:: Prescient Technologies

Essence is a solid modeler developed by Prescient.

Topology:
- B-Rep: Boundary representation of solid and surface models
- Wire-Frame: For curves
- Mesh: for triangular meshes
Geometry:
- Curves:
  Line, Circle, Conic, Bezier, B-spline curves and
- Algorithms:
  curve projection, curve-curve intersection, area under curve, curve extension, curve interpolate, least square curve fitting, degree elevator, degree reducer, merge spline, Lagrange-solver, knot removal, knot refinement.
- Surfaces:
  Planer, cylindrical, spherical, surface of linear extrusion, surface of revolution and algorithms like surface projection
- Algorithms:
  Surface-Surface intersection, Lagrange-solver, least square surface fitting, merge surfaces, single surface fitting.
Operators
- Extrude, Sweep, Revolve, Loft, Booleans, Shelling and/or thickening,
  Blend, Extrude cut, Stitch, Curve creators, Water tight Tessellation, Transformation
Sketch Fitting
- Sketch fitting fits sketch entities with auto constraints.
- Sketch fitting detects line, arc, bspline from given points and create sketch.
Constraint Solver
- Constraint solver handles 2D and 3D constraints.
- It supports 2D constraints like horizontal, vertical, parallel, perpendicular, parallel with value, angle with value, tangent, coincident, concentric, distance, linear, radial, collinear, equal length radius, co radial etc.
- It also supports 3D constraint like axial align, parallel, perpendicular, distance etc. User can add, modify, and delete constraints and entities.
