(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.

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

Hello everyone and welcome to blog post #20 in this multibody blog series.   Today’s blog is about illustrating a use case around geometry re-use that became enabled with the new appearance (and reference) propagations in Creo 10.0’s Body Boolean and Split Body features.  (see Multibody: Appearance and Reference Propagation for Boolean Operations (ptc.com) )  In essence we added two new options to Body Booleans as shown in the image below.   Those options allow you to control color propagation and reference propagation. That means for the below example, that when you subtract the orange and white bodies from the green eyelet part, we can propagate the color to the corresponding mating cut faces, and transfer references from the original to the new surfaces, so that for the attached annotations automatically move to the cut surfaces.       So, what is this good for? An example use case for this might be a scenario where you have standardized cut-outs for a connector where you model the cut-outs as fully detailed and annotated bodies in a library part.   These bodies will then be inserted along with their annotations into the connector part where we then subtract and pattern them. During the subtract operation we can then not only create the target cut-out geometry, but also have the colors and the annotation references be transferred to the cut-out surfaces. All the sematic references of these annotations would thus continue to show in a semantic query for selected annotations. Here you see a video illustrating the workflow for the above example in Creo 10.0     Thanks for reading.  I hope it was informative and this is a valuable use case for you. If you liked it, give it a Kudo.   Back to Creo Parametric - Multibody Home: Start Here!   Enjoy!....Martin

Blog Post 01 -    I wrote a blog post about the topic of Multibody – Intro, Model tree interaction and What’s that default body doing? I figured it made sense to provide a more thorough explanation that would attempt to answer all the questions likely to come up. Check it out and if you have any additional questions/comments, add them under the blog post itself. Thanks! Martin (view in My Videos)   Back to Creo 7.0 Multibody Home: Start Here!

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.

Multibody – Clearance & Creepage Analysis,   Hello all and welcome to another blog post in the multibody series.   In today’s topic I would like to make you aware of the multibody setup possibilities for clearance and creepage analysis. With the introduction of bodies in Creo Parametric 7.0, we also introduced support of the COMPARATIVE_TRACKING_INDEX parameter for bodies. If you add it to individual bodies of a part, you can define and control the conductivity definition separately for different bodies within a part. The attached video shows an example on a fuse part by defining conductive ends as body with a different CTI value. Once the body level parameter values are defined, you can see the conductive highlighting including the metallic ends of the fuse and excluding the red inner body.

A not-quite-right user interface can be a real nuisance day after day. But, an interface that’s just right for Sally might be all wrong for Tomas. Achieving true “one-size-fits-all” status is probably impossible. That’s why the Creo Parametric model tree is customizable. After all, your software is kind of like that Journey song … you know … “Any way you want it, that’s the way you need it. Any way you want it.”   Here are some tips for getting the model tree just how you want it.   Pick Your Columns and Column Widths.   Do you need to see more parameters in the model tree? Or, do you need to minimize columns and expand the graphics area, so you have more room to work? No problem. Here’s how to do it.   At the top of the model tree, click Settings and select Tree Columns. Add/remove displayed columns. Customize the width of the model tree, as well as the width of the other columns, using the dialog window (shown below) or by dragging the column separators in the model tree after you click Apply to add any new columns.   You’ll notice the model tree itself is defined as a column that can’t be removed from the list of displayed columns (see below). And you can set its width in the same way you set the width of individual columns. Additionally, you can quickly switch between showing and hiding the additional columns. Hiding columns can be useful when you want to shrink the size of left pane and maximize the graphics area.   Set Display Filters   Of course, some standard features, suppressed objects, and annotations appear in the model tree by default. However, did you know you can customize these model tree display filters for part and assembly modes? Here’s how:   At the top of the model tree, click Settings and select Tree Filters. Use the dialog window to select features to display in the model tree. Saving Your Model Tree Customizations   Model tree column settings, including column width, and model tree display filters are automatically stored, by mode, in the creo_parametric_customization.ui file. These settings load automatically when you open a new Creo Parametric session.   Model tree settings can be imported and exported in user customization file types (*.ui).   Want to see more? Watch the video below You don’t need to worry about messing up your current settings when you make changes to the model tree. You’ll notice several places where you can reset default settings when needed. You can even apply the reset to the current mode or all modes.

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.
