OpenCAD Studio User Manual
Create and Edit Geometry
Basic drawing commands
Create lines, arcs, circles, ellipses, polylines, splines, points, text, hatches, and other supported entities from the ribbon or command line. Follow the active prompt: multi-step commands remain active until they complete or are cancelled.
Modify geometry
Common modification workflows include move, copy, rotate, scale, mirror, offset, trim, extend, fillet, chamfer, stretch, join, explode, and erase. Locked layers can prevent modification.
Grips and direct manipulation
Select an entity to expose its grips. Dragging a grip previews and then commits a geometric change. Constrained neighboring geometry may update with it.
Undo, redo, and OOPS
Undo reverses recorded document operations and Redo reapplies them. OOPS restores the most recently erased entities without reversing later commands. Save before a risky sequence and verify that associated dimensions, hatches, groups, and constraints were restored with their geometry.
