OpenCAD Studio User Manual
Getting Started
What OpenCAD Studio does
OpenCAD Studio is a desktop and web CAD application for opening, creating, editing, visualizing, and saving two- and three-dimensional drawings. It works with DWG and DXF drawings and provides command-line, ribbon, automation, and plugin-oriented workflows.
A first drawing
- Create a new drawing or open an existing DWG or DXF file.
- Confirm the active workspace, units, layer, and object-snap settings.
- Create geometry with a drawing command such as Line, Circle, or Polyline.
- Edit the result with grips or a modification command.
- Save the drawing under a new name until its compatibility has been verified.
Data safety: Keep an untouched copy of important third-party drawings. Confirm geometry, layouts, external references, and plotted output before replacing the original file.
How to use this manual
Use the chapter navigation for broad workflows, the search box for a command or concept, and the previous/next links for sequential reading. Command names, system variables, keys, and file extensions appear in monospaced text.
