Zoom and frame the view
Inspect a detail, fit the drawing, or frame a rectangle in the 2D plan.
Use the wheel, keyboard, canvas Zoom menu or status-bar zoom dropdown. The 2D plan also has a zoom-window tool. Changing view scale does not resize the design geometry.
Zoom toward the pointer
Scroll over the canvas to zoom toward the point you are inspecting. Move the pointer away from side panels so the event goes to the canvas. In the plan, horizontal wheel input or Shift-scroll pans instead of performing ordinary vertical zoom.
Fit or reset the view
Ctrl+0 invokes fitting; the Zoom menu also offers a fitting action. Use Home for the default framed view. Ctrl+1 invokes the 1:1 zoom action; it is not a guarantee that a perspective 3D scene has a physical one-screen-pixel scale.
Frame a 2D region
Press Z in the 2D drawing and define the zoom window using its pointer prompts. The view frames the chosen region. Use V to return to Select or Esc to cancel the current zoom-window step.
Use zoom buttons or presets
Ctrl++ and Ctrl+- step in and out. The status-bar dropdown provides zoom and fitting actions. Percentage presets are displayed in the 2D plan; the 3D control is labeled Zoom instead of showing an orthographic percentage. Ctrl+= also zooms in on layouts where the plus key shares the equals key.
