2D offset profiles and profile based geometric constraint solving

Integrating the PGM (Profile Geometry Manager) into your software application provides a range of offset profile and geometric constraint solving operations, see the PGM capabilities listed below. Target applications include:

• 2D and 3D CAD systems
• 2D toolpath creation in CAM systems

Flexible licensing arrangements and a simple, proven integration process enable your organisation to add PGM capabilities to your applications quickly and economically.

For a step-by-step description of how the PGM is used in an application, view our product tour, or request your own demo application or technical overview.

PGM: Key Capabilities

• Supports points, lines, circles, ellipses, splines, general parametric curves, and offset curves
• Automatically creates valid 2D offset profiles
• Trims zero length offset edges, zero radius offset arcs, overlapping and intersecting offset edges.
  View Animation
• Cap gaps in the offset profile by extending the adjacent edges or by inserting new edges
• Trims intersecting and self-intersecting offset ellipses and splines.
  View Animation
• Measures profile properties, including length and area

Integrating the PGM with the 2D DCM provides these additional capabilities:

• Solves dimensions and constraints to profiles.
  View Animation
• Constrains profile properties, including length and area.
• Maintains a valid offset profile in response to 2D DCM driven parametric design modifications.
• Handles changes in offset profiles, such as edge reversals.

• Ensures that dimensioning schemes are preserved even when edges are trimmed.

• Operations are non-sequential, hence more flexible. Dimensions and constraints can be added to any combination of geometries in the base and offset profiles. The base profile can drive the offset profile and vice versa.
