Parametric Constraints
Geometric constraints
Constraints capture relationships such as coincident, horizontal, vertical, parallel, perpendicular, equal, tangent, distance, angle, and radius. Use the degree-of-freedom and conflict indicators to understand the sketch state.
Editing constrained geometry
Moving or grip-editing constrained geometry can move neighboring objects. If a solve fails or becomes redundant, inspect the constraint glyphs and conflict status before deleting geometry.
Persistence and history limitations
Constraint data is stored as OpenCAD Studio extension data inside DWG and DXF. Other applications may preserve it without interpreting it. Constraint edits and geometry changes may currently occupy adjacent history entries; verify the result after undo, redo, erase, copy, and reopen operations.
