Parameters

ScaleFactor_x

Scaling factor in the x direction

ScaleFactor_y

Scaling factor in the y direction

ScaleFactor_z

Scaling factor in the z direction

IsUniform

True to use the first scale argument as the uniform scale, false to not

ScaleType

Type of scaling as defined in swCavityScaleType_e

KeepPieceIndex

Piece to keep if there is ambiguity

This operation is performed in the context of an assembly document. The component being edited in the context of the assembly receives the new cavity feature.

Set the scaleFactor argument as appropriate for your casting material. The scaling factor is expressed as a percentage (+/- 20%) of the size of the cavity part. Pass it in as a value within the range of -20 to +20.

SolidWorks uses the following formula to determine the size of the cavity:

cavitysize = partsize * (1 + scaleFactor/100)

When there is ambiguity in the result of a cut, SolidWorks uses KeepPieceIndex to determine which result to use. You can set this parameter to -1 if there is no ambiguity; otherwise, you should use the index of the result, in the range between 0 and 1 less than the possible number of outcomes.
