DimBaseline command in CAD

DimBaseline command in cad (dba command in cad): it is the command to specify the dimension in parallel with existing dimension.

Command: dimbaseline
Shortcut command: dba
Menu: dimension\baseline

When specifying the parallel dimension series by Dimbaseline command, the dimension that will be specified (straight dimension, angle, coordinate) gets the same first extension line with the dimension that has just been specified or the existing dimension on drawing (dimension standard or design standard). The dimension lines with a distance are fixed by DIMDLI variable (according to Vietnamese Standard, it is longer than 7mm) or enter the value in box Baseline Spacing on page Lines and Arrows of dialog box New Dimension Styles or Override Current Style.

1. Dimension at the same standard with the dimension which has just been specified.

If you specify the dimension series in parallel with the dimension which has just been specified (P1P2 dimension), please follow the below instructions:

Command : DBA↵ or Dimbaseline

Specify a second extension line origin or [Undo/Select] <Select>: origin of the second extension line P3 Dimension text = 70
Specify a second extension line origin or [Undo/Select] <Select>: origin of the second extension line P4
Specify a second extension line origin or [Undo/Select] <Select>: Continue to choose origin of the second extension line P5
Specify a second extension line origin or [Undo/Select] <Select>: Continue to choose origin of the second extension line P6
Specify a second extension line origin or [Undo/Select] <Select>: Press ESC or press ENTER 2 times.

2. Choose standard dimension line.

If you want the dimension series in parallel with the existing dimension (not the dimension which has just been specified), at the first prompt line you press ENTER. Then the below prompt line will appear:

Command : DBA↵ or Dimbaseline

Specify a second extension line origin or [Undo/Select] <Select>:↵
Select base dimension: Choose the standard extension line is the first extension line
Specify a second extension line origin or [Undo/Select] <Select>: origin of the second extension line P3
Specify a second extension line origin or [Undo/Select] <Select>: origin of the second extension line P4
