Week 2 Computer-Aided Design

Step 01 — Setting up reference blueprints

Imported side and top view car sketches into Rhino using Picture. Scaled both images to real-world proportions and aligned them on the XY plane. Used centerlines and symmetry axes to ensure accurate proportions before modeling.

This stage helped me lock:

wheelbase

overall length

height

body proportions

This acts as the guide for all further modeling.

Step 02 — Creating primary profiles using curves

Traced the main silhouette using control point curves:

roof line

hood line

bumper

wheel arches

Then used: 👉 Extrude Curve

to give thickness and form simple 3D blocks.

This helped convert flat sketches into basic volumes and establish the car’s massing.

Goal here: Not detail — only proportions.

Step 03 — Building the base SubD cage

Created a closed outline of the car in top view using curves. Converted this into a SubD cage.

Used: 👉 SubD → ExtrudeSubD 👉 Insert Edge Loop

to create evenly spaced control loops.

This cage acts like a flexible wireframe that defines:

width

shoulder line

body thickness

At this stage the model is low-poly and easy to edit.
