# Operaciones booleanas geométricas

Los métodos *Intersect*, *Trim* y *SelectTrim* se utilizan principalmente en geometrías dimensionales inferiores como puntos, curvas y superficies. Por otra parte, la geometría sólida cuenta con un conjunto adicional de métodos para modificar la forma después de su creación, tanto sustrayendo material de forma similar a *Trim* como combinando elementos para formar un todo mayor.

### Unión

El método *Union* utiliza dos objetos sólidos para crear un único objeto sólido a partir del espacio cubierto por ambos objetos. El espacio solapado entre los objetos se combina en la forma final. Este ejemplo combina una esfera y un cubo en una forma de esfera-cubo sólida:

![](/files/6oaDVz0jFZCqx8msHG4O)

```js
s1 = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin, 6);

s2 = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin.Translate(4, 0,
    0), 6);

combined = s1.Union(s2);
```

### Diferencia

El método *Difference*, al igual que *Trim*, resta el contenido del sólido de la herramienta de entrada del sólido base. En este ejemplo, se extrae una pequeña hendidura de una esfera:

![](/files/FKRvIdmCHlQ5DjYq5nUn)

```js
s = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin, 6);

tool = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin.Translate(10, 0,
    0), 6);

result = s.Difference(tool);
```

### Intersecar

El método *Intersect* devuelve el sólido solapado entre dos entradas sólidas. En el siguiente ejemplo, *Difference* se ha cambiado a *Intersect* y el sólido resultante es el vacío que falta que se ha eliminado inicialmente:

![](/files/SmzQjAxX2PDk6iOFIIAY)

```js
s = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin, 6);

tool = Sphere.ByCenterPointRadius(
    CoordinateSystem.Identity().Origin.Translate(10, 0,
    0), 6);

result = s.Intersect(tool);
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://primer2.dynamobim.org/es/8_coding_in_dynamo/8-2_geometry-with-design-script/9-geometric-booleans.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
