To create a surface blend, activate the N-Blend tool and click on the two. Click on either control point and move it along the edge of the input surface to move the seam of the blend. This tool creates a geometrically continuous blend between two NURBS surfaces. When on, control points will appear at the top and bottom of the seam of the blend surface. It does so using Gaussian noise reduction techniques.Īdjust Seam: This option becomes available when creating blends between two surfaces that are closed in one direction. formZ Nurbs Surfaces formz3D 3.84K subscribers Subscribe 41 Share Save 15K views 10 years ago Discover formZ - tutorials Create, edit and sculpt complex forms using the nurbs tools in. The Smooth button, when used, repairs any bumps or other "wrinkles" that may have been left on a surface. Align Boundary Edges applies only when an edge to be blended is a trimmed edge and aligns corresponding edges. You may adjust the magnitude of the tangents at all isolines at once by moving the T1 and T2 Magnitude sliders on the tool options palette.įlip Edge Orientation will adjust the direction of an edge if the orientations of the blended ends do not match and the blend is twisted. The two arrows are adjusted independently, unless Synchronize Arrows is on, when they move and are adjusted simultaneously. To adjust the tangent magnitudes at a different isoline, click on the control point at the base of the arrow and slide the control along the connecting edge to the desired position. Adjusting the magnitude arrows will increase or decrease the magnitude of the tangent of the blend surface at the corresponding isoline, changing the shape of the blend. When the surface blend is created, two direction arrows corresponding to U or V isoline tangents will appear at the corner endpoints of the input surfaces. The options G0 through G4 are as described for the Curve Blend tool.
The desired geometric Continuity of the blend can be selected for each input surface from the choices in the drop down menus in the tool options palette. To create a surface blend, activate the N-Blend tool and click on the two surface edges to be blended. This tool creates a geometrically continuous blend between two NURBS surfaces.
