Create loft to point

For an open loft, select a point for the beginning or end section, and then apply conditions to the point section.

To create a loft with a pointed or cone-shaped tip, apply the Sharp point condition. To create a loft with a rounded, dome-shaped tip, apply a tangent condition. To control the rounded tip, apply a tangent to plane condition and select a tangency plane.

Lofts between two-point sections must include an interior section to define the section shape.

1. On the ribbon, click 3D Model tab Create panel Loft .
2. On the Curves tab, specify the sections to loft. Click under Sections, and then click the sections in the sequence you want the shapes to blend.
   • Point sections must be at the beginning or end of the loft.
   • If you select multiple sections on any plane, they must intersect.
   • If more than one loop is in a sketch, first select the sketch, and then select the curve or loop.
3. Optionally, specify whether to create a loft with rails, or a centerline. Use the context menu and switch between Sections, Rails, and Centerlines, or change the selection type in the dialog box. Select a single 2D or 3D curve for centerline, or one or more curves for guide rails. Sections must intersect rails, but need not intersect a centerline.
   Note: When specifying a centerline with a point, the centerline must pass through the point section and near the middle of the neighboring section.
4. If the part contains more than one solid body, to choose the participating body, click the Solids selector.
5. In Output, select solid, or surface.
6. To join the beginning and ending sections of the loft, click Closed Loop.
7. To merge loft faces without a seam, click Merge Tangent Faces.
8. Under Operation, click Join, Cut, Intersect or new solid .

1. On the Conditions tab, specify the boundary condition for the listed sections and rails.

   For point sections:

   • Sharp Point Creates a pointed or cone-shaped tip.
   • Tangent Creates a rounded, dome-shaped tip. Then set the weight of the condition.
   • Tangent to Plane Select, specify a work plane or planar face, and then set the weight of the condition.

   For other sections and rails:

   • Free Condition Applies no boundary condition.
   • Tangent Condition Creates a loft tangent to the adjacent faces. Then set the weight of the condition.
   • Direction Condition Specifies that the angle is relative to the section or rail plane. Set the angle and the weight of the condition.
   • Smooth (G2) Condition Creates a loft curvature continuous to the adjacent faces.
   Note: The sketch or edge that you select highlights in the graphic.
2. On the Transition tab, Automatic Mapping is selected by default. If appropriate to modify automatically created point sets, or to add or delete points, clear the checkbox.
   • To modify, add, or delete, click the point set row.
   • A default calculated map point is created for each section sketch. To specify a unitless value (zero represents one end of the line; one represents the other end. Decimal values represent positions between ends), click position.
   Note: The point set or map point that you select highlights in the graphics area.
3. To create the loft, click OK.
