2D Geometric Constraint Solving for 2D and 3D Applications, Including Parametric Modeling

Integrating the 2D DCM (Dimensional Constraint Manager) into your software application provides a geometric constraint solving capability that enables your end-users to create and modify 2D sketches more efficiently.

The 2D DCM’s driving dimensions (parameters) and geometric constraints specify the location of the geometries in 2D sketches. End-users can modify their designs by changing dimension values or dragging geometry. The 2D DCM maintains the design intent by ensuring that the dimensions and constraints are satisfied.

The 2D DCM provides the geometric constraint solving in most popular parametric modeling systems and many other applications. See our list of application areas for more details. Our large customer base, with more than three million end-users, drives investment in quality and functionality over the long-term.

2D DCM Capabilities:

• Constrain 2D geometry, including points, lines, circles, ellipses, splines and general parametric curves.
• Use a wide range of geometric constraints, including parallel, perpendicular, tangent, concentric, normal, midpoint, symmetry, linear/radial pattern, equal distance and equal radius.
• Apply driving dimensions to define/modify a 2D sketch: distance, angle and radius.
• Add various geometric constraints to freeform curves, including spline length, tangent direction, tangent length, second derivative, equal direction and equal curvature. View Animation
