So many welds, so little time… and that’s how long it takes to create them using NX Weld Assistant… very little time.

In addition to the weld types shown in the image above, you have the option to create custom weld types giving you the ability to model any type of weld possible.

One type of custom weld is an extension weld. This type of weld is started and stopped beyond the limits of the parts being welded as seen in the image below.

To create this weld, we will simply create a line weld in the usual way (see image below) and then use synchronous modeling + move face to grab and extend the face that makes up each end of the weld.

Key benefits to modeling welds in Cad include:

  • Provides a key piece of information necessary for a complete Digital Twin.
  • Mass properties inclusion (Weight and Volume).
  • Easy to visualize.
  • Easy to validate for correct location using Weld Advisor.
  • Easy to convey information via a Drawing or PMI
  • Available for inclusion into CAE analysis
  • Available for process planning
  • Available for robot programming
  • Significant time savings compared to manual application of welds
  • Having the ability to create and validate the welds in CAD ensures quality data is being sent to manufacturing thereby reducing the amount of rework.

There is so much more to this command than welding. Not only is there a full range of weld types, but you can also model beads of adhesives, glue, and mastic as well as fasteners like rivets for example. Basically there are three categories in Weld Assistant for joining parts, they are: discrete welds, line welds, and adhesives. Normally a rivet is a type of fastener, but they are included as a custom weld in Weld Assistant.

In this post, let’s take a look at how to model rivets. We will create a custom spot weld to mimic a rivet. We will start by configuring a custom weld spot under File + Utilities + Customer Defaults.

  • From the Customer Defaults window, select Weld Assistant + Point Locator and then select one of the Custom tabs.
  • Set the Solid Display to Cylinder and give the custom Point Locator a name… Rivet for example.
  • Set the other attributes accordingly, and then select OK to finish the configuration.

Now create a Rivet the same way you would create a Resistance Weld Spot.

  • From the Weld Assistance command select Weld Point Wizard.
  • From the Weld Point Wizard block:
    • Select your Method
    • Set the Type to the new custom Point Locator you just created (i.e. Rivet)
    • Select Next.
  • Select the Face Sets and then select Next
  • Select the points you want to create Rivets at and then select Next.
  • Select Finish to place the Rivets.

If the Rivets don’t show up at first, then select the Solid Weld Point Display option.

  • Provides a key piece of information necessary for a complete Digital Twin.
  • Mass properties inclusion (Weight and Volume).
  • Easy to visualize.
  • Easy to validate for correct location using Weld Advisor.

Product and Manufacturing Information (PMI) consists of non-geometric data, that is attached directly to a 3D CAD model to define geometric dimensioning and tolerancing (GD&T), engineering and manufacturing specifications, dimensions, and text.  PMI is part of Model Based Definition (MBD) and together these two elements are a part of a Digital Twin.

Applying PMI to a 3D model can reduce or eliminate the use of 2D drawings and can be used downstream to perform tolerance analytics and coordinate-measuring machine (CMM) inspection.

PMI is a command within NX that gives you the ability to create/attach dimensions and annotations to define the 3D model, and requires model views similar to the views on a drawing.  These dimensions and annotations are associative to the 3D geometry, and if it is decided that a 2D drawing is required, then the PMI can be inherited from the 3D model and automatically applied to the drawing views.

We think of MBD and PMI as new technologies and 2D drawings as “old school,” but there are valid uses for a 2D drawing.  Given the ability in NX to quickly create 2D drawings with associative dimensions inherited from the 3D PMI… this gives you the best of both worlds.

The image below demonstrates what PMI looks like in a 3D model view, and the next image down demonstrates the inherited PMI in a 2D drawing view:

NX Realize Shape is a powerful and intuitive subdivision design tool that makes use of primitive shapes to create concept design models.  In the image below you can see a sphere has been chosen, but there are a number of other shapes to select from such as cylinder or block to name a few.

These primitive shapes can be placed over top of background data like sketches or even art work similar to what you see in the image above.  When a primitive shape is created, a cage is automatically created that surrounds the shape.  The shape can be morphed into designs by transforming that cage.  By selecting on, and dragging the cage elements (lines or points), you can mold the shape to fit the background image.

 

As seen in the image above, you can split a face into smaller faces (subdivide) in order to create more cage elements. This gives you greater control of the cage anytime more detail is required in a given area of your design.

By selecting cage elements (lines or points) and dragging them up or down, left or right, the concept designer is able to morph a simple shape into a complex form in a relatively shorter period of time versus having to work with .

Why do we promote the use of Realize shape?

Simple, this model represents the birth of the digital twin.  This digital twin is then used for detailed design, documentation, validation, simulation, and all the way to traditional or additive manufacturing… all within a single unified environment like NX… means you are going to use trusted data from concept to manufacturing… without requiring conversion or translation, and this is going to shorten your innovation lifecycle, getting you from concept to market faster!

In Active Workspace 3.4, Siemens PLM has made some significant improvements to search capabilities. Here are some of the highlights

Numerical Range Filters

Users can now filter and narrow down search results by entering a range of values for numerical properties in the filter panel so that they  get results only in the range of what they’re have specified. For example find bolts with a length between 60 and 100 mm.  They can also use open ended ranges by leaving the lower or upper range value blank.  This is supported for both classification & object properties in both global and in-context search using  integers and real numbers.

Pre-filter for Add Objects 

Active Workspace 3.4 allows application of property based pre-filter for in-context search.  This provides a better control of allowable choices when adding related objects with the ability to retrieve context sensitive search results via configuration.  The configuration is to set a “query type” pre-filter in the XRT definition of the “Add” command, which can be based on any property value. User can always widen the scope by deactivating the filter.

Search for Business Objects based on Form Properties

Users can now search and filter on properties of Master Forms and other Forms attached to any item revision without using compound properties . Master forms are supported OOTB, other forms (including custom forms) require adding a reference to the form storage class . The properties from forms can be configured to display as Form Name.Property or  only Property . This is used in filter panel and search string syntax. This can be also used in conjunction with dynamic compound properties (DCP) to avoid making schema changes to enable search and filters for properties on related forms.

With every release of Active Workspace, Siemens PLM keeps adding more enhanced capabilities for change management process execution, Active Workspace 3.4  is no exception.

The first enhancement is a simplified overview of change that includes most relevant information pertaining to the change.  The Consolidated change overview now includes; change description, details, participants, and originating changes.  There is a new visual status bar showing change maturity progress in overall maturity process. This progress chart helps users to understand and quickly determine the change maturity.  There is also an easily accessible change summary that shows adds, removes, and replaces. The Impacted/ Solution items added or Lineage set via Active Workspace UI  or the BOM changes done via rich client from structure manager in supersedure window are reflected in the new change summary. These easy to interpret change details help users to understand the full impact of change before they make decisions on it.

The Active Workspace 3.4 relationship browser is now improved to show all associated change objects and their relationships in the interactive relations browser.  This helps users to easily understand change objects and their hierarchical relations (Implements, Implemented by, dependencies) ,   find change objects and  other business objects  relations (Problem Items, Impacted Items, Solution Items) and also relation between items (Lineage).

These new capabilities makes Active Workspace an even more preferred user interface for change management adoption.

With every release of Active Workspace, Siemens PLM keeps adding more enhanced capabilities for Schedule Manager process execution, Active Workspace 3.4  is no exception.

The most exciting Schedule Manager process execution improvement in Active Workspace 3.4 is the ability to perform a “what-if analysis”.  What-if analysis mode enables project managers to experiment on a live schedule without impacting it . This is like working with the schedule in a “sandbox” environment to perform changes  to the tasks without committing them to the production database.  This helps project managers to determine how various schedule component changes may affect the outcome of the schedule, before actually committing the changes to the schedule. Once they are satisfied with the changes,  they can promote and commit the changes to the schedule. If they are not satisfied with the outcome of the changes, then they can choose to discard the analysis.

There are also enhancements to make the Schedule Manager tool usage easier .  Now users can change the Gantt timescale using the zoom in/out feature. They can add and remove schedule deliverables, assign multiple schedule tasks to one team member using multi-select mode, add multiple tasks quickly and easily by pinning the ‘Add schedule task’ panel and also manually launch workflow on a task. These advances in schedule authoring provide project managers and coordinators greater ease and flexibility in schedule definition and maintenance.

In this age of disruptions, product development companies need to reach across the evolving business ecosystem at a rapid pace than ever, at the same time protecting  their intellectual property . Teamcenter Active Workspace enables product development companies to

  1. Reach More people by connecting more people in more places with product data and processes; both internal and external. With a light-weight, web based user interface, they can harness the power of a changing workforce to get ahead of the competition.
  2. Reach across the business processes and leverage disruption to be a market leader. Using new tools for configuring Teamcenter, they can easily adapt to change now, and in the future.
  3. Reach greater returns by finding new ways to support the business. By reducing the burden of software support and maintenance, companies can focus on driving revenue.

User experience is the key factor when it comes to reaching more people in more places. The user experience focus for Active Workspace is to provide a clean, efficient, and simple user interface that works across multiple devices and use cases, from the basic, to the more sophisticated.  Active Workspace  UI guiding principles includes
