TECHNICAL DRAWINGS Universities with SolidWorks Education typically provide students with the license to download & use SolidWorks on their personal devices.

Check with the relevant tutor.

Minimum Specs Required

Check out the following online resources and guides: from 3D Hubs: Injection Molding Guide CNC Machining Guide CNC Cost Reduction Tips 3D Printing Guide Also look at Jaycon-Systems’ Engineering Guidelines to Designing Plastic Parts for Injection Molding & the Mold Design Tips for Manufacturing.

You can generate 2D drawings in SolidWorks from the 3D solid parts and assemblies you design.

There are several benefits to this; it is more efficient than manually drawing; you can review 3D models and check issues with geometry and design prior to generating drawings; you can automatically insert dimensions and sketches from the model sketches and features; and if you were to update your part models or assemblies, this will be reflected in the drawing documents (parts, assemblies, and drawings are linked documents; any changes that you make to the part or assembly changes the drawing document).

Whilst this section has been compiled to benefit students using SolidWorks, certain links & resources can also be utilised by those using other CAD packages.

WHERE TO START: Check out the SolidWorks help page for SOLIDWORKS Detailing & Drawing, which gives an overview and explanation of the concepts and techniques. You can refer to the SolidWorks Introduction Guide pp.69-85 & pp.119-121.

Also refer to the online primer: Introduction to Engineering Drawing: Projections & How to Dimension.

SELECTED TUTORIALS: We have listed a selection of video tutorials to help you refresh and review technical drawings.

Remember to access LinkedIn Learning - FREE to students whose institutions have signed up. Here you might want to check out the following short courses for SolidWorks Drawing: Sections 15-18 of SW 2019 Essential Training & Section 2 of The Cert Prep: Drawing Tools, both by Gabriel Corbett, who also has really useful LinkedIn Learning videos pertaining to SolidWorks. Also see SOLIDWORKS: Drawings by David Antanavige.

Whilst creating your technical drawings, remember these must adhere to the BS 8888 standards; the UK standard for engineering drawings and geometrical tolerancing. These cover the requirements for the technical specification of products and their component parts. The current, 2017 edition includes the international standards you need to prepare a proper technical product specification. Check the BSI website for an overview on the standards and scan through the ‘BS 8888 pdf’ online.

DfMA Design for Manufacture (DfM) relates to the design for ease of manufacture of the parts that will form a product, and Design for Assembly (DfA) relates to the design of the product for ease of assembly. DfMA relates to both of these working together towards enhancing efficiency, reducing costs and errors.

Check out the following lecture for a refresh / introduction: What is Design for Manufacture & Assembly Peruse the General Principles of Design for Manufacture and Assembly slides by San José State University alongside the Design for Manufacture (10) Guidelines (2 pages).

Rolls-Royce also have a PDF on How to Design for Manufacture and Assembly.

Likewise, there are numerous articles & papers on the development and history of DFM, DFA and related topics in today’s manufacturing systems. Search away... :)

SIMULATIONS & ANIMATIONS

SOLIDWORKS SIMULATION SolidWorks has a simulation system, which allows you to do the design analysis of the 3D model; including linear and nonlinear static, frequency, buckling, thermal, fatigue, pressure vessel, drop test, linear and nonlinear dynamic, and optimization analyses. “ SolidWorks uses the Finite Element Method (FEM). This is a numerical technique for analysing engineering designs. FEM divides the model into many small pieces of simple shapes called elements effectively replacing a complex problem by many simple problems that need to be solved simultaneously. Analysis using FEM is called Finite Element ” Analysis (FEA).

SIMULATIONS & SOLIDWORKS: Check out the publication by J.Ed Akin of Rice University, Texas, USA titled “Finite Element Analysis Concepts via SolidWorks.”

This is aimed for beginners who want to utilise FEA techniques but have not studied the theory.

The book is based on the author’s “forty years of teaching finite element analysis, applying it in consulting applications and programming FEA.”

Setup and Study of Load Steel Structure Simulation Static Simulation: Analysing Impact of Adding Ribs in Design of a Plastic Stool Non-Linear Stress Analysis Weldments & Frame Stress Analysis Thermal Study Introduction Steady State/Transient Thermal Study SolidWorks Flow Analysis for Beginners

WHERE TO START: Check out the SolidWorks help page for SOLIDWORKS Simulation & SimulationXpress, which gives an overview and explanation of the simulation concepts alongside step by step guidance + the SW lessons.

ANIMATIONS Like CAD, there are many programs that will facilitate animation; including 3ds Max, Catia, Blender, KeyShot and SolidWorks. Some of these can be combined i.e modelling in SolidWorks; animating in 3ds Max; and rendering in KeyShot.

Autodesk have over 100 products available for free for students, including 3ds Max. Download your Educational License.

FREE SOFTWARE

After building your 3D model, you can test the efficiency of its performance by using analysis tools. This allows you to simulate testing of the 3D model without spending lots of time and resources in the field; allows you to refine, improve and optimise designs by testing concepts and scenarios during design and development; and can therefore also reduce the number of product development cycles.

There are no limits to what you can do with animations; from 360º rotations, to assemblies, and exploded views. Here we present publications, playlists & short courses to get you started.

Check out the Autodesk’s guide on the fundamentals of creating animation with 3ds Max - explaining basic animation processes in 3ds Max. And on LinkedIn Learning watch Section 5. on Learning 3DS Max; Section 14 in 3ds Max 2019 Essential Training; Section 5.

RENDERING & VISUALISATIONS There are many rendering programs. One of the most popular in your discipline is KeyShot. You also have Cinema4D, 3ds Max, Blender, Fusion 360 & not forgetting the ability to render on SolidWorks.

Feel free to try the various versions to see which one you find to be best for the desired application. Each program and software has its individual benefits! And at times you can even combine them.

KEYSHOT “ KeyShot is a stand-alone, real-time ray tracing and global illumination program used to create 3D renderings, animations and interactive visuals. With its CPU-based architecture, photorealistic real-time rendering can be achieved on both Mac & PC. No rendering expertise required to get started & create ” amazing 3D visuals.

NOTE: Typically the most effective results (time wise) usually relies on having a good graphic card & well spec’d machine.

KeyShot is widely recognized as the best rendering software for SolidWorks; said to be the fastest, easiest, and most

KEY RULES FOR GREAT RENDERS: • Use Photoshop for postprocessing & colour adjustments after the render. You can save both time & computer resources!

• Custom lighting is a must, it works same as a photography lighting set. You can fully create custom lighting environments in less than 5-mins with practice.

• Fillet all the visible corners: There are no perfect 90 degree corners on this planet!

• Add some small imperfections to the surfaces!

• Ask for feedback/advice from community members!

• There are many tutorials!

• Reuse your models! You can use other people models too! (not for your academic assessed submissions) RENDERING ON SW: Many used to use PhotoView 360 prior to KeyShot. Some still use this if they do not have access to other rendering software.

Check out the SolidWorks help page for PhotoView 360 alongside online tutorials on photorealistic rendering with SW & the O’Reilly rendering/ visualisation playlist.
