PCB Layout CAD : Draw

Dimension

There are the following types of Dimensions.

In addition, for components, there is an auto dimension creation function for automatically creating Pad Dimensions, Assembly Dimensions, etc.

Line Dimension Rectangle Dimension Circle Dimension Pad Dimension
Draws a Line Dimension.
Click a line.
Draws a Rectangle Dimension.
Click a side of a rectangle.
Draws the Diameter and Radius Dimension for Circles and Arcs.

Click a circle.
Draws the Pad Diameter Dimension.

Click a pad.

 

2 Point Distance Dimension Free Dimension Leader Line Angular Dimension
Draws a Dimension for measuring the distance between two objects.
 
Draws a Dimension for two arbitrary coordinates.

Click two points for the distance you want to measure.
Draws a Leader Line.
Click a start point and end point for the Leader Line that you want.
Draws a Dimension showing the Angle of two lines.

Click two lines.

 

Corner Dimension

Draws a Dimension for the angle length.
Click the side of the angled side.
(Dimensions for C cut and Rounding can be drawn.)

In addition to the basic dimensions explained here, confirm the functions for "Create Component Dimension Automatically", which executes auto creation based on the Component Pad and Assembly, and for "Create Board Outline Dimension Automatically", which executes auto creation based on the Board Outline.

There are several other ways to perform this. Refer to About Executing Menus.

When [Update Component/Replace Component] is executed for a dimension that was created for a component on a PCB design, the creation target will be reset and it will be deleted.

Display Digit

Sets the Display Digit for the decimal places. Fractions are rounded off.

Example) For "2", "7.62". For "3", "7.620".

Zero Suppression

Use this field to determine whether trailing zeros should be suppressed or not. Use the drop-down list to choose from the following:

None : The dimension value will be displayed according to the number of digits set in the Display Digit field.
Trailing : No trailing zeros will appear in the dimension value.
Ex.) When the number of display digits is 4 and the measurement value is 0.6350, the value will be 0.635.
