BM logo - your choice in Rendering

Posted by VladimirPalffy Jul 19, 2012

Wallpapers for you - BM (created with Creo Parametric)






So after a mere three posts in my own private blog "The Zone", I'm moving the blog! I asked Dan Marotta whether I could keep my private blog and have it appear under the new Cabling, Piping, and Schematics sub-group, too. Apparently it has to exist in one place or the other- but not both.


In the interest of reaching more people, I'll submit all new blog posts under the new Cabling, Piping, and Schematics group. I'll keep The Zone open for more personal items (like perhaps if go on a mini rant, I'll post it to The Zone).  The goal of starting a blog was always to create a forum for discussing routed systems topics. Now that we have a great new space, I'll dedicate my time to filling it with relevant, timely information, tutorials, videos, and training material.


To that end, I've been working on a new video to post to the cabling forum. I've been spread a bit thin this past week finishing up course work and taking final exams. I hope to have the new video and an "enhanced" version of my Ninja Cabling presentation ready for upload within the next few days.


In the meantime... please check out our new group using the links above.  Be sure to follow the new group to insure you'll receive the latest updates and postings as they're submitted!


From the ashes of the defunct MAPUG (Mid-Atlantic PTC Users Group) and the VA/DC area user's group, we're launching a brand new RUG- the Chesapeake Regional Users Group (CPUG).


This group will focus heavily on the Creo (ProENGINEER) and Windchill PTC products. Multiple meetings will occur each year with the first beginning in Fall 2012.


So what happened to the old groups? In my personal opinion, the previous RUGs in the mid-Atlantic region suffered from a severe case of "mission creep". Meetings lasted for hours on end and served no purpose other than as an extended sales pitch and a cash grab. At the last MAPUG meeting I attended, I paid admission at the door. This was followed by a torturous 2 hour demo of Wildfire 4 and 5 given mostly via an endless powerpoint slide deck. Eventually I was let loose to grab lunch but in the lunch area I was literally surrounded with vendors on all sides. After lunch, I gave a brief presentation and then sat down for another long demo and then finally... one more long demo. In the end, I took nothing from the meeting... and left about about $20 poorer. The meeting had no actual value to me as an engineer.


I can promise CPUG will not devolve into one long extended sales pitch. We'll focus on networking, practical tips, techniques, and training. At each and every meeting, we will provide value to the user community. When members leave a CPUG meeting, they'll go back to work with real, tangible, useful information to make them more efficient and better prepared to meet the demands of their job.


If you're in the Baltimore/Washington/Philadelphia area, please consider joining our group. Follow the CPUG group on Planet PTC Community by selecting Join This Group from the panel on the right hand side of this page. Feel free to respond to the blog with questions or comments.


As meeting dates, times, and locations firm up, they'll be posted here and announced to members via email. I expect some growing pains as we get the group off the ground. If you'd like to join the cause and help establish the group... please email me.


Thank you!



Once upon a time, back when PTC was still Parametric Technology Corporation, the company had only one product- Pro/ENGINEER. It looked like this...




Back in those days, users who wanted to learn more about the software had few options. They could read the printed user manuals or fiddle with the software until they figured it out. Eventually these pioneers of the parametric modeling frontier formed small groups. They'd meet in libraries, schools, local pubs, or other small venues to discuss modeling techniques, share tips and tricks, socialize, and learn from each other. This was the way Pro/ENGINEER User Groups formed and grew into dozens of larger Regional User Groups (or "RUGs").


RUGs sought to deliver on a core mission: Gather people. Share knowledge. Benefit the user community. For years, they thrived... but now they're on a definite (and rather steep) decline. So what happened?


In my opinion, it comes down to a simple truth that many of the groups strayed from their core mission. Over time, many RUGs simply disappeared. While we can debate the reasons why this happened, identifying the problem surely does nothing to solve it.  We need new leaders, industry support, and community involvement to start new groups committed to sharing knowledge and serving those who use PTC software.  Not to mention, we need a whole lot less of the indifference, condescension, and apathy that killed off many RUGs.


While I realize that vibrant, active, and thriving RUGs still exist, they're getting tough to find. If anyone takes exception to this assertion, I challenge you to search for them. You'll find under two dozen active groups in the entire United States. Conversely, performing a similar search of SolidWorks User Groups turns up almost as many (18) just within 100 miles of my house. I'd have to drive for over 250 miles to reach the nearest active Pro/ENGINEER RUG. This is unacceptable!


So what are we going to do about it?  Well... I'm just one guy but I'm rather tired of not having a user group. The last two in this region (Maryland/DC/Southern PA) went completely defunct a few years ago. So, I'm just going to start a new one! After kicking around name ideas for several days, I just decided to go with CPUG (for Chesapeake Regional PTC Users Group). I'll be sending out individual invitations to every company in the area and every individual contact I have. Our first meeting will be Fall 2012 (location to be announced).


I'm confident a new RUG can be successful if it stays true to the core mission of sharing knowledge and providing a benefit to PTC customers and individual users. With luck and the helpful support of others in the region, we'll do just that.

Planning a summer break? in PTC Live Global

Posted by msimon Jul 16, 2012

I know that during this time of year, many people are planning their summer vacations (including me). If riding your bike is how you like to spend your free time, I encourage you to watch Joe’s Graney keynote from PlanetPTC Live Orlando before you lock the door of your office for 1, 2 or 3 weeks (if you are so lucky).


In his presentation, Joe showed us that training, passion and desire to win exist not just in racing field but also in the offices where these first-class bikes are designed, tested and manufactured. From its headquarters in Santa Cruz, California, which as Joe says, look more like a car garage, Santa Cruz Bicycles develops the highest performance mountain bikes in the world.


If you couldn’t attend Joe’s keynote live, now you have the opportunity to watch the recording. In this keynote, Joe confesses that “Bikes saved my life.” Maybe that’s too melodramatic, as he recognizes, but the truth is that bikes heavily influenced the way he is today. When watching this recording, you’ll feel the passion he puts into his work and his desire to excel. After watching it, you may want to share your passion for life with us and what influenced the way you are today. We look forward to hearing from you.


Enjoy your summer break!




If you've visited the Creo Community today, you may have noticed two new additions to the line-up; a Rendering Community and a Piping, Cabling & Schematics Community.


Use the Rendering Community to learn the techniques of rendering your models or show and tell how you use Creo models in rendering. Feel free to discuss ARX (advanced rednering extension), external render applications and techniques for converting Creo models.


The Piping, Cabling & Schematics Community is for all your routed systems needs. Whether its techniques, tips or shortcuts, share and discuss them with fellow members.


Probably the most common performance adjust needed for Windchill systems is the adding of more memory for Oracle.  In memory access of Oracle blocks can be a 100 000x faster (fig #3) than retrieving from disk making the ensuring that Oracle is properly configured critical the overall health of a Windchill system. Having 'enough' memory will give the system the opportunity to generally perform well at the database level, although not all SQL statements will run quickly enough even when there is enough memory available.


How do you know if Oracle has been allocated enough memory for acceptable performance or your system is in need of tuning?  The SQL below can be run from SQL*plus as the Oracle 'sys' or 'system' user and will output recommendations based on rule of thumb guidelines.  If you are in doubt or have questions, opening a technical support case with the Windchill performance group and including either an AWR report, the output from gather_info_script, or System Configuration Collector (Windchill R10+) is the next step.




select name, block_size, ESTD_PCT_OF_DB_TIME_FOR_READS,


when (ESTD_PCT_OF_DB_TIME_FOR_READS >0 and ESTD_PCT_OF_DB_TIME_FOR_READS <10) then 'system is well configured'

when (ESTD_PCT_OF_DB_TIME_FOR_READS >10 and ESTD_PCT_OF_DB_TIME_FOR_READS <20) then 'system is ok but could benefit from memory and SQL tuning'

when (ESTD_PCT_OF_DB_TIME_FOR_READS >20 and ESTD_PCT_OF_DB_TIME_FOR_READS <40) then 'system is struggling, stability and performance are likely problems'

when (ESTD_PCT_OF_DB_TIME_FOR_READS >40) then 'system is under duress and immediate actions to tune the system are required'




If the memory needs to be adjusted this will usually mean in 11g increasing memory_target and memory_max_target settings and restarting Oracle ( if memory_max_target has been increased).  Adjusting adjusting Oracle 10g memory or when the sga_max_size is set to a non-default value complicates things a good explanation of these parameters can be found here


A note of caution, whenever possible do not set the sga_target parameter to zero, but this only recommendation only applies when an sga_max_size value has been specified i.e. some value other than '0'.  If sga_max_size=0, then setting sga_target=0 is also appropriate.  When Oracle sees a sga_target of zero (regardless of the memory_target setting) it appears to try and shrink the SGA to be as small as possible, flushing SGA blocks from memory more aggressively than is desirable and harming performance.  It is not clear if this same behavior occurs when memory_target is set to zero also, but it probably does.

Got a great Mathcad story to share? Interested in showcasing your Mathcad chops? Consider this to be your official invitation to present your expertise to your peers.


We have select opportunities for presenters – we’re looking for Mathcad Champions – for a variety of slots. New Mathcad users and longtime experts have repeatedly told us that they find peer-to-peer presentations extremely valuable. Our presenters benefit too, from creating new networking opportunities to establishing themselves as thought-leaders in their organizations and industries.


Right now we have openings for brief monthly webinars as well as 45-minute speaking slots at PTC’s Mathcad Virtual Conference scheduled for autumn 2012.


If you’re a Mathcad Champion, or want to become one, email us at and tell us:

  1. Your idea or topic for your presentation
  2. What your audience would like about it
  3. Your discipline and industry
  4. Your Mathcad skill level (novice, intermediate, expert)


If your idea is selected by the Mathcad team, we’ll work with you to help develop your presentation.

We know there are tons of great Mathcad stories out there. Tell us yours!


Things are heating up here in the Central Valley, and not just the temperatures (108 today ).


FIRST Team 3970, the Duncan Dynamics, has recovered from an amazing rookie season and is meeting weekly.  Their getting new members up-to-speed, practicing for upcoming presentations and of course, training on PTC tools.  We'll be looking into Windchill for project planning and also using the 2012 season robot design for training new members on Creo 2.


FIRST Team 1671 is on fire as usual!  In addition to team meetings every Thursday that bring in up to 50 students, the design team is meeting every Wednesday at a student's home for training.  We're up and running on Creo 2 and just about have all the new members up and running on Windchill 10.1.  The summer's project will be designing a new "swerve drive" from the ground up.  This will give the team a chance to do a new product development project without the normal stress of the actual build season.  A couple of objectives include a true Project Management Plan, quality detailed drawings, mechanism design and hopefully some structural analysis.  This is all in addition to the primary objective of designing and testing a new drive train.


I look forward to hearing what everybody else is doing out there!


Stay cool ,

Tag Templates in Arbortext

Posted by EmilMeindl Jul 11, 2012

I just discovered tag templates in Arbortext and strongly encourage any Arbortext user to start using them!


Where to find: Tools > Tag Templates


Use to create and insert frequently used sets of tags and content.  So far I have created tables where I only need to add cell information.


All my complaints concern large expressions and when worksheets are very expanded.

What bothered me in the course to develope my mechanical problem are

the following points:

The most important was the insufficient capability to mark large expressions at once.

Control +A works but was not ever wanted. Shift+click at the beginning and tracking  and shift and clicking and the end does not work

To mark expressions of 2-3 m in lenght can be marked only piecewise and copied piecewise.

A very boring work.

Mathcad dramatically slows down as soon as the worksheet enlarges and the expressions become bigger.

Deactivating great parts of the worksheet  will not accelerate Mathcad to work faster.

Derivating large expressions is very time consuming. Several times it did not work.

What has happened: Mathcad has not copied correcly.

For example. in an expression of 2 m in length I found  after several days instead of copying   sin(  )

I found  n( ) . The two charcters  si  of  sin( )  have been lost.  Derivating expressions of 2-3 m in length

could be done after  useing  the   "modifire"   simplify and lasted 20 minutes.

I assume internal storage areas are to small. One has to configurate these areas that multitasking is

possible, e.g. in the course of time Mathcad is controlling, and controlling and controlling I want to scroll

or copy or delete or scroll but it is not possible.

I work with Windows 7-64 and SSD 256 Giga, perhaps SSD  slows down after many writting cycles.

After deleting an expression scrolling is not possible for 2-3 minutes.

To copy large expressions is only piecewise possible.

Changing something in the middle of the worksheet lasts last 3-4 minutes. One has to wait, to wait,

to wait and so on.

I miss an error search algorithmus.  I have reached the limits of Mathcad :

At the end of my work I wanted to change some definitions at the beginning.  To enter about 40 characters

has lasted about 1 hour. Mathcad had nearly slowed down to zero.

This week I would like to draw your attention to Rob Leavitt the Director of Thought Leadership at PTC Global Services, the consulting arm of PTC. Rob is a long-time advisor to top technology and IT services firms and at PTC he works hand-in-hand with consultants, partners, and customers to advance understanding of key issues and challenges in product development, manufacturing, and after-market service.


Over the past couple of months Rob has been a regular on the PTC Product Lifecycle Stories Blog sharing the PLM insight he gathers through the course of the projects he works on and the people he works with.


Recently, I shared one of Rob´s pieces Slowing Down to Speed Up: 6 Steps to Effective PLM Planning but there are plenty of other pieces that are equally as valuable for companies looking to broaden their PLM knowledge in order to achieve greater business value for their organisation.
