# DIMSPACE Command [GstarCAD 2021](Help%20System/GSTARCAD/2021/Index.md) → [Commands](Help%20System/GSTARCAD/2021/Commands/(Commands).md) → [D](Help%20System/GSTARCAD/2021/Commands/D/(D).md) The DIMSPACE command is used to modify the space of linear dimensions or angular dimensions. ## Command Access: > **Ribbon:** Annotation \> Dimension \>DIMSPACE > **Menu:** Dimension \>Dimension Space > **Command:** DIMSPACE ## Command Prompts: > Select base dimension: > > Select dimension to space > \<Auto\>: > Enter value or \[Auto\]\<Auto\>: ## Function Description: Users could specify equal space for parallel dimension extension lines. They could also specify its space to 0 to make linear dimension or angular dimension alignment. This command is only applied on parallel dimensions or angular dimension which sharing one vertex.   **Relative Glossary:** **Enter value:** Enter value for space and apply it on selected dimensions. If the inputted value is 0, the selected linear dimension and angular dimension will be aligned. **Auto:** Automatically calculate space of dimension extension lines. It is based on its baseline dimension style and its text height. The calculated space is twice of its dimension height. ## Other versions with matching text [GstarCAD 2016](../../../2016/Commands/D/DIMSPACE%20Command.md) · [GstarCAD 2017](../../../2017/Commands/D/DIMSPACE%20Command.md) · [GstarCAD 2018](Help%20System/GSTARCAD/2018/Commands/D/DIMSPACE%20Command.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/Commands/D/DIMSPACE%20Command.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/Commands/D/DIMSPACE%20Command.md)
