Concept matches the groups chosen theme? ISO, Top, Front, and Side Views completed? -3 Dark, clearly visible outer sketch Lines? Sketch has Lines Separating Lego Blocks? Each Custom Lego block includes a Multi-Section Solid -3 Feature and a Rib or Slot? 4 Custom Lego blocks identified with notes or balloons? (Mirrored parts count as one custom block) Enough detail to model the car? Concept name and Personal name on Sketch?

4 4 Concept Evaluation & Selection On Time? -5 Evaluation submitted as a PDF? Evaluation criteria derived from the proposal's feature list? Features given points and ordered by prioirity? Constraints identified and given yes/no evaluations? Concept names on Evaluation match the names on the Concept Sketches? Concept Evaluation compares only the top 4 Concepts? Any "Combination" concepts have a new sketch included clearly showing how the two previous concepts are combined. Ranking of concepts clearly indicated? Final Selection indicated? Appendix of 8 Concept Sketches attached in order of decending rank? (4 top sketches, then 4 sketches that weren't ranked)

6 6 CATIA Assembly - Chassis All parts present in a single folder? Submitted on Time? Is the Base component the best choice? Is the Base component fixed in an appropriate orientation? (one that mirrors real life) Does the Assembly order reflect the assembly order in real life? Does the subassembly structure reflect the subassembly structure in real life? Is the Assembly fully constrained? Do the constraints reflect the design intent? Are constraints or assembly features located in the proper Assembly/Subassembly? Are there no broken constraints? Are Assembly features used appropriately? Are External references used or not used appropriately? Assembly components don't clash or interfere with each other? 7 CATIA Model - Custom Block Potential Points Parts have been submitted with file names in the -40 format "UserName_PartName.CATPart" Block cannot be easily modeled using simple features? 0 Multi-Section Solid Feature present in the block? 0 Rib/Slot feature present in block? 0 Injection Moldable?
