Workspace and Navigation
Model space and paper space
Model space is the primary drawing environment. Paper-space layouts arrange views for plotting through layout viewports. Always confirm the active space before drawing or editing.
Pan, zoom, and orbit
Use pan and zoom to navigate without changing drawing geometry. Use orbit and view controls for three-dimensional inspection. Zoom Extents is useful when the drawing appears empty or geometry is far from the expected location.
Multiple model viewports
Model viewports can show different views of the same document. Grid, snap, camera, and render mode may vary by viewport; confirm which viewport is active before entering coordinates.
Selection and object snaps
Selection identifies the objects a command will modify. Object snaps target precise geometric locations such as endpoints, midpoints, centers, and intersections. Zoom in and verify the snap marker when precision matters.
