Multibody - How to save out a single body to .stp, .stl?

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.

Multibody - How to get rid of a body

(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.

Recording of "I spy with my little eye (Remastered) Part 1 and 2"

During our B&W Webinar Week 2021, there are two sessions about " I spy with my little eye" which deal with the visibility of elements in Creo Parametric.    In the first part of this two-part webinar we analyze the different tools and methods that Creo Parametric offers to make items visible or invisible in the graphics area. The organizational layer ‚Body‘, that came out with Creo 7 also impacts the visibility of items. The webinar especially focuses on: Visibility basics of objects and items in Creo Levels of visibility Differences in assemblies, parts and drawings Functionality to drive visibility Layers and layer states Combined states Simplified representations Style states In the second part of this webinar we will discuss some practical examples of the visibility topic and show the related tools and methods. Finally we will show how SMARTUpdate can help to implement and handle the techniques to drive visibility. Have a look at the recordings now:  Part 1: (view in My Videos) Part 2: (view in My Videos)   We hope you like it!    Please feel free to ask questions here.

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.

01- Multibody – Intro, Model tree interaction and What’s that default body doing?

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!
