CAD Engineers: Parametric Modeling and Modification Tasks
About this role
What We're Researching
We're running a paid study on parametric design practices and mechanical engineering workflows.
This project focuses on how professional designers construct 3D assemblies and plan for future modifications.
Your contributions will help us evaluate industry-standard approaches to feature trees and design history management.
How It Works
You will be tasked with creating realistic parametric CAD models from scratch based on specific engineering requirements.
After completing the initial geometry, you will document and execute a series of structural modification tasks on your own design.
While you can draw on experience from various modeling environments, all final submissions must be delivered as native, editable SolidWorks files.
We expect you to maintain a clean feature tree that clearly demonstrates your design intent and revision history.
Who This Is For
We are looking for mechanical engineers, product designers, and CAD specialists with strong 3D modeling fundamentals.
We welcome professionals with backgrounds in SolidWorks, NX, Fusion 360, or other major parametric design software.
You must have the ability to generate clean, native SolidWorks files with an intact design history for your final deliverables.
What You'll Do
Create complex parametric CAD models based on realistic engineering scenarios
Design and execute structural modification tasks on your initial geometry
Maintain a logical feature tree that preserves full design history
Export and submit all final deliverables as native SolidWorks files
Who Should Apply
Professional experience in mechanical engineering or industrial design
Strong proficiency with 3D parametric modeling software (SolidWorks, NX, Fusion 360)
Ability to produce native, fully editable SolidWorks assemblies
Comfortable building models that anticipate future structural modifications
Compensation
$200 per task
