Value Type

Value

Specifies the maximum diffusion length, in user units, between two cut shapes and between a cut shape and a line-end of the diffusion shape.

Required Parameters

'width f_width

Specifies that the constraint applies only if the width of the diffusion shape is less than this value.

Examples

Requires that the distance between two Contact edges and a Contact edge and the nearest Diffusion line-end must be less than 0.2 if the width of the Diffusion shape is less than 0.05.
