Element Filter

The eVolve Element Filter

The purpose of the Element Filter feature provides highly customizable and storable rule sets which help users to quickly select, isolate, hide, halftone or apply transparency to specific items in a model. This ability not only allows for quick view changes, but also fully tailor all evolve and even Revit commands to the users needs.

The Element Filter Palette

  1. Reset View: Used after applying the Isolate, Hide, Make Half Tone or Make Transparent actions with the filter. The Restore View button will restore the view to it's pre-filtered state
  2. New Filter: Loads the Filter Designer
    1. Enter a filter name
    2. Select which category or categories to apply these filters to
    3. Under the Rules tab, users can define the AND/OR statements for the parameters based on the categories chosen
    Note: After defining the AND/OR statement, click on Add Condition to get started with the new rule
    Tip: If a needed parameter is not available, then a shared parameter may need to be created. Use the eVolve MEP Parameter Sync tool.
    Tip: One of the "Input Type" options is to prompt for value. When set, a dialog will ask for the "Value" when the user clicks on the rule, making the rule more widely usable.
    1. The Options tab allows users to define the default action to the rule. If this is set to anything other than "Select Action" then the action defined will be automatically applied after a double click on the rule within the palette
  3. Modify Filter
  4. Duplicate Filter
  5. Delete Filter
  6. Export Filter(s): Select the filter or filters to export
Note: If multiple filters are selected, they will all be included in the same export file
  1. Import Filter(s): Loads a previously made filter file
  2. Help: Links to this Help Document
  3. Network Settings: By default, these rules are stored locally for each user. Setting the network path ensures that everyone is looking at the same rule set

Creating Element Filters

  1. From the Filter Designer window, Enter a Filter Name in the provided field
  2. Select the categories for this filter to apply to. It is always easiest to start small, so consider starting by selecting one category to be sure that the new filter works before applying other categories
  3. Click on the Rules tab and start to build a rule. Click the Add Condition button to create the first condition in the rule set
    1. The first option in the condition is to select a parameter
If only a few parameters, or none, appear in the drop-down, it is because multiple categories have been selected and the parameter needed may not exist in all categories that were selected. To correct this, go back and reduce the number of categories for this rule to apply to.  The other categories can always be added back later. A missing parameter name can be entered manually, but it must be exact.

4.       Select an operator. The most common operator is "Contains" because users only have to type in partial matches

5.   Select an Input Type

Input Type Options:

  • Constant Value: The user will type in the criteria in the Value field. For example, if searching for RMC Fittings, consider the "contains" operator, "constant value" input type and RMC in the value field
  • Prompt for Value: This option will force a dialog in front of the user for what Value to be used. If something is typed in the Value field of the rule, then the text is used in the dialog's prompt or in the Revit status bar, depending on the Input Type option
  • Compare to Parameter: Use this to look for matches of two parameters
  • Single Element Selection: When the rule is activated, only one element in the model can be selected, then the rule acts on that object. For example, a user may want to select all objects that match the same service type or service abbreviation, therefore the rule would ask the user to select one object and find all matches in the model
  • Multiple Element Selection: To duplicate the old Hide button functionality, the rule must allow the selection of multiple elements. This setting allows users to pick objects on different services and will apply a Hide action on all elements with the same service abbreviation as the objects selected

6.  To finish the rule, the Value field will be completed. In the example, we are using Element Selection as our input type, the text in the Value field is used in the user prompt when the rule is used

7.   Click the Options tab and apply a default action to the rule

 Options are:

  • Select Action: This is the default action which forces the user to select what action to apply at the time the rule is activated. If Default Filter Action is not selected this will be the action used.
  • Select: Select the elements to run any eVolve or Revit command on the selected objects
  • Isolate: Isolates the elements in the current view
  • Isolate (Temporary): Creates a new temporary view and isolates the elements
  • Show: Shows previously hidden elements in the current view
  • Hide: Hides the elements from the current view
  • Make Halftone: Applies halftone to the selected elements
  • Make Transparent: Applies transparency to the selected elements

Using the Element Filters

There are 3 ways to use the filters once they have been created:

  1. Select the filter then click on the action button to apply the default action. If a default has not been applied then this button will supply a drop down of options
  2. If a default action has been applied, double click on the rule to activate it
  3. Define a hotkey
    1. In the "HotKey" column enter the desired hot key value
    2. If not done already, enable the Element Filter hotkey in Revit options.
    3. Enter the Element Filter hotkey then the filter rule hot filter to activate the rule

eVolve Element Filter Hot Keys

To increase efficiency and productivity, the new Element Filter feature includes the ability to assign Hot Keys to user created filters. From the main Element Filter window, enter the desired HotKeys in the HotKey column next to each Filter Name. While in a project, type EF to bring up the HotKeys Listener. Once activated, the user has several seconds to enter the desired filter hotkey and apply its associated filter.

Note: If not done already, enable the Element Filter hotkey in Revit options. Consider assigning it to EF to easily remember the Element Filter HotKey for activating the HotKey Listener.
