A method for maintaining links is described. A document selection is received, including a first destination document containing a first link to linked content. A first source document containing the linked content and not contained within the document selection is identified using the first link. A copy mode is selected, using an intrinsic property associated with the first link, from: a first mode where a second destination document that is a copy of the first destination document is generated and includes a second link to the linked content within the first source document, without copying the first source document, and a second copy mode where i) a second source document that is a copy of the first source document is generated, ii) the second destination document is generated and includes a second link to the linked content within the second source document. The selected copy mode is performed.

System and method for copying linked documents

A system, method, and computer program for organizing elements for compression, comprising nesting a hierarchical topological structure having a plurality of elements; arranging said plurality of elements in a pattern to facilitate data compression; representing said pattern as four arrays; and compressing said plurality of elements from said arrays, and appropriate means and computer-readable instructions.

Method and system for organizing topology elements for better compression

A system, method, and computer program for producing a visualization format from CAD data comprising producing a BREP model for visualization, wherein said BREP model has a topology component and a geometry component; removing a plurality of redundant control points from said geometry component; normalizing a plurality of knot vectors and a plurality of weight components from said geometry component; recognizing an analytic geometry from said geometry component; recognizing a plurality of equivalents from said geometry component; and converting said analytic geometry to said light model representation, and appropriate means and computer-readable instructions.

Visual file representation

A system, method, and computer program for tessellation. A method includes tessellating a curve having a plurality of polygons, connecting said plurality of polygons in a preferred direction, and decomposing polygons into a plurality of triangles. A mesh representation is created from the plurality of triangles.

System and method for trimmed surface tessellation

The size of lightweight JT data files containing CAD data is reduced by employing lossy compression where acceptable for portions of the CAD data, such as 3D geometry data. Dictionary-based lossless compression for the remaining portions is augmented by exploiting common repeated structures for some portions, such as precise Brep data, and compressing separate but similar data, such as all metadata for a given part and all scene graph data, together as a single block. The compressed data is then written in separate, uniquely identified data segments indexed in a table of contents, allowing quick access to any data segment for streaming.
