What Is a Variant?
Use Variants in Methods and Properties
Convert Arrays to Variants
Variants are used to pass array data in and out of AutoCAD ActiveX Automation. This means that your array must be a variant to be accepted by AutoCAD ActiveX Automation methods and properties. In addition, array data output from AutoCAD ActiveX Automation must be handled as a variant.
NoteIn AutoCAD,
VBA input arrays are automatically converted to variants. This means
that you don't have to provide a variant array as input to the ActiveX Automation
methods and properties when using them from VBA. However, all the
output arrays will be in the form of variants, so remember to handle
them appropriately.
