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.

Can we optimize Revit for interference checking?

Well, people who are not related to construction industry get confused when they hear that Revit can also be used for determining clashes between models.  The reason for that is, normally Navisworks is optimized by AEC professionals for executing clash detection services.  When client companies get to know that clashes between model elements can also be figured out in Revit they are often shocked to hear that.

But the fact remains that, Revit is the most powerful software developed by Autodesk.  It can perform many functions apart from modeling which is its specialty.  For example the software, helps architects and engineers in coordinating multidiscipline models, creating sketches and for providing realistic effects to the models by rendering them.  In fact Revit coordination modeling services have become very popular among AEC professionals now days.

However, its Interference checking feature is very important for design development teams.  Interferences between architecture, structure and MEP models can be easily figured out in Revit by BIM modelers.  First of all, when all the different models are developed by a same company, it becomes very convenient for the multidiscipline design development teams to collaborate with for determining clashes.

Revit users can determine clashes between their own model elements, as well as between multidiscipline models such as between architectural and structural model.

A quite simple method is applied by Revit users to find out clashes.  When clashes are determined within the model elements of a single model, its users simply have to compare the location of various elements.  By comparing their location, engineers can easily understand whether they are colliding with each other or not.  If in case location assigned for a model element does not interfere with the location of other model element that means there are no issues between them.  But if two or more than two model elements interfere with each other’s location that means there is a problem in the design. And hence clashes can be determined easily.

The same formula is applied when it comes to determining clashes between different models.  In this case Revit users are first required to link a model into the host model.  Once the model is linked its users have to compare the locations of the elements of a host model and linked model.  This helps in figuring out whether the model elements of host and linked model are fighting for the same location or not.  If in case they are fighting for a same location that means they are interfering with each other.

In this way Revit users can figure out all the clashes and can eliminate them in time before they could become a serious problem for architects and engineers.

Solidworks And Sheet Metal Design

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.

Auto CAD DXF Three Common Mistakes That People Make When Converting Patterns to DXF-AAMA File Format

Auto CAD DXF Three Common Mistakes That People Make When Converting Patterns to DXF-AAMA File Format

Hello my readers, the modern world of fashion design and smart fashion requires the use of computer technology and, of course, the use of a variety of computer applications to work with creating modern apparel in precise designs and dimensions.  The success of a modern fashion label requires the knowledge and use of this technology to stay on top and ahead of the global competition in the fashion world.  In researching the use of nesting programs used in fashion production, I found some interesting information regarding the use of DXF files, which are AutoCAD related files, or Drawing Exchange Format files.  These files are used often in nesting programs, where these files are placed on a layout that is used to cut the specific pieces according to the nested file’s dimensions.  The original design and dimensions are created in a program such as AutoCAD, and then imported into a nesting program where they are placed to be cut or sewn on a machine for mass production.  So, please take the time to read some of these mistakes commonly made by people when they are trying to convert a pattern into this type of file.

DXF-AAMA is a file format developed by the American Apparel Manufacturers Association in an attempt to solve the difficulties of using DXF files.  Now when talking about converting a pattern into a DXF (Drawing exchange Format. ) you will find that your converted pattern does not contains neither scale or units nor usually any method of reliably describing what needs to be cut, drawn, drilled or notched in your pattern file however, this file is the most commonly used format for exchange of drawing files.  Listed below, are three of the most commonly made mistakes made by people not software when trying to convert a pattern into this type of file.

1rst Problem: Thinking that your pattern will be a print file and not a cut file.

Thinking that your converted DXF CAD pattern file will be kept in a computer system for further modifications is a common mistake.  Most of the time, your converted file pattern will be neither needed nor wanted.  The purpose of the document is to generate tool paths for a machine.  So keep that in mind when formatting and exporting.  In most cases nobody will need to open the drawing in a CAD program, so eliminate what is not essential.  Think about what is needed in a drawing, format and export accordingly.

2rd problem: Not making the outline of your pattern into one closed polyline creating nesting problems.

In computer graphics a polygonal chain is called a polyline and is often used to approximate curved paths. Not closing your pattern outline will create problems when nesting your pattern and processing your DXF file.

3rd problem: Including objects in a drawing that are unnecessary.

Information such as Fabric type, sewing details, pattern codes, designer comments etc.  They all should not be included in your pattern as these will obstruct the conversion process.  Think of a way to hide or make invisible these text blocks put a reference layer or delete all information before exporting to DXF.

To conclude, three of the most common AAMA DXF pattern conversion mistakes are done by people and not by software.  Converting a pattern into a DXF (Drawing exchange Format.) will allow other CAD programs to read and import your digital pattern into tangent or any other nesting and plotting programs.  Some information lost in the conversion process include: No available information to find if your pattern has a scale or units, notching information, drill marks etc.  Not making the outline of your pattern into one close polyline and including non essential objects like text blocks all around a pattern will all contribute to badly formatted DXF files.

Interesting Career Prospects for Revit Practitioners

With the building and construction industry worldwide moving towards using building information modelling (BIM) approach for designing, documentation, construction, and facility maintenance, proficiency in BIM tools and applications is becoming a sought-after skill in the modern AEC workforce.  Whilst there are several applications that enable BIM, Autodesk Revit is one of the powerful tools used by reputed architects, structural engineers, and MEP engineers worldwide.

Architectural, engineering, and construction management students and professionals proficient in Revit have a greater scope to succeed in the modern AEC industry compared to those who are just specialised in 2D CAD technologies.  As the crucial industry stakeholders worldwide push towards transitioning to smart BIM technologies, interesting prospects related to BIM jobs are poised to open up.  Autodesk certified candidates with medium to advanced level proficiency in executing Revit jobs can seek the following career advancement opportunities:

1. Revit Modeller (Architecture)
Candidates with 2 to 5 years of hands-on experience in working with Revit Architecture can enter architectural firms or design outsourcing firms as Revit Modellers (Architecture).  An important aspect of the profile will certainly include conversion of 2D/3D AutoCAD drawings/models into Revit BIM files and reusable Revit families. For this, the incumbents should be well versed in BIM concepts and an exposure to other related architectural tools (not necessarily BIM tools) including AutoCAD, Navisworks, and GRAPHISOFT ArchiCAD. Excellent visualisation skills and experience of working with diverse projects of simple to complex nature is invaluable.

2. Revit Modeller (MEP / HVAC)
Professionals having mid-level experience of using Revit MEP for modelling MEP and HVAC systems can take the opportunity to work as Revit Modeller (MEP / HVAC) for building systems design consultants or MEP design outsourcing firms.  For the incumbent to be successful in this role, he/she should have an in-depth know-how of HVAC and mechanical services systems generally adopted in commercial, residential and mixed-use facilities.  As far as software proficiency is concerned, barring Revit MEP the candidate should ideally have exposure to modelling in applications, such as CADDuct and CADMEP+.

3. Project Manager (Revit)
Project Manager (Revit) would be an ideal profile for Revit practitioners with 5 – 10 years of experience in implementing BIM standards using the Revit platform.  The role requires coordination with the client’s design team, setting BIM execution plans, and distributing individual/federated BIM models to the production team using Revit worksharing capabilities.  He/she would need to train the project team on client’s BIM standards whilst keeping a tight control on the Revit BIM model by overseeing day-to-day tasks.  A crucial aspect of this profile would demand prompt resolution of any technical issues related to the master model.  Besides Revit, an in-depth understanding of clash detection tools, such as Navisworks proves beneficial.

4. Revit Coordinator
The Revit Coordinator position is ideal for a candidate having more than 5 years of hands-on experience of working with popular CAD and BIM applications.  His/her key role is to control and monitor design information exchange between clients and project team members using face-to-face and virtual BIM coordination meetings.  Familiarity with multidisciplinary design projects (residential, commercial, and mixed-use) is important along with an ability to conduct quality reviews of federated models and construction documentation.  He/she has the responsibility of understanding the BIM objectives of the client and maintaining the BIM model’s integrity to meet the required design and regulatory standards.
