    Syntax

    tolSet = addComponentPositionTolerance(tolSet,propertyName,value)
    tolSet = addComponentPositionTolerance(tolSet,propertyName,value,TargetIndex=targetIdx)

    Description

    Add-On Required: This feature requires the Optical Design and Simulation Library for Image Processing Toolbox add-on.

    tolSet = addComponentPositionTolerance(tolSet,propertyName,value) adds a tolerance for the component position property specified by propertyName to the tolerance set tolSet. The tolerance applies to all top-level components. The tolerance set, tolSet, is an opticalToleranceSet object. This function adds a ComponentPositionTolerance object to the Tolerances property of tolSet and appends the details of the tolerance to the ToleranceTable property of tolSet.

    example

    tolSet = addComponentPositionTolerance(tolSet,propertyName,value,TargetIndex=targetIdx) applies the tolerance to only the components specified by targetIdx. This function does not support sub-component tolerancing.

    This example uses:

    Open Live Script

    Import an optical system into the workspace.

    opsys = zmximport("PhotographicLens.zmx");

    Create an empty optical tolerance set.

    tolSet = opticalToleranceSet;

    Add tolerances to the tolerance set.

    tolSet = addSurfaceRadiusTolerance(tolSet,0.05);
tolSet = addSurfaceConicConstantTolerance(tolSet,[-0.01 0.01],TargetIndex=2);
tolSet = addSurfacePositionTolerance(tolSet,PositionX=0.1);
tolSet = addSurfaceTiltTolerance(tolSet,TiltX=[-0.5 0.5],TargetIndex=3);
tolSet = addSurfaceAsphericTolerance(tolSet,0.05,4);
tolSet = addComponentPositionTolerance(tolSet,PositionX=0.1);
tolSet = addComponentTiltTolerance(tolSet,TiltY=[-0.2 0.2],TargetIndex=2:8);
tolSet = addComponentMaterialTolerance(tolSet,Nd=0.05,TargetIndex=2:8);

    Inspect the tolerance set.

    Input Arguments

    collapse all

    Tolerance set to which to add the tolerance, specified as an opticalToleranceSet object.

    Component position property to which to apply the tolerance, specified as "PositionX", "PositionY", or "PositionZ".

    Data Types: char | string

    Tolerance value, specified as a numeric scalar or a 1-by-2 numeric vector of the form [min max].

    • Scalar — Specifies a percentage tolerance relative to the nominal value.

    • 1-by-2 vector — Specifies an offset tolerance range [min max] relative to the nominal value.

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

    Component indices to target, specified as a vector of positive integers. By default, the tolerance applies to all top-level components. This function does not support tolerancing for nested components.

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

    Output Arguments

    collapse all

    Updated tolerance set, returned as an opticalToleranceSet object with the component position tolerance appended. This function adds a ComponentPositionTolerance object to the Tolerances property of tolSet and appends the details of the tolerance to the ToleranceTable property of tolSet.
