Having the right tools for the job makes problem solving both fun and efficient. The Kubotek hybrid modeling technology fully supports hybrid power by mixing several techniques at any time when editing a model. For example, when an area of a solid requires dramatic shape change, the faces in that area can be replaced quickly with new faces created as surfaces. When the shape of an imported surface model needs to be removed from where it intersects with a complex solid, Kubotek technology can quickly and simply trim the solid with the surface. These functions are kept simple because no attempt is made to preserve a history of the operation. That's because preserving history would require the trimming entities be turned into a constrained sketch or other linked data form.

Efficient hybrid modeling often requires pulling simple pieces of a lower form of geometry off existing models. As an example, lifting wireframe edges off a solid to use as guide curves when creating a surface. Kubotek provides simple tools to extract any type of data needed from existing model geometry without affecting the original model. Examples of additional types of available data include intersection curves, silhouette curves, normal vectors, polygon meshes, bounding boxes, and flat patterns. When higher form entities are needed in lower forms they can be quickly converted, such as text turned into polylines or polylines turned into lines.

Hybrid modeling frequently involves breaking solids into surface models by stripping off faces (unstitch) or combining a set of surfaces (stitch) that form watertight 3D solids. Kubotek technology provides the best support in the industry for forming solids out of hundreds of adjacent surface entities. It is this advantage that makes true hybrid modeling possible. The hybrid approach opens up the freedom and speed of surface modeling without loosing the assessment and modeling advantages of solids.

When using imported data, users may find problems such as gaps in the model, missing faces, etc. When users want to reuse imported data to create a variation on a model, the imported data may come in as a static object (no history). Using the hybrid approach gives users the power and flexibility to work with either solids or surfaces. The user can fix gaps in the model using surfaces and then stitch the model back into one solid. For increased productivity, users can break static solids into surfaces, delete what they don't need, rebuild a new area and stitch the model back into one solid.

Slice and Extend
Kubotek hybrid modeling technology allows solids and surfaces to be quickly trimmed or split with solids, surfaces, planes, or projected wireframe entities. Faces of solids can be extended to meet solids, faces or surfaces similar to the way curves can be extended to meet other curves.

Usage of the Face Replace function

Kubotek hybrid technology allows quick addition of edges to a solid or surface. By projecting existing wireframe entities or drawing splines on the face, new faces can be formed. This technique can also be used to solve modeling challenges such as splitting a part for a mold or as contact patches for FEA analysis.
