Exciting engineering challenges with great prizes

Show off your skills and solve real design problems

CyDesign Part 1: Detroit Diesel DD13 Engine

Given simply an image of the Detroit Diesel DD13 engine, can you produce a detailed surface model? If so, cash in on your skills. CyDesign is launching 6 challenges, each with a different engine or transmission up for modeling. Each of the 6 challenges has a $500 prize for the best model. Win all 6 challenges and you could have $3,000 by the end of the week.

CyDesign is populating a small library of engines and transmissions used in the modeling of vehicles and vehicle capabilities. Currently, they have a few pictures and 2D graphics of these select engines and transmissions, but need to have 3D CAD models for each engine and each transmission. This challenge centers around modeling the Detroit Diesel DD13 engine.

No internal surfaces or components are required- only external surfaces must be modeled and rendered.

Dimensions (H x W x L) 53.0 x 51.5 x 58.3 in

A simple google search can pull up additional pictures and specifications as needed.

Requirements

  • 3D CAD models submitted should be similar in fidelity to diesel engine and diesel engine

  • Models can be done in any CAD software as long as STEP files are uploaded

  • The 3D CAD models only require external surfaces rendered; no internal surfaces/components needed/required

  • Mono-chromatic coloring with minimal shading required; do not need multi-light source shading. 3D CAD models only require one axis of rotation

  • Uploading CAD files of rendered models without permission to your GrabCAD profile is not allowed

  • The submissions will be judged on realism, creativity, composition and file size (smaller is better)

Rules

  • The competition is open to everyone

  • Team entries are welcome. In case of team win, prize money will be transferred to team leader who is solely responsible for splitting it among team members

  • You may submit several entries

  • Tag your rendering with “3DCADSTP” when uploading it to GrabCAD

  • All 3DCAD files have to be public

  • Only models uploaded to GrabCAD library will participate in the competition

  • Only models uploaded through this challenge page here will participate in the competition

  • Entries to be submitted as .stp files

  • The competition ends 8/10/12

Prizes

$500 for most realistic 3D CAD of the model provided

About the jury?

Submissions will be judged upon timeliness of submittal, accuracy of 3D models relative
to picture(s)/diagrams/images provided and file size of final CAD file (smaller is better).
The judges will be comprised of CyDesign and GrabCAD staff.

About CyDesign

CyDesign is developing a physics-based modeling system that will let the engineer quickly assess design options against requirements during the conceptual design stage.

Should the vehicle have conventional or hybrid drive? How will thermal loads affect an implanted medical device? By providing answers to these questions early in the design, a more robust and reliable system will be built.

CyDesign Studio will help the engineer manage key requirements, keep them pertinent to the design, explore the trade space of possible design alternatives, assess the viability of these alternatives, and provide guidance resulting in a much better final product.

    I just want to make sure the Engine we're modeling is the Detroit Diesel DD13 right? I ask because couple of the images shown above are DD15's

    @Kira, we will update the figures; yes, we are needing the Detroit Diesel DD13 engine to be modeled. The majority of the figures have "DD13" labeled on the engine cover.

    @Romano, we are looking for a very efficient contest, hence yes, we need to end the contest this week (Friday, 8/10/12). Thanks for checking

    Regarding the size of the model. Is it acceptable to only upload the assembly of the model w/o its constituent parts? If this is possible, i'm planning to just convert the whole assemble into a single part and upload that instead.

    in my opinion, the best way to take advantage of the grabcad community would be to break this huge task into smaller tasks and give a smaller amount. for example, oil pan $25, fan $25,transmission $100, etc.

    @Kira,

    Yes, only need the final assembly for the use ; uploading a single file would be fine.

    thanks

    re: "Uploading...." ; the goal is to make sure the files uploaded are viewable to the community and judges. Need to make sure permissions are correctly set.

    @Allan
    re" "do you want CAD files...."; the .stp files from the selected design are meant to be used by a Unity 3D player. I am not requesting the actual .3ds/.dxf/.etc files at this time.

    @Allan - my team is using the .stp files for viewing and other efforts, so we are using a conversion utility.

    i am not able to understand what to do?

    do i have to submit a 3d cad model in .stp format made by myself.
    or
    i have to render the models whose link is given on this competition page.
    or anything else.
    please reply

    @Abhijeet - no plans available ; attempts to contact mfg were unsuccesful, hence the effort with the awesome GrabCAD community.

    @farzin - 5 more contests start today, with a 7 day length.

    @Ian - this contest ends today ; i will be happy to review submissions that come in as late as 12 mid Pacific time (California).

    naveen thontepu about 13 years ago

    by reading i understood that its a great comp
    but can u clearly say what we have to design for the comp do u need just the fan, the outer cover and the oil pan or
    do u need us to design the images that are posted up to the miniature detail
    clearly me up with the fast.
    thank you.

    @naveen and others - given the short timeframe for these contests (5 more start soon), i know that the amount of detail that is possible is limited, not infinite. the second entry is heading the in the right direction, use this as the best guidance i can give.
