Design Automation
Project Details
In this project, I utilized the API of CAD software to design an automated storage tank model. Inputs, such as tank diameter and capacity, are collected through a form. The model generates general arrangement and fabrication drawings, which include a Bill of Materials. Automating the design process by programming it in API saves time and reduces the risk of errors. The final step involves making any necessary modifications to the generated drawings.
Project Objectives
CAD modelling of a Storage Tank
Design automation using API with the user interface.
Automated drawing and BOM generation.
Vehicle Chassis Redesigning
Vehicle Chassis Redesigning
Project Details
I participated in an R&D project where I redesigned vehicle chassis. The goal was to determine the most feasible chassis to manufacture in-house. Chassis material and design were tested in the lab and the manufacturing process was determined. Probable costs were calculated through consultation with in-house manufacturing departments and workshops.
Project Objectives
Chassis material composition testing
Redesigning chassis and CAD Modeling
Design Automation using API
Manufacturing process determination
Manufacturing cost estimation
CAD Model of Light Commercial Vehicle Chassis
CAD Model of Pickup Van Chassis
CAD Model of Three Wheeler Chassis
