The Difference Between AutoCAD and SolidWorks

Submitted By: Jason Kay
SolidWorks is what we call a "parametric" solid modeller used for 3-D design. Parametric means that the dimensions can have relationships between one another and can be changed at any point during the design process to automatically alter the solid part and any related documentation (blueprint). AutoCAD, however, is primarily a 2-D design tool with some, but limited 3-D capabilities. It is very simple compared to any parametric solid modeller (although 3D is improved in AutoCAD 2007). Autodesk (the manufacturer of AutoCAD) makes a product that is nearly identical to SolidWorks, called Inventor, which is a parametric program for design of solid parts and assemblies.
SolidWorks is a 3D mechanical CAD (computer-aided design) program that runs on Microsoft Windows. SolidWorks files use the Microsoft Structured storage file format. This means that there is various files embedded within each SLDDRW (drawing files), SLDPRT (part files), SLDASM (assembly files), with preview bitmaps and metadata sub-files. Various third-party tools can be used to extract these sub-files, although the sub-files in many cases use proprietary binary file formats. SolidWorks is a parasolid-based solid modeller, and utilizes a parametric feature-based approach to create models and assemblies. Parameters refer to restrictions which values determine the shape or geometry of the model. Parameters can be either numeric, such as line lengths or circle diameters, or geometric, such as tangent, parallel, concentric, horizontal or vertical. Numeric parameters can be associated with each other through the use of relations, which allows them to capture design intent.
AutoCAD is, just like SolidWorks, a Computer Aided Design software application for 2-D and 3-D design and drafting. AutoCAD was one of the first CAD programs to run on personal or home computers, notably the IBM personal computer. At that time, most other CAD programs ran on mainframe computers or mini-computers that were connected to a graphics computer terminal for each user. Early releases of AutoCAD used basic entities such as lines, poly-lines, circles, arcs, and text to ultimately construct more complex objects. AutoCAD has since started to support custom objects through its C++ Application Programming Interface (API). Modern AutoCAD includes a full set of basic solid modelling and 3-D tools. With the release of AutoCAD 2007 improved 3D modelling saw the light, which means better navigation when working in three dimensions. It also became easier to edit 3-D models. The mental ray engine was included in rendering and thus it was now possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and network modelling. At this moment, AutoCAD only runs under Microsoft Windows operating systems. It is available in 32-bit and 64-bit versions. AutoCAD can run on an emulator or compatibility layer like VM-ware Workstation or Wine, although various performance issues can arise if you work with 3-D objects or large drawings.
Choosing a system that works for you depends solely on the type of work you want to do. Many experts say that SolidWorks is more effective when working on 3 dimensional designs and that AutoCAD is the way to go for 2 dimensional design.

Terreon Lav Deck Submitted By: Patricia Holland

Submitted By: Patricia Holland
The Terreon Lav Deck is the latest innovation using the unique Terreon solid surface material. It is a solid surface counter top with integral sinks or sink and coved backsplash. The deck can be equipped with an optional faucet, drinking fountain, waste receptacle, four sided drip ledge, and / or soap dispenser openings. Another option for the buyer is to order the deck without a faucet or drinking fountain and request a drilled unit for four inch centerset, eight inch centerset, or centershank faucet mounting. It is always a good idea to check local ordinances and codes for compliance issues.
The Terreon Lav Deck can be ordered with either the standard Terreon or the Terreon (RE) recycled material. Both materials have similar qualities. Terreon is comprised of a blend of acrylic modified polyester resin with UV stabilizer, alumina tri-hydrate, and mineral fillers. Terreon (RE) recycled is a similar densified solid surface material but it is comprised of eight percent bio-based resin and twenty-five percent pre-consumer recycled granules. Both Terreon materials are bound by a two step catalyst and heat to create a very durable and attractive surface material. Both Terreon and Terreon (RE) are certified as GreenGuard low-emitting materials. And both materials are sold with a ten year warranty.
The Terreon Lavatory Deck has numerous inherent qualities that make it a highly desirable surface material. These qualities have made Terreon a popular choice for locations that have a high volume of commercial traffic and / or vandalism issues. In addition to being durable, Terreon is also smooth to the touch and non-porous. This smooth non-porous material has no cracks or crevices and prevents an accumulation of mold and bacteria. It is very easy to clean and it is chemical and stain resistant. It is also impact and scratch resistant which is a highly desirable feature against vandals. Should the surface be damaged it is easy to repair with an economical Terreon repair kit. Terreon is also resistant to heat and to damage caused by constant contact with water. There are thirty four colors available which allows the buyer a great deal of flexibility when coordinating colors and layouts. And the composition of Terreon is homogenous which means the color is evenly distributed throughout the material. During manufacture, Terreon is combined with the latest technology in UV light stabilizers. With a one half inch standard thickness, both Terreon and Terreon (RE) are workable using standard power tools.
The care and maintenance of the Terreon Lav Deck is very easy and simple. Daily cleaning can be done with standard commercial or household cleaners such as Formula 409 or Windex. Tougher stains can be removed with Ajax, Comet, Soft-Scrub and a green Scotch-Brite pad. More difficult stains can be removed with a light sanding with 240 grit wet / dry sandpaper. And the finish can be renewed with a maroon Scotch-Brite pad.
Terreon Lavatory Decks are ADA compliant and TAS compliant units are available. In addition, both Terreon and Terreon (RE) are certified by NAHB to meet Z124.3, Z124.6, and ANSI / ICPA SS-1-2001 standards. The deck is approved by the Uniform Plumbing Code through the International Association of Plumbing and Mechanical Officials (IAPMO). Therefore it is certified for use in both the United States and Canada.

Using MP3 Renamers to Save Time and Money

Submitted By: Paul F. Wood
Whether music is part of your professional life or just something you love, chances are you have a computer that is overloaded with musical files. And there are probably a variety of places that those music files have come from. Maybe a lot of those files have been imported to your computer from CDs in your own CD collection. Lots of the files may also come from an online music program. Still others you may have been found on various websites or gotten through e-mail from friends.
All of these different types of files piled up on a computer can get quite messy. There is no organization of the files either in the way they are titled or the information within them. If you're ready to make sense of all of this, you have two options. You can always go file by file changing each and every name. The other way to go is using an MP3 renamer.
For many, the idea of changing file names doesn't seem so bad. However, once you multiply the few seconds it takes to change one filename by hundreds or thousands there are many hours lost. Instead, you could use that time for all sorts of other things. Do you have business or personal things you'd rather be doing with this time?
By enlisting the help of an MP3 rename program, you'll be able to make file changes quickly and easily and spend the rest of your time more wisely. How does it work?
Title Changes
The first thing you are going to want to do is make all of your titles make sense. With access to a rename MP3 program, you can highlight an entire group of files and change the names all at the same time. It will then remove the current name and replace it with your text and numbers, sequentially with just one click.
Album and Artist Information
Often, the album and artist information gets lost somewhere in translation as music files are being digitally loaded into a computer. It takes little more than a quick click to be able to highlight a whole group of songs and add that artist in information in with a renamer program.
Text Find and Replace
Did you initially have a system for naming all of the files in your library? Did your music library initially start with a file naming system? But now you'd like to make a few alterations to your old system. Just one action will find and replace words or phrases out your files.
Inserting the Track Numbers
It isn't just a matter of wanting to wipe out the existing name and overwrite it entirely - often you'll just want to use music information in a specific part of the name. A classic example is track numbers - you will probably want to insert them at the beginning, but make sure that you can pull the numbers straight out of each mp3 file and use them in the name; you should also be able to place that information wherever you like.
