Envelope components selected in the feature manager tree
Envelope components selected in the feature manager tree

This macro is using SOLIDWORKS API to extend the available list of selection criteria in the Advanced Selection tool in SOLIDWORKS assembly.

Macro allows to select the following group of components (or combinations)

  • Float - underconstrained components (components which have minus symbol (-) in their names)
  • ExcludedFromBom - components which are excluded from Bill Of Materials (including Envelope components)
  • Envelope - components which are marked as envelope
  • NoMates - components which contain no mates

In order to configure the macro modify the CRITERIA and TOP_LEVEL_ONLY constants in the beginning of the macro.

Const CRITERIA As Integer = Criteria_e.Float + Criteria_e.NoMates
Const TOP_LEVEL_ONLY As Boolean = False

TOP_LEVEL_ONLY indicates if only top level components should be used for filtering. Set this option to True to select nested components as well

Const TOP_LEVEL_ONLY As Boolean = True

CRITERIA is a combination of filters where Or operator is applied.

For example

Const CRITERIA As Integer = Criteria_e.Float + Criteria_e.NoMates 'All float components or components with no mates wil be selected
Const CRITERIA As Integer = Criteria_e.Envelope 'Only envelope components will be selected

Modify the filter in the macro as required.

Enum Criteria_e
    Float = 1
    ExcludedFromBom = 2
    Envelope = 4
    NoMates = 8
End Enum

Const CRITERIA As Integer = Criteria_e.Float + Criteria_e.NoMates
Const TOP_LEVEL_ONLY As Boolean = False
