Solidworks Aston Martin One-77 by Romain Genistou

Hello again, and boy has it been a long and busy several months for me.  I have had many changes as well as obstacles to overcome along with the coming of the new year and I am hoping for a bit more smoother sailing in the months to come.  So with that said, I am looking forward to getting back on track with my posts.  I hope all of you are having a wonderful new year and I also want to thank all of my dedicated readers out there for returning again and again to see what new and interesting insights there are in the world of modern technological design and entertainment.

Lately, I have completed a variety of Solidworks tutorials and I would like to share them with you.  One tutorial in particular is the Aston Martin One-77 body modeling tutorial by Romain Genistou.

I found this tutorial to be full of surprises, and it leaned towards the more complicated and challenging of car body modeling tutorials I have worked on as of yet.  While most Solidworks tutorials I have come across seem to be a step-by-step, hand-in-hand walkthrough of the complete tutorial; this tutorial made you strap on your thinking cap from time to time.  I found this true when especially working with the PDF version of this tutorial.

The creator of this tutorial, Romain Genistou, has a website named Solidworks Insight at www.solidworks-insight.com.  This website has a few wonderful introductory tutorials for the Solidworks student.  Most of the tutorials on this site are free, however, there are a couple that require you to pay in order to complete the tutorial in its entirity.

And so it comes to happen that Romain and Jan from www.learnsolidworks.com decided to meet and together they revised the tutorial in its entirity before  I had originally purchased the PDF version of this tutorial from Solidworks Insight before Romain and Jan collaborated on the LearnSolidworks.com edition, and I found that version to be incorrect in some areas of the design as well as missing important steps and information.  This was particularly noticeable in things like designing projected curves and connecting areas of the rear bumper area.  The LearnSolidworks.com tutorial is much more polished and goes into a bit more detail on certain questionable areas of the design.

There are certain areas of the newer version that need a bit more clarification, such as working with boundary and filled surfaces and the parameters which determine what is the best method to use between the two.  Also, there was not a great amount of detail on knitting surfaces in the model.  When modeling the Audi R8, there was quite an amount surface knitting involved, and the tutorial (although long), felt much more thorough and professionally complete.  I found myself referencing the R8 tutorial for a variety of areas including working with assemblies and making the construction lines for the vehicles axles and wheel placement.

The Aston Martin One-77 tutorial is now available on www.learnsolidworks.com for a price of 347 euro, but for a novice designer who is interested in vehicle body modeling, the information and instruction you receive is invaluable.

Solidworks Audi R8 Tutorial by Dan Lavoie

Well, hello again from your FAVORITE blogger!  I know, I know….I have had many a delay in posting my blogs as of late, but I have been excpetionally busy for some time now with many, many things which never seem to get accomplished and go away.  I have lately accomplished something worth blogging about, and I thought I would share it with you.  For anyone wanting to learn and practice surface modeling in Solidworks, there is a variety of tutorials available throughout the web.  Three key websites for Solidworks tutorials are: www.learnsolidworks.com, www.solidworkszen.com, and www.solidstufflearning.com.  The first two websites I mentioned have some very in-depth and advanced mechanical design tutorials.  I will go into more detail on these websites at a later time.  The last website I mentioned has amazing surface modeling tutorials available for a price.  But, hey, nothing is free in this world now, right?  In fact, things are REALLY, REALLY, REALLY, REALLY EXPENSIVE, aren’t they!!!!!  Even that piece of dirty half eaten, maggot infested, decaying, diseased chicken bone you just were caught stealing out of the garbage bin could potentially be pricey…..you just never know, do you?  Chances are something like that wouldn’t be pricey at all…..however, it could have been placed there as a marker for some member of a bloodthristy crime gang for whatever reasons, and you just took it….and interfered with their business, on their turf!  Like I said….you never know.  So, with that said, let me continue.  Where was I?  Oh yes, so right now, if you can fork out $90 for a Solidworks tutorial on this site, you can purchase a wonderful tutorial on how to model an Audi R8!  Just look at the stunning pictures I created of my Audi R8 from start to finish!  Wooooowwwwww, and who knew Solidworks could create such purrrdy pictures?  I do hope you have a LOT of time set aside to do this project if you are considering it, because it does take a bit of time to complete…..just a warning!  However, when you finally complete the project, you will feel a sense of accomplishment and you will learn quite a bit in the process, especially for people who need to have things shown over and over to them to get it through their thick heads, like me!  (Not from years of suffering fits of delerium from learning things like these projects…..no, not at all, hahahahahaaaaaaaaaaaaaaaaa! :(:):((((!%$#%$#@!!!!!

When you purchase the download, you get access to a zip file that you must unzip and then you will get a media player software access to play the included video tutorials to complete the project.  Each video runs about a minute to three minutes max.

I found the project to be very informative and I thought that it instructed me well on a variety of fundamental functions in surface modeling.  These key designer methods are as follows, but are not limited to:

  • Curves and projected curves
  • Converting Entities
  • Splitting surfaces and split lines
  • Offsetting lines and surfaces
  • The spline and relations
  • The use of vertical, horizontal, perpendicular, parallel, tangent, and other relations
  • Piercing endpoints to other lines
  • Planes and sketching on planes to create complex shapes in difficult areas
  • Extruded boss/bases, extruded cuts, revolved boss/bases, revolved cuts, lofted boss/bases, swept boss/bases
  • Boundary surfaces
  • Trimming surfaces and entities
  • Cut with surface
  • Knitting surfaces
  • Deleting faces and bodies
  • Fillets
  • Thickening surfaces
  • Combining bodies
  • Cut, copy, pasting and moving entities and bodies
  • And many more!

This was an extremely fulfilling tutorial on all fronts.  I felt it showed me and ingrained some of the essential things that any modeler needs to be introduced to surface modeling in Solidworks. If you have $90 available and you are willing to set aside some time to work on a project like this, then I would highly recommend that you try this tutorial.  Not only is there an Audi R8 tutorial available now at half the price, there is also a tutorial on creating an F16 fighter jet, a Ferrari F-430 tutorial, and a Lamborghini Gallardo tutorial available now at HALF THE PRICE!

With that said, I wish you luck.  I am going to go now and work on my next project.  YAY!

CNC Hot Wire Foam Cutting Machine

A CNC hot wire foam cutter is a computer controlled machine used for mainly cutting Polystyrene foam (also known as EPS foam) and similar materials, such as polypropylene (Known as EPP) and polyethylene (known as PE).  The machine consists of a wire running between 2 towers, which is heated via a hot wire power supply, thus melting and cutting the foam into the desired shape.  The towers can move in an X-Axis (right-left) and a Y-Axis (up-down).

Cutting the foam is done in 3 basic steps:
1. Drawing the desired shape to be cut.
2. Converting the shape into G-Code
3. Running the machine with the software to execute the desired shape.

Any CAD software, such as AutoCAD or Corel Draw can be used for drawing the shape, as long as the file can be saved in a DXF format.  There are various CAD files in the market.  More recommended ones include Instant Engineer 14, which can be purchased online for few dollars, DesignCAD, AutoCAD and TurboCAD.  Another CAD software is DevFoam, that combines both the drawing and the G-Code generation.  It is a user friendly application for cutting foam with a 4 Axis CNC machine.

Next step is to convert the shape into G-Code.  The G-Code is another name for the computerized tool by which we tell the machine what to cut and how to cut it.  For the conversion one can use software such as DeskCNC, DevCAD or FoamWorks.
DeskCNC was originally designed for a 3 Axis CNC Router machines.  It was later on modified to enable a 4 Axis foam cutters to run as well.
FoamWorks is known for its simplicity and being a user friendly software.  It is designed to drive a 4 Axis foam cutter via a parallel port of any windows based computer.  It can cut any shape, but works best for cutting RC wings.

For the last stage of running the machine, software such as Mach3 and DeskCNC can be used.  The Mach3 program is a G-Code reader.  It allows you to turn your PC computer into a 4 Axis CNC controller for machining and cutting.  It is an operating system for running the CNC hot wire foam cutter.  It was originally developed for the home hobbyist, and later modified for use for any CNC machine operation for industrial use.

The use of Solidworks design services in engineering products

In an engineering firm, you are often faced with a lot of tasks to achieve in a limited time frame.  You have your engineers fully engaged in mechanical designs of different specifications and standards.  You may have considered having more experts coming onboard to resolve your time constraint problems.  As true as this may be, you can have an option of hiring equally experienced experts through mechanical design services at a much affordable and realistic cost.

Outsourcing your non-core mechanical designs to mechanical design service companies which specialize in them is the modern approach to engineering today.  Many of them you’ll find around would handle your modeling in 3D, analyze your design specification and layout and provide the required output using latest engineering and design software such as computer aided design (CAD) and computer-aided engineering (CAE) software.

If your company requires the services of the areas underlisted, you can make a call through to have them regularly fill your needs.

Mechanical engineering

• You can have services of the following readily available if you are in short of man hour to complete your mechanical engineering works.

• FEA analysis service

• Simulation and animation service

• Standardization of design

• Design modularization

• Design conversions from ISO to ANSI or otherwise

• 2D to 3D modeling conversion

• Design scaling

• Design quality measure and compliance

• You can also have services in value engineering

These services and much more will provide the cushion you’ll need to meet up your company’s target and within a considerably affordable budget.

Solid works design services

SolidWorks is one program employed by many engineers in their designs.  It is a windows based software that will give your design layout and sketch the modeling that meets the required specification. This is carried out through computer-aided design (CAD) and computer aided engineering technology (CAE) technologies.  As a service company will provide, you’ll get the best for your money’s worth and right on time too.

This mechanical design tool will bring out your product in the variant of the model you have requested.  With experts available, you have no need to bother what comes up on your request as all will be completed above and beyond your expectations.

FEA (Finite Element Analysis)

The structure of a design is known through its design components whether they measure up to standard or not, and are the pillars of the final product.  A well laid structure gives a good final product while on the contrary, a bad product is envisaged.

Finite element analysis service is one more area in your engineering work that can be handled outside your core projects.  Engineering designs are with standards and must meet specification. Therefore, the analysis of finite elements for qualitative and quantitative compliance will be well handled with the utmost professionalism of quality standards that are required.  The FEA services experts are experienced hands who would deliver as expected for your ongoing project.

Working with good engineering services provider is an added value you can access for your company.

Solidworks And Sheet Metal Design

Solidworks has been specifically designed to help manufacturers design and create sheet metal parts.  Used primarily to close the gap between designers and sheet metal manufacturers, sheet metal design manufacturing with Solidworks helps keep prices low and hastens delivery times.  Solidworks’ user friendly interface allows engineers and designers to model completed parts, generating three dimensional models which can then be used by manufacturers to build the finished product.

One of the countless things that Solidworks enables engineers and manufacturers to do is to establish, for the purpose of each product, what type of sheet metal they will be using.  This includes factors like how thick the sheet metal is.  Engineers can then design sheet metal parts virtually and determine whether the material can indeed withstand the pressures placed upon it by the design.  Furthermore, sheet metal panels can be named and labeled so as to avoid confusion concerning how many of which panels to fabricate.  Later, this also helps in assembly as all sheet metal panels will be properly labeled as to their purpose and where they fit into the overall product design.

Solidworks software will also allow the engineer to add form radius, multiple or layered extrusions and other features after the product has been assembled in the virtual design.  This helps both the designer and the manufacturer to align perforations, tabs, and other features that need to be lined up on numerous complex sheet metal panels.

Solidworks allows the design and fabrication of very complex features, allowing both designers and fabricators to verify tolerances and clearances, ensuring that the product which the engineer has designed can actually be fabricated and, eventually, assembled.  Using this software engineers can view the design with small spaces so as to allow the software to unfold the computer model.  This allows design features to stand out, so that they will be seen clearly.  This feature is useful when the panels will be touching in the actual product but need to be seen as individual components by the fabricator in order to construct them correctly.

By far the best aspect of the Solidworks design package is that it allows manufacturers to modify the design as needed. The software will also help designers to take into account the effect the changes could have on the rest of the design.  The clear advantage of this is that design flaws and inconsistencies will be caught prior to the beginning of the manufacturing process, most likely saving you a lot of time and wasted materials.

Engineers find that they are able to move a product from conception and modeling through to a workable design more easily if they use solidworks software for sheet metal manufacturing.  If the design is clearly shown and easy to interpret, the manufacturer will be able able to construct components which will fit and perform exactly as the designer intended, leading to a more efficient production process.  Efficient production results in less material being wasted, fewer man hours, lower costs, and a higher profit margin.

Revit Families for Beginners

Many fresh Revit technicians or architects who go through Revit training spend quite a lot of time in understanding the concepts behind developing BIM families.  Understanding the concepts and analyzing the role of Revit families in a particular project is very important.  Creating Revit content or families is vital for every BIM project, regardless of project size or complexity.

How to get there, is the question?  Let us talk about the concept and give beginners an idea of this essential part of BIM.

Revit family and content creation, is considered extremely important in the field of BIM.  Companies aim to develop families in order the maintain a seamless work flow within projects.  What are Revit families and why are they so important?

Basic Overview :
As discussed earlier, families constitute of elements with similar parameters which are the building blocks of a revit model.  Revit families can be simple or parametric in nature.  Parametric families are extremely important and sought after widely owing to its multiple advantages.  Families can be created from scratch depending on building requirements and later modified according to right project environment.

Types of Families:
Revit families can be categorized under Architectural , Structural, HVAC Electrical, Fire protection and Plumbing families.  Ceilings, doors, windows, furniture, fixtures, walls, curtain walls, etc., fall under Architectural Revit families.  Pipes, faucets, tubs, pots, toilets fall under Plumbing category while air diffusers and conduits are developed under HVAC and Electrical categories respectively.  You cannot modify or change the categories available within the Revit software but you can add types of families required.

There can be numerous variants within same family types.  These variants can have different dimensions, material specifications and parameters that differentiate each family variant from another one.  For example a kitchen faucet can have 3 variants, one can be small with a steel finish,  another can be a bit large with a porcelain finish, and one can be an oval shape with a tile finish.  Key concern is the parameter that is used and the values given to them.  The key point to note is that these four variations have the same set of parameters; however, the value of those parameters varies.  Parametric Revit families can be used within any project environment.

Changing or adding parameters is a tricky part.  All Revit modelers need to identify the difference between modifying parameters of family groups and individual families.
