Did You Know? PTC Creo 3.0 Enhancements: Standard Hardware and Fasteners

With the release of PTC Creo 3.0, PTC Creo Parametric users now have access to an expanded library of standard parts and fasteners as well as an intuitive user interface to speed up the process of adding hardware to your assembly design. Jim Barrett Smith, Product Manager at PTC, gives an overview of the new capabilities:   To define the position of a fastener, select the datum point, axis, or a hole. You can select two aligning surfaces to define a fastener connection with a thread. Or, you can select two opposing surfaces to define a fastener and nut connection.   Next, select a fastener from the comprehensive library of fasteners. Choose the size of the thread or measure the thread size using an existing hole.     Selecting a fastener from the standard parts library   You have the option to set the length of the fastener yourself, or to have it set automatically. You can also control the hole tolerance and choose whether to have a counterbore on the top, the bottom, or both.   Setting the length of the fastener     There is a 2D preview in the dialog which updates with as you define the fastener details. Furthermore, you can click Preview to see a 3D view of the fastener in the graphics area.   You can get a 3D view of the fastener by selecting Preview     When you are satisfied, click OK to assemble the fastener.   After a fastener is assembled, you have the ability to reassemble or redefine it. Furthermore, if you reassemble an existing fastener onto a pattern, you will have the option to pattern the fastener. This saves significant time and effort.  If needed, you can choose to delete all patterned fasteners by simply selecting one and clicking Delete.     Check out our video tutorial on the PTC University Learning Exchange (“PTC Creo Intelligent Fastener (Lite)”) to learn more. Stay tuned to our “Did You Know” blog series as we cover all of the exciting, new enhancements in PTC Creo 3.0.     For more in-depth product feature explanations, visit our Tech Tips area.   Have some ideas about what PTC Creo product features you’d like to learn more about? Send me a message or leave a comment below and we’ll write up the best ideas from the community. Thanks for reading, looking forward to all of your feedback!   In case you missed it, check out our recent Did You Know posts covering PTC Creo 3.0 enhancements: Flexible Pattern Tool in the PTC Creo Flexible Modeling Extension Aligning Freestyle Geometry

Did You Know? Creating Helical Sweeps for Springs

This week’s Did You Know, provided by our Director of Product Management Paul Sagar, teaches users how to create helical sweeps for springs using the sweep tool in PTC Creo Parametric. With this tool and its dashboard interface, creating springs is quick and easy. Paul shows us how to do so in three easy steps:   Step 1: Start Sketching the Spring’s Profile The helical sweep tool is located in the Shapes group of the modeling tab, under the Sweep Type drop down.   The sweep type drop down menu     After the helical sweep dashboard opens, go into the References tab and click Define to begin sketching the profile of the spring.   In this example, we’re going to sketch the spring’s profile on the FRONT datum plane in a 2D orientation.   Step 2: Define Spring Properties First, define the spring center line. This will be the center axis of the spring (the axis of revolution).     Defining the axis of revolution on the center line   Next, add a vertical line to the left of the center line to represent the profile of the spring. This will be the diameter of the spring defined through the center of the spring’s wire. Complete the profile sketch.   Now define the Helix section by choosing Create or Edit Sweep Section in the dashboard.   The diameter of the wire will be sketched at the start point of the profile, using a circle. But you can use any shape you need.   Step 3: Add Relations   The helical sweep dashboard makes it easy to edit the pitch value of the spring, or toggle the spring from a right hand to left hand turn. The finished helical sweep will be seen dynamically on the screen. Complete the feature.   To finish the spring however, we want to make sure the spring maintains six coils no matter how much it’s expanded or compressed. To do this, we’ll need to add a relation to the part.     Adding relations to ensure this spring has six coils     This relation will be used to control the spring’s pitch as it expands and contracts. Go to the Tools tab and open the Relations Dialog box. We can see that the height of the spring is D1, the pitch is D2, and the diameter is D0. We need to write a relation that says the pitch equals the height of the profile divided by 6. This will ensure that the spring always has 6 coils. Now we can test it by editing the height dimension to compress and expand the spring. The final product: We can continue to compress and expand the spring without changing the number of coils     Check out our video tutorial on the PTC University Learning Exchange (“Creating Helical Sweeps for Springs”) to see this advice in action. We’d also love to hear your suggestions for working with helical sweeps below.   For more in-depth product feature explanations, visit our Tech Tips area.   Have some ideas about what PTC Creo product features you’d like to learn more about?

Did You Know? Tips for Fewer Model Failures with Intent References

The first edition of our new “Did You Know” series featured advice for creating advanced round geometry in PTC Creo Parametric. This week Don Breda, Product Manager at PTC, shows us how to use intent references in PTC Creo Parametric to avoid model failures.   Here is the situation we are trying to avoid: let’s say you are trying to change a square interface into a hexagonal interface. You redefine the extrusion and delete the square. Now, the system says you are deleting entities that are referenced by other features. Hence, we’re left with feature failures. In this particular instance both a draft and round have failed when we changed the section that is used to define the extrusion.   What causes this failure? Both the draft and round were referenced to the individual surfaces and edges of the extrusion.   How do I avoid this problem? Change the way these features are created by using intent references.   Edit the Definition of the Draft feature, and remove the individual surface references. Next, “query select” by clicking the right mouse button until all the sides of the extrusion are pre-selected - the tooltip will say IntentSrf. Click the left mouse button to select the intent reference. Instead of picking geometry explicitly to reference, you are telling the system to reference the surfaces of the sides created by the extrusion. This is the intent reference.   After editing the definition of the draft feature so that it uses intent references to always reference the side surfaces of the extrusion, we can make changes to the extrusion’s section without problems.   We can also use intent references to redefine the rounds, removing references to explicit geometry, and substituting intent edges at the end of the extrude feature.   The draft and round features no longer reference the individual surfaces and edges of the extrude feature. Instead, the draft uses an intent reference that consists of all side surfaces of the extrude, while the round feature uses an intent reference that consists of all edges at the end of the extrude. Now we can go ahead and delete the square interface and replace it with the hexagonal interface.   With Intent References, we’re able to delete the square interface and replace it with a hexagonal interface without failures occurring.   This time everything has updated properly. The draft is applied to the side surfaces of the extrude, while the rounds are applied to the end profile of the extrude.   The bottom line is whatever we change the profile to, we’ve ensured the draft and rounds will be created properly.   Check out our video tutorial on the PTC University Learning Exchange (“Intent References”) to see this advice in action. We’d also love to hear your suggestions for working with intent references below.   For more in-depth product feature explanations, visit our Tech Tips area.   Have some ideas about what PTC Creo product features you’d like to learn more about?
