Submission open until November 30, 2012

Description of Contest


Create the best 3D design in NCLab using PLaSM, NCLab‘s free web browser based CAD tool. Usage of PLaSM is very simple as you will find in this tutorial. The contest is not limited to the U.S. but the official language is English. PLaSM is a new addition to NCLab so all competitors have equal starting conditions. Once more - everything takes place directly in the web browser, no purchasing or installation of any software is needed. NOTE: This year's contest is closed. See the winning designs here.

Evaluation criteria

Evaluated will be the physical fidelity, complexity, and elaboration level of the design. A model of any existing 3D object such as a building, machine, car, train, plane, ship, etc. is acceptable. See bottom of page for sample project ideas.


First place: NCLab Full Version for one year (see details), an iPad 3, and Certificate of Award.

Second place: NCLab Full Version for one year (see details) and Certificate of Award.


The competition will close on November 30, 2012 and winning designs will be announced on 15 December 2012, and displayed on this web page along with their authors.


Every participant must be currently enrolled in a high school, middle school, elementary school, or equivalently home-schooled. Proof will be required. Participants who do not meet this eligibility criterion are welcome to submit their designs as well. The best design from this group will be awarded with NCLab Full Version for one year (see details) and Certificate of Award.


Registration will be open through September and October 2012. Every participant needs to register. Registration is done by sending an email titled „NCLab CAD Challenge 2012“ to events-at-nclab-dot-com.
