Contents László Horváth ÓU-JNFI-IIES uni-obuda.hu/lhorvath/ Multi-Sections Surface Lecture Laboratory Curves for surface definition in reference planes Creating the complex solid shape as it is illustrated in surface definitions of the lecture 8. Integrated laboratory task VE : Blend surface Swept surface Joining surfaces Tabulated surface Fillet surface on solid Limiting solid by surface Solid between boundary and its offset Angle of a surface (draft) in boundary

3
Curves for surface definition in reference planes László Horváth ÓU-IAM

4
Multi-Sections Surface László Horváth ÓU-IAM Sweeping one or more section curves along an automatically computed or user-defined spine.

5
Swept surface Generator Path Spine joint Profiles Boundary curves Basic parameters Spine Rotation and scale along path László Horváth ÓU-IAM Sweeping a generator curve through planes normal to a spine curve.

6
Swept surface László Horváth ÓU-IAM

7
Blend surface László Horváth ÓU-IAM Surface between two curves. Constraints: continuity, etc.

8
Tabulated surface László Horváth ÓU-IAM Moving a contour along a vector. Swept area is the surface.

9
Tabulated surface László Horváth ÓU-IAM

10
Joining surfaces László Horváth ÓU-IAM An operation to assemble adjacent surfaces into a single surface.
