Sweep Modifier explanation and Some logos modeling in editable spline :-
Use the Sweep modifier to extrude a cross-section along an underlying spline or NURBS curve path.
You can work with a series of pre-made cross-sections such as angles, channels and wide flanges, and can also use your own splines or NURBS curves as custom sections.
This modifier is also very useful for creating structural steel details, molding details, or in any situation where you need to extrude a section along a spline. It is similar to the Loft compound object but is more efficient.
Note: The Sweep modifier is similar to the Extrude modifier in that once the Sweep is applied to a spline, the end result is a 3D mesh object. Both sections and paths can contain multiple splines or multiple NURBS curves.

Creating a Custom Section Shape with the Sweep Modifier
Sweep Modifier Panel
After you apply the Sweep Modifier, its interface appears on the Modifier panel, comprising several rollouts.
Pick Shape Dialog (Sweep Modifier)
The Pick Shape dialog is displayed when you select a custom shape in the scene. This shape can be any of the splines, extended splines or NURBS curves.
Extract Shape Dialog (Sweep Modifier)
The Extract feature allows you to recover custom cross-sections that may have been deleted from the scene. As long as you have a Sweep object in the scene that uses the deleted shape as a custom cross-section, you can use Extract to restore the shape to the scene.
Merge File Dialog (Sweep Modifier)
The Merge File dialog for the Sweep modifier appears when you click the Merge From File button. Merge From File allows you to bring shapes or section profiles from other scene files into the current scene.
1. In this tutorial we are going to look the overview of sweep modifier. Detailed explanation with object will be shown in next part of sweep modifier.
2. In this tutorial we will learn how to use custom shape profile for sweep modifier and create some of the objects using sweep modifier.
Editable Spline :-
Editable Spline provides controls for manipulating an object as a spline object and at three sub-object levels: vertex, segment, and spline.
Create or select a spline > Modify panel > Right-click spline entry in the stack display > Convert To: Editable Spline
Create a line > Modify panel
Create or select a spline > Right-click the spline > Transform (lower-right) quadrant of the quad menu > Convert To: > Convert to Editable Spline
The functions in Editable Spline are the same as those in the Edit Spline modifier. The exception is that when you convert an existing spline shape to an editable spline, the creation parameters are no longer accessible or animatable. However, the spline's interpolation settings (step settings) remain available in the editable spline.
When a spline-editing operation (typically, moving a segment or vertex) causes end vertices to overlap, you can use the Weld command to weld the overlapping vertices together or the Fuse command if you want the two overlapping vertices to occupy the same point in space but remain separate vertices.
Note: Welding coincident vertices is controlled by the End Point Auto-Welding feature.
