Blender Blender 3D Modeling 1 — Questions and Answers
Question 1: Which Blender modifier automatically mirrors geometry across a specified axis?
- Array Modifier
- Mirror Modifier (Correct answer)
- Symmetrize Modifier
- Lattice Modifier
Correct answer: Mirror Modifier
The Mirror Modifier duplicates mesh data reflected across the object's local axis, ideal for symmetric modeling.
Question 2: What does the 'Loop Cut' tool (Ctrl+R) do in Edit Mode?
- Cuts the mesh along a face diagonal
- Adds a new edge loop around a cylinder of faces (Correct answer)
- Deletes a selected edge loop
- Bevels all edges
Correct answer: Adds a new edge loop around a cylinder of faces
Ctrl+R inserts a new edge loop by splitting a ring of quads that runs around the mesh.
Question 3: In Blender's Edit Mode, pressing 'E' extrudes selected geometry. What does 'Alt+E' do?
- Extrudes along normals
- Opens the Extrude menu with multiple extrude options (Correct answer)
- Extrudes faces individually
- Extrudes only vertices
Correct answer: Opens the Extrude menu with multiple extrude options
Alt+E opens a menu offering choices like Extrude Faces, Extrude Vertices, Extrude Along Normals, etc.
Question 4: What is a 'Subdivision Surface' modifier primarily used for?
- Reducing polygon count
- Smoothing and adding resolution to low-poly meshes (Correct answer)
- Creating hard-surface bevels
- Generating UV seams
Correct answer: Smoothing and adding resolution to low-poly meshes
The Subdivision Surface modifier recursively divides faces to create smoother, higher-resolution meshes.
Question 5: Which selection mode in Edit Mode allows you to select entire connected flat surfaces (islands)?
- Edge Select
- Face Select with L key (Correct answer)
- Vertex Select
- Linked Flat Faces select
Correct answer: Face Select with L key
In Face Select mode, pressing L (or Shift+L) selects linked geometry under the cursor, while Select Linked Flat Faces groups connected coplanar faces.
Question 6: What does the 'Bevel' operation (Ctrl+B) do in Blender?
- Smooths vertex normals
- Chamfers edges by creating new geometry along selected edges (Correct answer)
- Extrudes edges outward
- Merges nearby vertices
Correct answer: Chamfers edges by creating new geometry along selected edges
Ctrl+B bevels selected edges by replacing them with angled faces, creating chamfered or rounded edges.
