Sketch Solver 2.0 is the latest version of the powerful parametric sketch constraint solver and 2D CAD geometry engine developed by TopSystems (now integrated into T-FLEX CAD ecosystem and available as a standalone solver module or API). This advanced tool specializes in solving complex 2D geometric constraints, creating fully parametric sketches, and driving precise 2D geometry for mechanical design, fixture design, layout planning, and manufacturing preparation. Sketch Solver 2.0 delivers lightning-fast constraint resolution, robust handling of over-constrained/under-constrained conditions, intelligent auto-constraint inference, and seamless integration into CAD systems for real-time parametric editing. It is ideal for engineers requiring high-performance 2D parametric modeling, automatic dimensioning, and geometry optimization in mechanical, automotive, tooling, and product design workflows.

Key Features of Sketch Solver 2.0

• High-Speed Constraint Solving: Extremely fast geometric constraint solver using advanced mathematical algorithms; handles hundreds of constraints and entities in milliseconds even in complex sketches.
• Intelligent Auto-Constraint Detection: Automatically applies coincident, parallel, perpendicular, tangent, equal length, symmetry, and other relations based on user intent; reduces manual input while maintaining design intent.
• Robust Over/Under-Constrained Management: Clear diagnostics for over-constrained (redundant) or under-constrained (free) conditions; drag-to-solve interactive mode and constraint relaxation tools for easy resolution.
• Parametric & Variational Design: Full support for dimensional, geometric, and relational constraints; variables, equations, and tables for driving geometry changes; supports design tables and family parts.
• Advanced 2D Geometry Tools: Precise creation and editing of lines, arcs, circles, splines, ellipses, offset curves, chamfers, fillets; powerful trimming, extending, breaking, and mirroring commands.
• Dimensional & Annotation Control: Automatic and manual dimension placement with associative behavior; geometric tolerances (GD&T), surface finish symbols, and text annotations fully linked to geometry.
• Integration & API Support: Embeddable solver engine (used in T-FLEX CAD and other systems); open API for custom integration into third-party applications; export to DXF, DWG, and STEP formats.
• Performance & Usability Enhancements: Optimized for large sketches; modernized UI with intuitive drag-and-drop constraint application; improved stability and error recovery for production use.
