Descripción
El FiltroCompuesto puede utilizarse para extraer las piezas individuales del resultado de, por ejemplo, una Pieza Rebanada operación , con la que se ha dividido un objeto.
Puede extraer a los niños por sus índices, probar a los niños por colisiones con la forma de la plantilla, y filtrar a los niños en base a sus propiedades, como la longitud, el área, el volumen.
Si sólo hay un niño en el resultado, la salida es el niño. Si hay más de un hijo en la salida, la salida es un nuevo compuesto.
Utilización
- Select the sliced object
- There are several ways to invoke the command:
- Press the
Compound Filter button. - Select the Part → Compound → Compound Filter option from the menu.
- Press the
- Select the CompoundFilter Object in the Tree View.
- In the properties tab set "Filter Type" to "specific items".
- Set items to the elements you want to extract:
- For a single piece this is a number starting with 0, i.e. if you want to extract the first element enter 0 in this field, 1 for the next element …
- If you want to extract more than one piece at a time separate the numbers with ";", e.g. a value of "0;2" will extract the first and the third element.
- The general case - which covers the possibilities mentioned above as well - is a list of index ranges, specified in Python notation, but without brackets. Ranges can be chained with semicolon. For example:
- 7:10 take children of indexes 7, 8 and 9 (indexes are zero-based; range-to index is excluded).
- 1;2 take children 1 and 2 (first range is child 1, second range is child 2, ranges joined by semicolon).
- 0;-1 take first children (index 0) and last one (index -1 means last child, -2 - one but last, and so on).
- 1: take all but first child (missing index means "all the way to the end").
- ::-1 take all children in reversed order.
- ::2 take all odd-indexed children, i.e. indexes, 1,3,5,…, which are the elments 2,4,6, …
- :;: repeat the input compound twice.
- If you want to extract another piece select the sliced object again. It is now placed under the CompoundFilter in the Tree View.
- Repeat the selection procedure from above. The slice and its subelements will be displayed under both CompoundFilters; they are, of course not repeated in the model. A very fast way to extract another piece is to copy the CompoundFilter. But watch out: You are asked if you want to copy the elements under the CompoundFilter too, which you must answer with no, you don't want to copy them, you only reference them.
Propiedades
- DatosBase: Object to be filtered.
- DatosFilter Type selectable options:
- bypass: no filter. The original compound is output, unchanged.
- specific items: extract the items listed in the "items" property
- collision-pass: extract pieces that touch or intersect with 'Stencil' shape.
- window-volume (default): extract all pieces which have a volume between "Window From" and "Window To" where 100% is the biggest piece - and not the unsliced object. The value of 100% is a reference value which can be overridden by "OverrideMaxVal".
- window-area: the same as window-volume where the sliced area determines the selection instead of the volume.
- window-length: the same as window-volume where the length of the edges determines the selection instead of the volume.
- window-distance: extract children whose distance to 'Stencil' shape is within value window, defined by properties "Window From", "Window To", "Override Max Val".
- DatosInvert: If set to true the list as described above is excluded instead of included.
- DatosOverride Max Val: Value window range is defined in percentages of maximum value. The maximum value is computed according to the following set of rules:
- if 'OverrideMaxVal' is nonzero - use it.
- otherwise, if 'Stencil' link is supplied - calculate the corresponding value of stencil shape (not applicable to window-distance 'FilterType')
- otherwise, take maximum value from children in compound to be filtered.
- DatosStencil: Link to a stencil shape. For collision-pass and window-distance FilterType's, stencil is the object to test collision/distance against. For other "window-***" filter types, stencil is used to provide reference value for window percentages (maximum value override). In all other modes, 'Stencil' is ignored.
- DatosWindow From: Upper threshold percentage for selecting pieces, 100% is relative to the biggest piece.
- DatosWindow To: Lower threshold percentage for selecting pieces, 100% is relative to the biggest piece.
- Datositems: List or range of elements to be selected if Filter Type is "specific items".
