[GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md) → [S](Help%20System/GSTARCAD/2027/Commands/S/(S).md)
## Function Description:
This command is used to create regions by the intersection of a plane and solids, surfaces or meshes.
This command can create a 2D region object for 3D objects (contains 3D solids, surfaces and meshes), but it can not move the section plane (it is applied on section plane objects created by the SECTIONPLANE command).

## Command Prompts:
```
Select object:
Specify start point of section or [Object/Z axis/View/XY/YZ/ZX/3 points] <3 points>:
```
## **Select object**
Selects one or more 3D objects. If selecting more objects, it separately creates regions for each object.
## **Object**
Aligns the sectioning plane with a circle, ellipse, elliptical arc, 2D spline or 2D polyline segment.
## **Z axis**
Defines the sectioning plane by two points; one point passes through the sectioning plane and another point is on the Z axis (normal).
## **View**
Aligns the sectioning plane with the current view of viewport.
## **XY**
Aligns the sectioning plane to the XY plane of the current UCS.
## **YZ**
Aligns the sectioning plane to the YZ plane of the current UCS.
## **ZX**
Aligns the sectioning plane to the ZX plane of the current UCS.
## **3 points**
Defines the sectioning plane by 3 points.
