CAD Weight Reduction

Users of Process Plant and Ship Building design software frequently need to integrate models of large equipment installations and component sub-systems. These usually consist of very large CAD assemblies that can be several hundred Megabytes or even Gigabytes in size. The receiving systems are simply not designed to cope with the integration of such massive CAD assemblies. The main priority of the ship building or process plant designer is simply to reduce file size.

CADfix can quickly simplify large complex CAD assemblies and reduce file size for import into Process Plant and Ship Building software. This helps avoid multiple failed import attempts, saves precious project time and reduces non-productive CAD model rework. Most of these processes can be done in automatic. The CADfix simplification tool will leave enough detail to accurately represent the equipment structure and outer envelope, whilst removing unwanted intricate detail and reducing file size.

The CADfix simplification tools can be run in an automated batch process or with manual user interaction. General operations can be run in the automated environment, with manual interaction when the user requires greater control of the layout. Typical CADfix model simplification operations include:
 
  • Automatic remove small parts based on bounding box size
  • Automatic remove parts of similar shape and size to a selected item
  • Automatic remove internal detail
  • Simplify complex parts to minimum volume bounding boxes or cylinders
  • Remove holes, protrusions and internal cavities
  • Remove design features such as fillets, rounds and chamfers
  • Collapse or join entities such as short edges, narrow faces etc
  • Join faces or bodies
  • Delete user-selected entities
  • Simplify NURBS edges and surfaces to analytic forms or reduce NURBS complexity
  • Convert geometry to simplified lightweight forms

 

External Visibility Filter with CADfix

During simulation preparation, it could be necessary to remove hidden or internal details from a CAD model. The External Visibility Filter is a new CADfix Wizard Transform tool that scans the model, identifies externally visible faces or bodies an removes the unwanted internal details. You can control the structure level (instances, bodies, faces) and the gap tolerance. Even if the assembly is disjuncted with small gaps, the internal parts will be removed.

Minimum volume bounding box with CADfix

The minimum or smallest bounding or enclosing box is a term used in geometry. It refers to the box with the smallest measure (area, volume, ...) within which all the geometry lie.
