Creo Parametric Tips

May 23, 2020

In this series, our expert product managers are going through how-to Creo tips. Each bite-sized tutorial is less than 5 minutes long. It's a perfect opportunity to learn something new or get a refresher on a workflow you haven't used for a while. Below you'll find about 15 minutes of video tips aimed at helping you improve your Creo proficiency. Ready to get started? Geometry Backups on the Fly When you create external references among features in a design, local references to features in a part, or placement references in an assembly, reference creation and backup tools are provided for specifying system behavior. In this tutorial, Arnaud van de Veerdonk, Creo Product Manager, shows you how to use Update Control functionality through, on-the-fly created, Geometry Backups. Watch the tutorial: Flexible Management of Item Visibility in MBD When working in model-based definition (MBD), three schemes are available to manage the visibility of any combination state in a model: MBD state: Used to manage the visibility of both annotations and supplemental geometry by direct assignment to a combination state. Semi-MBD state: Used to manage the visibility of annotations only by direct assignment to a combination state and to manage the visibility of supplemental geometry by using layers. Non-MBD state: Used to manage the visibility of both annotations and supplemental geometry by using layers and layer states. In this tutorial, our Creo Product Manager shows you how the 3 schemes can be used to manage visibility of annotations and supplemental geometry, such as planes, axes, coordinate systems, points, and curves. Watch it in action: Spiral Geometry in a Snap Using section relations in combination with the TRAJPAR parameter, you can create a section whose size and shape vary along a sweep. TRAJPAR, which ranges from 0 to 1 as the section sweeps along the trajectory, is the trajectory parameter used in relation for variable section sweeps. In this tutorial, Paul Sagar, VP of Product Management, shows you how to build specific types of spiral geometry using the TRAJPAR parameter and a variable section sweep.

Here's your next set of how-to tips in the series of quick Creo tutorials presented by our expert product managers. Each bite-sized tutorial is just a few minutes long. It's a perfect opportunity to learn something new. Take a look below at about 15 minutes of video tips to help you boost your Creo proficiency. Let's get started. Give Your Manikin a Backpack, a Hat, or a Beer A manikin model is considered a standard Creo Parametric assembly. You can add ancillaries (sub-assemblies) to the manikin, like a backpack, tool, hat, etc. These help you test your design for ergonomic compatibility and other human-centric requirements. Further, if the library doesn't contain what you need, you can design a custom item to be used with manikins. In this tutorial, Arnaud van de Veerdonk, Creo Product Manager, shows you how to add ancillary objects to manikin models. See Subtractive Manufacturing Toolpaths in the Model Tree Your workflow for accessing subtractive manufacturing toolpaths and references might be more complicated than it needs to be. How many clicks does it take for you to see them? In this tutorial, Creo Product Manager, Jose Coronado shows you how to enable a mode in Creo NC to display the toolpath and its references just by clicking on the toolpath name on the Model Tree. Find That SolidWorks Command in Creo Parametric For users who are new to PTC Creo Parametric, but have previous experience with SolidWorks, the Creo Parametric Command Search Tool allows you to map SolidWorks commands to Creo commands. In this tutorial, Director of Product Management, Martin Neumueller demonstrates: For more tips from our experts, watch the Tips from the Creo Masters main page.

Here's the next set of quick Creo tutorials presented by our expert product managers. Each tutorial in this series is just a few minutes long. These tips are aimed at helping you learn a new skill. Or, for experienced users, helping you learn a new workflow to perform a skill you've been doing for years. Below you’ll find about 15 minutes of video how-tos to help you improve your Creo proficiency. Let's get started. Combining Simplified Reps and Augmented Reality for Lightweight Experiences Simplified Representations allow you to control the amount of data retrieved for a component. These can be helpful for to publishing lightweight AR experience. In this tutorial, Creo Product Manager, Luke Westbrook, shows you how to use simplified reps with your next AR experience. Here's how: Using Sketch Region You can create geometry containing extrude, revolve, fill, and sketch features quickly using sketch regions. Using Sketch Region reduces the need to perform project and trim operations within Sketcher. It also offers a flexible way to use portions of a single sketch as the basis for several sketch-based features. In this short tutorial, Director of Product Management, Martin Neumueller, shows you how to use Sketch Region selection to quickly create geometry with supported sketch-based features. Watch the tutorial: Dimensioning: Custom Fractions You can display dimensions in Creo as either decimals or fractions by setting a configuration option. Then, you can set up custom fraction denominators and use them to define your model's dimensions. In this tutorial, Creo Product Manager, Michael Fridman, shows you how to dimension with fractions instead of decimal representations, and then add a custom fraction denominator, when needed. See how to do it: For more tips from our experts, watch the Tips from the Creo Masters main page.

We're offering a series of quick Creo tutorials presented by our expert product managers. Each of these tutorials are just a few minutes long. These bite-sized tips are a perfect opportunity to learn a new skill or ensure you're following best practices. Below you’ll find about 15 minutes of video how-tos to help you boost your CAD know-how. Let's get started. Shrinkwrap All Quilts When you create a Shrinkwrap feature, by default, Creo automatically analyzes all components in the assembly and determines which ones will be included in the shrinkwrap. This could result in subassembly quilts being excluded. However, you can use the Search Tool to help find and select all quilts in the assembly. In this tutorial, Arnaud van de Veerdonk, Creo Product Manager, shows you how to use shrinkwrap to copy all quilts from all models in an assembly. Watch the tutorial now: Work with Custom Manikin Postures You can test designs for ergonomic compatibility and other human-centric requirements using a Creo Manikin. If you can't find a manikin that fits your design scenario, you can create a custom posture for your manikin. Then, you can save the posture, use it for an analysis or apply it to any other manikin later. In this tutorial, Arnaud van de Veerdonk explains how to create, store, and apply custom manikin postures. Here's how to do it: CNC Drilling on Imported Geometry Simplify your work creating hole-making sequences over imported geometry with tips from Creo Product Manager, Jose Coronado. In this tutorial you'll see how to easily create CNC drilling sequences by: Creating drill holes on imported geometry (no axes needed). Using the Auto Depth option so you don't need to manually select the end of each set of holes. Watch the tutorial: For more tips from our experts, watch the Tips from the Creo Masters main page.

As promised, here is Post 1 in the new series of Creo tips from our expert product managers. Each post includes about 15 minutes of video how-tos aimed at skilling up your CAD proficiency—whether you’ve just started using Creo or consider yourself an old pro. So much for the ado. Let’s jump in! 1. Getting Granular: Copy Geometry from Multiple Components You can pass any type of geometric reference information and user-defined parameters to and from parts, skeleton models, and assemblies using the Copy Geometry feature. Normally, you can only copy geometry (like curves, surfaces, or datum planes) from a single source component. However, in this tutorial, Creo Product Manager, Arnaud van de Veerdonk shows you how to manually copy geometry from multiple assembly components using a single shrink wrap feature. Watch how to do it: 2. Simplify Your Mesh by Removing Small Features … Quickly and Easily Simplifying a model by removing small geometric features, holes, and areas that increase the complexity of the mesh can speed up analysis and simulation processes. But you might find it time-consuming to remove these features manually. In the tutorial below, Martin Neumueller, Director of Product Management, shows how to quickly defeature a model in preparation for simulation with flexible modeling and geometry search capabilities provided in Creo Simulate and Creo Parametric. 3. Manipulate Rounds Like a Boss: 3 Tricks You've maybe noticed that Creo creates default, context-sensitive transitions when you add rounds to a model. These are just the default and, like most other elements, they can be changed to fit your needs. In this short tutorial Paul Sagar, VP of Product Management, shows you 3 tricks for creating advanced round geometry inside Creo. You'll learn how to: Add a round to 3 intersecting edges. Understand the power of round pieces Apply different round values to a tangent chain of edges. Extend a round along a tangent chain of edges, controlling the end transition geometry. Watch this short tutorial to learn how: For more tips from our experts, watch the Tips from the Creo Masters main page.

In some cases, you may not want Import Validation notifications when opening components in Creo Unite. For example, a model may have known issues, but you still want it in Creo for reference or for placements indicators. Many users asked us for a way to toggle those notifications off (and on) after a model had been opened or imported. With Creo 6 or later, now you can. With import validation notifications disabled, you don’t receive a report of failed validation in the Notification Center, or an indication of failed validation in the Model Tree. Here’s what you need to know to set your default to enable/disable these notifications: To Enable or Disable Validation for Individual Components If you want to disable or enable import validation notifications for individual components, right-click the component in the Model Tree and select Import Validation. Image: Enabling import validation notifications for a component from the Model Tree Note that when you select Enable Import Validation, it does not include import validation for models that have been imported or opened. And, it does not change the status for imported or opened models when they are modified. To Enable or Disable This Validation by Default If you want to enable/disable import validation notifications for all components, select or clear the Enable Import Validation checkbox in the Creo Parametric Options dialog box.

Working with model-based definition (MBD)? Here are a few features that simplify the handling of child annotations, based on the status of their parent annotations. You can find them in Creo 6.0 and later. Take a look: To Exclude Annotations Based on Parent Status When a parent feature is no longer available, you can exclude child annotations from your design and graphics based on the parent feature’s status and detail option. Suppression of parent feature using the mini toolbar as a trigger to exclude child annotations. Child annotations may be excluded when: The parent feature is being excluded by simplified representation or family table instance. The parent feature is being suppressed. The parent feature is being deleted. The parent section was deactivated, and its section hatching is also hidden. You can further configure what child annotations you want to exclude from the model. To do this, go to File > Prepare > Model Properties > Detail Options to change child annotations that are excluded using these 4 options: Exclude annotations of deleted: Determines whether to exclude annotations that are children of deleted features. Exclude annotations of excluded: Determines whether to exclude annotations that are children of excluded features. Exclude annotations of section: Determines whether to exclude standalone annotations that are children of section features when the section is not active and not shown Exclude annotations of suppressed: Determines whether to exclude annotations that are children of suppressed features. Image: Situations under which annotations may be excluded For example, to exclude a child annotation in cases where its parent feature is being suppressed, first make sure that the corresponding detail option for this case is set. Then you can highlight the desired feature, right-click, and select the option to suppress the highlighted feature from the mini toolbar. This will exclude the child annotations of the suppressed feature and a special glyph will appear for them in the model/detail trees. To View Annotation Status in the Model Tree You can easily check the status of your annotations in the Model Tree. Image: MBD annotation statuses display in the Model Tree The following statuses are available: Excluded: Missing References: Modernized annotations that are failing with weak references. Failed: Modernized annotations that are failing with strong references. Unconverted: Legacy nonconverted annotations. Not Available: Non-modernized annotations that cannot be converted into modern annotations. Search Tool: Look for Annotations Based on Their Statuses Finally, you can use the Search tool to find annotations based on their statuses (Excluded, Missing References, Failed, Not Available). Here’s how it looks: Image: Search for annotations based on their statuses. Watch the Demo See a demonstration of these tips in the video below.

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.

Do you create or modify features in Creo? Now you can speed up your work by taking advantage of feature mini toolbars and dimension toolbars, available in Creo 6.0 and later. You'll find these toolbars for features frequently used with part and sheet metal design. Here's everything you need to know to use them. To Open Feature Mini Toolbar in Creo To reach a feature mini toolbar, simply click in the graphics area of your Creo screen. A mini toolbar appears providing you with quick access to relevant options for your feature. Right-click in the graphics area to open the mini toolbar AND a shortcut menu. Image: Feature mini toolbar and shortcut menu Note that in addition to the feature mini toolbar, there are also dimension toolbars that allow you to access some commands/options that were previously available only via the shortcut menu for the dimension. Bonus: Tabs That Reveal More If you’re in a newer version of Creo, you’ll see that tabs have a new look. In Creo 6 and later, when you open a tab, a short description (plus a link to a Help page) appears directly in the UI. Image: When the Hole tab is active, a short description appears in ribbon area. Watch the Demo You can see these tips and more demonstrated in the video below. Why Wait to Upgrade? Each release of Creo includes dozens of convenient features like these that make your work faster and more intuitive than ever. Learn more about what's in the latest versions of Creo today!

You probably know that Creo 6.0 became available recently. You can see an overview of what’s in the release here. Among the new capabilities, we’ve added homogenization for those simulating lattice structures. Arun Chavan from our development team offers this closer look at how homogenization works, why it matters, and the data behind the solution. What Is Homogenization? Homogenization is a process of extracting effective material properties from a heterogeneous material and then viewing it as a continuum on the macroscopic level with the extracted properties ascribed to it. Homogenization has many important and practical applications in material sciences, particularly where repeating lattice structures (and composites) are used. That’s because computations of models with many lattices often prove difficult, time-consuming, and error prone. With homogenization, you have an effective approach for describing the overall behaviour of large lattice structures, without the complexity. Improving Performance in Creo Say the number of cells in a structure exceeds 24,000. You may find it impractical to store or simulate full or simplified geometry models of that size in your system. These tasks simply require a too many computational resources. To facilitate the modelling of large lattice structures, Creo can now represent them as a continuous solid with material properties equivalent to those of the lattice structure.A solid with these effective material properties will have the same mass properties, stiffness, porosity, etc. as the original lattice structure. Image: Creo 6.0.0.0 uses homogenization methods to facilitate the modelling of large lattice structures by computing and providing Creo Simulate the equivalent homogenized material properties. 1. Lattice structure; 2. Homogenous Continuum; 3. Process of Homogenization What’s the Homogenization Procedure? Here’s more details about how it works: For a given lattice topology, we identify a unit cell. We apply Periodic Boundary Conditions on the unit cells and calculate overall effective material property. We then use these homogenized material properties for simulation. Lattice Structures Then and Now In earlier Creo releases, to analyze lattice structures, the software would either create a full geometry lattice or simplified lattice. These both led to computationally intensive procedures, especially when the lattice region was large or included densely packed cells. In Creo Parametric 6.0.0.0, the “homogenized” representation defines dense lattice structures without creating them in the model. An equivalent material property of the lattice region is extracted and used to get the equivalent mathematical model of material. In Creo Simulate, these equivalent homogenized material properties are then used to simulate the structure for linear static and modal response of a part. As a result, it takes less time to define a lattice, the model size is reduced, and simulation moves quicker. The Data: How Do the Results Compare? We compared Creo 6.0.0.0 results for three lattice structures and all of them compared very well with baseline. The homogenization results converge when compared with full lattice geometry models. As you can see in the table below, the error declines with an increase in the number of lattices in a given volume.
