How to Use This Document ►

Filling Out the Form

Work through modules in order, top to bottom. Each module has text fields, checklists, or image uploads. Textareas grow as you type. Complete all REQUIRED items before submitting.

Saving Your Work

The document auto-saves every 30 seconds to your browser. Click SAVE anytime. Closing and reopening in the same browser restores everything. The timestamp next to SAVE confirms the last save.

Download with Data

Click DOWNLOAD to export an HTML file with all responses and images embedded inside it. Opening the downloaded file restores everything. Use this to back up or transfer work.

Printing / PDF

Click PRINT / EXPORT PDF. A preflight check lists incomplete items first. In the print dialog, set destination to Save as PDF. Submit the PDF to Google Classroom.

Reference Panels

Gold i buttons open collapsible reference panels explaining draft, undercuts, parting lines, and SolidWorks steps. Screen-only — these do not appear in the PDF.

Rubric Panels

Each module header has a RUBRIC button showing grading criteria. The green dot on the right turns solid when all required fields in that module are complete.

Uploading Images

Click any upload zone, drag-drop image files onto it, or paste from clipboard. Multiple files at once is fine. Click any image for fullscreen view. Click REMOVE to delete.

Size Constraint Checker

In Module 04, enter your SolidWorks part bounding box X, Y, Z. The checker tells you instantly whether the part fits. Toggle IN / MM to match your SolidWorks units.

Background Interaction

Move your mouse to illuminate nearby grid intersections and leave a trail. Click empty space to fire a ripple. Hover over panels to see them glow. Hover over images and cards for lift effects.

MODULE 01

Part Concept

10 PTS

PTS	DESCRIPTOR
10	Part clearly named and described. Geometry communicated well enough for someone else to visualize.
7	Named but description vague.
4	Minimal. Form unclear.
0	Not submitted.

Decide what you want to mold. It can be anything — functional, decorative, abstract. No application required. Size is verified in Module 04.

PART NAME REQUIRED

DESCRIPTION REQUIRED

Describe the shape and main features clearly enough that someone else could picture it. (1–3 sentences)

0 / 1–3 sentences

MODULE 02

Hand Sketch

10 PTS

PTS	DESCRIPTOR
10	Sketch present, hand drawn, shows general form clearly enough as a modeling reference.
6	Present and hand drawn but ambiguous or doesn't match Module 01.
2	Digitally generated, printed, or traced.
0	Not submitted.

Get the idea onto paper before opening SolidWorks. No dimensions or annotations required — just the general shape. This is the only part of this assignment that must be done by hand.

SKETCH UPLOAD MIN 1 IMAGE

Drop, paste, or click to upload

0 images — minimum 1 required

CONFIRMATION

This sketch was drawn by hand — not generated, printed, or traced from any digital source

MODULE 03

Moldability Pre-Check

15 PTS

PTS	DESCRIPTOR
15	Draft direction clearly described. Min 2 features audited with risk assessed. Parting line described with geometric rationale.
10	Most fields complete. One vague.
5	Partial. Undercut table nearly empty.
0	Not submitted.

⚠ Complete this before opening SolidWorks. Every undercut caught here is free.

DRAFT DIRECTION REQUIRED

Draft is a slight taper on faces that run parallel to the pull direction so the part slides free cleanly. Without it the part grips the mold and tears on the way out.

Typical minimum: 1°–2° for smooth surfaces. The taper angles away from the parting surface in the pull direction.

Paper cup test: that taper letting cups stack is draft. Every face parallel to your pull direction needs it.

▶ VIDEO — What is Draft?

Which direction does the part pull out of the mold? Reference your sketch. (1–2 sentences)

0 / 1–2 sentences

UNDERCUT AUDIT REQUIRED — MIN 2 FEATURES

An undercut is any geometry that gets trapped by the mold when you pull the part free. In a two-part rigid mold an undercut makes clean ejection impossible.

Common culprits: holes perpendicular to the pull direction, recessed text on sidewalls, inward-facing lips or ledges.

Slide test: can you slide a piece of paper out in the pull direction without it catching? If it catches — undercut.

PARTING LINE RATIONALE REQUIRED

The parting line is where the two mold halves meet. Where you place it determines which features land on which half.

Best placement: at the widest cross-section, at a natural edge, on the least cosmetically critical surface.

The parting line is your mold's equator. Put it where splitting the part creates the least trouble on both halves.

Where does your mold split and why? (1–2 sentences)

MODULE 04

SolidWorks Model

15 PTS

PTS	DESCRIPTOR
15	Model views uploaded. Both draft analysis images present. Size check compliant. Nozzle limit acknowledged. File named. Confirmations checked.
10	One draft analysis missing, size non-compliant, or nozzle ack missing.
5	Single screenshot or file name missing.
0	Not submitted.

PRINT RESOLUTION — READ BEFORE MODELING The printers use 0.6mm nozzles. Combined with variable layer height in Bambu Studio, this sets the surface resolution of your printed mold.

Minimum feature size: 0.6mm (0.024 in). Any feature narrower than this — thin walls, fine ridges, sharp engraved lines, small holes — will not reproduce. They fuse shut, print as a blob, or disappear.

This is your one print attempt. There is no reprint.

NOZZLE LIMITATION ACKNOWLEDGMENT REQUIRED

I understand no single feature in my design may be less than 0.6mm (0.024 in) in width, and I have reviewed my model to confirm this constraint is met

PART SIZE CONSTRAINT CHECK REQUIRED

Bounding Box Verification

Evaluate tab → Measure, or Tools → Mass Properties → Bounding Box.

Max mold outer (tissue box): 9" × 4.5" × 3" | 228.6 × 114.3 × 76.2 mm
Max part: 8" × 3.5" × 2" | 203 × 89 × 51 mm

Enter all three dimensions to check compliance.

MODEL VIEWS MIN 2 IMAGES

Isometric + at least one standard orthographic view. Label each in the caption field.

Drop, paste, or click to upload

0 images — minimum 2 required

DRAFT ANALYSIS — BOTH PULL DIRECTIONS 2 SEPARATE IMAGES REQUIRED

1. Finish your part model.
2. Go to Tools → Draft Analysis.
3. Set Pull Direction to your parting surface. Screenshot — this is your top pull image.
4. Click the reverse arrow to flip direction. Screenshot — this is your bottom pull image.
5. Color coding: Green = positive draft | Red = negative draft (will stick) | Yellow = no draft.

Both images required. ▶ VIDEO — Draft Analysis

PULL FROM TOP — top mold half

Click to upload — pull direction: upward

0 images — 1 required

PULL FROM BOTTOM — bottom mold half

Click to upload — pull direction: downward

0 images — 1 required

SOLIDWORKS FILE NAME REQUIRED

CONFIRMATIONS

My part bounding box passes the size constraint check — result shows COMPLIANT

My SolidWorks model accurately represents the part described in Module 01 and visible in my sketch

ACADEMIC INTEGRITY DECLARATION

By submitting this assignment, I confirm that all written work and design decisions in this document are my own. AI tools may be used to support research, ideation, writing, and SolidWorks guidance. The hand sketch in Module 02 must be completed without AI.

AI USE NOTE — AI assistance is permitted and encouraged for all portions of this assignment except the hand sketch.
