The '''3D ACIS Modeler''' ('''ACIS''') is a [[geometric modeling kernel]] developed by [[Spatial Corp]]oration (formerly Spatial Technology), part of [[Dassault Systèmes]]. ACIS is used by software developers in industries such as [[computer-aided design]], [[computer-aided manufacturing]], [[computer-aided engineering]], architecture, engineering and construction, [[coordinate-measuring machine]], [[3D animation]], and shipbuilding. ACIS provides software developers and manufacturers the underlying 3D modeling functionality.

ACIS features an [[object-oriented]] C++ architecture with 3D modelling capabilities. ACIS is used to construct applications with hybrid modeling features, since it integrates [[wireframe model]], [[Surface (topology)|surface]], and [[solid modeling]] functionality with both [[List of manifolds|manifold and non-manifold topology]], and a set of geometric operations.
