Solid Edge ST3 – Post 3 of 4

As Promised, here is my 3rd post on Solid Edge ST3’s customer driven enhancements. This time, the topic is Piping, Framing, and Weld enhancements.
Let’s start with Frames. Frames are made up of 3 items for each frame member: The sketch defining the path, the cross section defining the shape, and the resulting member as a solid model. With ST3, some work was done with the cross sections to add additional attachment points which are used to attach the cross sections to the paths. In addition to the prior default of the geometry Range Box showing the 8 points defining the rectangular extents boundary around the shape and the center point, you can now define the cross section’s path attachment point by using key points (end/mid/center/etc.) on the cross section’s defining sketch (including reference elements) or the cross section’s area centroid.

In addition to the new locating methods, cross sections are now associative to the members that they have defined (so changes to the cross section in the library updates the solid model in the Frame assembly) and also support specifying WurzelmaƟ standard hole locations (DIN Standard). If you don’t know what WurzelmaƟ means, you’re not alone.  It’s German, and it’s literal translation is “Back Pitch” in English.  It has been explained that it is the allowable location on flanges where holes may be placed.

Piping has a few enhancements specific to it as well. Pipe fittings can now be graphically rotated.

Pipe gradients are now supported for drainage situations. Fittings will tolerate a specified deviation from the standard fitting angle to allow for the specified gradient.

In prior releases, pipe fittings were required to be added to the Standard Parts library to be used. That requirement has been lefted and now pipe fittings can now be placed directly from disk or managed environments (Insight/Teamcenter).
Both environments have benefitted from the new ability to pattern Pipe or Frame components.

Parts Lists now support “per item” and “cumulative” mass for pipe/frame components and the mass calculation accounts for removed material in mitres and assembly features. Mitre cut angle can also be included in the parts list as well.

In Welding, a new algorithm has been introduced that produces weld beads that support many more geometric conditions, exactly matches input faces to eliminate interference, and also transition smoothly around sharp corners.

As I stated before, this is just a subset of user requested enhancements. There is a lot more that I cannot publish yet, not to mention we haven’t touched on new features or the “Bridge”. Stay tuned, more to come soon.
