Designing Real-World SolidWorks Assignments with Practical Engineering Workflow

Understanding the Nature of Practical SolidWorks Assignments

Many modern SolidWorks assignments involve:

• Modeling an existing mechanical part
• Preparing it for 3D printing
• Running basic or advanced simulation
• Choosing appropriate material
• Evaluating failure risks or performance
• Optimizing the design
• Exporting the file for manufacturing

This mirrors the structure of the attached example, where the designer digitally rebuilt a toilet-seat hinge bracket in SolidWorks and prepared it for Markforged additive manufacturing. On page 1, the author describes modeling the bracket directly in SOLIDWORKS and testing whether 3D-printed materials—like ABS versus Nylon White—would be strong enough.

Assignments like this teach you to think like an engineer:

• What forces will the part experience?
• What material is appropriate?
• How should the geometry be structured?
• Will a 3D-printed version function well?
• How do simulations guide the redesign?

If your SolidWorks assignment resembles the attached one, here’s how to approach it from start to finish.

Start With Reverse Engineering: Understanding the Existing Part

Before you ever touch SolidWorks, you need to understand:

• What the part does
• How it moves
• What loads it experiences
• How it assembles with other components

For example, the part shown in the uploaded document (Page 2) includes a looped hinge feature, a mounting base with screw holes, and a curved transitional geometry connecting them—clearly designed to accommodate rotational movement and distribute load.

To reverse-engineer a similar part, follow these steps:

Take accurate physical measurements

Use calipers, rulers, radius gauges, or even 3D scanning if available.

Measure:

• Overall length, width, and thickness
• Hole diameters and distances
• Radii of fillets and curves
• Functional features like hooks, slots, or hinges

Analyze mechanical behavior

Ask:

• Where does stress concentrate?
• Which features must be strongest?
• Which areas can be simplified?

For instance, in the attached assignment, the hinge bracket clearly experiences repeated impact loads from a toilet seat slamming shut—something the article calls out explicitly.

Identify constraints

• Connection points
• Mounting geometry
• Motion limits
• Clearances

This first phase sets the foundation for your SolidWorks model.

Rebuilding the Component in SolidWorks: A Step-By-Step Mental Model

Now that you understand the part’s requirements, the next step is to recreate it in SolidWorks.

The key is breaking the geometry into manageable features, not trying to draw everything at once.

Here’s a practical workflow used by experienced designers.

Step 1: Identify the Base Feature

Every SolidWorks model starts with a “base feature”—the simplest shape that most of the geometry will be derived from.

For hinge-type brackets:

• The base may be a rectangular or curved base plate.
• It could also be the cylindrical hinge block.

Choose the one that captures the "main mass" of the part.

Step 2: Sketch with Intent

Your sketches should be:

• Fully defined
• Centered using midlines
• Constrained with relations (horizontal, tangent, concentric, etc.)
• Parametric but not over-complicated

Students often jump into dimensioning too early. Instead:

1. Create a clean outline.
2. Add relations.
3. Dimension last.

Using images from the assignment (like the bracket visual on Page 2) as a reference helps you visualize how clean, symmetrically organized sketches aid modeling.

Step 3: Add Features Incrementally

Examples of incremental features include:

• Extrudes for bodies
• Fillets for stress reduction
• Cut-outs for holes and slots
• Revolves for hinge sections
• Lofted or swept features for transitions

The hinge bracket shown in the PDF clearly uses:

• A revolved or extruded circular hinge section
• A swept or lofted arm connecting the hinge to the base
• Cut-extrudes for screw mounting holes

Learning to identify these elements helps you reproduce similar parts.

Step 4: Use Reference Geometry

For complex shapes:

• Planes
• Axes
• Reference points

are essential.

They allow you to model off-center features accurately and manage symmetry.

Step 5: Apply Fillets at the Right Time

Fillets significantly affect:

• Stress distribution
• 3D printing quality
• Aesthetic and ergonomic properties

Apply them late in the modeling process unless they impact following features.

The hinge bracket example uses generous fillets for strength—something highlighted in the rendered images in the PDF.

Preparing the Model for Additive Manufacturing

Assignments like the toilet hinge bracket almost always include a manufacturing component—usually 3D printing.

This phase includes:

Choosing Material

The PDF compares:

• ABS (conventional)
• Nylon White (Markforged)

The author notes that Nylon White was strong enough for repeated impact loading—something the student must consider in any similar assignment. This insight appears on Page 1 when the material comparison is made.

In your assignment, you should:

• Review material strengths
• Consider layer adhesion
• Check deflection limits
• Evaluate environmental exposure (e.g., humidity for nylon)

Determining Print Orientation

Orientation affects:

• Strength
• Surface finish
• Support requirements
• Print time

You typically want:

• Holes oriented horizontally for better circularity
• Load-bearing features aligned with filament direction
• Fillets added to reduce stress concentration

Exporting the STL File

A standard workflow:

1. File → Save As → STL
2. Set resolution (Fine recommended for curved shapes)
3. Confirm unit accuracy

In the attached example, the STL is brought into Markforged Cloud Eiger software for print preparation, as shown on Page 2.

Running Simulations in SolidWorks

Simulation is where students often struggle—but also where assignments like this shine.

The PDF mentions that once the part was modeled, the author ran a SOLIDWORKS Simulation to evaluate material performance.

You can follow the same process for any similar assignment:

Step 1: Apply Material

Choose material properties from the library, or add custom ones for 3D printing.

Step 2: Set Constraints

Typical bracket constraints include:

• Fixed faces at screw holes
• Load applied at the hinge or connecting arm

Step 3: Add Loads

Loads could be:

• Static force
• Impact force
• Pressure
• Bearing load
• Moment

In a toilet-seat hinge assignment, for example, the load simulates someone sitting or the seat slamming (which the PDF humorously references).

Step 4: Mesh the Model

Use finer mesh in:

• Fillets
• Thin features
• High-stress zones

Step 5: Run and Interpret Results

Focus on:

• Factor of safety
• Maximum stress
• Displacement
• Potential failure areas

Assignments often require you to redesign if simulation shows excessive stress.

In the PDF, the designer explored multiple materials before deciding Nylon White was strong enough—demonstrating an iterative process students should emulate.

Iterating and Improving the Design

Real-world engineering is iterative.

After initial modeling and simulation:

• Review weak points
• Increase fillet radius
• Add ribs
• Change material
• Modify wall thickness
• Adjust hole placement

The uploaded assignment shows how simplifying the simulation assumptions accelerated the redesign process. The article explicitly notes that even with simplified simulations, the worst-case scenario was a quick reprint. This highlights a lesson: assignments encourage learning through iteration, not perfection.

Documenting Your Work for Submission

SolidWorks assignments require more than a model—professors want engineering reasoning.

Your submission should include:

• Problem description
• Measurements and sketches
• Modeling strategy
• Material selection explanation
• Simulation setup and results
• Optimized final design
• STL preparation and printing considerations
• Reflection on challenges

Use screenshots of:

• Feature tree
• Sketches
• Simulation vectors
• Stress results
• Manufactured prototype (if printed)

Common Student Mistakes—and How to Avoid Them

After helping thousands of students with SolidWorks assignments, we see recurring issues:

• Starting modeling without analyzing the part

Always inspect geometry first.

• Over-complicating sketches

Keep sketches simple—let features do the work.

• Applying fillets too early

Apply them when major geometry is complete.

• Skipping simulation or misinterpreting results

Simulations exist to validate design decisions.

• Choosing the wrong 3D printing orientation

Orientation can make or break mechanical strength.

• Rushing the STL export

Ensure accuracy and correct tolerances.

The uploaded example shows careful material comparison, simulation insight, and real-world validation—habits every student must learn.
