Add & Delete in Blender #

Adding and deleting objects or components are fundamental operations in Blender that allow you to create and modify your scene. This guide will explore various methods of adding and deleting objects and components in Blender.

1. Add Objects #

To add objects to your scene, follow these steps:

1.1 Object Mode #

1. Make sure you are in Object Mode.
2. Press Shift + A to open the ‘Add’ menu or click the ‘Add’ button in the top-left corner of the 3D viewport.
3. From the menu, choose the desired object type, such as ‘Mesh’, ‘Curve’, ‘Text’, ‘Light’, or ‘Camera’.
4. Select the specific object you want to add, and it will appear at the 3D cursor’s location in the scene.

1.2 Edit Mode #

1. Make sure you are in Edit Mode.
2. Press Shift + A or use the ‘Add’ button in the top-left corner of the 3D viewport.
3. Choose the desired mesh object to add, and it will be added to the scene as part of the active object. Note that only mesh objects can be added in Edit Mode.

2. Delete Objects #

To delete objects from your scene, follow these steps:

2.1 Object Mode #

1. Make sure you are in Object Mode.
2. Select the object(s) you want to delete.
3. Press X or Delete key and confirm the deletion by clicking ‘Delete’ in the popup menu.

2.2 Edit Mode #

1. Make sure you are in Edit Mode.
2. Select the component(s) (vertex, edge, or face) you want to delete.
3. Press X or Delete key, and a context-sensitive menu will appear with deletion options.
4. Choose the desired deletion method, such as ‘Vertices’, ‘Edges’, ‘Faces’, or ‘Dissolve’.

3. Duplicate Objects and Components #

Duplicating objects or components is a useful way to create copies or variations without starting from scratch.

3.1 Object Mode #

1. Make sure you are in Object Mode.
2. Select the object(s) you want to duplicate.
3. Press Shift + D to create a duplicate of the selected object(s), which will remain attached to your cursor. Click to place the duplicate or right-click to cancel the operation.

3.2 Edit Mode #

1. Make sure you are in Edit Mode.
2. Select the component(s) (vertex, edge, or face) you want to duplicate.
3. Press Shift + D to create a duplicate of the selected component(s), which will remain attached to your cursor. Click to place the duplicate or right-click to cancel the operation.

Tips #

1. To add custom objects to the ‘Add’ menu, create a new object and save it as a Blender file. Then, in your project, go to File > Link/Append to link or append the object from the external file.
2. When duplicating objects, you can immediately press X, Y, or Z to constrain the duplicate’s movement to a specific axis.
3. Use the ‘Array Modifier’ or ‘Mirror Modifier’ to create a series of duplicate objects or components with precise control over their placement and spacing.
4. If you want to create a linked duplicate that shares the same mesh data, use Alt + D instead of Shift + D. Changes made to the original mesh will be reflected in the linked duplicate as well. Keep in mind that linked duplicates share mesh data but can have separate materials, modifiers, and transformations.
5. To duplicate a part of a mesh and separate it into a new object in Edit Mode, select the desired components, press Shift + D, place the duplicate, then press P and choose ‘Selection’ from the ‘Separate’ menu. The duplicated components will now be a separate object in the scene.
6. When deleting components in Edit Mode, be cautious of the ‘Dissolve’ option, as it can merge adjacent components and change the topology of the mesh. Use ‘Dissolve Vertices’, ‘Dissolve Edges’, or ‘Dissolve Faces’ to selectively dissolve specific components while preserving the overall mesh structure.
7. To merge objects, select the objects you want to merge in Object Mode, press Ctrl + J and the objects will be combined into a single mesh. To merge components in Edit Mode, select the components, press M, and choose a merging method from the context menu, such as ‘At Center’, ‘At Cursor’, or ‘By Distance’.
8. To split objects or separate components into a new object, select the components in Edit Mode, press P, and choose the desired separation method from the ‘Separate’ menu, such as ‘Selection’, ‘By Material’, or ‘By Loose Parts’.
9. To quickly add an object aligned to the surface of another object, enable the ‘Align to Transform Orientation’ option in the ‘Add’ menu or by pressing Alt + A before adding the object. This will align the new object’s orientation to the surface normal of the object under the 3D cursor.
