Solid Edge Synchronous Technology represents a fundamental shift in how engineers approach 3D modeling by combining the speed and flexibility of direct modeling with the control of parametric design. While traditional history-based modeling relies on a rigid linear progression, Synchronous Technology allows you to interact directly with the geometry, making it the best choice for rapid design iterations and multi-CAD environments.
To get the most out of your workflow, here are the best practices for mastering Solid Edge Synchronous Technology. 1. Master the Steering Wheel
The Steering Wheel is the heart of synchronous interaction. It is the primary tool for moving, rotating, and offsetting faces or features.
Re-center with the Origin: Click the center knob to move the wheel to a specific edge or vertex.
Orient for Precision: Use the directional axes to constrain movement to a specific plane.
Tilt for Angles: Click the torus (the outer ring) to rotate geometry around a specific axis. 2. Leverage Live Rules
Live Rules is the "intelligence engine" that maintains design intent without the need for complex sketches or constraints. It scans the model in real-time to find geometric relationships.
Maintain Symmetry: Enable the symmetry rule to ensure that edits on one side of a part are mirrored automatically.
Align Coplanar Faces: Use this to move multiple faces at once, even if they aren't physically connected.
Toggle on the Fly: Use keyboard shortcuts (like 'V' to suspend rules) to make quick, non-standard adjustments without diving into menus. 3. Prioritize Face Selection Over Sketching
In a synchronous environment, the 3D face is more important than the 2D sketch. Once a sketch is extruded, the dimensions migrate to the 3D model.
Direct Interaction: Instead of editing a sketch, select the face of the 3D feature and drag it.
Selection Manager: Use this tool to quickly grab "all similar holes" or "all boss faces" to make global changes in seconds. 4. Utilize PMI for Dimensional Control solid edge synchronous best
Product Manufacturing Information (PMI) isn't just for documentation; in Synchronous Technology, it is a primary modeling tool.
Driving Dimensions: Apply PMI dimensions directly to the 3D model to lock in specific values.
Directional Control: Use the red/blue arrows on a PMI dimension to decide which side of the geometry should move when the value changes.
Locked vs. Unlocked: Lock a dimension to ensure it stays constant during other global edits. 5. Seamless Multi-CAD Editing
One of the best features of Solid Edge Synchronous is its ability to treat "dumb" geometry (STEP, IGES, or Parasolid files) as if it were native data.
No History Needed: When importing a file from another CAD system, Synchronous Technology recognizes holes, rounds, and patterns automatically.
Feature Recognition: Use the "Recognize Holes" command to turn static cylinders into editable hole features with standard thread data. Summary of Best Benefits
Speed: Edit models up to 100x faster by skipping the "regenerate" wait times.
Flexibility: Change your mind at any stage of the design without breaking the model tree.
Cleanliness: Reduce the "clutter" of complex parent-child relationships that plague traditional modeling.
🚀 Key Takeaway: Synchronous Technology is at its best when you stop thinking about how you built the part and start focusing on what you want the part to be right now.
To help you apply this to your specific projects, what industry are you designing for or what specific modeling challenges are you currently facing? Synchronous is uniquely powerful in sheet metal:
The Shift in Modern CAD: Why Solid Edge Synchronous Technology Wins
For decades, engineers were forced to choose between two rigid paths: the structured, history-based world of Ordered modeling or the flexible but "dumb" world of Direct modeling. Siemens broke this dichotomy with Synchronous Technology (ST) in Solid Edge. It isn’t just a feature; it’s a fundamental shift in how geometry is calculated, combining the best of both worlds into a single, fluid workflow. The Power of "History-Free" Intelligence
In traditional CAD, if you want to move a hole at the end of a design process, you have to hope the "parent" features don't break when the model regenerates. Synchronous Technology eliminates this "feature-tree" anxiety.
By using a steering wheel (a 3D manipulator) and Live Rules, the software recognizes geometric intent on the fly. If you move a face, Solid Edge detects that it is part of a symmetric pattern or co-planar with another surface and maintains those relationships automatically. You get the speed of direct editing without losing the precision of parametric design. Unmatched Multi-CAD Flexibility
One of the biggest headaches in engineering is working with "dead" geometry—files imported from Step, Parasolid, or competitive software like SolidWorks. In a traditional environment, these files are a nightmare to edit because they have no history.
Synchronous Technology treats imported data exactly like native data. Because it recognizes geometric relationships (like tangency and concentricity) instantly, you can modify a supplier's part as easily as if you had built it yourself. This makes Solid Edge the ultimate tool for companies operating in a multi-CAD ecosystem. Design Iteration at the Speed of Thought
The real "best" of Synchronous Technology is felt during the conceptual phase. Design is rarely linear. When a client asks for a major structural change late in the game, Synchronous allows you to grab a set of faces and stretch them without waiting for the entire part history to recompute.
This leads to a massive reduction in "rework" time. Engineers can focus on the function of the part rather than the math of the feature tree. By blending this with the ability to still use "Ordered" modeling for complex surfaces when necessary, Solid Edge offers a hybrid environment that no other CAD package has quite replicated. Conclusion
Solid Edge Synchronous Technology is the "best" because it removes the technical barriers between an engineer’s idea and the digital model. It provides the predictability of constraints with the freedom of direct manipulation, ensuring that your CAD software works for you, rather than you working for your CAD software.
Are you looking to transition an existing library of ordered parts to synchronous, or are you starting a fresh project from scratch?

In the world of 3D CAD, there has historically been a trade-off between the speed of direct modeling and the control of parametric, history-based design . Siemens Solid Edge bridged this gap with Synchronous Technology (ST), a modeling paradigm that allows designers to edit geometry directly without being tethered to a rigid feature history .

Open an assembly. Insert a new part. Instead of sketching on a plane, right-click a face on the adjacent part and select "Create Part in Context" .
In the world of 3D CAD, a dogmatic war has raged for decades. On one side, you have History-Based (Ordered) modeling—the "recipe" approach where every feature relies on the one before it. On the other, you have Direct Modeling—the "clay" approach where geometry is pushed and pulled without regard for history.
For years, engineers were forced to choose: The flexibility of design intent (History) or the speed of editing (Direct).
Solid Edge Synchronous Technology did not try to pick a winner. Instead, it merged the two into a singular, integrated environment. It is widely considered the "best" implementation of this hybrid technology not just because it works, but because it allows the user to toggle between these mindsets mid-stream, without losing data or intent.
Here is a deep feature breakdown of why Synchronous Technology stands alone.
Synchronous Technology is not a "mode" you occasionally switch on—it's a hybrid modeling engine that combines the best of explicit (direct) and parametric (history-based) modeling. It is best for specific workflows and design challenges.
Here is where Solid Edge with Synchronous Technology delivers the most value:
The primary reason Synchronous is superior lies in its mathematical foundation. In traditional history-based CAD (like SolidWorks or Inventor), a hole is defined by its placement on a face. If you delete the face, the hole breaks.
In Synchronous Solid Edge, geometry is persistent. When you create a face, it is stored as a geometric entity. When you move that face, the system uses Live Rules to determine what sticks to it and what stays behind.
Why it’s the best: It solves the "Daddy, where do babies come from?" problem of CAD. You don't need to know the parent-child relationships of the model to edit it. If you want to move a boss, you grab the face and move it. The underlying solver handles the logic automatically.
