Measure Dimensions by Features

Description

This Step is used to perform dimensional measurements from a feature point to a reference feature (reference point, reference line, or reference plane). It measures the distance between a point and a geometric feature such as a point or a plane.

Workflow

The process of configuring this Step is shown below.

Configure the input. Connect the ports manually or select the input(s) under Input in the parameter configuration panel.
Set the parameters according to the actual requirements.
Select the desired output(s) under Output. For an expandable output item, click ▶ and configure the Min and Max values of the acceptable range.
Run the Step and view output.

Parameter Description

Output Absolute Width / Length / Height

Output Absolute Width: When this is selected, the absolute value of the width (along the X-axis) between features will be output. Otherwise, a signed number will be output.
Output Absolute Length: When this is selected, the absolute value of the length (along the Y-axis) between features will be output. Otherwise, a signed number will be output.
Output Absolute Height: When this is selected, the absolute value of the height (along the Z-axis) between features will be output. Otherwise, a signed number will be output.

Output Description

Select the output item(s) according to the actual measurement requirements. Then, the corresponding data will be output after the Step is run.

If you select an expandable output item, you must expand it by clicking ▶, and then set the Min and Max values to determine the acceptable range. If the output value falls within the qualified range, the measurement is judged as passing (OK), or else it is judged as failing (NG).

Output Item	Description
Width	Point–point: The difference on the X-axis between the points. Point–plane: The difference on the X-axis between the point and a point on the plane with the same Y and Z values as the first point.
Length	Point–point: The difference on the Y-axis between the points. Point–plane: The difference on the Y-axis between the point and a point on the plane with the same X and Z values as the first point.
Height	Point–point: The difference on the Z-axis between the points. Point–plane: The difference on the Z-axis between the point and a point on the plane with the same X and Y values as the first point.
Distance	Point–point: The Euclidean distance between two points. Point–plane: The direct, Euclidean distance between the point and the nearest point on the plane.
Plane Distance	Point–point: The distance between two points. For profile data, the points are projected onto the XOZ plane. For surface data, the points are projected onto the XOY plane. Point–plane: The distance between the point and a plane. For profile data, the distance is projected onto the XOZ plane. For surface data, the distance is projected onto the XOY plane.
