# DIMBASELINE Command [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [Commands](Help%20System/GSTARCAD/2022/Commands/(Commands).md) → [D](Help%20System/GSTARCAD/2022/Commands/D/(D).md) ## Function Description: This command is used to create a linear, angular or coordinate dimension from the baseline of the previous or selected dimension. The default spacing between baseline dimensions can be set from the Lines tab of the Dimension Style Manager dialog box (DIMDLI system variable). If no dimension is created in the current session, you are prompted to select a linear, ordinate or angular dimension to use as the base for the baseline dimension. To end the command, press Enter twice or press Esc. The current dimension style determines the appearance of the text. By default, the dimension style of the baseline dimension is inherited from the previous or selected dimension. You can use DIMCONTINUEMODE to change the default to use the current dimension style. ## Command Access: > **Icon:** >  > **Menu:** Dimension \> Baseline > **Ribbon:** Annotation \> Dimension \> DIMBASELINE > **Toolbar:** Dimension \> DIMBASELINE > **Command:** DIMBASELINE > **Alias:** DIMBASE/DBA ## Command Prompts: Select base dimension: Specify a second extension line origin or \[Undo/Select\] \<Select\>: ## Select base dimension Specifies a linear, ordinate or angular dimension. Otherwise, the program skips this prompt and uses the dimension object that was last created in the current session. ## Second extension line origin If the base dimension is linear or angular, this prompt is displayed. By default, the first extension line of the base dimension is used as the extension line origin for the baseline dimension. To override this default behavior, explicitly select the base dimension; the extension line origin becomes the extension line of the base dimension closest to the pick point of the selection. When you select a second point, the baseline dimension is drawn and the Specify a Second Extension Line Origin prompt is redisplayed. To end the command,  press Esc. To select another linear, ordinate or angular dimension to use as the basis for the baseline dimension, press Enter. ## Feature location If the base dimension is ordinate, this prompt is displayed. Uses the endpoint of the base dimension as the endpoint for the baseline dimension; you are prompted for the next feature location. When you select a feature location, the baseline dimension is drawn and the Specify Feature Location prompt is redisplayed. To select another linear, ordinate or angular dimension to use as the basis for the baseline dimension, press Enter. ## Undo Undoes the last baseline dimension entered during this command session. ## Select Prompts you to select a linear, ordinate or angular dimension to use as the base for the baseline dimension.
