ANNOUNCEMENTS AND GENERAL BUSINESS

 

The meeting was held at the Albuquerque BioScience Center, Main Conference Room (2nd Floor), 5901 Indian School Road NE, 87110. It should be noted that some of our members work at the BioScience Center and make themselves available after work with setup help and logistics (projectors). Thanks to Nate Jones and James Hannon.  Food was from Flying Star. Drinks and desert were supplied by MCAD Thank you to all our sponsors!

 

We had over 50 attendees!

 

User-group President, William Radigan started the meeting and showed off the User Group of the Year Award which we won at SolidWorks World 2016 (Feb 1-3). It will get passed around to be displayed at our various sponsors. For now we will leave it at the BioScience Center who provides us a meeting place.

 

Taped to the wall at the back of the room were five posters, each with a different heading: 3D Printing, Plating, CNC Machining, Manual Machining, Injection Molding. Over the course of the meeting during breaks, attendees wrote the names of preferred vendors under appropriate headings. The categories and vendors are listed as follows.

SolidWorks World 2016 Recaps by NMSUG members who attended

 

RANDY LYNN’s SolidWorks World Recap

 

Each year at SolidWorks World, the SolidWorks User Group Network recognizes the User Group Leader of the Year, User Group of the Year, and awards the Community Service Award to an individual who willingly and freely shares his SolidWorks expertise with the local community.

 

  1. Out of 220 user groups, NMSUG was awarded the User Group of the Year award! This is a big deal and a testament to William’s hard work on our behalf.  [Randy wrote that, not me. J]  I think through direct contact with Marie Planchard and probably feedback from some of our visiting presenters who carry clout in the user-group community, the word got out that we are doing good things here in Albuquerque, especially in how we encourage and welcome the school robotics programs, FSAE, and that we seem to always have a contingent from NMSU in attendance.

 

Randy last attended two years ago in San Diego. They rolled out SolidWorks Mechanical Conceptual and billed it as a 2d cloud collaboration tool under a rental software license. The response was less than enthusiastic. It is still around though Randy is not aware of anyone using it but was curious to see where SolidWorks is in the cloud collaboration market, especially since OnShape and Fusion 360 are getting significant exposure in the 3D CAD market.

 

OnShape has more than 20 people on its staff with SolidWorks on their resumes. (They have 34 Interns). They have a very international staff. They offer a free account and $100/month/user account. It runs in a browser, your documents are in the cloud in a “cloud-native” format. It runs on Mac, PC and hand-held devices. Randy thinks it is multi-threaded.

 

Fusion 360 is a cloud based collaboration offering from AutoDesk, $40/month (free trial) that looks pretty amazing. The website has a link to Fusion 360 Fast Track for SolidWorks Users which is tech support with an understanding that you may be migrating from SolidWorks or another package. It is an application you install on your computer. It runs on Mac or PC. It may be multithreaded.

 

SolidWorks Xdesign and Xdrive are newly announced SolidWorks products that are installed on a cloud computer and use Frame technology to run it in a browser. Beta testing is starting soon. It will run on a handheld device. It is unclear if it is just SolidWorks installed in the cloud with a few added features. They showed it running on an iPad. He was using a pen to move it around. Xdrive is a cloud-based storage app specifically for Xdesign. You can link it to your Dropbox and other cloud storage accounts you may have. Not sure if it is multi-threaded. Also not yet clear is the cost model for Xdrive and/or inclusion with existing products like SolidWorks Professional or Premium. It is also unclear how collaboration works.

 

https://www.fra.me/solidworks right now to run SolidWorks in a browser. Beta soon, product available in the spring.

 

http://www.solidsmack.com/cad/solidworks-xdesign-innovation-platform-and-what-it-all-means/ has a diagram that illustrates the SolidWorks Innovation Platform and how SolidWorks and Xdesign fit into the bigger picture.

 

SolidWorks has significant technology and expertise they can leverage towards a Cloud-based CAD offering. The ideal solution may be if current users can choose to run SolidWorks on either platform and operate on the same files, back and forth as circumstances and convenience permit.

 

DAVID SAMUEL’s SolidWorks World Recap

 

David wanted to learn as much as he could about MBD (Model Based Definition). He attended nine breakout sessions that covered various aspects of MBD. Sessions included MBD basics, the paperless office, interactive 3D pdfs with drawing-like information (not necessarily for printing). If you are not familiar with MBD, below are some recap notes from the June 10, 2015 user-group meeting in which John Milberry, SolidWorks Area Technical Manager spoke specifically about MBD.

 

Model-Based Definition, or MBD is used to eliminate paper drawings from design and manufacturing. Drawings traditionally are used to convey design intent to manufacturing. The US Department of Defense published MIL-STD-31000A which outlines the MBD protocols and requirements for technical design packages. It is intended to automate, reduce errors, and improve communication throughout design and production.

 

SolidWorks MBD is a SolidWorks add-on that combines existing SolidWorks dimexpert functionality with additional features and functionality to generate eDrawings and 3D pdfs that convey Product Manufacturing Information in accordance with MIL-STD-31000A.

 

MBD is a separate SolidWorks product. In addition to the Dim Expert functionality, SolidWorks MBD adds 3D Annotations, Geometric Dimensioning and Tolerancing, Bills of Material functionality, and 3D Dynamic Model viewing.

 

David also mentioned a large assembly tip he learned in one of his sessions. There are two Image Quality sliders (Options>Document Properties) sliders: Shaded and draft quality HLR/HLV resolution and Wireframe and high quality HLR/HLV resolution. For each, the left end is labeled Low (faster) and the right end is labeled High (slower). At the right end, the last 10 percent of the slider is the “Red Zone.” Many of us thought these sliders related to curvature appearance on our screen. We thought if we had a good graphics card we could move the sliders more to the right. It was demonstrated that a model saved with the sliders to the right consumed more disk space than a model saved with the sliders to the left. In the context of a large assembly with lots of cylindrical parts (fasteners) this difference manifests itself in load times and overall large assembly below. There is more…read Dave Fury’s comments below.

 

Lastly, David mentioned a product that was profiled on the big stage at SolidWorks World. It was a better bra from a company named TRUSST Lingerie. David Pogue (New York Times technology writer and Yahoo blogger) interviewed two female engineers who used SolidWorks, including Simulation, to design a better bra. Aside from some good-natured humor, the profile was fun and inspiring. The lesson is that just because a design has been around for 100 years does not mean it is fully-evolved. With creativity and the right tools, we CAN innovate on the status quo. The Trusst founders profiled their SolidWorks World experience on their website.

DAVE FURRY’s SolidWorks World Recap

 

This was Dave’s second SolidWorks World. Dave’s employer asked him to learn and research as much as he could about SolidWorks PDM Standard which is replacing Workgroup. Unlike David Samuel and MBD, there weren’t many sessions that talked about the new PDM Standard. Time to put MCAD on speed dial.

 

Dave relayed a report from the Monday session where SolidWorks indicated they may have a flex module/licensing plan in the future.

 

Dave also mentioned the Image Quality settings to which David Samuel referred to above. After learning this, Dave and NMSUG member/coworker Wayne Meagher spent a couple of days actually opening assemblies, moving the Image Quality sliders to the left, and saving them. They have since noticed a savings in disk space and faster opening and manipulating of models.

 

WILLIAM RADIGAN’s SolidWorks World Recap

 

Zemax lens mechanics is a new SolidWorks Add-On. In his work, William has been on the receiving end of Zemax generated STEP files and which he had to incorporate into his SolidWorks designs. He is excited to start using this add-on with his clients. William maintains Zemax’ $2000 price tag is well worth the time it will save him in addition to a cost savings for his clients.

 

The partner pavilion featured many 3D printers. Most notable may be the Sindoh-3D Printer, 3Dwox DP200, cost $1000. It comes with a .4mm nozzle, layer height goes down to .05 mm. This seems like a real good value in a printer.

 

Alin Vargatu’s Custom Property Presentation: WOW! This was a very good hands-on session. Did you know…

  • A custom property can drive an equation
  • A custom property can drive an annotation
  • A custom property can color code components

 

MORE TO COME! This presentation was so good, we plan to try to make it available to our group perhaps live with Mr. Vargatu or it may be something we put on ourselves with his notes.

 

SolidWorks Visualization is the result of the SolidWorks acquisition of Bunkspeed. It is better rendering than PhotoView 360. If you have a Premium license then you can download it right now.

WILLIAM RADIGAN-How to Take Full Advantage of SOLIDWORKS Motion Analysis Data

 

William is our user group President. He is a PE and has had his own company, Radigan Engineering, since 2006. William’s presentation is How To take Full Advantage of SOLIDWORKS Motion Analysis. This presentation will discuss how SOLIDWORKS Motion Analysis can be used within the design process to efficiently reach machine performance goals. It will also show how simulation results can also be used for comparison to measured values or numerical post-processing.

 

SWX Motion is a shortcut to a college level ME303 Dynamics course that is available right in SolidWorks. SWX Motion uses the MSC ADAMS solver inside of SolidWorks.

 

  1. First make sure to ‘check’ the “SOLIDWORKS Motion” Add-In under Tools à Add-ins (Unfortunately, it’s only available in SW Premium. L)

 

Tips for using SWX Motion-If you know your assembly is destined for Motion Analysis…

  • Keep your FMT short
  • Flexible Subs work but be wary
  • Avoid Flexible Subs of Flexible Subs

 

Limit Mates are infinitely stiff at their boundaries

 

Observe your assembly tree. The position of assembly components are indicated by

  • over defined-BAD for Motion Analysis
  • under defined
  • (?) not solved
  • (f) fixed (locked in place) IS NOT THE SAME AS FULLY-DEFINED

 

Remove Redundant Mates-The goal is to reduce the number of redundant mates and make the model easier to solve.

 

SolidWorks mates are copied into the motion study. In Motion, some of the mates need to be softened (built-in slop based on bushing properties).

 

You can also add local mates to the motion study. They exist in the motion study only and will not appear in the SolidWorks Feature Manager Tree.

 

Fix the rotation on fasteners and similar connections. This reduces the degrees of freedom in the system and simplifies the motion analysis.

 

The goal of this project was to build a mechanical arm to mimic a known acceleration.

 

In William’s example, he needed a pair of concentric mates at each end of a shaft (otherwise it would be a perfectly rigid cantilever. While it looks OK, it does not mimic reality.) The “cantilevered” shaft is infinitely stiff. Employ a hinge mate instead of a coincident/concentric mate THEN in motion, apply a bushing along with its catalog properties to the hinge mate to more accurately model the non-rigid motion.

 

In motion, you can use the motor tool to apply a rotation to a part. You can define the motor’s angular velocity and acceleration.

 

Use the Motion Study Properties to define the motion analysis.

 

With motion, you can pick a point on your motion model and use the Trace Path option to generate a motion profile. You can export that data (x, y, z) to a csv file and show it in Excel.

 

Using the Results property manager, you can generate any number of plots, each with their own properties, to show displacement, velocity, and acceleration of your trace point. You can mask plots onto each other. Editing functionality lets you title the plot and name the axes, and the names you use will become the column headings in the exported CSV file. He also demoed how to use the Results dialog to show the reaction forces.

 

Within the Motion Study Properties…

                GSTIFF is constant time steps for continuous motion, solves quickly

WSTIFF is for discontinuous motion such as a bowling ball striking a pin, variable time steps and solves slowly.

 

Ultimately, William was able to create a linkage the mimicked the acceleration plot from his customer.

 

QUESTIONS: Can you use this to look at the stall torque. Don’t think so.
