Implementation of method "IsDeleted(...)" for MakeRevol and MakePrism algorithms. Problem (exception) occurs during history building and was caused by an attempt to obtain generated shape for subshape, which was really "deleted" by algorithm - this input subshape and its possible generated shape was not used in result.

//! Describes functions to build linear swept topologies, called prisms.
|
|
//! A prism is defined by:
|
|
//! - a basis shape, which is swept, and
|
|
//! - a sweeping direction, which is:
|
|
//! - a vector for finite prisms, or
|
|
//! - a direction for infinite or semi-infinite prisms.
|
|
//! The basis shape must not contain any solids.
|
|
//! The profile generates objects according to the following rules:
|
|
//! - Vertices generate Edges
|
|
//! - Edges generate Faces.
|
|
//! - Wires generate Shells.
|
|
//! - Faces generate Solids.
|
|
//! - Shells generate Composite Solids
|
|
//! A MakePrism object provides a framework for:
|
|
//! - defining the construction of a prism,
|
|
//! - implementing the construction algorithm, and
|
|
//! - consulting the result.
