BUILD SOLID CAD MODELS FROM OPTIMIZED GEOMETRIC ENTITIES

The solid modeling philosophy of PolyWorks Modeler consists in optimizing the extraction of geometric entities on digitized polygonal models, and then transferring these entities to your corporate feature-based solid CAD modeler to guarantee the creation of parametric, associative, and fully editable solid models.

A fundamental building block in a solid modeling workflow is the parametric 2D sketch. 2D sketches consist in planar entities, such as arcs, lines, circles, and splines, defined on a plane embedded in 3D space. In solid-modeling software, sketches are used to create solid base features by performing Extrude, Revolve, Sweep, and Loft operations. Sketches are created by:

• Defining a sketch plane
• Computing a sketch outline by slicing cross-sections of the digitized model or extracting its silhouette edge
• Anchoring and fitting sketch entities and dimensions, guided by the sketch outline

 The parametric sketches are then transferred to the solid CAD modeler by using add-ins (for CATIA, NX, Creo, SolidWorks, and Inventor) or a neutral format (IGES). You can then combine the sketches and fitted NURBS surfaces, use the dimensions from fitted prismatic geometry, and design the solid model you want—all done directly in the professional CAD solution that you’re most familiar with.

HOW TO MEASURE

Solid modeling is a consistent set of principles for mathematical and computer modeling of three-dimensional solids. Together, the principles of geometric and solid modeling form the foundation of computer-aided design and in general support the creation, exchange, visualization, animation, interrogation, and annotation of digital models of physical objects
