Divide a 3D box into 3D box


#1

Hi,
I’m wondering, if there is an easy way to split a 3D object into other 3D objects (with or without a plug-in)?
For instance, suppose that you designed a cube and you want to split it into 4 parts to obtain 4 smaller cubes

Thanks,
Phil

This may help, just guesting this is what you meant. As you can “nest” groups inside of groups and same with components. And combined groups and components, but be aware you can get confused quickly. …Peace…

Whouaw, not only a great idea but it also allows me to keep a backup of the original shape

Thanks a lot,
Phil

Yes, groups and components share a few common characteristics, but components take them a step further. Offer more options or traits is a better word. most importantly is keeping the original part // objects geometry (the edges and faces that compose it) separate. Nothing will stick to it or be joined unless you “open” it up to edit. So the original cube is grouped.Then the individual cubes can be made groups and moved, rotated or interlocked. Opening the original and changing size or modifying it will not affect the other items. Were as components are separate from other geometry but share or reflect ALL edits to one. It is a double edge sword sometimes, unless you make them “Unique”. There is a wealth of info on them AND TAKE THE TIME to research them. They are the ground work over any tool or plug-in. This is taken from the Concepts Guide and REALLY explains them you can bookmark it or go to it. LEARN THEM they are your best friends!!

Groups and components
Groups and components are entities that can hold other entities. Groups are commonly used to combine several entities into a single entity for the purposes of performing a quick operation on the group (such as a copy or move). For example, you might draw a model, group the entities that compose model and move the entire model. The characteristics of groups are:

Quick selection. When you select a Group, all elements within that group are selected as well.
Isolation of geometry. Entities within groups are protected from the rest of the model. Geometry outside of the group does not affect the geometry within the group
Model organization. Groups can be nested within other groups resulting in hierarchical collection of subgroups.
Group material. The group as a whole can be assigned a material of its own, which is separate from the materials painted on individual entities within the group. See the Materials section within this topic for further information.
Drawing Axes. Groups maintain their own internal drawing axes.
Alignment and Hole Cutting. Groups have a special behavior that allows them to properly align themselves and stick to faces on which they are placed (as well as cut holes in those faces).

Components are just a group with special behaviors, namely behaviors allowing them to be inserted in other models. For example, you might create a model of a car that you want to bring into other SketchUp models, such as the model of a house. Any models you create can be a component.

Components have the following characteristics, in addition to the characteristics of groups:

component definition. The component definition is the blueprint that defines the appearance and behavior of all component instances (created when you insert the component in the model). Editing a component instance edits the definition and all instances accordingly. However, some actions, such as scaling an instance, only affects the instance itself.
Improved Performance. Components allow SketchUp to more efficiently use your computer's resources because the information necessary to describe a component is only stored once, in the component definition, and then referenced for every component instance.
Drawing Axes. Components display their own internal drawing axes when you are editing the component.
Alignment and Hole Cutting. You can define alignment and hole cutting behavior when creating components (it is automatically defined for groups).

Note: You can define the characteristics of the component during component creation.

Group and component context
Entities within a group or component are said to exist within the group or component’s scope or context. You can modify a group or component as a whole (affecting all of the entities within the group or component) or edit the group or component’s individual entities (within the group or component’s context). Additionally, you can nest components within other components, groups within components, components within groups and so on. The following image shows a shelf component has been selected (as indicated by the yellow selection color) using the Select tool. This shelf is composed of several subcomponents, such as slats.

The following image shows the shelf component being edited. Notice that it has a dashed bounding box to indicate you are in the component’s context. In this case, a subcomponent, one of the slats in the shelf, has been selected. That slat is within the context of the shelf. Also notice that the component’s axes are displayed in the lower left-hand corner.

Finally, the following image shows the slate component being edited. Notice now that there is a dashed bounding box around the component, and around the slat being edited. The entities, such as the lines and face, that compose that individual slat are said to be in the context of the slat.

Component collections
Component collections have been created and included with SketchUp to allow you to easily add detail to your models. These components range from standard architectural components (doors, windows, and so on) to people, cars, trees, and geometric shapes. You can also create your own collections of components from pre-existing components or components you create yourself.

Note: Individual components and collections of components are available on the 3D Warehouse.

Component axes
Components have their own axes which, by default, are aligned to the global axes in the drawing area. These axes can be moved affecting component placement in the model.

Cutting and gluing behavior
Components, such as doors and windows, can be designed such that they can be placed on specifically-oriented surfaces such as vertical wall surfaces. This behavior is referred to as the gluing behavior of a component.

Additionally, components can be designed to automatically cut holes in surfaces, such as in the case of a window component being able to cut a hole in a wall. This behavior is referred to as the cutting behavior of a component.

Layers, groups and components
Layers are a mechanism for controlling the visibility of entities within a model. Entities can be assigned to different layers in a model and those layers, and their contents, can be displayed independently. Groups and Components are used to isolate geometry as sub-models within an overall model, such as a component of a chair within a model of a room.

There are many simple ways to cut shapes. A bit more information would help.
For instance it would be faster to draw a smaller cube and array it than split a cube into pieces.
Whereas splitting an organic model into four sections would be done by a simple intersect faces.
