EPDM: Copying data card properties from Part to Drawing

March 6th, 2014

Hey happy EPDM users !
Have you ever wanted to make a SW Drawing “copy” its properties from the SW Part card ?
I have ran into several customers wanting to do this for various reasons.
For example: You might want the DESCRIPTION from Part card be auto copied to the Drawing for that part.  (they would be the same usually, right ?)

Here’s how you do it:
In the DESCRIPTION variable, add a new ATTRIBUTE with BLOCK NAME of “$PRPSHEET” and ATTRIBUTE NAME set to same value as the Custom Property attribute (i.e. most likely “description”).

When you go to test this, you need to MAKE SURE you put some geometry into your test part and insert at least ONE VIEW onto the test drawing !!

This will also work just fine if the description is entered in the Save As dialog box for the part vs the data card. It all goes to the same place.

Holy cow… Did I just write a Blog on EPDM !??!

Circuit Works and Flow Simulation Working Together

February 25th, 2014

When you think about it, it makes sense that different parts of our SolidWorks Software work together to make a total package.  Keeping in this tradition now in 2014 Circuit Works and Flow Simulation work together to make your life easier.

2014 Flow simulation now imports the Circuit Works component properties and applies them automatically as boundary conditions in your Flow Simulation setup.  Previously these properties would be input manually.  Now we can import ECAD file PCB or Component Thermal Properties to Flow Simulation.

Some of the properties that can be directly utilized from Circuit Works are, Dielectric and Conductor Density, Specific Heat, Conductivity for PCBs, and Conductivity for Volumetric Heat Sources.

Two Import Options:

Right-click Heat Sources and select Import volume source from model. Select the heat sources to import in Item properties.
Right-click Printed Circuit Boards and select Import Printed Circuit Boards from model. Select the PCBs to import in Item properties.

If you are doing Flow Simulation on Electronics Enclosures check out the new Circuit Works import options.  This new feature is a great time saver.  Manually adding these properties on a typical circuit board (100′s of components) is tedious and time consuming.  Circuit Works integration brings this task down to a few simple clicks.

SolidWorks at the 2014 Winter Olympics

February 17th, 2014

What does SolidWorks have to do with the Olympics? If you attended SolidWorks World in January, you already know that the connection is with Geoff Bodine and Bob Cuneo, the two men behind the Gold Medal winning “Night Train” Bobsled.

Geoff Bodine, winner of the Daytona 500 in 1986, contacted Bob Cuneo, owner of Chassis Dynamics, in 1992 and together they partnered to form the Bo-Dyn Bobsled project.

Click here to watch Bodine explain how he came up with the idea to build an American-made, medal-winning bobsled.

After successfully winning an Olympic gold medal in Vancouver in 2010 with the bobsled, “Night Train,” the Bo-Dyn Bobsled project decided to utilize SolidWorks to create an even faster bobsled.

Due to the difference in the track at the Sochi Games compared to the Canadian track, Bodine knew they needed to try something different. “We knew we needed an accurate and precise 3D design that could give us a realistic and cost-effective way to test and tweak Night Train 2 prototypes. The solution was SolidWorks,” said Bodine.

When it comes to bobsledding, hundredths of a second are extremely important. At the start of the race, the bobsledders run for about 5 seconds and can get up to speeds of over 25 miles per hour.

Watch the Bo-Dyn bobsled team explain how important their head engineer is to their success.

The Bobsleigh Four-man competition at the 2014 Sochi Winter Olympics will be held on February 22nd and 23rd. We will have to wait and see if Bo-Dyn and Night Train 2 bring home the gold medal!

3D Printing for Pinball Wizards

February 13th, 2014

I grew up an arcade junkie.  If I had money in my pocket, I couldn’t wait to get to the nearest video game or pinball machine.  I remember when the best video games were in arcades, not something you connected to your television at home.  Which leads me to write about using 3D Printing technology to repair a bit of nostalgia.

My good friend Stuart, an Associate Professor of Communications at the University of Louisville, approached me with a problem during a round of golf.  One of his vintage pinball machines, a wondrous solid-state link to my youth, had broken.  Not the entire machine, just a piece of plastic that separates two possible paths for the pinball to travel.  As you can imagine, replacement parts for old pinball machines are not something you pick up at a local store.  So last fall on the 19th hole – that means drinking a beer to you non-golfers – Stuart handed me the broken piece and later sent me a picture of where it went in his pinball machine.

2014-0212a Broken part reference

I began by scanning the broken off plastic next to a ruler.  Using SolidWorks, I inserted the scanned image into a sketch of a new part.  I then resized the sketch picture to use as reference.  With the broken part, the scanned image, and the picture, I had everything I needed to create the replacement piece.  Other than having to make a few guesses about the metal standoffs for a secure fit, the solid model was fairly simple to generate.  The key aspects of the design are the slot cutout on one end for adjustment and the split U-shape for wrapping around the standoff posts and capturing the end of the still attached plastic.

2014-0212b - First SW Part Design

With my design completed, I used a Mojo Desktop 3D Printer to build a prototype.  I built up the sides a bit to help withstand the impact of the pinball into the part.  As a self professed Pinball Wizard, I didn’t want to chance the part breaking shortly after installation.  That would be like three fast drains after you start your game.

2014-0212c Initial Printed part

Other than time, like golf season when I started and Christmas season when I saw Stuart again, it was time to try out the repair kit!  One evening on the way home from work, I stopped by to visit Stuart and help him with the 3D Printed repair part install.  The installation process took about twenty minutes.

2014-0212d - Initial Part Installation

As you can see, I missed a little bit on the diameter of the metal standoffs, causing one side of the part to flare out into the path of the pinball.  While this was easily fixed with an exacto knife, I did revisit the design and build a second prototype.  The second prototype was installed on a Sunday during the NFL Divisional round of playoffs.  I recall it well as I scored one of the highest games that a guest has played on that machine!

I did learn and confirm a few things while creating this 3D printed repair part.  First, pinball games are still great fun!  Second, a picture and a broken part are enough to repair a pinball machine.  (At least this one.)  Third, I have found a new business opportunity for a budding entrepreneur!  In closing, while my normal tagline is ‘go make your products better with SolidWorks Simulation’, this time I’ll go with ‘now go make your product on a 3D Printer’!

SolidWorks Electrical: From 10 minutes to less than 3 seconds

February 6th, 2014

One of the best benefits of using SolidWorks Electrical is not having to worry about using multiple software to do what you need to do. For example, an electrical designer needs to design a 3-phase motor starter system. He would first have to create a schematic, look up part information, manually update the text, then finally stumble through a long spreadsheet to update the changes he made. This process takes a lot of time and is error prone. Whereas, if the same designer were to use SolidWorks Electrical, he would not have to worry about the manual work. Now, the engineer has more time to spend designing, rather than manual work.

The total time and money saving is tremendous when adding everything up at the end of the day.

This video shows a sped-up typical process of designing and documenting an electrical system using a regular 2D CAD software, then compares it to using SolidWorks Electrical.

What Can’t You Design In SolidWorks? #3

January 28th, 2014

RC Hovercraft #3 – SolidWorks Simulation

To review, I had 4 main design criteria for the Remote Control Hover Craft.

  • Utilize the SolidWorks and SolidWorks Simulation Suite of software to develop and optimize the hovercraft design.
  • The RC Hovercraft’s main components will be 3D Printed using the Stratasys UPrint.
  • Easy to Assemble. I want to make the assembly as easy and as straight forward as possible with concise instructions.
  • For purchased components, use low cost, off the shelf components including the electric motors, electronic speed control (ESC), batteries, and propellers.

The next step of the design process is to verify using  SolidWorks Flow Simulation  that the motor and propeller combination will provide a proper amount of air flow to lift the hover craft.

Flow Simulation provides an understanding of  flow in an internal or external volume.  Flow Simulation calculates flow with media including Gases, Fluids, Real Gases, and Non Newtonian Fluids.  Flow Rate, Velocity, Pressure , Vortices, and many other parameters are calculated during the solution.

The following  calculation with the provided manufacturer information was used to calculate the flow parameter boundary conditions for the simulation.

CFM = Cubic Feet per Minute = Volumetric Flow Rate

Mass Flow Rate = (Density) x (Volumetric Flow Rate)

Newton’s Second Law of Motion:  Force = (Mass) x (Acceleration), or F = ma

F = ma = (Mass Flow Rate) x (Velocity), given a constant flow velocity

(i.e., constant propeller speed and pitch angle).

Velocity = (Volumetric Flow Rate) / (Area), where Area = (Pi) x (r^2), the

length of a propeller blade is a good approximation for the radius, r.

Thrust = (Density) x (CFM^2) / ((Pi) x (r^2))

Note: Keep track of your units!

The hover craft’s Flow Simulation was approached from an external analysis type.  A volume was specified around the  hover craft to capture flow into the  inlet and out of the bladder, and its effect from the surrounding environment.  A fan was used to provide the draw of air through the inlet into the internals of the hover craft.  Parts of the hover craft were removed including the canopy cover batteries, and escs.  These components are unnecessary for teh flow run and would increase computational time.

The results from the Flow Simulation run show a symmetric and even outlet pattern of flow from the Hover Craft’s “Bladder”.  The parameters provided by the flow simulation suggest that the motor and propeller combination should be sufficient for lifting the craft.
