Loft and Loft Cut

From the Features section of the action bar, click Loft .

Select the feature options in the Loft dialog box.

Option	Description
	Add. Combines the geometry created by the current feature with solid geometry it contacts or intersects.
	Cut. Subtracts the geometry created by the current feature with the solid geometry it intersects. Note: You cannot apply cut feature to a sheet metal geometry.
	New. Creates a body from the geometry created by the current feature but does not combine it with the geometry it contacts or intersects.
	Solid. Creates a solid feature.
	Thin. Creates a feature with a constant wall thickness. To set the wall thickness, drag the handle, or enter a value in the callout in the work area. Enter a Thickness value to set the wall thickness of the loft. Click Thin Midplane to set the wall thickness to be equal in both directions from the loft midplane.
	Surface. Creates a feature with a zero-thickness wall.

Under Sections, select sections to loft between. Select the profiles that define the loft such as model edges or faces and sketch entities or contours.

Note: You cannot apply loft feature to a sheet metal geometry.

Select the Profile Propagation.

Option	Description
Chain Propagation	The profile is defined by the selection and all edges or sketch entities that are connected to it in series. It does not care if the continuity is point, tangent, or curvature continuous.
Tangent Propagation	The profile is defined by the selection of all edges or sketch entities that are connected tangentially or curvature continuous to the initial selection. Propagation continues until a closed profile is made or a nontangential entity is encountered.
None	The profile is defined only by the selection. No connected entities are considered.

Under Coupling, from the Coupling Types list, select one of the following.

Option	Description
Vertices	Connects the profiles starting from the closing point and proceeding sequentially vertex by vertex in the direction of the orange arrow.
Ratio	Connects the profiles starting from the closing point and proceeding sequentially segment by segment based on the ratio of perimeters for each profile in the direction of the orange arrow.
Tangent Discontinuity	Connects the profiles starting from the closing point and proceeding sequentially vertex by vertex in the direction of the orange arrow. Vertices that connect two tangent continuous entities are not coupled between profiles.
Curvature Discontinuity	Connects the profiles starting from the closing point and proceeding sequentially vertex by vertex in the direction of the orange arrow. Vertices that connect two curvature continuous entities are not coupled between profiles.

Note: If the profiles you are attempting to Loft do not have an equal number of vertices, you can add vertices by splitting lines in the profile to create an equal number of vertices.

Optional: Click Add Coupling Curves to specify a point on a loft profile that allows you to connect the profiles having unequal number of vertices during loft creation.

Note: You can also use Ratio coupling type that automatically creates a loft from the profiles with unequal number of vertices.

Under Control Curves, select one of the following.
- Spine Curve to specify a curve for all the profiles of the loft to follow. You can specify only one spine curve.
- Guide Curve to specify a curve that passes through a vertex in each profile. You can specify multiple guide curves.
Select Tangent Propagation check box to enable selections of edges or sketch entities that are connected tangentially or curvature continuous to the initial selection. Propagation continuous until a closed path is made or a nontangential entity is encountered.

Note: This option becomes available when you select Spine Curve.

From the Guide Propagation list, select one of the following.

Option	Description
Chain Propagation	The profile is defined by the selection and all edges or sketch entities that are connected to it in series. It does not care if the continuity is point, tangent, or curvature continuous.
Tangent Propagation	The profile is defined by the selection of all edges or sketch entities that are connected tangentially or curvature continuous to the initial selection. Propagation continues until a closed profile is made or a nontangential entity is encountered.
None	The profile is defined only by the selection. No connected entities are considered.

Note: This option becomes available when you select Guide Curve.

Select Close loft check box to close the Loft functionality by connecting the first and last sections.

Note: This option becomes available when you select Spine Curve and/or Guide Curve.
Optional: Under Merge, set Auto Merge to automatically merge the loft with other features.
1. Clear Auto Merge and manually select the bodies to merge with the loft.
