"tolLow"

Defines the lower tolerance value on the scale.

Synopsis

setValue(string shape, "tolLow", float lowValue);

getValue(string shape, "tolLow", float &lowValue);

shape.tolLow(float lowValue);

Parameters


Parameter	Description
shape	Name of the object
lowValue	Lower tolerance value

Description

This attribute can be used to specify the lower tolerance value on the scale. The attribute "lowValue" is not an absolute value, however, but a percentage of the reference value defined with "refValue". Note, however, that the specified percentage still refers to a tolerance. Thus for a reference value of 50 and lowValue==60, the lower tolerance range would be 30 but the lower tolerance value would be 20 (50-30), that is, only values below 20 are invalid.

Example

see "refOrigin"
