3D CAD Modeling, PLM and PDM

Many times, when we get requests for 3D Modeling Services, the company making the request has digital files that have been acquired by scanning old Mylar of paper 2D drawings.  Often these are scans of parts, and/or assemblies that are used in long-life products, such as aircraft, naval ships, and heavy machinery.  What they don't have are 3D models. 

The reason they need 3D models is so that they can incorporate the parts into their current 3D CAD system, often using Solidworks or Catia.  Once the models are in their CAD system, they can retrofit, recreate, or machine replacement parts for their long-life products.

Keeping Up with Technology:  Mold-filling Simulations for Manufacturers

Keeping Up with Technology: Mold-filling Simulations for Manufacturers

Injection molding is one of the most common modern methods used for manufacturing parts.  It’s a great technology for producing high volumes of parts, in a multitude of materials – metals (called die-casting), glasses, elastomers, and polymers.  It’s simple, really – the heated material is forced into a mold that is shaped like the part you need.  The material is cooled, hardens and…voila’… you have your part. 

As simple as the process is, parts to be injection molded must be very carefully designed.  The material used for the part, the desired shape and features of the part, the material of the mold, and the properties of the molding machine must all be considered.

That’s where mold-filling simulations come in.

Can You Outsource 3D CAD Modeling?

Before you hire a freelancer to pick up the extra tasks on that new 3D CAD Modeling job that needs done, you should consider the pros and cons of outsourcing your 3D CAD Modeling.  Is outsourcing a smart choice for your company?  If it is, do you want a freelancer; or a bona fide CAD outsource company?  Located in U.S.A?  Or offshore?  What should you pay?  How do you ensure the work is done right?  Let’s start at the beginning…

Why 3D CAD Models Are Used in the Design Process

Why 3D CAD Models are Used in the Design Process

With globalization has come the requirement for product manufacturers to respond to the ever-changing needs of consumers faster, better, and cheaper.  These demands shorten product life cycles and increase the need for new models, customizations, advanced technologies and more. 

It’s been proven that companies which respond to these consumer demands are more innovative, more successful and more profitable than those who don’t.  One way in which manufacturers keep one step ahead of the competition is by concurrent engineering – the process of engineering and manufacturing being enabled simultaneously from shared 3D CAD data.  For instance, 3D CAD models can be used as virtual prototypes, eliminating the time-consuming requirements for multiple physical prototypes until the engineering is “right”.

3D CAD – A Primer

3D CAD – A Primer

3D CAD comes in different “flavors” that are used differently and that require the CAD technicians to design their virtual components in a different manner for each.  Here is a list of the types of 3D CAD this article discusses:

    • 3D wireframe
    • 3D "dumb" solids
    • 3D parametric solid modeling

3D wireframe, while not often used today, is worth mentioning simply because the approach to 3D wireframe is similar to that used in 2D CAD systems.    Persons familiar with 2D CAD will understand these concepts:  (1) each line has to be manually inserted into the drawing; (2) the final product has no mass properties associated with it; (3) the final product cannot have features added directly to it.   The wireframe model  is used to make the final engineering drawing views.
