Show off your skills and solve real design problems
CyDesign challenges you to create CAD models of a passenger car.
CyDesign Labs is building a detailed physics based modeling and simulation environment and seeks
great looking components to populate a library of components to use in this simulated environment.
CyDesign Labs is in need of CAD surface models of different components that would be part of a car.
The challenge is that the final designs must not replicate existing, trademark and copyright protected
components, and must be an entire set of components.
Given a list of basic automobile components, a set of basic images and basic specs (see below), can you
produce a set of surface models that are rendered into small, 3D CAD visual files? If so, cash is in your
skills.
Submitted entries for each set must include models of each components listed in that specific set; entries which do not have the requested 3D CAD visuals and models for each component of the set will not be considered.
Each set has five different models to be provided. Four sets have the same type (wheels/tires, engines, transmissions, brakes, suspensions); one set has multiple types (set 5).
The following car components must be modeled and rendered:
SET 1
Wheel and Tire Combinations (one model and visual rendering of each, 5 total as a set)
• High Performance Racing Tire with Aluminum Wheel - 245/40 16 tire size
• High Performance, Studded Racing Tire with Steel Wheel - 17 in, steel wheel, P245/65R17 tire size.
• Wagon Wheel with metal rim - R17 “wheel/tire size”.
• Common Passenger Tire/Wheel - 17-in. 5-spoke alloy wheels with P215/45R17 tire size.
• Common Bicycle Tire/Wheel - ISO 559 mm, 26x1.0 in to 26x2.5 in, found on most modern mountain bikes.
SET 2
Engines (one model and visual rendering of each engine, 5 total as a set)
• Front mount, Inline 6 Gasoline Engine, approximately 3 liter displacement.
• Front mount, Inline 6 Gasoline Engine with Turbocharger, approximately 2.5 liter
displacement.
• Front Mount, Hybrid (I4 + Electric Motor)

SET 4
Transmissions (one model and visual rendering of each transmission, 5 total as a set)
• Typical transmission found in Group B Rally car: 5-speed manual, AP twin plate
paddle clutch with cerrametallic linings.
• Typical transmission:5-speed manual, mid size, 4 door, passenger car size.
• Typical transmission: 7-speed automatic, mid size, 4 door, SUV vehicle size.
• CVT, compact car, 4 door, passenger car size.
• Bulldozer transmission, capable of having: a) Planetary gear and multiple-disc clutch with hydraulically actuated and forced lubrication, with 3 forward and 3 reverse speeds.
SET 5
Other Car Components (5 total components as a set)
• Auto Body Frame, typical of those found in Group B Rally Cars
• Transaxles (one model and visual rendering of each)
- 4 wheel drive (aka AWD), typical of those found in Group B Rally Cars
- 2 wheel drive
• Typical Rally Car Suspension (one model and visual rendering of each):
- Front: independent, double wishbones, twin coil springs and telescopic
dampers, anti-roll bar.
- Rear: independent, double wishbones, twin coil springs
dampers, anti-roll bar, adjustable toe control link.
Each component in the set should be rendered into an individual 3D Graphic image size of approximately 256 pixels by 256 pixels size; submitted file sizes much larger will not be considered.
Each component model can be done in any CAD software, but entries must be submitted as a STEP, .obj, and .png file type for each component in the set. Entries without each file type for each component in the set will not be considered.
The 3D CAD models for each component in each set should have:
• Only external surfaces modeled and rendered; no internal surfaces/components needed/required.
• Mono-chromatic coloring with minimal shading required; do not need complex, multi-light source shading.
• 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.
• Each component in the set that is visualized must not replicate existing or previously produced, recognizable, components which are trademark and/or copyright protected by their respective owners.
The competition is open to everyone; public entries only.
One engineer can submit several entries, but no more than one will win a prize.
Tag your rendered set with “Car Component Challenge” when uploading it to GrabCAD to make it easier to find.
Each component in the set should be rendered into an individual 3D Graphic image size of approximately 256 k pixels by 256 k pixels size; submitted file sizes much larger will not be considered.
Each component model can be done in any CAD software, but entries must be submitted as a STEP, .obj, and .png file type for each component in the set. Entries without each file type for each component in the set will not be considered.
Only models uploaded to GrabCAD library will participate in the competition.
Only models uploaded through this challenge page here will participate in the competition.
The competition ends 10/29/12.
The contest sponsor has the right to use the winning entry for marketing purposes and becomes owner of the winning design.
$1,000 cash + CyDesign Labs T-Shirt (L or XL) for most realistic, best looking 3D CAD models of components provided for each set. 5 distinct sets are listed for creation, so 5 first prize awards will be given.
2nd Prize: $500 cash + CyDesign Labs T-Shirt (L or XL). 5 distinct sets are listed for creation, so 5 second prize awards will be given.
Submissions will be judged upon timeliness of submittal, accuracy of 3D models relative to the requirements and rules noted above.
The judges will be comprised of CyDesign and GrabCAD staff.
CyDesign Labs is developing a physics-based modeling system that will let engineers quickly assess design options and continuously test against requirements during the early design phase. Should the vehicle have conventional or hybrid drive? How will thermal loads affect an implanted medical device? Providing answers to these questions early in the design results in a more robust and reliable system.
CyDesign Studio, the flagship product, is a the only model-based design optimization platform with integrated requirements management that enables organizations to design complex systems with better, faster results.

What does 256k by 256k mean? I hope its not 256000x256000 pixels...
Romano Gaspari over 11 years ago
does high performance tire mean slick one?
marcos over 11 years ago
i dont really get what we have to do .... do we have to model all that parts ? or just a set ? or just one part of each set ?
David Hinz over 11 years ago
Comed,
it is supposed to be "256 x 256 pixels". the "k" is not supposed to be there and will be removed.
David Hinz over 11 years ago
marcos,
we are asking for submittals by set. so, a person can just model one particular set (ex: the wheel/tires) and submitted the set (5 models) for the challenge.
a person (or team) could also decide to model multiple sets and thus compete for multiple parts of the challenge.
remember, though, each set is comprised of 5 models each.
hope that helps.
Romano Gaspari over 11 years ago
how many mounting hole wheels must have got?
375Designs over 11 years ago
Modelling 5 engines in 17 days!! It took me 3 months to model one :p
teigan over 11 years ago
these contests specs are getting more and more tedious to read through.
CCG over 11 years ago
No offence but this is not a contest...this is hard work for nothing....i wish i had money to make my company...and then put challenges to grabcad so it would result a great design paid with low price and high profit for me.Good luck with this gent's.
Ibrahim Sanih Ahmed over 11 years ago
mmmh... haha... i was going to write up a few questions regarding the reqs. but then i saw the deadline!!! hehehe... talk about rushing something...
Romano Gaspari over 11 years ago
once again: how many mounting holes for the wheels and the disc brake? there is no support for this challenge and the requirements aren't clear enough!
David Hinz over 11 years ago
Romano: Please use 5 hole designs for the wheels; high performance tire should have some tread; no slicks, as those will not work in environments where the road suface is not super smooth.
All,
Please note, the visual size is 256 x 256 pixels; the requirement of 256 k x 256 k is wrong and will be changed ASAP.
Romano Gaspari over 11 years ago
the same 5 holes for the break discs?
David Hinz over 11 years ago
Hi Romano, You bet, the same 5 holes for the disc brake components as well would be great. Thanks for asking specific questions and participating in our challenge.
David Hinz over 11 years ago
Marcos, apologize for the delayed response, but wow, nice wagon wheel!
Yes, each of the 4 sets has a crazy component (wagon wheel, lawn mower engine, mountain bike disc brake, bulldozer transmission).
Variety is key for our component library, so having a crazy component helps to illuminate that capability of our product.
john over 11 years ago
is there always gonna be a winner in these contests? or if the customer doesnt like any , maybe nobody wins..? yes or no?
Jordan Waite over 11 years ago
why can't i upload my designs?
David Hinz over 11 years ago
Marko Lukac - nice set of rims, but remember, the set to be created as a valid submittal needs to all of the items listed, and the wheels should include tires:
SET 1
Wheel and Tire Combinations (one model and visual rendering of each, 5 total as a set)
• High Performance Racing Tire with Aluminum Wheel - 245/40 16 tire size
• High Performance, Studded Racing Tire with Steel Wheel - 17 in, steel wheel, P245/65R17 tire size.
• Wagon Wheel with metal rim - R17 “wheel/tire size”.
• Common Passenger Tire/Wheel - 17-in. 5-spoke alloy wheels with P215/45R17 tire size.
• Common Bicycle Tire/Wheel - ISO 559 mm, 26x1.0 in to 26x2.5 in, found on most modern mountain bikes.
Keep the entries coming!
David Hinz over 11 years ago
John,
I am confident the GrabCAD community will provide designs and submittals that meet our requirements and be compelling enough to determine a winner for each set requested.
Grant Thomas-Lepore over 11 years ago
@Jordan Waite - please let me know more about your issue. You can PM me directly. Thanks!
Om Prakash Yadav over 11 years ago
regarding SET3: What do you mean by disk brake; 1: will i need to model disk brake rotor and caliper both or just rotor? 2:can you please provide more info like maximum speed at which brake will be applied and the caliper piston capabilty(max pressure applied) for my design calculations.
Romano Gaspari over 11 years ago
guys, please, upload all your models requested for a set as a single entry
Santoo over 11 years ago
what is the procedure for a group entry? am new to it.... please explain. Would be glad, if it is a bit detail....
grabacada over 11 years ago
It is given to upload file as a .obj. Is it not enough if it is in STEP file?
Tomas over 11 years ago
David Hinz: wagon wheel - how should they look like? Like this (example) http://www.silverfoxsalvage.com/product_info.php?cPath=22&products_id=29
or like this (example) http://www.etsy.com/listing/60693461/antique-steel-iron-wagon-wheels-with ? Thank You! :)
Tomas over 11 years ago
...or like this (example) http://en.wikipedia.org/wiki/File:GWR_Spoked_wagon_wheels.jpg
Thank You!
David Hinz over 11 years ago
Feedback and questions addressed:
Tomas - like the direction you are going for the SET 1 entry - all the wheels/tire combo's across the different formats.
Santoo- 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.
David Hinz over 11 years ago
Tomas,
To your question on wagon wheels, we prefer wood wheels with metal rims, similar to your first link. For vehicle modeling purposes, it allows our mechanical engineers the ability to construct a complex model of a wood structure with a metal rim, vs. an all metal design.
David Hinz over 11 years ago
Om Prakash Yadav
A disc brake with rotor would be great. see http://www.expertcarcare.com/maintenance-guide/brake-system. some folks only have the actual pads, which are useful as well. we will be looking at the entire set as well as individual parts.
Size of vehicle?
850kg to 960kg would be a typical weight.
David Hinz over 11 years ago
Jordon, Garrett, Your entries are also looking nice!
Garrett Taylor over 11 years ago
This is probably going to take me longer than the remaining time for this challenge...
Tomas over 11 years ago
David Hinz, how should look passenger car hand brake? Need all parts, like rotor, caliper, ...? Maybe some link to picture?
Thank You!
Carlos Paredes over 11 years ago
Can I use CyDesign logo?
David Hinz over 11 years ago
Hi Carlos, No need to use the CyDesign logo for this challenge.
David Hinz over 11 years ago
hi Tomas, here is a picture of a car hand brake, no need for the rotors and calipers associated with it...
http://en.wikipedia.org/wiki/Parking_brake
David Hinz over 11 years ago
Hello GrabCAD community, excellent wheels+tires and brake entries. Anyone planning to supply engines, transmissions or the other set of components? Let me know if you have any questions regarding those three sets.
Garrett Taylor over 11 years ago
I would, except that there are only 4 days left and I don't know where to get enough information to build the parts of any of those sets.
Carlos Paredes over 11 years ago
I want to do also Set 4 or 5 but, do you have any reference pictures?
Ármin Fendrik over 11 years ago
Yes, some reference pictures would be great, especially in connection with set2 (the motors), becouse Im not sure, how I should model them (with the plastic coverings, or withuout the, etc.
Romano Gaspari over 11 years ago
I have difficult in traslating vacuum servo in Italian... can anybody help me?
Garrett Taylor over 11 years ago
it's an electric brake booster...like ABS maybe? http://en.wikipedia.org/wiki/File:Servofreno_seccionado.jpg
David Hinz over 11 years ago
Here is a GrabCAD example of a lawn mower engine which is appropriate:
Briggs & Stratton 10 HP OHV
David Hinz over 11 years ago
Here are a few examples of engines which have the appropriate level of detail:
Renk transmission hswl 194
Cummins VT-903-M
Detroit Diesel Engine 13

David Hinz over 11 years ago
Comed,
See the GrabCAD examples to provide some direction.
David Hinz over 11 years ago
i added a wireframe of how the actual component renderings and models will be used, if that helps everyone understand the usages.
See here:
Example of how the component models will be used.
Ármin Fendrik over 11 years ago
Thank you David, this helps me a lot.
Tomas over 11 years ago
Thank You David for examples.

Is there a delay in the upload time? I upload my entry a few minutes ago but its not showing up?
Ármin Fendrik over 11 years ago
Im looking for a team for SET2. Im ready with the motor of the lawn mover, and now working on the Front mount, Inline 6 Gasoline Engine, approximately 3 liter displacement. If someone is interested, please contact me.
David Hinz over 11 years ago
Romano, our logo assets can be found here: http://grabcad.com/challenges/cydesign-labs-group-b-rally-car-challenge - go to the "download the spec" button.
David Hinz over 11 years ago
Christian, i see your entries. Not sure of the time lag/delay, but they are there now.

Pawel Stateczny over 11 years ago
My set is still not visible here, I dont know why. Any idea? It is visible on my profile though...
David Hinz over 11 years ago
Marko Lukac, your bike tire looks to be missing a wheel.
David Hinz over 11 years ago
Pawel, Contact GrabCAD support at http://grabcad.com/questions
Pawel Stateczny over 11 years ago
I have contacted everybody here and still no solution...

CyDesign Car Component Challenge, Set 3
Rob Podell over 11 years ago
Please add that. ^
Christian Padilla over 11 years ago
@Rob Podell - I had luck by clicking the link on THIS page. Its blue and says submit an entry. you upload one part file, a .step worked for me, and then name it, tag it, and click upload. Then your submission should show up on the list and you can upload more files to it later
Christian Padilla over 11 years ago
@omega @PawelStatczny ^^^^^^ see above
Arfi'an over 11 years ago
I've submitted My Model 4 hours ago, but till now still did not appear :-(

omega over 11 years ago
ich submitted my part set (car-component-challenge-4) 9 hours ago and its still not showing up
Ármin Fendrik over 11 years ago
I think its just some bug, hopefully it will be corrected.
Jordan Waite over 11 years ago
did you type in car components challenge into the tag box?
cause if you did that's why it's not showing up.
Ármin Fendrik over 11 years ago
Yes, I typed it, but now I will remove the basic tag, if that helps.
Ármin Fendrik over 11 years ago
No, it did not help.
Romano Gaspari over 11 years ago
my set doesn't appear too. I sent message to @kaspar Kiis with file link. do the same
Ármin Fendrik over 11 years ago
Kaspar cant be reached till 5th of november. (according to the e-mail)
Romano Gaspari over 11 years ago
so how we do tu submit files in challenge?
Rob Podell over 11 years ago
What email address are we supposed to contact? My set is not showing up!
Rob Podell over 11 years ago
Christian, I did that. It just never showed up.
Romano Gaspari over 11 years ago
I ve great problems... uploader doesn't work fine... missing files
Romano Gaspari over 11 years ago
finally it showed up in the entries list but uploader error again
omega over 11 years ago
@ Romano, my set is still not showing up, how dit you get it working?
Arfi'an over 11 years ago
Still did not appear :-(
Ármin Fendrik over 11 years ago
Mine neither. Its not really good :(
Romano Gaspari over 11 years ago
@omega I did some modifications to tags and after a number of changing finally the system include my entry. the problem still is with the uploader... I ve tried to upload one step file and .obj for a lot of times... uploader stopped at half way.
omega over 11 years ago
@romano did you actually managed to get hold on someone in charged for this? i did not and i am quite indignant about it.
Sara Sigel over 11 years ago
Please email me at sara@grabcad.com if your entry is still not visible. I'm sorry that we did not see this earlier, but will make sure everyone gets their entry in the challenge. If you already sent an email to info@grabcad.com, I will reply to you through that as well.
omega over 11 years ago
perfect, thanks a lot!
Romano Gaspari over 11 years ago
@omega yes I had sent message to kaspar before challenge ending but I think he was not at work so I did it by myself making attenction to tag words
Sara Sigel over 11 years ago
Yes, like @Romano says try adding the correct tags, "Car" "Component" "Challenge."
omega over 11 years ago
ok tags are set, hope it does the difference
omega over 11 years ago
still not visible, frustrating
omega over 11 years ago
@sara, got your mail. thanks :)
Romano Gaspari over 11 years ago
@omega don't be frustrated... I told you to check your tags and I did it for you.... correct tag is components not component. change it
Jordan Waite over 11 years ago
when do we find out the results?
Romano Gaspari over 11 years ago
I think never cause few entries :(
Srdjan Bjeljac over 11 years ago
I have one question...Can I put rendered picture of sparkle afterward in contest??? And how??
Christian Padilla over 11 years ago
Will results be available anytime soon?
maheshkumar over 11 years ago
when the CyDesign Labs Passenger Car Components Challenge results?
Ármin Fendrik over 11 years ago
The average time as I noticed till the results come is about 1 month. But Im not sure about it...
Christian Padilla over 11 years ago
I wish an admin *cough cough* would let us know :D
Sara Sigel over 11 years ago
The results take about a month. Stay tuned!
Christian Padilla over 11 years ago
Thanks Sara!
Romano Gaspari over 11 years ago
why so long time for just few valid entries?
Garrett Taylor over 11 years ago
i know right
Romano Gaspari over 11 years ago
@Christian Padilla you had no projects before competition and no grabcad community activities... why something is telling me you'll be the winner?
Christian Padilla over 11 years ago
@RomanoGaspari Haha, thanks for the vote of confidence, I appreciate it! I just heard of grab cad a few weeks ago and I loved the concept. I hope to participate in a good number of activities in the future, but everyone has to start somewhere right? Either way, there a few other good entries, I'm just going to keep my fingers crossed.
Garrett Taylor over 11 years ago
Congrats Tomas, but I thought you could only win once. Rule #2: "One engineer can submit several entries, but no more than one will win a prizev"
Arfi'an over 11 years ago
I just deleted My entry because I saw that the Jury choose the winner in a good way, but They ignored some rules (although They make those rules). Congratulations and good luck to all winner. For GrabCAD and Someone (or company or organization) which running a future challenge in GrabCAD, hopefully They respect to all the entries with respecting the rules. Good Luck everyone !!!
Sara Sigel over 11 years ago
@Garrett and to all participants. We just noticed this and we'll get some more clarification from CyDesigns. Obviously we should follow all rules and requirements - fairness first. Please be patient and send me a private message if you have any concerns or questions. I will be sure have your feedback heard by all.
Sara Sigel over 11 years ago
@Arfi'an I will contact you via private message and hope you will reconsider.
Sara Sigel over 11 years ago
Thank you to our community! You pointed out a mistake in the results and we have corrected our error. We apologize, a winner can take home only one prize in any challenge. For that reason @Tomas will no longer be the 2nd place winner of Set 3. We talked it over with him and apologized. There is a silver lining in this mistake. Now, we have a new winner to celebrate! Please congratulate @Garret Taylor for getting the second prize on Set 3. Thank you again for letting us know and for being patient while we straightened things out.
Rob Podell over 11 years ago
Did anybody receive their prize money yet?
Garrett Taylor over 11 years ago
Nope, a And Amy Kozlowskv said she was sending the funds to me over a week ago.
Garrett Taylor over 11 years ago
I just recieved my prize money today! Thanks GrabCAD!
Sara Sigel over 11 years ago
Great @Garrett! Anyone who needs help with this can contact me, sara@grabcad.com.
