Hello, CAD!

2 Posts tagged with the xma tag

Happy New Year, everyone! I hope you all had a good start into 2013. After all the holidays and time off work, I have finally gotten back to my usual routine. One of my resolutions for this year is to pick up my blogging again after a somewhat slow 2012…

So far, 2013 is making it easy for me, as here in PTC University, we have many new things coming up that are worth discussing in more detail.


Today, I would like to start with Expert Model Analysis. Wait, that is not new, is it? Yes and No!


I have, in fact, blogged about Expert Model Analysis before in 2011 – so it is not new, per se. To date, however, Expert Model Analysis (XMA) has been a consulting tool to help us engage our customers in a meaningful way about potential areas for value realization. Put another way, we analyzed the customers’ data to see if they are really getting the most possible value out of the technology.…

Now, we are going to offer this as a product! In many engagements, customers have consistently wanted to own this tool in-house so they could regularly perform scans on their own. This demand for XMA initiated the development of XMA Desktop which will soon be released as a new PTC University product (likely in the Spring of 2013, but we haven’t pinned down a date yet).

PTC University's Expert Model Analysis (XMA) deepens your understanding of PTC Creo Parametric and Pro/ENGINEER models. It evaluates your models and provides guidance to improve your modeling practices.

XMA scans and analyzes large quantities of PTC Creo Parametric and Pro/ENGINEER models. Each report of an XMA scan includes over 50 areas of analysis around Geometry Quality, Design Intent Strength, and Model Complexity. 

Curious? Well, you don’t need to wait until release of the new XMA Desktop product. You can try it NOW.

You can download a free, 30-day trial of PTC University Expert Model Analysis here and get a sample of the full features and reports available in XMA Desktop . Expert Model Analysis works with PTC Creo Parametric and all models last saved in Pro/ENGINEER v15 or higher (including PTC Creo Elements/Pro).

… and don’t forget to let us know your feedback. Feel free to comment below – thanks!


Earlier this year, PTC University came up with a new service for our Creo Parametric (and Creo Elements/Pro and Pro/ENGINEER) customers: Expert Model Analysis, or for short: XMA. Basically, we have developed a tool that allows our consultants to run an in-depth analysis on the customer’s model data to spot opportunities for skills or best practice improvement.


Using over 50 measures and objectives, XMA helps uncover potential issues in the 3D designs. This is a great opportunity for the customers as it allows them to detect sub-optimal areas and take corrective action. If you’d like to learn more about the actual offering, take a look at:



Results of an XMA scanThis sounds like a great tool, and I reached out to our consultants to learn about the things beyond the official collateral. Turns out, I was advised to talk to Steve Meyers, whom I had already interviewed about his Creo tutorials on LearningExchange. Lucky me, as Steve is great to work with and I immediately got a time set up for a quick call with him. So here we go!


Bettina: The analysis itself is referred to as “scan” – how many scans have you done for our customers already?


Steve: I have personally done 6 so far and the average number of models we scan for this analysis is ~350.


Bettina: Great, this sounds like you are in good shape to give feedback. So, what are your findings so far – Is there anything that the customers have in common?


Steve: So far, I was able to discover two common issues:


  • In the Geometry Quality category, all of the scans I have done show a need to pay attention to the accuracy setting in models.  The advice given by XMA is to use Absolute Accuracy when appropriate, and to tune part accuracy for small geometry (typically large parts that have some small features).

  • In the Design Intent Strength category:
    • Most customers can improve their models by avoiding edge references, and by improving feature order (place rounds and chamfers on the model later).
    • For customers who tend to create complex geometry, I often see a warning about Complex Sketches (sketched that have more than 25 entities in them).
    • Most customers could improve their models by fixing “Design Intent Unclear” warnings that appear during modeling.


Bettina: Steve, it sounds like XMA can identify a huge optimization potential – especially with very large organizations. When I imagine just one best practice that can be implemented as a result of an automated analysis, but is then multiplied by a number of x sites and/or design teams in an organization… awesome.


Steve: Yes, XMA does a great job of showing customers where it makes sense to spend time on improving their modeling.  Efficiency is key for all organizations. The subject of CAD modeling standards always comes up.  Some companies have no published standards for modeling practice, and others have standards that are published, but are either outdated, or not enforced.


Bettina: Thanks for taking the time to talk to me, Steve! I am sure, I will get back to you in a little bit to see if we can actually talk to one of your customers, soon, so we get to know another perspective!
