CAD

PTC Mathcad is an ideal tool for recording the design knowledge for many different engineering problems. As engineering problems get more complex, the design knowledge grows in length and so does the Mathcad worksheet. The longer the Mathcad worksheet, the more regions it contains and for very large worksheets that contain hundreds of regions the general performance of document operations can become an issue. This is something that a number of customers have raised as an issue with Mathcad Prime and is something we want to address.For the last year, while PTC Mathcad Prime 3.1 functionality was being implemented, our development team has been working on refactoring how PTC Mathcad worksheets are structured and displayed in an attempt to greatly increase the performance of larger worksheets. Operations like adding lines and pages of space, opening and closing areas, changing page formatting options, copy and pasting content – the general functionality we all use when navigating a Mathca

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, t

Welcome to the first edition of our new blog series “Fast Facts!” This content is intended to provide users with easy-to-use, actionable tips and tricks for how to use PTC Creo more effectively. Today, we will focus on a few commands to help you become more effective in part modeling mode. These tips come from Steve Meyers and Evan Winter, two PTC Creo experts in our training group.   1. Using Intent References   You can increase the robustness of features using Intent References, which capture the intent of the feature when selecting resulting edges or surfaces (the edges bounding a surface of a feature, or a set of extruded vertices).     1. Query Select to Intent References, or use “Pick from List” in RMB while creating Rounds, Chamfers, Draft, etc.       2. Notice, there is no failure after base feature modification     Learn more about Intent References in our Did You Know Blog Post   2. Showing Feature and Component La

Our weekly Did You Know series focuses on providing users with informative, “how-to” tips to help them get the most out of PTC Creo. This week’s post, provided by Director of Product Management Paul Sagar, shows users how to create family tables in PTC Creo Parametric. Users will learn how family tables enable you to create a large number of common parts quickly, based upon a generic design model.   Family tables are a collection of parts or assemblies which are similar, but deviate slightly in some aspect – such as size or included features. Bolts are a common example because they look similar and perform the same function regardless of their properties. It’s helpful to think of them as a family of part models. Parts in family tables are also known as table driven parts. In PTC Creo Parametric, you can create family tables in three easy steps.   Step 1: Identify Features Which Will Vary First, you must identify which dimensions or features will vary for your family of parts.

PTC Creo 3.0 introduces a new Align capability within Freestyle which allows PTC Creo Parametric users to create and drive freeform, stylized designs parametrically. Users can now connect their Freestyle geometry to other external geometry with positional, tangent, or normal conditions. Furthermore, any change made to this external geometry will be reflected in the Freestyle geometry during regeneration.   Paul Sagar, Director of Product Management, gives us an introductory overview of the new Align feature:   PTC Creo 3.0 introduces a new “Align” feature within Freestyle. With this capability, you can align the freestyle control mesh to external curves and edges and therefore parametrically control your freestyle geometry.   In this example, we will be working on a bike model and building the surfaces around the pedal. These surfaces are defined parametrically by the neighboring geometry. We will start with a sphere, and build out the geometry to get it close to the nei

Our weekly Did You Know series focuses on providing users with informative, “how-to” tips to help them get the most out of PTC Creo. This week’s short post shows users how to create a square to round blend in PTC Creo Parametric, the source of inspiration for this tutorial originally came from a member of our PTC Creo Community. Users will learn how to create the blend in 3 steps.   Step 1: Sketch a Square Section You have two options when creating a blend; you can either sketch the sections ahead of time and select them in the blend tool, or you can sketch the sections within the tool as you create the blend. In this example, you will create external sections and select them in the Blend tool.   Begin by creating a square section on your first sketch plane with the Center Rectangle tool in Sketcher. Sketch a Square Section     Step 2: Sketch a Circular Section and Divide it Create a second sketch plane offset from the one on which you sketched your square section

Our weekly Did You Know series focuses on providing users with informative, “how-to” tips to help them get the most out of PTC Creo. This week’s post, provided by Product Management Director Jim Barrett-Smith, is a brief, introductory overview of routing cables inside the PTC Creo Parametric Piping and Cabling Extension. Users will learn how to filter logical cables, add locations to axis, and understand how the next location in a wire segment will be created. Tip 1: Filtering Logical Cables First, select Route Cables under the Cabling section of the user interface. In the Route Cables dialog you will notice there is a Find tool. This will find all the wires and cables with logical references. If this is a very large list, you can refine it by simply selecting a designated component from the graphics area. When you select a designated component, the wires that attach to it are added to the Route Cables dialog. If you hold control and left click, you can select multiple components &nbs

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

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

We’re happy to announce the first edition of our “Did You Know?” series here on the PTC Creo Community, providing you with informative, “how-to” tips to help our members get the most out of PTC Creo Parametric.   Today we’re sharing three expert tips, provided by our Director of Product Management  Paul Sagar, on creating advanced round geometry inside PTC Creo Parametric:   Putting a Round on 3 Edges – You can control the specific geometry at the transition of 3 edges.  Go to the main dashboard and click on the “Pieces” menu. From here you can hover over each individual piece and the software will highlight the geometry created. You can “include” or “exclude” specific pieces to control the overall geometry. See Image 1 below: Image 1: Rounds on 3 edges   Creating a Blended Transition Between two different rounds – By default, when you select an edge it automatically rounds the tangent chain. By holding shift, you can create a round on just one specific edge.
