Utilizing CAD Files

When I was in 6th grade, our art teacher, Mrs. C, taught us to draw fruit one day. I was academically gifted (I’d had straight A’s since 1st grade) but I was AWFUL at drawing. I was doing OK with my orange, apple, and even my banana. When it came time to draw a pear, I realized I had 35 cents in my pocket (that’s what milk for snack time cost) so I pulled out that quarter & dime, used them to trace a quarter-sized circle with a dime-size circle slightly intersecting it, erased the middle parts, and “free-handed” little arcs to complete the pear shape. Mrs. C told me I wasn’t allowed to do that and gave me my first bad grade – ever. Now, I LOVE going to art museums and taking in the wonders of those who are far more skilled than I with pen and brush, but I STILL have no aptitude or desire for drawing anything myself….with a pen or brush, that is.

My first job out of the Navy involved some very basic CAD use…mainly making simple changes or additions (and usually just title block text) of existing drawings. As I more familiar with CAD, I realized the method for drawing a pear shape in CAD was, in fact, my own personal grade school method: intersect two circles, trim, and fillet. So there, Mrs. C!

My next job took my CAD utilization a bit further…making assembly drawings of systems, using existing CAD files for the individual components that made up the system. The key word there was “existing” – the First Law of CAD is, “Don’t ever draw anything twice.” So, I’d get CAD files from the manufacturers, insert them into my template, put them where I wanted them to be in relation to the other pieces of my little puzzle, send the drawing(s) to the end user for piping and foundation prep, and as long as the folks in the shop followed my drawings (which is was hard not to), everything worked out great.

Now, this was way back in the 1990’s, so I got most of my CAD files via email, and, occasionally, on 3.5″ floppy disks or CD’s. EXAIR Corporation has offered drawing files for our products in our CAD Library for many years now. You can always find four fundamental file extensions:

  • PDF – these can be opened with Adobe Acrobat…they’re “just for looking at”. They don’t denote any particular scale, and won’t directly import to a CAD file. They’re useful for quick & easy answers about overall dimensions, bolt hole sizes, thread pitches, etc.
  • DWG – this is AutoCAD’s “native language.” These files will open seamlessly in AutoCAD, if that’s what you’re using, along with many other programs. But, if it doesn’t.
  • STP – we’re well in to the 21st Century, and many designers have moved on from the above mentioned 2D files to solid models. Most solid modeling programs are compatible with these files.
  • SAT – these are, to STP, what DXF is to DWG…a “more friendly” file for certain solid model programs.

With the launch of our new website, we now offer 64 native extensions so you (hopefully) do not have to modify, import, or convert any drawing that would take additional modification – just download the file you need right from our Resources, 3D Models and CAD drawings link. And dare I say, if you can’t find the extension you need, you are using some fairly obscure software – perhaps an SAT or STP file will suit you.

If you’re designing a system or making an assembly drawing incorporating EXAIR catalog products, we have all of these in the CAD Library. If you need one for something that’s not in the catalog – a Super Air Knife less than 60″ long with a Plumbing Kit installed, for example – we can provide that as well...just contact an Application Engineer.

Communication Is Key

Effective communication is a key interpersonal skill and learning how each of us can improve our communication is beneficial to all. Communication is a two way process, so improving communication involves both how we deliver and listen to the message. To best service our customers, EXAIR has many ways to share and receive information.

There are the standard methods, of course, that have been around for years.  Phone and fax are still very useful, and everyone has noticed that fax is slowly becoming less utilized. As dreaded as it may be, email is certainly a valuable way to communicate, especially as it allows ‘attachments’ such as photos, which as the saying goes, are definitely worth a thousand words. If video or 3D models are exchanged I am certain the number of words increases.

The newest technology for communication is via ‘chat’ which can be accessed from the EXAIR website. Here, you can chat with an Application Engineer and do something as simple as confirming a part number to something more involved like sizing a Cabinet Cooler System.

The US Postal System is still a valuable communication tool, as we send out the EXAIR Catalog (currently volume No. 30) and the EXAIR-Mail (Number 109/Fall 2016 issue just went out), and some Purchase Orders still are dropped off by the Postman.

Another method of communication is face to face.  We have what we call the ‘Demo Room’ here at the factory in Cincinnati, OH.  In this room, we have every type of our Intelligent Compressed Air Products, in just about every size offered, ready for demonstration and testing to your application.  We’ve had visitors from all over the world come in and share face to face their applications and collaborate with us and test out the EXAIR solution.

There is also the EXAIR website, where we provide a plethora of information regarding the EXAIR product lines, CAD and PDF librariesCase StudiesPresentations, and the Video Library just to name a few.  Also, here is where you can Request a Catalog, Sign up for E-News, and Check List Pricing.

Lastly, and since you are reading this you already are familiar with the EXAIR Blog – a great way for us to share with you our musings and thoughts, in a way that makes it a personal take on the EXAIR products and our interactions with our customers.

Effective communication is very important to us and what we do here every day.  Feel free to utilize one or more of the Contact Us tools to communicate with us and we’ll be in touch!

EXAIR.com offers Numerous Engineering Tools

Today, I want to take the opportunity to highlight some features on EXAIR’s website. EXAIR provides a website for technical information on products, point of sale and research on compressed air topics in general. For instance, if you would like to know, How a Vortex Tube Works, the Droplet Size of our Atomizing Spray Nozzles, or a Blow Off Comparison between a compressed air powered air knife and blower system, follow the links above and navigate to the topic that interests you on our website.

 

Our Air Savings Calculator will show you total dollars saved and payback time.

Our knowledge base features the CAD Library, Case Study Library, and Application Database. The Air Data Library is invaluable to any engineer specifying a compressed air piping system. It also features a great article for calculating air consumption at various inlet pressure. One of my favorite features though is the Air Savings Calculator.

The Air Savings Calculator allows you to calculate the cost of compressed air for various devices.  The cost of compressed air for high usage device like open blow offs, drilled pipes and uncontrolled compressed air devices can add up quickly. With the air savings calculator, you can quickly find out how much those (8) 1/16″ inner diameter 18″ long open pipes are costing you per year ($2,016 if you are operating at 80 PSIG).

Some of the material that we make available to our visitors we request that you register on the site. The registration is a simple process to complete. Why would you want to take the time to give us you information? First, registering on EXAIR’s site gives access to our library of product applications for the last thirty years EXAIR has tracked how our products have been used to help our customers solve their industrial needs. Second, EXAIR members are granted access to CAD models in 2D and 3D of our products. The 3D models can easily import into AutoCAD Inventor®, Solidworks®, or PRO Engineer®. These models will allow you to easily import EXAIR products into your design to verify the fit and mounting in complex systems. Third, EXAIR Case Study library offers detailed analysis of economics, safety, and utility savings of using EXAIR products.
