Final answer:
To select a line on an object, Edge Select mode is used. Materials are preferred to change color and sheen, while the Material panel hosts the Color picker to adjust the texture's color. You can apply colors to Blender objects such as a cylinder.
Step-by-step explanation:
To select a line on an object in 3D modeling software, you would use the Edge Select mode. This mode allows you to select the edges of polygons that make up your 3D model.
When deciding between adding a material or a texture to an object, one should opt for a material if they want to change an object's color and make it shiny. Materials can affect the entire surface of an object, whereas textures are typically used for more detailed surface imagery, like zebra stripes.
If you need to change the color of a texture on an object, you should use the Color picker in the Material panel. This panel provides various options to adjust the color and appearance of the applied texture.
Creating a parent/child relationship between two objects is useful when you want two objects to move or transform together while remaining as separate entities. This relationship allows for hierarchical transformations, which means if you move the parent object, the child object will follow accordingly while retaining its own transformations.
In Blender, you can apply colors to objects like a cylinder. Colors can be applied to any mesh object through materials and textures in Blender's material editor.
