Selections and Filters
Fillet, chamfer, shell, and color all need you to tell them which edges or faces to target. FluidCAD gives you two ways to do that: direct selection from operations, and filter-based selection.
Transforms
Transforms move, rotate, and mirror existing geometry in 3D space.
Chained Transforms
Primitive shapes — cylinder() and sphere() — expose chainable .translate(), .rotate(), .mirror(), and .transform() methods so you can place them in a single expression.
Copying
copy() duplicates the entire shape in linear or circular arrangements. The original solid is cloned as-is — FluidCAD doesn't re-run any modeling operations, it just places copies of the finished shape at new positions.
Repeating
repeat() re-applies a modeling feature at multiple positions. Unlike copy(), which duplicates the finished shape, repeat() re-runs the operation — so the feature interacts with the solid at each new location just as if you had written it there by hand.
Booleans and Fusion
FluidCAD automatically merges (fuses) solids that touch. This guide explains how auto-fusion works and how to use explicit boolean operations when you need more control.

Reusable Objects
Most features in FluidCAD consume their inputs. When you extrude() a sketch, the sketch geometry is removed from the scene so it can't accidentally be picked up by the next feature. The same applies to selections used by shell(), cut(), sweep(), and so on.
