furlough for ending). Good luck to those competing!

Are names of CADathon participants always released? I was under the impression that you generally don’t want to release last names of minors due to some privacy laws or something.


Yup, we’ve always released the names as they were entered while signing up. We don’t require that last names be provided when signing up. We leave it up to the participants to decide what they want to disclose and be shown on the stream (which is why many of the names are only first names).

In case this was unclear, we will make sure it is even more apparent from here on out.
