# 3DALIGN Command [GstarCAD 2018](Help%20System/GSTARCAD/2018/Index.md) → [Commands](Help%20System/GSTARCAD/2018/Commands/(Commands).md) → [3D](Help%20System/GSTARCAD/2018/Commands/3D/(3D).md) The 3DALIGN command is used to align selected object to other object in 2D and 3D space. ## Command Access: > **Ribbon:** 3D\> 3D Operations \> 3D Align > **Command:** 3DALIGN ## Command Prompts: > Select object: > Specify source plane and direction... > Specify base point or \[Copy\]: > Specify second point or \[Continue\] \<C\>: > Specify third point or \[Continue\] \<C\>: > Specify destination plane and orientation... > Specify first destination point: > Specify second destination point or\[exit\] \<X\>: > Specify third destination point or\[exit\] \<X\>: ## Function Description: Users could align selected object by specifying one point, two points or three points as source points and specifying one point, two points or three points as destination points. ![](Help%20System/GSTARCAD/2018/assets/GCAD_GCR/images/3DALIGN-1.GIF) **Relative Glossary:** **Select object:** It will move and rotate the selected object to make the source object in 3D aligned to the base point, X axis and Y axis of destination. The 3DALIGN command could be used in dynamic UCS (DUCS), so the selected object could be dynamically dragged and aligned to face of destination solid. **Base point:** The base point of source object will be moved to the base point of destination object. **Second point:** The second point specifies the new X axis direction for a plane; this plane is parallel to the current UCS. If pressing ENTER rather than specifying the second point, it assumes that the X axis and the Y axis are parallel to current X axis and Y axis of current UCS. **Third point:** The third point will completely specify the X axis and Y axis direction for source object, those two direction will be aligned to the destination plane. **First destination point:** The first destination point defines the destination of source object. **Second destination point:** The second destination point specifies the new X axis direction for a plane; this plane is parallel to the current UCS. If pressing ENTER rather than specifying the second point, it assumes that the X axis and the Y axis are parallel to current X axis and Y axis of current UCS. **Third destination point:** The third point will completely specify the X axis and Y axis direction for destination object. ## Other versions with matching text [GstarCAD 2016](../../../2016/Commands/3D/3DALIGN%20Command.md) · [GstarCAD 2017](../../../2017/Commands/3D/3DALIGN%20Command.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/Commands/3D/3DALIGN%20Command.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/Commands/3D/3DALIGN%20Command.md) · [GstarCAD 2021](Help%20System/GSTARCAD/2021/Commands/3D/3DALIGN%20Command.md)
