Industrial Designers: Try These New Features in Creo 4.0
by Cat McClintock | June 14, 2017 | CAD Software Blog | PTC
Industrial designers need to create touchable surfaces with ease and agility. That’s why the recent update to our powerful 3D CAD software platform—Creo 4.0—includes a bunch of enhancements that can help designers create products so attractive that they fly off the shelf.
So where do you start? Product Management Director, Mark Fischer, suggests every industrial designer look specifically in these 3 different areas of Creo Parametric: Freestyle, Style, and rendering.

Freestyle – Complex geometry made easy
When you’re creating unique and aesthetically pleasing designs, Freestyle Modeling in Creo Parametric gives you the freedom to quickly create freeform shapes and surfaces. Fischer points out a few notable enhancements related to freestyle modeling that make the application more powerful and easier to use.
First, Creo 4.0 boasts support of N-Sided (N-Gon) faces in Freestyle. Fischer says, “Traditionally, when you create a freestyle feature, you create your surface geometry using a sub-divisional control mesh. Each face of the mesh has four sides, called a quadrilateral face.” Now, you can split quad faces into faces with less than or greater than four edges. This functionality increases the definition of each face in control mesh, and it provides better control when you’re defining the freeform surface. Fischer says, “This means users can now create more complex surface geometry using fewer steps.”
In Creo 4.0, quad faces can be split into n-sided faces.
Plus, you can now import standard Wavefront (*.obj) files into Freestyle. So you can import the full fidelity of a file created using another application into Freestyle. See how it works:
Finally, you can manage multiple disconnected objects in a freestyle feature. You can easily edit and manipulate each individual object. For example, you can:
- Join and connect entities from different shapes
- Split a shape into multiple shapes by slicing along a set of edges or faces
- Duplicate shapes
- Hide and unhide shapes
- Lock shapes
Curve handling functionality enhanced in Style
Style now includes curve handling functionality that you’re used to using in other areas of Creo Parametric.
In Creo 4.0, we enhanced closed loop curve handling functionality. A closed loop curve is a curve that joins itself. When you create a closed loop curve, the system automatically defines it as a periodic (smooth) curve. Nonperiodic (irregular/jagged) curves were the default type defined in Style in previous releases. You change the definition of a periodic curve to define it as a nonperiodic curve by using the new toggle option that’s available on the Curve dashboard.
When you create a closed loop curve in Creo 4.0, it is automatically defined as a periodic (smooth) curve.
Additionally, within Style, PTC enhanced Drop Curve functionality. Use this feature to add curve geometry onto a surface, as shown below.
On the left, the curve is projected using the Along direction option. On the right, the curve is projected Normal to surface.
The dropped curve on the datum plane converts the curve to a planar curve. When dropping a curve on a surface, you can flip the direction. This enhanced functionality reduces the need to create additional geometry and makes it easier to define shapes and project them.
Finally, you can easily create high-quality surfaces and see how they transition using acceleration connections (G3). In Creo 4.0, define a new acceleration connection between two surfaces. For example, you can define a connection between two curves, a curve and a surface, or a curve and an edge. An acceleration connection shows the rate of change of curvature across the boundary. Here’s how to set up this type of connection:
Fischer says, “Historically, we had tangent (G1) connections and curvature (G2) connections, but now in Creo 4.0 we also offer acceleration (G3) connections.”
Rendering – New Photo-Realistic Rendering application now available
Creo 4.0 now includes more powerful graphics and rendering capabilities too, says Fischer.
Note that you won’t see the Rendering tab in Creo 4.0 anymore. Core elements (such as Scenes, Appearances, and Perspective View) from the Rendering tab moved to View tab. Fischer says, “Moving these rendering functions to the View tab means these are now core capabilities that are available to all Creo Parametric users.” As a result of these changes, the Shade with Reflections option now appears in View tab—no special add ons or extensions needed.
Core elements (such as Scenes, Appearances, and Perspective View) from the Rendering tab now reside in the View tab.
A new Photo-Realistic Rendering application replaces the former Creo Advanced Rendering Extension. You can reach this new application from the Applications tab in Creo Parametric. You can easily switch between rendering and modeling without exiting the rendering application. Plus, you can now use powerful Real-Time Raytracing, powered by Luxion Keyshot.
Finally, even if you haven’t purchased the new rendering application, you still can create really good rendered images using our out-of-the-box Shade with Reflections feature.
Create touchable surfaces with Creo 4.0
As you can see, the intuitive and streamlined surface modeling workflows available in Creo 4.0 help simplify your product design work. Plus, powerful new rendering capabilities can bring your work to life. Are you ready to try it out? To learn more, or to download a free 30-day trial, visit the Creo 4.0 page today.
