It addresses those questions we as users have been constantly striving to answer:

• How can we change our design as quickly as we change our mind?
• How can we capture ideas as soon as we think them?
• How do we thrive in a multi CAD world?
• When will CAD be so simple anyone can use it?

The great news is that we are now seeing many of the CAD software vendors actively present their tools to address these issues. But we’re being bombarded with confusing messages, nothing is clear, in fact things are confusing, everything is a shade of gray. From what we are seeing surely all these systems use Synchronous Technology.

Wrong! There is black and white. Whilst there are many 3D CAD systems available only two have Synchronous Technology those being Solid Edge with Synchronous Technology and NX, both Siemens PLM Software products.

Why the gray then? As always terminology tends to confuse the issue quite a bit. So let’s define the terms:

• History-based: features managed linearly and are dependent on each other, edits trigger regeneration of subsequent features
• Direct editing: body editing that appends a feature in a history modeller (parametric but directed from parent feature)
• Explicit editing: body editing in a non-history based system (no parametrics other than some possible dimensions)
• Synchronous Technology: feature-based, history-free modelling that offers parametrics in a non-history world

There are many systems that use history based, direct editing and explicit editing methods. Sometimes a combination of these methods may seem like Synchronous Technology. But only Solid Edge with Synchronous Technology and NX actually have Synchronous Technology.

This is what Synchronous Technology can do:

Test your own or other 3D systems to see if they can do this, and gray will become black and white.

Why not try Solid Edge with Synchronous Technology for yourself.

However all of these examples focus on the creation and manipulation of geometry within the part model itself. I now want to illustrate some of the capabilities we have with regards to making design changes directly within the assembly.

A synchronous assembly will allow us to manipulate a parts geometry using the Steering Wheel, PMI dimensions and Live Rules, all without the need to in place edit the component. This ultimately speeds up the design process for us since we can make modifications to multiple part simultaneously.

The video below will demonstrate these capabilities but first of all I would like to set the scene…

The scenario is that we have a partially completed design of a garage door opener. A supplier who uses a different 3D CAD product (this could be SolidWorks, Inventor or any other 3D CAD application) has designed a couple of parts and sent them to us in order to be used in the final assembly. Once we have brought them into our design we then find out they need some modifications in order to fit and function correctly. In the past this would have involved getting our supplier to make the required changes and re-sending the new files. This of course would have a lengthy turnaround time associated with it as well as certain communication barriers that may need to be crossed. This would not be the case If we used Solid Edge with Synchronous Technology, these changes can be implemented in minutes rather than days as we shall see below.
