+# loft
+
+When having uniform cross sections, you can use [sweep](https://openhome.cc/eGossip/OpenSCAD/lib2x-sweep.html) to create a module. The `loft` here is best when you have a body with multiple crosssections with different geometries. 
+
+**Since:** 2.3
+
+## Parameters
+
+- `sections` : A list of cross-sections, The points must be count-clockwise indexes.
+- `slices` : Defines the number of intermediate points between two sections. Default to 1.
+
+## Examples
+
+	use <shape_starburst.scad>;
+	use <shape_circle.scad>;
+	use <ptf/ptf_rotate.scad>;
+	use <loft.scad>;
+		
+	sects = [
+		for(i = 10; i >= 4; i = i - 1)
+		[
+			for(p = shape_starburst(15, 12, i % 2 == 1 ? i : i - 1)) ptf_rotate([p[0], p[1], 5 * (i - 4)], i * 10)
+		]
+	];
+	loft(sects, slices = 3);
+
+	translate([30, 0, 0])
+	difference() {
+		loft(
+			[
+				[for(p = shape_circle(10, $fn = 3)) [p[0], p[1], 15]],
+				[for(p = shape_circle(15, $fn = 24)) [p[0], p[1], 0]]        
+			],
+			slices = 4
+		);
+
+		loft(
+			[
+				[for(p = shape_circle(8, $fn = 3)) [p[0], p[1], 15.1]],
+				[for(p = shape_circle(13, $fn = 24)) [p[0], p[1], -0.1]]        
+			],
+			slices = 4
+		);    
+	}
