Form operations
Build, combine, and subtract 3D forms while preserving their connections, volume, perspective, and solidity.
What it is
Form operations uses basic boxes, cylinders, and spheres to construct objects. You attach, overlap, wrap, or cut forms while keeping them solid and three-dimensional.
You may draw a handle entering a mug wall, a joint nesting into a limb, or an organic form flowing over an underlying volume. Each part needs visible connection, overlap, and thickness.
You also consider how parts meet, where they pivot, and what a cross-section would show. Objects can be built as connected stacks, chains, and interlocking forms while their perspective and volume remain consistent.
Why it matters
Form operations helps parts read as connected volumes with physical structure. Weak control can make attachments appear pasted on, joints disconnected, or organic forms appear flat and unsupported.
You can check it when
- ✓Construct a simple object from several interlocking forms, such as a boxy torso with cylindrical arms and hips. The parts remain connected as one solid mass.
- ✓Add a form to a basic volume or cut one away, such as attaching a box to a cylinder or removing a bevel from a cube. Its perspective and solidity remain consistent.
- ✓Wrap organic forms, such as muscles, cables, branches, or folds, around underlying volumes. They connect to the forms beneath them.
- ✓Rotate a constructed object through several views. Its parts continue to connect and overlap consistently.
