1 3D ACIS Modeler

2 ACIS 2005 ACIS is the commercial modeler product of Spatial and Dassault Systemes Development continues to expand Quality and performance increases with each release Growing business, as indicated by continued interest and development

3 3D Modeling Goals - Strategic Commercial Partner Growth Satisfy the specific needs of current partners necessary to support their growth Core Technology Continuous improvement of the ACIS core modeling structures to maximize Modeler robustness, performance, and extensibility Competitive Strength Identify and address competitive deficiencies, and build on existing competitive advantages (functionality and performance) Increase Product Portfolio Seek out and deliver additional technologies needed by our partners

4 R15 Highlights A brief review of major improvements made to ACIS in R15

5 Local Operations: Adaptive Offsetting New ability to offset surfaces with: Local areas of high curvature Small Non-G1 discontinuities Geometric singularities Illegal parameterization Progenitor Surface with High Curvature Cusp Progenitor after smoothing of High Curvature Progenitor Surface with a geometric singularity Progenitor after flattening to remove geometric singularity Progenitor Surface with an illegal parameterization Progenitor Surface after parameterization change du dv

6 Skinning / Lofting with Lateral Edge Tangency Control Improved shape produced by Skinning and Lofting when the input is a set of tangent curves. Input Green edges are tangent at red vertex Old Result Near-tangent surface intersection New Result Tangent surface intersection

7 Blending Improvement New ability to process Edge Blends when Sidecap faces intersect Miters

8 Remove Faces Performance Improvement Eliminated old n 2 algorithm, no more ‘forever’ solutions which seem like a hang Removed some limitations around free edges More details in the LOPS presentation…

9 Other Improvements in R15 Performance gain in entity box calculations (spline surfaces) Improved performance and robustness in mass properties calculations HA/Bridge enhanced to allow silhouette picking Tolerant Modeling improvement – smoother, tighter TCOEDGE generation algorithm New platform support for Microsoft Windows XP Professional x64 Edition (certified on AMD® Opteron ®)

14 Pervasive SAT Format Open file format Provides data exchange between ACIS applications without data translation Backwards compatible ACIS is used on more desktops than any other modeler HOOPS/ACIS 3D Part Viewer 3D image of paint mixer. Provided courtesy of Fluent Inc.

15 Quality Philosophy Underlying philosophy for all Spatial software subsystems and services Quality-driven, continuous improvement approach 3D image of vehicle tire, modeled in ACIS-enabled Gambit, utilized ACIS surface functionality. Provided courtesy of Fluent Inc.

16 3D ACIS PHL V5 Accurate 2D representations of 3D models ideal for technical illustration, manufacturing and architecture Based on same industrial-strength Hidden Line Removal (HLR) technology used in CATIA V5 Twice as fast as legacy PHL Husk, with greater accuracy Direct modeler interface for ACIS-enabled applications Windows and UNIX support

17 Hidden line removal display. Dashed hidden line display. Edge and Silhouette Classification Analyzes surface and solid models to determine which lines and line styles to draw Visible Hidden Occluded Wireframe view of 3D ACIS model.

18 Exact or Polyline Edge B-Representation Curve representation Provides access to actual curve data or provides a polyline approximation for less detail Thickening/thinning Displays exterior edges as "thick" and interior lines as "thin“ Smoothing Eliminates irrelevant contour lines Example of thickening/thinning Thickened Thinned

19 Adjustable Levels of Accuracy PHL V5 automatically calibrates hidden line calculation accuracy based on model extents Level of accuracy can be manipulated by users needing higher level of control

20 3D Deformable Modeling Interactive curve and surface manipulation tool Results in precision curves and fair surfaces Available for ACIS and non-ACIS-enabled applications 3D image of prototype car created in ACIS-enabled Vertex Mechanical Engineering.

21 Intuitive creation of free-form NURBS Constraints, forces and pressures Supports default shapes Supports hierarchical patches Allow for control of position, tangent, and continuity between surfaces 3D Deformable Modeling 3D models of a joystick illustrate the use of pressures and loads to locally shape the smooth handle (image 1.) with molded finger-grips (image 2.) 1.2.
