Defining a spool

NOTE: The Create/Define Spool's predefined selection filter can be modified via the Selection Configuration. Please see the link in the Relevant Articles below.

  1. Starting Spool Name - The value specified will be applied to all spools created in the session. While the name may be alphanumeric, it must end with a numeric value.
  2. Create Sheets(s) on Finish - If enabled, eVolve will create the sheets for the defined spool(s) on finish using the title-block defined in step 3. If disabled, the spool sheets may be created within the Prefab Manager.
  3. Title Block - If Create Sheet(s) on Finish is enabled, the selected Title Block will be applied to all defined spools.
  4. Title Block Type - If applicable, this field is used to define the type of the selected title block family.
  5. Open Created Sheet(s) - if enabled, all created sheets will open after completing the session.

    NOTE: Spools may be defined and created at the same time, or they may be defined the created through the Prefab Manager.

Naming Spools

Spool names may be automatically generated by utilizing the parameters of the elements contained within the spool. While users can specify a value to apply to defined spools, the Starting Spool Name dialog is also a menu containing Revit and eVolve parameters. The parameters may be appended or chained together to provide a more descriptive name.

The bolded value below will generate the following spool names

Electrical Examples

  • <eE_ConduitRun_System> - <eV_LBS_Id> - 01
    • Branch - L1A-01
    • Feeder - L2B -02
    • Fire Alarm - L3C -03

Mechanical Examples

  • <eM_Service Name> - <eM_Service Type> - 01
    • Return Air 2wg - Rectangular Duct -01
    • Return Air 2wg - Rectangular Duct -02
    • Return Air 2wg - Round Duct -03

Define Spool

To Define a spool

  1. From the eVolve ribbon, click Define Spool from the Prefabrication panel.
  2. From the Create/Define Spool window, enter a spool name, select desired option, and click OK.
  3. From the drawing area, using a window selection or crossing window selection, chose the desired elements to spool and click Finish in the Options Bar.
  4. Continue to select elements to spool or click Finish in the Options Bar to complete the session.


When a new spool is created, the name is initially set by Revit. Any Parameter Sync based rules, including Colorizer, will execute against the name Revit assumes should be the next spool if the rule is set to run against new elements of type Assembly Instance. The Revit API does not allow changes to the name of the spool until the transaction that creates the spool has been committed. Once the spool is created, EVOLVE applies the name (specified by the user) to the spool. If the rule is set to run on Existing Element Change or Any Update, then the rule will be triggered to execute against the correct name. The Allow Multiple Processing option must be enabled or the rule will only execute on the name initially set by Revit.
