2020 Spring Special F4 CADathon - Results Posted

image
Hello everyone,

F4 is pleased to announce that we will be hosting our 2020 Spring Special CADathon from 6pm Eastern of Sunday, Apr 12 - 8pm Sunday, Apr 19th. These dates were selected based on the responses from this poll . The live show will be featuring a brand-new panel of judges and will be streamed on April 28th at 7pm eastern on the First Updates Now (FUN) twitch channel!

Watch Live on the 28th : https://www.twitch.tv/firstupdatesnow

There will be giveaways for those who watch live, and prizes for winners of various awards. Stay tuned for further information on this.

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 , or eigth CADathons.

Team information (these rules have been changed for this special CADathon):

  1. The CADathon duration has been increased from 3 days to 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 file, native CAD files, and any renders they 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 April 19th. 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.

Sign Ups close on April 11th at noon but please sign up as soon as you decide to participate.

Sign up form:
Regardless of what type of team you are (solo, 3 man, unlimited FIRST team, etc), ONLY 1 MEMBER OF EACH TEAM SHOULD COMPLETE THE SIGNUP FORM.

If you are competing as a FIRST team, and a member of your team has previously competed in CADathon, the team may use that member’s CADathon team number if they wish, by selecting the “existing team” option.

Excited to try my hand at Cadathon, I had a question about how teams do such nice renders. What kind of programs do you use and are there any tutorials?

Keyshot is a favorite.

I use Solidworks Visualize and had a lot of success, I’ve seen really nice confusion360 renders, and Keyshot makes beautiful images. If you’re feeling like doing a lot of work in return for obscenely high quality renders, blender is a thing that exists.

As much as I hate to say it (I love blender) for high quality cad renders I tend to like software like 3ds max for its better cad import capabilities. To get CAD into blender in a convenient format takes a bunch of annoying conversion (Inventor into 3ds max as .iam and then export .fbx from 3ds into blender). Theres a lot of waiting and general slowness in these conversions so until blender can import more formats I wouldnt necissarily recommend it in this use case.

Just a reminder, signups close today at noonish.

The winners of Caddathons 2,3,4,5,7 and 8 as well as the finalists of 6 use Keyshot. It’s free for FIRST teams and is a great way to make high quality renders quickly.

Do you have the link to where you can download Keyshot for free?

You email Support@luxion.com and explain that you are a member of a FIRST team looking to use Keyshot. A Keyshot rep will follow up with a download link and instructions on how to obtain a 30 day non- trial license key. The 30 day key can be extended by sending your rep renders made in the program.
