"Synchronous Technology: A taster
posted by al dean
So, everyone's talking about Siemens and its Synchronous Technology
recently. While many are talking about it, details are scant and
everyone's guessing, but from what I have seen (and questioned the #%^
out of Siemens on) so far, I can say this: it's dammed impressive -
this technology has massive potential and will provide Siemens with
solid base for the years to come. But you kind of guessed this
already, right? Want some more details? OK - let's go.
To understand Synchronous Technology, you need to consider the
background of Feature and History-based modeling. When developed (over
20 years ago) the 3D CAD systems were not capable of solving both
Geometry and Topology at the same time, for a complete model - it was
computationally too complex.
So, the developers compartmentalised the process, split it up into a
list of features, which construct the model, which is solved in
series, one after the other. The hardware could compute each stage
more easily and output the results. These are the basics.
Systems like IronCAD, CoCreate, SpaceClaim differ in that they give
you very powerful tools for editing geometry, but don't handle
topology changes well, where faces disappear, are subsumed into other
And never the twain shall meet?
Not exactly. What the technology does is solve five things at once:
Geometry and Topology. But into this, it also solves Features, Design
Rules (or Live Rules) and Dimensions - all at the same time. this
means that editing a model, features, parameters, doesn't have such an
impact on calculation times - as there's no history to reply - the
system solves all these aspects in one go. And it's slick people, very
What else did I find out?
Productisation: Synchronous Technology will be implemented differently
in the two core modeling applications in the Siemens PLM arsenal (NX
and Solid Edge). Both development teams are co-operating on the
technology, but how it's implemented will differ between the two
product streams - and rightly so. This is a huge sea change for both
and time needs to be taken to evaluate and do the job properly - and
we all know what rushing into UI changes can do.
We're going to cover this emerging technology more and more in the
coming month as details and products emerge, but one ting is clear.
Siemens has something pretty unique on its hands and the two/three
development has paid off. Other CAD vendors rely on Siemens PLM=C2
components for its core technology (such as Parasolid and D-cubed),
but this is different in that it is an application layer in NX and
Solid Edge, these teams have no intention of giving access to this
technology and will surely squeezed every last drop of competitive
advantage out of it.
Stay Tuned - more to come..."
