Controlling the Representation of Holes

Holes may be represented realistically, with colour shaded inner surfaces, and may be ‘seen through’.

1. To control the appearance of holes, run the following commands:

   EXPORTHOLEs ON
   HOLEs OFF(default)
   HOLEs SOLID

   EXPORT HOLES SOLID represents holes as solids in colour 1, which by default is black. Solid holes cannot be seen through.

2. To query the state of the hole settings, run the following command:

   Q EXPORT HOLES

   Notes: Since holes are constructed using facets which involve a large amount of geometric data, switching holes ‘on’ will increase the computational overhead when processing. The more holes in the model, the longer the model file will take to generate, and the more slowly it will be drawn in Review.
   
   Other representation settings, such as Tube, Centreline, Obstruction, Insulation and Drawing Level, are taken from the current Design settings.
