26 | |
27 | ---Purpose: Describes functions to build draft |
28 | -- prism topologies from basis shape surfaces. These can be depressions or protrusions. |
29 | -- The semantics of draft prism feature creation is based on the |
30 | -- construction of shapes: |
31 | -- - along a length |
32 | -- - up to a limiting face |
33 | -- - from a limiting face to a height. |
34 | -- The shape defining construction of the draft prism feature can be |
35 | -- either the supporting edge or the concerned area of a face. |
36 | -- In case of the supporting edge, this contour can be attached to a |
37 | -- face of the basis shape by binding. When the contour is bound to this |
38 | -- face, the information that the contour will slide on the face |
39 | -- becomes available to the relevant class methods. |
40 | -- In case of the concerned area of a face, you could, for example, cut |
41 | -- it out and move it to a different height which will define the |
42 | -- limiting face of a protrusion or depression. |

68 | ---Purpose: A face Pbase is selected in the shape |

71 | -- - removing matter with a Boolean cut using the setting 0 |
72 | -- - adding matter with Boolean fusion using the setting 1. |
73 | -- The sketch face Skface serves to determine the type of |
