# Dimension Offsets and Joining
### Join Dimensions
This feature joins selected dimensions to one dimension chain. The first selected dimension indicates the final position of the joined dimension chain. The dimension type will be the same as the first selected dimension type.
To use it, click **Join Dimension** and then pick the dimensions that you want to join one by one. To finish the selection, press **Esc**. All parallel dimensions will be connected to one.
### Change dimension offset from wall

**Change Dimension Offset from Dimension** - changes selected dimension's offset from other selected dimension. This offset is defined in dimension’s type properties under the **Dimension Line Snap Distance** parameter.
First, a dimension that will move has to be selected, and then the other dimension to offset from.
