Blender Edit Mode and Mesh Geometry

Cross the critical threshold from moving objects to editing their geometry. Here’s how to do it in Blender on macOS, step by step — part of the free Blender beginner curriculum.

Lesson 3 of the Blender curriculum. Next up: Core Mesh Editing Tools.

What you’ll do

• Press Tab to toggle between Object Mode and Edit Mode
• Understand the difference: Object Mode moves whole objects, Edit Mode modifies the internal geometry (vertices, edges, faces)
• Switch between the three select modes in the viewport header: Vertex (1), Edge (2), Face (3)
• Select elements with left-click; Shift+click to add; Alt+click on an edge to select an edge loop
• Box Select with B, Circle Select with C
• Select all (A), deselect all (Alt+A), invert selection (Ctrl+I)
• Move, rotate, scale selected elements using G / R / S
• Enable the Face Orientation overlay (Viewport Overlays popover > Face Orientation) and understand blue (outward) vs red (inward normals)
• Recalculate normals: select all (A) then Shift+N
• Merge duplicate vertices to fix ghost vertices: M > By Distance in Edit Mode
• Understand that Tab enters Edit Mode for the currently selected object only — Tab out first before selecting a different object

Do it hands-free with Skilly

Reading steps is one thing; doing them while the menus are in front of you is another. Skilly is a voice-first tutor for macOS: you ask out loud — “where’s the edit panel?” — and it answers while moving your cursor to the exact button, watching your actual Blender window. It’s the same Blender curriculum these lessons come from, taught live instead of read. Free to start.
