INTRODUCTION & ABOUT ME

Introduction:Hello there! My name is Karan Shah and I am a Mechanical Engineer, currently working as a Research Assistant at Arizona State University. ThisCAD Portfolio is created to supplement my resume that allows me to showcase the CAD Skills I have gained and developed over the course of myeducational and professional career. I have recently graduated with a Master’s degree in Mechanical Engineering from Arizona State University.Now, I stand on the threshold of my professional career holding a Masters degree looking forward to building a challenging and successful careeras Product Design Engineer/ Product Development Engineer/ Mechanical Engineer that can take me to the frontiers in the fascinating field ofmechanical engineering.

About Me:Product design is my passion and CAD modeling is my strength. I am proficient with multiple CAD packages as described in my resume and I caneasily make a transition from one package to another based on the requirement. I consider myself to be a creative individual capable ofvisualizing a conceptual idea and converting the same into a perceptible 3D model. Not to forget, I have self-learned surface modeling usingSolidworks only to satiate my love for designing cars.

Online Portfolios:I have showcased my CAD models via GrabCAD online 3D viewer and engineering skills through a digital portfolio that also supplements myresume and extensively describes each project that I have completed throughout my engineering education. These can be reached by followingthe links provided below.

CHEVROLET CAMARO – SURFACE MODELING

Overview:The body panels of Chevrolet Camaro have been modeled using SolidWorks based on the following blueprint sketches. The body panels havebeen developed using surface modelling tools like compound splines, projected curves, surface loft, boundary and filled surfaces, surface trimand indent tool. This project is completed based on my personal interest of 3D modelling of cars.

LAPPING MACHINE

17

Overview:Lapping Machine is used to carry out the lapping process to obtain surface finish by material removal when pressed against each other in the presence of an abrasive. I have completed this model of the Lapping Machine as a part of my work as a Research Assistant at Arizona State University. 3D Model is generated based on rough 2D drawings obtained from hand measurement.

DESIGN OF A HOME APPLIANCE - LAWNMOWER

Overview:The aim of this team project was to design a home appliance that consists of at least one primary rotating component. The following images attached demonstrates the CAD model of the Lawnmower and the components and their respective sub-assemblies like the battery system, engine system and the fuel system together forming the power system that I have designed. The other sub-assemblies like the cutting deck, chassis, hydraulic system and lifting mechanism have also been displayed but they have been designed by my other team members.

Overview:The objective of this project was to design a creature capable of three worldly interactions. I choose a Pegasus as the creature which iscapable of flapping its wings, walking and nodding its head as the three worldly interactions. A final design was to be designed representingthe skin of the creature and the assembly of the three selected mechanisms for the interactions with fasteners and standard parts like gears,motors and linkages. The final design should be easily placed inside a box of 0.5 x 0.5 x 0.5 meters.
