<p>The <b>3D ACIS Modeler</b> (ACIS) is Spatial's prominent 3D modeling engine used by hundreds of software developers in more than 14 industries worldwide, including CAD/CAM/CAE, AEC, animation, and shipbuilding. ACIS provides some of the world's most recognized software developers and manufacturers with the underlying 3D modeling functionality necessary for creating innovative, high-performance applications.</p><blockquote class="templatequote"><div><p><i><b>Important:</b> One must not judge a work of art by it's defects. </i>Ancient Chinese Proverb<i>.</i></p></div></blockquote><table id="toc" class="toc" summary="Contents"><tr><td><div id="toctitle"><h2>Contents</h2></div><ul><li class="toclevel-1"><a href="#Functionality"><span class="tocnumber">1</span> <span class="toctext">Functionality</span></a></li><li class="toclevel-1"><a href="#ACIS_Core_Functionality"><span class="tocnumber">2</span> <span class="toctext">ACIS Core Functionality</span></a><ul><li class="toclevel-2"><a href="#3D_Modeling"><span class="tocnumber">2.1</span> <span class="toctext">3D Modeling</span></a></li><li class="toclevel-2"><a href="#3D_Model_Management"><span class="tocnumber">2.2</span> <span class="toctext">3D Model Management</span></a></li><li class="toclevel-2"><a href="#3D_Model_Visualization"><span class="tocnumber">2.3</span> <span class="toctext">3D Model Visualization</span></a></li></ul></li></ul></td></tr></table><script type="text/javascript"> if (window.showTocToggle) { var tocShowText = "show"; var tocHideText = "hide"; showTocToggle(); } </script><a name="Functionality"></a><h2> <span class="mw-headline"> Functionality </span></h2><div class="thumb tright"><div class="thumbinner" style="width:182px;"><a href="/r18/index.php/Image:SPApushplane.gif" title="Image:SPApushplane.gif">Image:SPApushplane.gif</a> <div class="thumbcaption"><center>Modeling with ACIS.<br/> <i>Model courtesy of Spatial customer IronCAD LLC.</i></center></div></div></div><p>ACIS features an open, object-oriented C++ <a href="/r18/index.php/Architecture" title="Architecture">architecture</a> that enables robust, 3D modeling capabilities. ACIS is ideal for constructing applications with hybrid modeling features, since it integrates wireframe, <a href="/r18/index.php?title=Surface&action=edit" class="new" title="Surface">surface</a>, and solid modeling functionality with both manifold and non-manifold <a href="/r18/index.php?title=Topology&action=edit" class="new" title="Topology">topology</a>, and a rich set of geometric operations. With ACIS, you get a sound base of 3D modeling functionality, plus the flexibility to meet individual application requirements.</p><p>To simplify development with ACIS, Spatial made its licensing plan accessible to software developers on a budget. Our business model allows you to develop applications using ACIS without up-front costs for the first year, or until your products ship. As a result, our revenue is directly tied to your time-to-market and success.</p><a name="ACIS_Core_Functionality"></a><h2> <span class="mw-headline"> ACIS Core Functionality </span></h2><a name="3D_Modeling"></a><h3> <span class="mw-headline"> 3D Modeling </span></h3><ul><li> Extrude/revolve/sweep sets of 2D curves into complex surfaces or solids.</li><li> Fillet and chamfer between faces and along edges in surface and solid models.</li><li> Fit surfaces to a closed network of curves.</li><li> Generate <a href="/r18/index.php?title=Patterns&action=edit" class="new" title="Patterns">patterns</a> of repetitive shapes.</li><li> Hollow solids and thicken surfaces.</li><li> Interactively bend, twist, stretch, and warp combinations of curves, surfaces, and solids.</li><li> Intersect/subtract/unite any combination of curves, surfaces, and solids.</li><li> Loft surfaces to fit a set of profile curves.</li><li> Taper/offset/move surfaces in a model.</li></ul><a name="3D_Model_Management"></a><h3> <span class="mw-headline"> 3D Model Management </span></h3><ul><li> Attach user-defined data to any level of a model.</li><li> Track <a href="/r18/index.php?title=Geometry&action=edit" class="new" title="Geometry">geometry</a> and topology changes.</li><li> Calculate mass and volume.</li><li> Model sub-regions of a solid using cellular topology.</li><li> Unlimited undo/redo with independent history streams.</li></ul><a name="3D_Model_Visualization"></a><h3> <span class="mw-headline"> 3D Model Visualization </span></h3><ul><li> Tessellate surface geometry into polygonal mesh representation.</li><li> Create advanced surfacing capabilities with the optional Deformable Modeling component.</li><li> Generate precise 2D projections with hidden line removal using optional PHL V5 component.</li><li> Develop graphical applications easily using Tech Soft America's <a href="/r18/index.php/HOOPS" title="HOOPS">HOOPS</a> 3d Application Framework, available from Spatial and integrated with ACIS.</li></ul>⌨️ 快捷键说明
