Community Profile: Mike Lockwood If you spent any time in the PTC community over the past couple decades, you’ve likely found good answers to your software questions from @MikeLockwood especially in the Windchill Community! According to our system, this user has posted 2241 times! “I’ve carefully read pretty much all postings in my areas of interest daily for all these years – and can reply to many with useful info,” he says.   That explains the 41 community achievement badges!   At the same time, he’s finding answers to his own questions. “I’m grateful that so many people are willing to voluntarily provide such good info. Within a day, I generally receive many good answers to whatever problems I’m facing.” But just to be sure, he admits that sometimes creates a tech support case in parallel with posting questions to the community.   Who's behind this prolific account?     Meet Mike Lockwood. Mike earned a BSME in college, and then began a career as a mechanical engineer for various medical device companies, including a startup. He focused on complex automated machines early on, and found that programming those machines awakened his interest in the computer/software side of his profession. As you might guess, it didn’t take long for his career to turn to CAD and PLM work. “I trained on Pro/E 15 in 1993 and have been using some version of it ever since,” says Mike. “I fell in love with parametric CAD, and by 1998, I accepted the CAD admin role at my company.” He’s been administering and supporting CAD and Windchill ever since, first for Alcon and, most recently, for Edwards Lifesciences. Plus he’s been a member of the Windchill technical committee for the past 15 years. When he’s not troubleshooting an Oracle database issue or explaining the nuances of parent/child relationships to new users, Mike enjoys getting outdoors. Skiing, snowboarding, surfing, and, lately, lots of long walks and exercise. Then there’s the music. Mike plays piano and can even blast out a saxophone solo (but just for fun, he says). Lockwood is retiring from his full-time job early next year but plans to remain available for contract projects (and hopefully for community members here). My Creo wish list After all these years, Mike knows Creo’s strengths, weaknesses, and workarounds—especially as it relates to Windchill. And since everybody has a wish list, we asked to see his. “Creo is superb and keeps getting better,” he assured us. “But there are a few things I’d like to see.” Modelcheck, when configured from the UI, resets all the tabs and it’s hard to read the text files. Modelcheck should make it easy to sort / filter for those configured as Error / Warning / other. The naming of the various Creo apps that are not Creo Parametric (e.g., Creo View, Creo Illustrate) is confusing to users, especially when these are used with SolidWorks data. Family tables continue to be great for CAD but challenging for CAD in PLM (Windchill).  Would like to see more info and recommendation on alternatives (like maybe inheritance). Autonumbering with Windchill is the default and works for some.  It is of great value to have drawings and the model(s) on them share a root CAD Doc Number / filename.   On behalf of the whole community, thanks Mike for your efforts, insights, and help over the years. We wish you a long, healthy, and invigorating retirement and look forward to your next 2000 posts here on the community!

Hello all and welcome to another blog post in the multibody series.   Today’s topic represents an add-on to the previous post : How to “position” a body. The workflow example  in the below video explains in more detail how you can leverage these (previously discussed) positioning operations  to create a design like this very easily.   he intent here is to drive the cutout of the blue body parametrically based on the defined range of angular movement of the yellow pin. The workflow example makes use of the Flexible Modeling Move feature to create something like a “simplified motion envelope” driving the cutout opening in the blue body.      (view in My Videos) Thanks for reading.  I hope it was informative.

Hello all and welcome to another blog post in this multibody blog series. Todays topic: How to “position” a body.   You might wonder why I put the word position into quotes. The reason for this is that when we talk about positioning, many of us start thinking of positioning component-like objects.  The fact that components have their system of reference (e.g. coordinate system including the origin) makes it natural to understand that positioning transforms that coordinate system from one location and orientation into another. Geometric bodies do represent a volume of geometry referring to the part’s reference system, therefore the positioning of geometric bodies should probably be better called “Moving” geometry. Anyway, after this introductory thought, I hope you enjoy the video illustrating how this is done in Creo. (and you won’t be surprised: we are going to use the “Move”-Feature for this workflow 😊)   (view in My Videos)       Thanks for reading.  I hope it was informative.

Hello all and welcome to another blog post in this multibody blog series. Todays topic: Construction bodies! Construction body are a pretty unique, powerful concept in Creo’s multibody implementation. As such it is really important to know about them and to understand how to use them. So, what are construction bodies? Construction bodies are bodies that are used for the design of your model, but do not contribute to the final geometry or mass. That means that similar on how you used quilts in the past to create additional geometry helping with the construction of your design, you can now do the very same with solid geometry. The construction attribute of these bodies will then help you to differentiate that geometry and automatically exclude it. Excluding them from mass properties is just one out of more than a dozen workflows where they are treated special. You will find more details in the video.   (view in My Videos) Thanks for reading.  I hope it was informative.

Some Creo modules or applications such as NC or mold design modules do not yet fully support multibody models (as of Creo 7.0/8.0).   Watch the below video to understand what you can do in these cases and how you can get to the required reference models for these downstream applications.   Thanks for reading and many thanks to my colleague Beat Fretz who provided this example model (view in My Videos) to me.  I hope it was informative.

Hello everyone and welcome to another blog post in this multibody blog series. This is a mini-post based on a question that I received: “If I have a designed a multibody model, how can I save out a single body to STEP , .STL or any other format?” The answer is pretty straightforward and involves either the remove-body feature (see blog post #10) or construction bodies (see blog post #13) or derived models (see blog post #12 and later).   Method #1: Remove all other bodies using the remove-body feature Export(“Save A Copy”) the model to your desired format Undo the remove / delete the remove-body feature / suppress the remove-body feature Method #2: Set all other bodies to “Construction body” Invoke Export(“Save A Copy”) the model to your desired format Open the “Options”-menu in the “Save A Copy” dialog and ensure the Construction Body checkbox is unchecked Finishing the operation will then only save the remaining (non-construction) body The problem here might be that you need to remember which bodies to unset as construction afterwards if applicable Method #3: Create a derived model that only contains the body to be saved The easiest way to do this would be to select the body and then invoke “Create part from body” from the right mouse button menu. This creates a new part only containing the selected body allowing you to export it on its own Or Create new part and bring the desired body into the new part manually by using  the “External Copy Geometry” feature (view in My Videos) Thanks for reading.  I hope it was informative.

(Remove a body versus hide a body vs delete body vs deleting/suppressing contributing features) Hello everyone and welcome to another blog post  in this Creo multibody blog series. Today’s topic: Various way to “get rid of” a body and their differences Let’s have a look at various concepts that you might want to apply depending on what you want to achieve. Creo offers the following: Hide/Show a body As with other objects you can use show/hide commands to control the visibility of bodies. This is just changing the visual appearance toggling the display for a selected body and does neither remove the body object from the model, nor its geometry or mass “Consume a body” in Boolean features Boolean features have a Keep body option, to control whether the tool bodies should be consumed in the operation or whether a copy of their geometry should be used for the Boolean operation. Consumed bodies are shown in the body folder depending on the tree filter settings.   “Remove body” feature This allows you to create a feature to consume a body. The body cannot be used further, and its geometry is removed. Note that the features are not removed or deleted but the geometry created by those features will not show anymore. Remove body is a feature so you can suppress or delete it or roll-back the model to before the Remove-Body feature to get the body back.   Would suppressing contributing features also work to get rid of a body? This could potentially work in very simple examples for cases where these contributing features have no dependent children features and none of the contributing features contribute to or impact other bodies as well. In contrast to that, the remove-body feature leaves the other design features intact and just removes the body at time of its regeneration. Note that the body is still active and used in regeneration states before the remove-body feature.   Good examples that illustrate the benefits and need for a remove body features (where suppressing features wouldn’t help or not be possible are:   a situation where you bring several bodies A,B and C into a part via a single import feature or copy-geometry, or merge/inheritance feature and you want to only remove body B. a situation where you mirror a part design having bodies A,B and C to get A’, B’ and C’ and you just want to get rid of B’     Delete a body The delete body command completely deletes the body from the model for situations where you want to entirely get rid of the body object, free up its name in the name space and entirely remove it from the internal model entity data base. This is possible for two workflows: Delete new empty body Delete a body that doesn’t have any contributing features anymore   (view in My Videos) Thanks for reading.  I hope it was informative.

As part of our B&W Webinar Week 2021, there is a session about "Take your automation to the next level with Virtual Master Model" with our partner SIGMAXIM.    Keeping rules and logic in Creo has its benefits. But, it also has its drawbacks. Most of us have tried Family Tables Pro/Programs Relations Over loaded assemblies   The Virtual Master Model (VMM) concept gives users the advantage of retaining the information and rules saved in the master model concept without the disadvantage of lugging it around in Creo and Windchill environments. How did VMM make it better? By creating a rules engine and linking it outside Creo. Imagine being able to quickly change and update models without having to dig through code or other logic. Everything users do is based on rules and logic which cascades into other decisions and results. VMM offers the flexibility to keep the resulting Creo data a concise model set without the burden of unnecessary data. ETO can now be included in your automation road map. VMM is smart enough to handle complex and unique rule sets. You could also call it low coding.   When: Oct 12th at 3 pm (CEST)    Here is the recording for you: (view in My Videos) Please feel free to ask your questions.
