PCB Layout CAD : Various Convenient Functions

Ruler

The ruler feature is a function for measuring the distance between two points.
By setting a "Measurement Item" and "Measurement Target", it is possible to measure various target distances.

A ruler calculates the shortest distance between objects excluding arbitrary points, so if you zoom in to the screen, the measurement results may be shown outside of the screen.
Keep this in mind.

Measurement Item

There are three types of Measurement Items.

Item Description

Any Two Points

It is possible to select points freely as a reference point for measurement.

Object

It is possible to specify an object as a reference point for measurement.

Segment

It is possible to specify a segment as a reference point for measurement.
Ex.)One side of a polygon plane.

 

Measurement Target

There are two types of measurement targets. You can also combine different measurement targets.

Center Edge
The center of an object selected by a click will be a measurement target.
The shortest distance is measured.
Ex.) Distance between the centers of a board outline and a drill
The edge of an object selected by a click will be a measurement target.
The shortest distance is measured.
Ex.) Pad resist interval

 

 

Other Settings
Item Description

Target Layer of Pad

Select a layer of pad as a measurement target.

Advanced Settings

Placing a check permits to configure advanced settings.

Delete Ruler upon Exiting Mode

It is possible to set whether to delete created rulers upon exiting ruler mode.
Checked    : Deletes all created rulers on a sheet upon exiting ruler mode.
Unchecked : Keeps all created rulers on a sheet after exiting ruler mode.

Show All Target Layer of Pad

If checked, all target layers of pad are shown in the drop-down list of "Target Layer of Pad".

Pitch

It is possible to set the pitch of a ruler.

Color

It is possible to set the color of a ruler.

 

Making a Measurement

The following will explain how to measure distance between two points with a Ruler.

Any Two Points
The following will explain how to measure distance between freely selected two points.
 
(1) Select [Edit] => [Ruler].

 
(2) As a Ruler dialog will open, select "Any Two Points".
 
(3) Start a measurement by clicking on an arbitrary point.
 
(4) Finish a measurement by clicking on an arbitrary point.

 


 

Center
The following will explain how to measure distance between the centers of objects selected by clicks.
 
(1) Select [Edit] => [Ruler].

 
(2) As a Ruler dialog will open, select a measurement item from "Measurement Item".
(3) Select "Center" in "Measurement Target".
 
(4) Start a measurement by selecting a measurement target by a click.

*The measurement start point is the centerline of the target.

 
(5) Finish a measurement by selecting a measurement target by a click.

*The measurement end point is the centerline of the target.

 

 


Edge
The following will explain how to measure distance between the edges of objects selected by clicks.
 
(1) Select [Edit] => [Ruler].

 
(2) As a Ruler dialog will open, select a measurement item from "Measurement Item".
(3) Select "Edge" in "Measurement Target".
 
*If selecting a pad as a measurement target object, choose a target layer at "Target Layer of Pad".
 
(4) Start a measurement by selecting a measurement target by a click.

*The measurement start point is the edge of the target.

 
(5) Finish a measurement by selecting a measurement target by a click.

*The measurement end point is the edge of the target.

 

 


Combination of Measurement Targets
It is possible to combine measurement targets. Here, the following will explain how to measure distance between the "Edge" of a pad and the "Center" of a route as an example.
 
(1) Select [Edit] => [Ruler].

 
(2) As a Ruler dialog will open, select a measurement item in "Measurement Item".
(3) Select "Edge" in "Measurement Target".
(4) Select a measurement target layer of a pad at "Target Layer of Pad".
 
(5) Start a measurement by selecting a measurement target by a click.

*The measurement start point is the edge of the target.

 
(6) Back to the Ruler dialog, and select a measurement item in "Measurement Item".
(7) Select "Center" in "Measurement Target".
 
(8) Finish a measurement by selecting a measurement target by a click.

*The measurement end point is the centerline of the target.

 

Deleting Rulers

The method to delete drawn rulers is as follows.

Deleting Rulers
The following will explain how to delete drawn rulers.
 
(1) Right-click and select [Erase Ruler].

 

Exiting Ruler Mode

The methods to exit ruler mode are as follows.

Method1: Right-click and select "Cancel".
Method2: Press a "Escape" key on a keyboard.
