SolidWorks User Group - Kansas City

Kansas City SolidWorks User Group


On June 27th, I attended and presented at the
KCSWUG meeting hosted by MRI Global.  My
topic was presenting some of our findings with regards to making SolidWorks
perform with hardware sized for your SolidWorks models.  Also at this meeting we saw a presentation
from SolidWorks employee, Richard Allen. 
Richard is a Product Portfolio Manager for SolidWorks Corporation.  His role consists of “acting as the voice for
the customer” which means he tries to do the following:



  • Work with product enhancements

  • Increase performance and quality

  • Innovate new products


Richard also spoke of a new 3D Dimensioning standard on part
models to reduce printed or 2D drawings. The US government is already using
this for Military contract suppliers. 
This new methodology is estimated to save 28% of scrap due to better
understanding of dimensions on the 3D Model. 
Did you know that SolidWorks has had 3D Model Dimensions since
SolidWorks 2008 in the form of DimXpert? 
DimXpert for Parts is a set of tools you use to apply dimensions and
tolerances to parts according to the requirements of ASME Y14.41-2003 and ISO
16792:2006.


We also talked about obstacles that the group would face
trying to “do away” with 2D printed drawings. 
Several members agree that this would be strange in that most like to
write on drawings and this would not be possible on a screen image.  How would shops afford monitors, tablets and
other viewing devices for the production floor staff to view your models
on?  Just getting around the fact that we
like to hold and touch a drawing and use pencils or pens to write on them will
be strange.


Richard also mentioned that SolidWorks 2014 will ship
sometime in the October 2013 time frame. 
Beta 2014 is now open for registration. 
We urge all users to sign up for this, and try 2014 BETA on a separate
machine for testing and playing around.


SolidWorks has reached another huge milestone.  Over 2,000,000 users of the product now
worldwide!  Some schools across the globe
are placing SolidWorks educational software on student’s machines as young as 7
or 8 years old!  Can you believe that?  Customer satisfaction for SolidWorks products
has increased 5% since 2007, and is now close to 94% approval based on mailed
out surveys. 


Richard also demonstrated the new eDrawings Pro application
on his iPad.  This has the new Augmented
Reality feature which allows you to display your SolidWorks models using
eDrawings, and the camera function from your tablet to place virtually your
models in the room or environment seen by your camera!  Very cool technology.  These App’s run $2 or $10 from the Apple Store.


Check out this video for more information: http://www.youtube.com/watch?v=rVcIaBAQSE4


For a stormy Thursday night we had a pretty good turnout and
the food is always great.  If you get a
chance to come next time, the meeting will be sometime in September and the
user group web site is http://www.kcswug.com/main/


Hope to see you there!


Thanks,

How Stratasys' FDM 3D Printing Technology Works

Graphic of print head extruding a thin bead of plasticFused Deposition Modeling (FDM) Technology is a powerful Stratasys-patented additive manufacturing method.


FDM builds concept models, functional prototypes and end-use parts in standard, engineering-grade and high-performance thermoplastics. It’s the only professional 3D printing technology that uses production-grade thermoplastics, so parts are unrivaled in mechanical, thermal and chemical strength.


The Invention of FDM Technology


Stratasys founder Scott Crump invented FDM Technology more than 20 years ago, and Stratasys has continued to lead the 3D printing revolution ever since, developing a range of systems that appeal to large manufacturers, designers, engineers, educators and other professionals.


How FDM Works


3D printers that run on FDM Technology build parts layer-by-layer by heating thermoplastic material to a semi-liquid state and extruding it according to computer-controlled paths.


FDM uses two materials to execute a print job: modeling material, which constitutes the finished piece, and support material, which acts as scaffolding. Material filaments are fed from the 3D printer’s material bays to the print head, which moves in X and Y coordinates, depositing material to complete each layer before the base moves down the Z axis and the next layer begins.


Once the 3D printer is done building, the user breaks the support material away or dissolves it in detergent and water, and the part is ready to use.


FDM Benefits


FDM is a clean, simple-to-use, office-friendly 3D printing process. Thermoplastic parts can endure exposure to heat, chemicals, humid or dry environments, and mechanical stress. Soluble support materials make it possible to produce complex geometries and cavities that would be difficult to build with traditional manufacturing methods.



What happened to my SolidWorks Add-ins?

Premium Add-Ins


We recently had a customer who has a SolidWorks Premium license but did not have any of the Premium add-ins. The customer installed and launched SolidWorks. It even launched as SolidWorks Premium but did not have any of the add-ins. (Picture below is what SolidWorks Premium Add-Ins should look like)




I have seen this issue before and it is fairly common. The most likely cause of this is the add-ins were turned off during the install by accident. To get your add-ins to show up is pretty simple. All you have to do is go and modify the installation.


You go to Start, Control Panel, Programs, Programs and Features. Select SolidWorks and select Change.




Once you select Change, the SolidWorks Installation Manager will launch. Select Modify the Installation.





Click Next. Click Next when you get to the Serial Number screen. SolidWorks will go to the System Check screen and then to the Product Selection screen. When on the Product Selection screen you need to expand SolidWorks and select the Add-ins you want added.




All you need to do is select next through the installation and then launch SolidWorks and you should then have all of the add-ins.

How Stratasys' Polyjet 3D Printing Technology Works

PolyJet Print Head DrawingPolyJet 3D printing is similar to inkjet document printing. But instead of jetting drops of ink onto paper, PolyJet 3D printers jet layers of liquid photopolymer onto a build tray and cure them with UV light. The layers build up one at a time to create a 3D model or prototype. Fully cured models can be handled and used immediately, without additional post-curing. Along with the selected model materials, the 3D printer also jets a gel-like support material specially designed to uphold overhangs and complicated geometries. It is easily removed by hand and with water.


PolyJet 3D printing technology has many advantages for rapid prototyping, including superior quality and speed, high precision, and a very wide variety of materials. Based on PolyJet technology, Objet Connex 3D Printers from Stratasys are the only additive manufacturing systems that can combine different 3D printing materials within the same 3D printed model, in the same print job.


3D printed plane combines multiple materials in the same partThe Only Multi-Material 3D Printing Technology



Objet Connex 3D Printers feature unique technology that can jet multiple materials in a single print run. This means that you can selectively position multiple materials in one printed prototype and even combine two materials to create composite digital materials with distinct, predictable material properties.


With more than 100 materials and digital material combinations to choose from, including rigid to rubber-like, opaque to transparent and ABS-simulating performance, the sky is the limit. More than ever, your prototypes can match the look, feel and function of the most complex end products.


Model car 3D printed with multiple materialsPolyJet 3D Printing Benefits


PolyJet technology creates precision prototypes that set the standard for finished-product realism. Its very thin print layers make complex shapes, fine details and smooth finished surfaces possible. Objet Connex 3D Printers offer more material versatility than any other technology, including the ability to print multiple materials simultaneously.

How Simple is Too Simple??

When doing simulations, time and accuracy are both very
valuable.  Using different configurations
is a good way to balance the two.  As
always though, there are trade-offs from going too far either way.  Too much simplification can mean widely
incorrect results while too little can lead to negligible decrease in time.


 
Wing


In this example, a wing was created with three
configurations;



Ribbed


ribbed,



Hollow


hollow



Solid


and solid.


A fixed geometry was added to the wing edges where it would
attach to the airplane body and a force of 25000 N was added coming from the
front at an angle of attack of 5.5°.


 






























Configuration



Time



Stress



Displacement



Ribbed



33 sec



6.2 Mpa



8.93 mm



Hollow



5 sec



6.6 Mpa



10.1 mm



Solid



2 sec



2.9 Mpa



3.78 mm



As shown by the results above, while the differences in
stress and displacement between the ribbed and hollow configurations are small,
the gains in time spent in calculations are large.  Conversely between the hollow and solid
configurations, the time gained by this simplification is small and the
differences in stress and displacement are large.  While the times in these simulations are all
small, more complex parts and assemblies will take longer and simplified
configurations will help to decrease the time spent and memory used.  As long as they are not oversimplified,
simplified configurations become very useful.

SolidWorks Modeling Methodology - Part 1

CATI's monthly contribution to the SolidWorks Blog was posted this week. This month I chose to write about proper modeling methodology for SolidWorks, this is part one of a two part set of articles. The reason for writing this article is because after working with so many customer files we have learned the one item that is not taught in any training class is proper modeling methodology. This first article talks about all of the different items we need to look at and evaluate before we create a model in SolidWorks. The second article is going to look into reverse engineering the part show below and finding what features and sketch options will allow us to build the most efficient model. If you have any ideas or suggestions please post those as comments to this article and I will try to use as many of those ideas that I can.

Hockey puck key chain

You may have heard the local hockey team has advanced to the finals. As a tribute I decided to print out a keychain using a Stratasys Objet30. I modeled the hockey puck in SolidWorks. The final dimensions used were 1.5inch diameter by .33inch height. I started with a cylindrical extrusion with some fillets on the top and bottom.



Hockey1


The next challenge was the knurl pattern around the side. I created a helix feature between the fillets to use as a path for my cut sweep. Then a triangle sketch was swept cut along the helix.



Hockey2


To create the final knurl pattern the cut sweep was circular patterned so the edges would come as close to touching as possible but not overlap. This gave me a pattern in one direction. It just needed a mirror for the other direction.



Hockey3


Finally i removed material from the top to show the logo and cut a hole through the part to make it into a keychain.



Hockey4


The fine level of detail on the 3d printer did a great job on the logo and knurl pattern.

How to Insert Dowel Pin Holes in SolidWorks

Many SolidWorks users, especially woodworkers, have asked for this enhancement for awhile: Have the ability to define a hole as a dowel pin hole in the part and have it automatically insert a dowel pin symbol in the drawing.


Dowel_pins


Starting in SolidWorks 2013, users now have the ability to add dowel pin holes. (Applause!) Dowel holes are used to align components in assemblies. Standard dowel holes have been added to SolidWorks in the Hole Wizard. So, all you need to do now is to click on Hole Wizard.  In the Hole Specification PropertyManager, on the Type tab, click the Hole button under Hole Type. In Type, select Dowels. SolidWorks gives you standard diameters to choose from or you can assign custom diameters appropriate to your industry. Fit options are also available. Set options as needed. That’s it!


Hole_dowel


Now that we have added dowel holes to the SolidWorks part document, let’s take a look at the drawing. There is a new document option for the automatic creation of all dowel pin symbols on view creation. Go to Tools > Options. On the Document Properties tab, click Detailing. Under Auto insert on view creation, you can select either Dowel symbols -part or Dowel symbols -assembly. Then, click OK.


Detailing


Additionally, you can automatically insert all dowel pin symbols in a SolidWorks drawing view after view creation. You can automatically insert dowel pin symbols for dowel holes created with the Hole Wizard. To automatically insert dowel pin symbols into a drawing, pull down the Insert menu and pick Annotations > Dowel Pin Symbol. Under Auto Insert, select For all dowel holes.


Dowel_pin_symbol


As you select the drawing views, the dowel pin symbols are inserted in the view. Note that you have the ability to flip a dowel pin symbol after it has been inserted (right-click the symbol and click Flip Symbol.)


Lastly, to manually insert dowel pin symbols into a SolidWorks drawing, pull down the Insert menu and pick Annotations > Dowel Pin Symbol. Select a circular edge, a sketched circle, or an arc. Note that you can pre-select your circular edges, sketched circles, or arcs and then click Insert > Annotations > Dowel Pin Symbol. Dowel pin symbols appear in the selected holes.


Although this Dowel pin feature in SolidWorks is great, there are some improvements already requested like:


The ability to define a dowel pin hole tolerance by either the hole or the pin.
Add functionality to insert dowel pins
Ability to add Dowel Pin symbol to a point, not just circular edge or arc

Mirror, Mirror, Where's my sheet metal notes?

So many of us have had the opportunity to make mirrored sheet metal parts. Over the years the process has changed and we are pretty close to having it all. However we still see a snag here and there with the drawings for these neat tools.


On the mirrored sheet metal part, if you choose to keep the link in the model you can't get your notes on the drawing. If you break the link you can get all your features and then create a new flat blank, but then it's not updating on it's own. So what can we do?


I have created a workaround mirrored sheet metal part to make both updating and sheet metal notes work on the drawings.


Since the sheet metal notes are created with the flat pattern view we need to have 2 of them. A good way to do this is to duplicate the sheet metal bodies and not the whole part.


Here we see the whole tree, let's break it down.



Internal1


 


First we have rolled it back to look at our steps.



Internal2


 


I created a mirror feature and chose the bodies to mirror option.



Internal3


 


Then I deleted the initial body. (don't worry we get that back later)



Internal4


 


I then created a derived configuration of the initial sheet metal part, this way the mirror will update when the initial body does. In the initial confiugration the mirror and the delete body are suppress. In the mirroed configuration the mirror and delete body are unsuppress. Then I used a drawing to insert a flat pattern of each configuration so that those flat patter configurations were created. The flats are important to get the sheet metal notes.



Internal5


 


On the drawing you can now see all of the bent and flattened states of the part.



Internal6


This may be a little on the long side but it works until the SPR is finished and we have the new controls to work with.

Where's the center of mass?

Recently I have had customers asking for a way to add a center of mass point to their drawing so they can dimension to this point.   This is now possible in SolidWorks 2013 using the Center of Mass function.


To use this function, you must turn on this function in your part or assembly.  To do so, go into the
mass properties window and check the option “Create Center of Mass Feature”.



Mass properties window


This will create a Center of Mass feature in the Feature Tree just below the origin.



Center of mass feature tree

To access this point inside of your drawing file you will need to go to Insert, Model items and check the option for
Center of mass symbol Center of Mass under the Reference Geometry section.



Insert model items center of mass


You will now see the center of mass point on the drawing.  This can be dimension to, and will update as the model changes.



Drawings showing center of mass


Hope this helps you out.

Free SolidWorks from Performance Constraints (FSWPC-13-#21)

Optimal Configuration & Conclusion


In looking back at the past 20 articles we have posted about Free SolidWorks from Performance Constrains one of the items we promised in our first article was to give you the two optimal configurations that gave us the best overall performance.


Before we get to the results lets recap what we tested in our previous articles:



  • RAM

  • Processor Clock Speed

  • Number of Cores and SolidWorks

  • Hard Drive Speed

  • Graphics Cards

  • SolidWorks files stored in an older version

  • Windows Visual Settings

  • SolidWorks Options Set to Optimal

  • SolidWorks Image Quality

  • SolidWorks RealView Graphics

  • Level of Detail in Parts and Assemblies

  • Reducing Top Level Mates and Solving Subassemblies as Rigid

  • Defeature

  • Envelope

  • Large Design Review

  • SpeedPak

  • Save Assembly as Part (3 options)

  • Large Assembly Mode & Lightweight


In the list above you want to take note that of the 18 items we tested 13 of them are FREE.


The first scenario that we tested included all of the performance improvements explained above except Large Assembly Mode and Lightweight options. The environment looked like this:


Typical and Practical Hardware configurations


Configuration



  • SolidWorks Options Optimized

  • OS visuals set to best performance


Modeling methods



  • Level of detail reduced

  • Image quality reduced

  • Realview Graphics off

  • Top level mates reduced




In our first test the combination of the enhancements to our SolidWorks environment yielded some impressive performance results.


If we take all of the settings and hardware listed above and add in Large Assembly Mode and Lightweight we can see that it has even more of an impact in our results.




You can by looking at our deltas see that on our Practical machine we gained over 76% total improvement taking our benchmark run time down to just over 18min. If we look at the Typical machine we can see that the overall improvement is almost a 90% performance gain and our benchmark run time has gone from 4:43:44 to 0:28:50.


Conclusion


What we have found in our efforts conducting these tests is that improvement of a modeling environment must be approached at a system level rather than a specific component level. All of the hardware, configuration, and modeling methodology options work in concert to establish the performance capabilities of a workstation whether it's good or bad. Adding more processor power to a workstation that is short on RAM will help. But the improvement that the stronger processor yields will be much greater if RAM is added as well.


Understanding these several aspects of a SolidWorks modeling environment and how they work together can make all the difference in ensuring that you get the full value from your hardware and software purchase.


Adrian and I plan on continuing our testing for the next SolidWorks World in 2014 so please keep checking back for updates. We are planning on creating some new tests and new ways to display the results. If you have any suggestions please add a comment to this or any of our other articles.


Please
check back to the CATI blog as we will continue posting our
series of articles that goes further into the details of each of our tests. All
of these articles will be stored in the category of Free SolidWorks from Performance
Constraints
 and links to each with their
release date are listed below:

FeatureManager Design Tree "Flat Tree" option - New for SolidWorks 2013

SolidWorks 2013 has 2 new FeatureManager Design Tree features. In my May Blog, I highlighted the Feature Manager Design Tree "Favorites" option. The second new feature is the Feature Manager Design Flat Tree option.


The FeatureManager Design Tree View allows
the user to show a "Flat Tree" option. a Flat Tree is where the
features are shown in the order they were created, instead of hierarchically.
In a flat view, curves, 2D sketches, 3D sketches are not absorbed into the
features that reference them.


Note: the Flat Tree View is only for parts and the following items
are unabsorbed in Flat Tree View:



  • Simple
    hole

  • Hole
    Wizard holes

  • Mounting
    boss

  • Lip/Groove

  • Snap
    hook groove

  • Vent

  • Snap
    hook

  • Vent

  • Snap
    hook

  • Sheet
    metal feature

  • Library
    feature

  • Weldment
    structural member

  • Sketch
    block


Here's how it works:


Right mouse click on the part name in the FeatureManager DesignTree. In the pull down menu, go to Tree Display and click on Show Flat Tree View.



1


Below is the FeatureManager Design tree using the Flat Tree option:
