DIMENSION –surface descriptions at your fingertips

Reducing the process loops inreverse engineering is essential if you want to maintain your compe- titive edge. To achieve this, proto- types are needed immediately in the form of actual models and CAD data. DIMENSION permits surface descriptions to be produc- ed from digitized models or partly digitized areas of modification in the easiest way possible. The result is a finished design.

The CAD designer gets the finished design as adata record for direct use in his existing environment. The engineering work required for this purpose is per-formed by DIMENSION – an advantage from whichtool manufacture also benefits.CAD data can also be used directly in CAD/CAM systems for the computation of NC programs.

Computed surfaces instead of random point clouds

Intelligent algorithms in DIMENSION generateultra-precise surface descriptions and curves from ran- dom point clouds.These are transferred as NURBS.Complex surfaces can therefore be described by a fewsegments and with small data quantities.Unlike in conventional methods,standard geometries are not described by approximations but by exact geometric elements.In addition to providing the actual modeldescription,the algorithms smooth the surfaces to such an extent that transitions with virtually constanttangents and curvatures are obtained – a prerequisite for optimum cutting paths without the need for manual correction during production.
