Geometry Creation Dynamic Geometry Creation Dynamic PlanesPlanes

• For the center section geometry you will use Dynamic Planes• Dynamic Planes are an extremely useful function that allows

easy visual manipulation of planes.• Origins can be created by snapping to entity features. • Coordinate system orientation can easily be changed by

grabbing an axes and rotating it with the mouse.

Geometry Creation - Swept Geometry Creation - Swept SurfaceSurface

You create a Swept Surface by sweeping curves along a path. You define the

surface with two types of curves:• Across curves perform the sweep, defining the surface's cross-

sections.• Along curves define the sweep's path or trajectory

Geometry Creation Geometry Creation Flat Boundary & Fillet SurfacesFlat Boundary & Fillet Surfaces

• Flat boundary surfaces are trimmed NURBS surfaces created within a boundary defined by a closed, flat chain

• With fillet surfaces you can create one or more fillet surfaces, each of which is tangent to two surfaces.
