ASTROCAD ASSEMBLY CHALLENGE
Parallel CAD modelling, space mechanism assembly & kinematic validation.
Kumaraguru SEDS conducts the AstroCAD Assembly Challenge 2026 on 15 October 2026 as a half-day, offline engineering competition. The event tests parallel CAD modelling, design interpretation, assembly discipline, and teamwork through one common space-component assembly problem. Each team consists of two members using separate laptops. Member 1 models Parts A, B, and C, while Member 2 models Parts D, E, and F. After completing the assigned parts, both members collaborate to produce a fully constrained, interference-free final assembly that demonstrates prescribed motion under strict engineering tolerances.
ABOUT THE EVENT
The competition is designed around a realistic engineering workflow in which a larger space product is divided into individually owned components and later integrated. This makes the challenge more substantial than a single-part speed-modelling contest while remaining feasible within a half-day schedule.
Using one common verified reference package ensures that all teams face the same technical difficulty and can be evaluated through a consistent marking scheme.
Permitted Software: Any approved parametric CAD software capable of native parts, assemblies, and neutral STEP export (e.g. SolidWorks, Autodesk Fusion 360, PTC Creo, Siemens NX, Onshape, CATIA). Both teammates should use compatible versions.
COMPETITION DOMAINS & WORKFLOW
RULES & REGULATIONS
- RULE 01 Eligibility & Equipment: Two-member teams. Each member must bring a separate laptop, charger, and approved CAD software installed before reporting.
- RULE 02 Part Ownership: Member 1 must model Parts A, B, and C. Member 2 must model Parts D, E, and F. Reassigning a principal part before assembly is prohibited.
- RULE 03 Collaboration & Assembly: Teammates may discuss dimensions and interfaces throughout the event. After parts are complete, both members collaborate on assembly integration, constraints, and interference correction.
- RULE 04 No External Geometry: Internet access, generative AI, pre-built models, external libraries, and reuse of previous CAD files are strictly prohibited. All geometry must be created on-site.
- RULE 05 Submission Deliverables: Six native part files (A–F), one native assembly file, one neutral STEP export, exploded view, interference verification screenshot, and short motion demonstration.
