The PTC Creo Parametric vs. Pro/ENGINEER Wildfire 5.0 blog series has covered areas such as cross sectioning, measuring geometry, sheet metal, assembly performance, 3D annotations, and a new user experience.
In our final installment, I will discuss the Freestyle modeling capabilities which are available in every base license of PTC Creo Parametric. Freestyle makes working with freeform geometry significantly faster compared to Pro/ENGINEER Wildfire 5.0. Here’s how:
1) Subdivisional Modeling
This is the core technology behind Freestyle modeling in PTC Creo Parametric. You start with a simple shape such as a sphere, plane or cube and then manipulate it using a control mesh. You can move vertices, edges, faces while maintaining smooth geometry throughout the entire design. Edges and faces can be extruded, split or connected to subdivide the control mesh and add more controls to the shape. All of these changes are done with a few quick clicks of the mouse.
Freestyle modeling also allows you to set up symmetrical features with ease. This way, any change to one side of the control mesh will be reflected on the other automatically.
Creating freeform geometry this way is simply not possible in Pro/ENGINEER Wildfire 5.0. To achieve similar results would require significant time and sophisticated design expertise.
2) Multi-level Subdivision
This capability allows you to divide the control mesh into smaller sections and edit finer details without having to change the overall structure and shape of the entire geometry.
With Pro/ENGINEER Wildfire 5.0, many of these changes would have to be built into the original design intent. You would then have to select each section and edit the surfaces individually.
3) Adding Details
The result of a Freestyle feature is a regular PTC Creo Parametric quilt. As such design features can be added with a few simple clicks – this includes holes, bosses, fillets, chamfers and ribs. The geometry can be easily thickened or turned into a solid part. The size and shape of the features are easily modified by dragging the mouse.
Again, with Pro/ENGINEER Wildfire 5.0 these changes would require more commands, time, and effort.
The speed and ease of Freestyle modeling makes it ideal for the concept design phase. You can quickly test ideas and explore what-if scenarios in a matter of hours as opposed to days.
However the real benefit is that all of these efforts are completed in the context of PTC Creo Parametric and the data can be fully re-used in the detailed design phase all the way to manufacturing
A third-party benchmark calculated that users could accomplish similar design tasks up to 92% faster using Freestyle modeling in PTC Creo Parametric compared to standard tools in Pro/ENGINEER Wildfire 5.0. Freestyle modeling is just one reason to make a move. Have a look at this head to head comparison video to see all the changes for yourself:
