# DIMTP System Variable [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [System Variables](Help%20System/GSTARCAD/2022/System%20Variables/(System%20Variables).md) → [D](Help%20System/GSTARCAD/2022/System%20Variables/D/(D).md) **Function Description:** The DIMTP system variable is used to set the maximum 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 can recognize a value with symbols. If the DIMTOL is on and the settings of DIMTP and DIMTM are the same, it can 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.
