List Editor - Multi-property Parameter List

You use a Multi-property Parameter list to set the value for multiple properties in a part or assembly document, based on the current value of a specified parameter in the model. The list editor enables you to manage the values assigned to properties and their association to a specific range of values for the parameter.

After creating a Multi-property Parameter list, you assign the list to multiple properties in the iPropWiz configuration editor.

The list is always shown sorted by Order (#). You can reorder items in the list by using a common drag and drop workflow. See the Drag and Drop in Grids page for more information.

	Parameter
	The name of the model or user parameter that is evaluated. The name entered must be a case sensitive match to a parameter name in the model.

Comparison

A Multi-property Parameter list works by examining the value of a specified parameter in a part or assembly model. When the value of the parameter changes, the current iPropWiz configuration is evaluated to see if the parameter is included in any assigned Multi-property Parameter lists. If so, the value comparisons in the list are evaluated, in the order they appear in the list, to see if the current value of the parameter (in the parameter's units) meets the value criterion specified in the list row. If the parameter value meets the conditions of the comparison, the values in the secondary value list for that row are assigned to their associated properties.

You create a value comparison by selecting a single or range comparison operator, and entering values for the comparisons. The resulting value criterion is displayed in the Description column.

Using the above image, the evaluation of a parameter value change would proceed as follows:

The value of the Length parameter in a part changes to 53.25 in. The comparison always considers the parameter value in the units specified for the parameter.

The first comparison in the list, If Length < 42, is evaluated and since the answer is false, the comparison moves to the next row in the list.

The second comparison, If Length >= 42 AND Length <80, results in a answer of true. The comparisons stop and the value(s) from the secondary fields in this row are assigned to their associated properties.

The third comparison (any any others) are never evaluated since the parameter value has already met the conditions of a previous comparison.

	Comparison Values
	Values used in the parameter value criterion. If the comparison is singular ( i.e less than "<' or equal '=' ), only the Val1 comparison value is entered. If the comparison contains the & character, both Val1 and Val2 are required.

	Description
	The description field in a Multi-property Parameter list is treated differently than in other lists. The Description field is always shown and is not editable. The description is automatically generated from the comparison and comparison values in the row. The description provides a readable definition of the comparison applied to the value of the selected parameter.

	Secondary Value Lists
	See the Comparison section above for a description of how secondary value lists are applied in a Multi-property Parameter list. See the Multi-property Lists page for more information on managing secondary values and assigning secondary values to Inventor iProperties.

	Insertion Row
	Select a comparison operator from the drop-down list, and enter comparison values to complete the parameter value criterion. Enter values or select a list for each secondary value list.

Tips: You can obtain an OR comparison by placing two singular or range comparisons in order. For example, you could check if Length < 10, then in the next line check for Length > 100 in the next row of the list.

You can create lists that have default values by ensuring that all possible values for the parameter are included in the comparisons.

Notes: List additions and edits are saved to disk when you save the current configuration from the iPropWiz Configuration Editor.

If the value of the parameter does not meet any of the value criteria, the properties associated with the secondary fields are editable in the iPropWiz Property Editor
