Lattice Structures in Creo: What You Should Know About Analysis and Licensing

  With the wide-spread use of additive manufacturing, you now have more options than ever before for part and assembly design. That’s because without the restrictions of traditional manufacturing, more intricate structures can now be used to optimize weight, strength, and even heat distribution.   (For an overall introduction, read our Beginner’s Guide to Lattice Structures in Additive Manufacturing.)   In a recent presentation from PTC University, Matt Huybrecht discussed and demonstrated new features in Creo that support lattice structures for those who want to use them. However, before you start, a few questions came up that we thought you might find interesting:   Can I do a structural analysis on stochastic lattices? YES! The DISPLAY of the geometry is that of simplified representation geometry, but the lattice geometry does contribute to mass properties calculations. Therefore, you can leverage it in structural analyses.   How is the additive manufacturing functionality licensed in Creo Parametric and what are the differences? There are two licenses available:       Creo Additive Manufacturing Extension (AMX) – An add-on extension that provides lattice structure creation and optimization and printer tray setup. It includes basic additive manufacturing capabilities, including: Out-of-the-box 3D printer support for Stratasys and 3D Systems printers. Model preparation (tessellation) Printer tray setup Global scaling Printability validation Model interrogation Calculations of build material Option to order 3D print       Creo Additive Manufacturing Plus Extension – An add-on extension that provides 3D metal printer connectivity, printer management, and tools to automate support structure generation.    For even more guidance from the PTC University team, check out the new LEARN classes now available online.

07 - Multibody – How to display, use or call-out a body parameter – Part 1

Hello everyone and welcome to blog post #7 in this multibody blog series. This post also attempts to answer another body parameter related question: How can I display, use or call-out a body parameter? If you want to call out a body parameter then you have to use the syntax as explained in the Creo help here.   &<param_name>:BID_<body_feature_ID> Or &<param_name>:BID_<body_userdefined_name>   Note: For bodies that have the default name (body 1, body 2, etc) you cannot use the system-defined default body name but you have to use the body’s Feature ID. (The reason is that the system-defined names such as body 1, body 2, etc are localized and translated into other languages and therefore not representing stable references across languages.)   Example: Let’s assume we have 2 bodies. Here their names and parameters list.     To call out the parameter “MY_BODY_INFO” for both bodies, we can now use the following for body 1 &MY_BODY_INFO:BID_-5778   And one of the following options for the WHEEL body (which has id 6105) &MY_BODY_INFO:BID_6105 &MY_BODY_INFO:BID_WHEEL   So if you create a note and enter: You will see the resulting note text being: I think we have a preference of using body names. Therefore the system automatically tries to convert the body IDs to body names where possible. So when you go back to the call-out symbol definition, you will see it being changed to   Thanks for reading. I hope it was informative.   Back to Creo 7.0 Multibody Home: Start Here!   Enjoy!....Martin

06 - Multibody –How to display a body parameter in the model tree

Hello everyone and welcome to blog post #6 in this multibody blog series.   I got asked recently : How can I display a user-defined body parameter in the model tree? If you are interested in that as well, here is how you do it. Let’s walk through an example step-by-step.   Step 1) Let’s assign a body parameter (and let’s call it for example “MY_BODY_PARAM”)   Step 2) Open the Model Tree Columns display dialog   Step 3) Select the Type: Body Params     Step 4) You might notice that the list shows system parameters related to bodies (e.g. PTC_ASSIGNED_MATERIAL), but not the newly added user-defined parameter  Step 5) Manually enter the user-defined-parameter (in our example “MY_BODY_PARAM”) into the Name field     and click the double-arrow to move it into the displayed columns     Step 6) Click “OK” and ensure model tree columns are displayed. Now you should be able to see your body parameters as part of the displayed model tree columns   q.e.d. 🙂  I hope that helped.   Back to Creo 7.0 Multibody Home: Start Here!   Enjoy!....Martin

04 - Multibody – Creo 7.0.1 enhancements

Hello Multibody community!   Welcome to this new post on the multibody capabilities that we introduced with Creo 7.0. Meanwhile, the first maintenance release Creo 7.0.1 had been released and it does contain several refinements/enhancements to the initial set of capabilities. Here a list of those enhancements: Boolean Operations In Creo 7.0, the “Keep bodies” option in Boolean Merge, Subtract and Intersect features was only available during feature creation. Now it is also enabled during feature Edit-Definition workflows Curve feature  You can now select a body (in addition to the previously available object types Quilt and Surface) when checking the “Place curve on surface” option. Data Exchange The “Import multiple bodies into one part” option is now available in File/Open (Unite) and ATB-enabled Import workflows Improved Body Handling Improved body handling when a feature-owned body (e.g. a body created by split-body, import or data sharing features) gets deleted from the model Data Sharing and Reference Pattern robustness enhancements for specific multibody situations Aligned Material reporting The mass properties report uses the parameter PTC_REPORTED_MATERIAL in all places where material is reported. New configuration option for multi-material parts:   ptc_reported_material_mp_report Windchill support for designated bodies If you are interested in seeing demos of the above capabilities 1)-6), take 15mins to watch me walking through them. Beyond the new capabilities you might also find some of the multibody concept related background information useful. (view in My Videos) Note that I plan a dedicated video showing the Multibody related Windchill interaction for my next post.   Back to Creo 7.0 Multibody Home: Start Here!   Enjoy!....Martin

03 - Multibody – Many ways to trim a body

Hello Multibody community!   As I recently have received some questions and suggestions around how to trim a body, let me spend a few minutes today to tackle that topic.   #1) How can I trim a body by a datum, surface, quilt etc? I have heard this question several times, as there is no “Trim Body” tool currently in Creo Parametric 7.0. Still, we do have other tools that you can use to trim body geometry.  If you want to trim a body by a datum, surface, quilt, this is the “Solidify-Tool” with the “Remove Geometry” option. Here are two examples how that would look like. Two hints if you want to try it: Set the body that you want to trim as default body. This saves you from needing to access the body options panel in the feature  Pick the trimming object first to get access to the solidify feature         #2) How can I trim a body by another body? This is often useful to perform Boolean operations with a trimmed “modifying body”. Here is an example of that where you might want to trim a “library-type”/”standard-type” grey tool body to only merge its upper half to the yellow plastic part. The most robust flavor of this might involve body split and body remove, but there are actually several more workflow flavors on how to achieve the above with mostly 3 steps. If you are interested in seeing all of different ways to achieve the result, watch a quick 6mins movie of that here:   (view in My Videos)   Back to Creo 7.0 Multibody Home: Start Here!   Enjoy!....Martin
