# SKETCH Command [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 a series of freehand line segments. Users can use this command to create irregular boundaries. Before this, users should specify the object type (line, polyline, or spline), increment, and tolerance firstly. ## Command Access: > **Icon:** / > **Menu:** / > **Ribbon:** / > **Toolbar:** / > **Command:** SKETCH > **Alias:** / ## Command Prompts: ``` Record increment <1.0000>: Sketch. Pen/eXit/Quit/Record/Erase/Connect. ``` ## **Record increment** Defines the length of each freehand line segment drawn by sketching. To create a line, the moving distance of the pointing device must greater than the increment value. Users can use the SKETCHINC system variable to specify the increment value. --- **Related References：** - [Commands about Linear Geometric Objects (GstarCAD 2026)](../../../2026/Commands/00%20Command%20Groups/Commands%20about%20Linear%20Geometric%20Objects.md) **Related Tasks：** - [To Draw Freehand Sketches (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Draw%20Freehand%20Sketches.md) - [To Draw Lines (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Draw%20Lines.md) - [To Draw a Rectangle (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Draw%20a%20Rectangle.md) - [To Draw Polylines (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Draw%20Polylines.md) --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences_S/SKETCH.html) · © Gstarsoft Co., Ltd.
