Show off your skills and solve real design problems
Given simply an image of the 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 that needs 3D CAD files generated 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 very quickly!
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. Each challenge centers around modeling specific engine or transmission.
No internal surfaces or components are required- only external surfaces need to be modeled and then rendered.
While images are provided for a starting point, these might not have as much detail as desired.
A simple Google search can pull up additional pictures, images and specifications as needed.
THIS CHALLENGE CENTERS AROUND MODELING THE HONEYWELL AGT1500 ENGINE
3D CAD models submitted should be similar in fidelity to those shown in these already created GrabCAD solutions: diesel engine and diesel engine
Models can be done in any CAD software, need to have STEP/.stp files uploaded as final submittal. 3D Studio Max compatible files are also acceptable if you are unable to produce .stp files
The 3D CAD models only require external surfaces modeled and rendered; no internal surfaces/components needed/required. The final uploaded .stp file only needs to be have the assembled model without the constituent parts
Mono-chromatic coloring with minimal shading required; do not need complex, multi-light source shading
3D CAD models 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 and composition
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 multiple entries
Tag your rendering with “HONEYWELL” 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
.3ds files also acceptable
This competition ends 8/17/12
$500 for most realistic 3D CAD of the model provided
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.
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.

Hi to everybody. I really love this website, I studied Physics but now I am unemployed so I have plenty of time. I wanted to ask you if you think that it would be possible to create the 3D model that CyDesign is searching for with the open source software FreeCad, or Is it necessary to use comercial software?. As I said I have plenty of time and I would like to learn about CAD, if you think that FreeCad is a good tool I´ll start tomorrow to learn about it, obviously I don´t expect to win the challenge but it´s something interesting and encouraging, and I would like to try it, with some months of work maybe I´ll be able to win these challenges.

Hi Jacson,
Yes, you can make the model in the software called 'FreeCAD'. I've searched a bit and found this software can export models to STEP and IGES formats. As long as CyDesign is looking for the .stp format, you will be able to do it with this software.

Hi Jacson, Mohomed is right just beat me too it, Freecad can save to IGS, STEP and STL.. CyDesign require a STL file only, so it shouldnt be a problem using FreeCad
jon jacson over 11 years ago
Thank you very much Mohomed and ALan, I´ll try to learn how to use that software.

what about dimensions?
stefan chesney over 11 years ago
I see that the image given is a cutaway. is the final product expected to be a solid shell or a cutaway as shown?
David Hinz over 11 years ago
hi all,
the final rendering and model is to be ONLY the outside surfaces. the two pictures/images are the only ones i could find; if the GrabCAD community finds better ones, please do not hesitate to let us know.
thanks,

All,
Remember, do not need internal components of the engine, even though they were provided in the limited images. Only need the external surfaces modeled and rendered.
Thanks,
David

I uploaded my model but it doesn't show the entry

I also uploaded mine before the deadline but it hasn't shown up yet as an entry.

Hi everybody, we will not miss off any of the entries. Just have another look at http://grabcad.com/challenges/cydesign-part-6-honeywell-agt1500-engine/entries and send me an e-mail directly to kaspar@grabcad.com if your entry is not listed. Thanks.
David Hinz over 11 years ago
