The Linear Dimension (Parallel)
command, in eCADSTAR PCB Editor,
allows you to input a parallel series of linear dimensions to the drawing
layer of the active layer. This is illustrated in the following example.
The dimensions are created from the reference start point that you define
on the canvas. You can change the properties of the dimension line by
selecting it on the canvas, and then editing the settings in the Properties
panel. To change the dimension value and the position of the dimension
line, set Edit dimension to ON,
and then drag the dimension line on the canvas. Launch this command by
clicking Draw > Linear Dimension > 
Parallel
on the ribbon in eCADSTAR PCB Editor.
This command is only available in 2D View
mode.
View dimension lines on the canvas as follows.
- In the Layer
Settings panel, select
Visible
drawing layer in the Drawing layer
section. To display this column in the Layer
View table, select Show in grid
in the Drawing layer section. - For the relevant layer in the Layer
Settings panel, Layer name column,
select theVisible drawing layer check box.

Positive and negative manufacturing tolerances are displayed on the canvas for dimension lines that you add using a dimension command. This is illustrated in the following example.
The Positive Tolerance and Negative Tolerance fields are made available. The values that you specify in these fields are displayed in the relevant dialog for every dimension command. |
| OFF | Tolerances are not displayed on the canvas for dimension lines. The Positive Tolerance and Negative Tolerance fields are made unavailable. |
If you change the units in a design, the tolerances that you specify are not changed.
Positive Tolerance
| Value | Description |
|---|---|
| Real number greater than or equal to 0. | Specify the positive tolerance for all dimension lines that you add using a dimension command. The value that you specify is displayed on the canvas, with a "+" prefix. It is displayed after the dimension value. |
Negative Tolerance
| Value | Description |
|---|---|
| Real number greater than or equal to 0. | Specify the negative tolerance for all dimension lines. The value that you specify is displayed on the canvas, with a "-" prefix. It is displayed after the dimension value. |
