Adding Measurement Points

How to Execute

Run Directly on Screen

Switch to Add Measurement mode, select the direction, type, etc. of the measurement point in the Measurements tab toolbar of Measurement Panel, then left-click on screen.

The measurement points are saved to Measurement Panel and displayed on screen.

Right-click on the displayed measurement point to open the context menu, containing the following items in addition to the default context menu items.

Direction and Type of Measurement Point

The direction and type of the measurement point can be specified from Direction on the Measurements tab toolbar.

Icon	Item	Action
	0 degree	Create a 0 degree measurement point.
	45 degree	Create a 45 degree measurement point.

	135 degree	Create a 135 degree measurement point.
	Box	Create measurement points in two directions, 0 and 90 degrees.
	Any Angle	Create a measurement point of any angle. Specify the angle in the Angle for Measurement dialog which opens when it is selected.
	Horizontal Hole	Create a 0 degree measurement point at Dot/Hole.
	Vertical Hole	Create a 90 degree measurement point at Dot/Hole.
	Box Hole	Create a measurement point measuring both 0 and 90 degrees at Dot/Hole.
	Edge-Edge	Create a measurement point from line end to line end. You need to specify two points.
	Auto Angle	Create a measurement point with direction perpendicular to the edge nearest to the point.
	View	Create a measurement point to check the figure at the selected point.
	Corner Round	Create a measurement point at a corner.
	Point-Point	Create a measurement point between any two points. You need to specify two points.
	Auto Hole Short	Create a measurement point on the short edge of Dot/Hole boundary box.
	Auto Hole Long	Create a measurement point on the long edge of Dot/Hole boundary box.
	Line Space Point-Point	Create measurement points in lines and spaces between any two points. You need to specify two points.
	Area	Create a measurement point to measure an area of figure on specified point.
	Area by 2 Points	Create measurements point to measure areas of figures in specified area. Created measurement points are grouped. You need to specify two points.

Tone of the Measurement Point

The tone of the measurement point is specified from Tone on the Measurements tab toolbar.

Icon	Item	Action
	Auto	Create a measurement point at the selected point.
	Line	Create a measurement point on the figure.
	Space	Create a measurement point in space.
	Pitch Up-Up	Create a measurement point from the start of one figure to the start of the next.
	Pitch Down-Down	Create a measurement point from the start of one space to the start of the next.
	Target CD Width	Create a measurement point on a figure with the specified length. Specify the Target CD and the tolerance in the Target CD dialog which opens when it is selected.
	Target CD Space	Create a measurement point in space with the specified length. Specify the Target CD and the tolerance in the Target CD dialog which opens when it is selected.
	Target CD Pitch Up-Up	Create a measurement point from the start of one figure to the start of the next with the specified length. Specify the Target CD and the tolerance in the Target CD dialog which opens when it is selected.
	Target CD Pitch Down-Down	Create a measurement point from the start of one space to the start of the next with the specified length. Specify the Target CD and the tolerance in the Target CD dialog which opens when it is selected.

Search Width

Search Width can be switched from Search Width on the Measurements tab toolbar.

Icon	Item	Action
	No Search	Add a normal measurement point.
	Min	Add a measurement point at the minimum width around the specified coordinates.
	Max	Add a measurement point at the maximum width around the specified coordinates.

Other Settings of Measurement Points

With Jog

Creates a measurement point on a figure that contains jogs.

Icon	Item	Action
	With Jog	Specify whether to tolerate jogs. You can specify two tolerances in um units.

When With Jog is specified, the jog on the figure is smoothed, and the measurement point is created for the smoothed figure. The target of smoothing are edges that is within the range specified by With Jog, based on the line length of the measurement point. The smoothing is performed up to two times. The first one is done using the first tolerance value and the original measurement length. The second one uses the second tolerance value and the weighted average value of the measurement length from the first smoothing. The second smoothing is skipped if the tolerance value is 0.

Jog Type

When With Jog is specified together, the measurement point is created based on the smoothed figure and the actual figure.

Icon	Item	Action	Result
	Average	Create a measurement point for the smoothed figure.
	Min	Create a measurement point using the smallest length of the actual figure which is the source of the smoothed figure as measurement line.
	Max	Create a measurement point using the largest length of the actual figure which is the source of the smoothed figure as measurement line.

Assist Size

Ignore assist line or space when creating a measurement point.

Icon	Item	Action
	Off	Create a measurement point without ignoring any figures.
	Assist Line	Create a measurement point ignoring small figures. Can only be created inside space.
	Assist Space	Create a measurement point ignoring small spaces. Can only be created inside figure.

Run from the Create Measurement Point Dialog

Right-click the blank area of the datalist in Measurements tab of Measurement Panel to open the Create Measurement Point dialog.

Enter the coordinates and press OK to add the measurement point.

Run with Measure Points File

Click the icon on Measurement Panel and select Load Measure Points File to open the Load Measure Points dialog.

Select a Measure Points File and press OK to append measurement points described in the file to the datalist.

Refer to Measure Points File page.

Output Measurement Points to a File.

The measurement points in the datalist can be saved to a text file.

Click the icon on Measurement Panel and select Save as Measure Points File to open Save Measure Points as dialog.

Specify the output file name and press OK to save. The output has the following format:

# Measure Points File Created by libebv at DATE nebv VERSION
Out-Origin OUT-ORIGIN 0, 0
# Alignment mark
# Measurement points
1 CD X 125.804, 162.637
2 CD Y 107.876, 158.599
# End of File

Run from the Command Line

Specify --measure-file option with a Measure Points File to add alignment marks after startup. You can also specify the filename to save measurement points (including alignment marks) using --measure-file-out option.

By specifying as follows, measurement points and alignment marks will be created for figure_file, and the results will be output to measure_points.txt.

$ nebv --measure-file=/path/to/measure_point_file.txt --measure-file-out=/path/to/measure_points.txt /path/to/figure_file

Refer to Measure Points File page.

See --measure-file, --measure-file-out in Boot Options page.

Similarly, you can specify the filename to save CD Results File using --cd-file option.

$ nebv --measure-file=/path/to/measure_point_file.txt --cd-file=/path/to/cd_results_file.txt /path/to/figure_file

See --cd-file in Boot Options page.
