How To Achieve Class A Surface In Pro/Engineer

Class A Surface Tutorial

Class A surfaces can be achieved by satisfying two main conditions like Tangency and continuity between the curves and the surfaces.

Surface modeling is used to create design models with shapes too complex for solid features. How to use various techniques to create complex surfaces with tangent and curvature continuities whereby solids can then be created using the surfaces as references.

These following tools can be used to create the surfaces:

  • Understanding the surface modeling workflow.
  • Create basic surfaces using techniques such as Extrude, Revolve, Sweeps and Blends.
  • Create a network of curves using various techniques such as through points and sketches.
  • Create surfaces using a network of curves as boundaries.
  • Create surfaces using variable section sweep and swept blend techniques.
  • Create surfaces using advanced blend tools such as Section to Surface, Surface to Surface and Tangent to Surface.
  • Manipulate surfaces using various editing tools such as Extend, Merge, Trim and Offset.
  • Use analysis tools to check for surface quality and potential problems.
  • Create and edit solids using surfaces and quilts.
  • Surface free form
  • Surface analysis tools to check the continuity of the surfaces.

In Pro/ENGINEER Wildfire you can create freeform surface models using the interactive modeling environment called Style (ISDX).Describing the Style modeling environment.

Style is a spline-based freeform modeler that allows you to combine the parametric feature-based modeling approach with the unconstrained freeform surface modeling approach. This will give you the flexibility to design complex shaped products in a single modeling environment.

  • Creating and editing 2-D, 3-D and planar style curves.
  • Analyzing and modifying curve shapes.
  • Creating different types of style surfaces such as boundary, loft and blend surfaces.
  • Creating curves using techniques such as sketching, dropping curves on surfaces, and using the Curve from Surface option.
  • Manipulating curves and surfaces in complex models.
  • Creating continuous curves and surfaces.
  • Overbuilding surfaces using four boundaries.
  • Creating surfaces using the Create Boundaries technique.
