[NX8-HELP] MESH SURFACE 1 Mesh Surface drive24ward (meslab.org/mes) Mesh Surface View a topic Ruled surface Through Curves Through Curve Mesh Section Surface N-Sided Surface overview 1. Ruled surface Use the Ruled command to create a body between two sections, where the ruled shape is a linear transition between the sections. A section can consist of single or multiple objects, and each object can be a curve, a solid edge, or a solid face. Input Curves and output Ruled surface Ruled surfaces can be used to create surfaces that can be unfolded onto a plane without stretching or tearing. These surfaces are used in the shipbuilding and piping industry to manufacture objects from sheet metal. Where do I find it? Application Modeling Toolbar Surface→Mesh Surface Drop-down→Ruled Menu Insert→Mesh Surface→Ruled 1.1. Create a ruled surface using points This example shows how to create a surface between circular and rectangular sections. [NX8-HELP] MESH SURFACE 2 Mesh Surface drive24ward (meslab.org/mes) 1. Choose Insert→Mesh Surface→Ruled. 2. Select the first section. For this example, do the following a. On the Selection bar, set the Curve Rule to Connected Curves. b. In the Ruled dialog box, in the Section String 1 group, click Select Curve and select the first section in the graphics window. 3. Select the second section. For this example, do the following: a. On the Selection bar, set the Curve Rule to Connected Curves. b. In the Section String 2 group, click Select Curve and select the second section string in the graphics window. 4. In the Alignment group, from the Alignment list, select a method. For this example, from the Alignment list, By Points is selected. [NX8-HELP] MESH SURFACE 3 Mesh Surface drive24ward (meslab.org/mes) Default points appear on the selected sections. You can realign the points or specify new points. 5. Click OK or Apply to create the Ruled surface. 1.2. Ruled dialog box Section String 1 and Section String 2 Select Curve or Point Lets you select the section string. Specify Origin Curve Lets you specify the origin curve for the selected section string. Alignment Alignment Controls the shape of the feature by defining how NX spaces the isoparametric curves of the new surface along the sections. Isoparametric curves are generated along the U and V parameters on a face. For more information see **Unsatisfied xref title**. When the Preserve Shape check box is selected, you can use only the Parameter and By [NX8-HELP] MESH SURFACE 4 Mesh Surface drive24ward (meslab.org/mes) Points alignment methods.  Parameter — Spaces the isoparametric curve connection points at equal parameter intervals along the sections. NX uses the entire length of each curve.  By Points — Aligns points between sections of different shapes. NX places alignment points and their alignment lines along the sections. In this example, a Ruled surface is created between sections of different shapes, a circle and a rectangle, using points to align the sections. Specify Point option is available to let you realign the points or add new ones. You can also click Reset to restore the default alignment points. When the Preserve Shape check box is cleared, the following additional methods are also available.  Arc Length — Spaces isoparametric curve connection points at equal arc length intervals along the defining sections. NX uses the entire length of each curve.  Distance — Spaces points along each section at equal distances in a specified direction. This results in isoparametric curves that all lie in planes perpendicular to the specified direction vector. Specify Vector options are available to let you specify the direction in which the isoparametric curves must be spaced.  Angle — Spaces the points along each curve at equal angles around a specified axis line. This results in isoparametric curves which all lie in planes containing the axis line. Specify Vector and Specify Point options are available in the Axis group to let you specify the direction and location of the axis.  Spine Curve — Places the points at the intersections of the selected sections and planes perpendicular to a selected spine curve. The extent of the resulting body is based on the limits of this spine curve. Select Spine Curve option is available to let you select the spine curve. Spine curves that are all, or in part, perpendicular to the defining sections are [NX8-HELP] MESH SURFACE 5 Mesh Surface drive24ward (meslab.org/mes) invalid, because the intersection between the section planes and the defining curves is nonexistent, or poorly defined. For more information on alignment options, see Alignment methods. Settings Body Type Lets you specify either a sheet body or a solid body for the ruled feature.  Solid  Sheet To get a solid body, the section strings must form closed loops. Preserve Shape Preserves sharp corners by forcing a tolerance value of 0.0, overriding the default of approximating the output surface. When you clear this check box, the G0 (Position) value is used and any sharp corners in the section strings are smoothened, but with a small radius of curvature. Note This options is available for all alignment methods, but you can use this option only when Alignment is set to Parameter or By Points. G0 (Position) Lets you specify a maximum distance between the input geometry and the resulting body. 2. Through Curves Use the Through Curves command to create a body through multiple sections where the shape changes to pass through each section. A section can consist of a single object or multiple objects, and each object can be any combination of curves, and solid edges, or a solid face. You can do the following:  Use multiple sections to create a sheet body or solid body.  Control the shape of the surface by aligning it to the sections in a variety of ways.  Constrain the new surface to be G0, G1, or G2 continuous with tangent surfaces.  Specify single or multiple output patches.  Make the new surface normal to the end sections. The Through Curves command is similar to the Ruled command. With Through Curves, you can use more than two sections and you can specify tangency or curvature constraints at the start and end sections.

Create a through curves surface This example shows how to create a basic Through Curves surface through six sections. Each section consists of two tangent curves. 1. On the Surface toolbar, click Through Curves or choose Insert→Mesh Surface→Through Curves. 2. Set the Selection Intent rule. For this example, on the Selection bar, from the Curve Rule list, Tangent Curves is selected. 3. Select a curve and click the middle mouse button to complete the selection of the first section. For this example, the first curve at the upper end is selected. Since you selected Tangent Curves as your selection rule, two tangent curves are added to your model and displayed as Section 1 in the List box. 4. Select additional curves and add as a new section. For this example, each set of tangent curves is selected and added as a new section.

Click OK or Apply to create the Through Curves surface. The surface is created using the default options in the Alignment and Output Surface Options groups. For this example, the default Parameter alignment method is used. 6. Double-click the Through Curves surface to edit it. The Through Curves dialog box opens. 7.
