Example Site Variables

The maximum number of rays aPriori will use for ray-tracing based algorithms, such as accessibility/obstruction determinations. Increasing the value may result in better detection of very small obstructions, which could affect the decision of how a given feature is machined. However, this also will increase geometry extraction computation time. 

The maximum diameter for round stock (in millimeters). If the diameter of a round stock needed to enclose the part is larger than this value, a different stock form such as plate stock or rectangular stock will be selected instead. 

If true, aPriori will attempt to read a draw direction (mold opening direction) defined in the CAD model; if one is found, aPriori will use this direction rather than performing our own draw direction determination based on model geometry.

If true, GCD extraction will read the material-specific castability thresholds from the Digital Factory lookup tables. If false*, the static site variable values minCastableHoleWallThickness and minCastableHoleDiameter (see below) will be used.

If the CAD model includes a hole feature, but the wall thickness adjacent to that hole is less than the specified value, aPriori will assume that hole is not present in the raw casting, but machined subsequently. Raw material volume estimates will include the volume of material needed to “fill in” that hole.
