# DIMTM System Variable [GstarCAD 2017](Help%20System/GSTARCAD/2017/Index.md) → [System Variables](Help%20System/GSTARCAD/2017/System%20Variables/(System%20Variables).md) → [D](Help%20System/GSTARCAD/2017/System%20Variables/D/(D).md) ## Function Description: The DIMTM system variable is used to control the minimum tolerance limit for dimension text when the DIMTOL or DIMLIM is on. | | | | --- | --- | | Type | Real | | Saved in | Drawing | | Initial value | 0.0000 | The DIMTM system variable could recognize a value with symbols. If the DIMTOL is on and the settings of DIMTP and DIMTM are the same, it could create a tolerance value. If the values of DIMTM and DIMTP are different, the upper tolerance is drawn above the lower, and a plus sign is added to the DIMTP value if it is positive. --- ## Other versions with matching text [GstarCAD 2016](../../../2016/System%20Variables/D/DIMTM%20System%20Variable.md) · [GstarCAD 2018](Help%20System/GSTARCAD/2018/System%20Variables/D/DIMTM%20System%20Variable.md) · [GstarCAD 2019](Help%20System/GSTARCAD/2019/System%20Variables/D/DIMTM%20System%20Variable.md) · [GstarCAD 2020](Help%20System/GSTARCAD/2020/System%20Variables/D/DIMTM%20System%20Variable.md) · [GstarCAD 2021](Help%20System/GSTARCAD/2021/System%20Variables/D/DIMTM%20System%20Variable.md)
