Consider the Units Of Measurement

It is important to consider units when setting rules directly in a template. If you use a constant value in a rule, always specify the units to avoid ambiguity; for example,

Rule Set Pos (N (CDPR HEIG + 15 mm)

otherwise the current units will be assumed.

Remember that, in a metric catalogue, items are always dimensioned in mm, so a reference to these in a rule must take this into account. For example, if you use the RPROP pseudo-attribute to extract the value of a catalogue parameter, the result will always be in mm, so you must include a conversion factor in your rule if you are designing using non-metric units.

Note: This does not apply if the catalogue value is defined within a design dataset, because units are handled internally within datasets.
