## Tagged Operations
|
||||
BOSL2 introduces the concept of tags. Tags are names that can be given to attachables, so that
|
||||
you can refer to them when performing `diff()`, `intersect()`, and `conv_hull()` operations.
|
||||
Each object can have no more than one tag at a time.
|
||||
|
||||
### `diff(remove, <keep>)`
|
||||
### `diff([remove], [keep])`
|
||||
The `diff()` operator is used to difference away all shapes marked with the tag(s) given to
|
||||
`remove=`, from the other shapes.
|
||||
`remove`, from the other shapes.
|
||||
|
||||
For example, to difference away a child cylinder from the middle of a parent cube, you can
|
||||
do this:

@ -445,7 +446,7 @@ tag("keep")cube(100, center=true)

```
|
||||
|
||||
|
||||
If you need to mark multiple children with a tag, you can use the `tag()` module.
|
||||
You can of course apply `tag()` to several children.

||||

```
|
||||
|
||||
Many of the modules that use tags have default values for their tags. For diff the default
|
||||
remove tag is "remove" and the default keep tag is "keep". In this example we rely on the
|
||||
default values:
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
diff()
|
||||
sphere(d=100) {
|
||||
tag("keep")xcyl(d=40, l=120);
|
||||
tag("remove")cuboid([40,120,100]);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
The parent object can be differenced away from other shapes. Tags are inherited by children,
|
||||
though, so you will need to set the tags of the children as well as the parent.
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
diff("hole")
|
||||
cube([20,11,45], center=true, $tag="hole")

||||

|
||||
tag("body")cube([40,10,90], center=true);
|
||||
```
|
||||
|
||||
Tags (and therefore tag-based operations like `diff()`) only work correctly with attachable

### `intersect(a, <b>, <keep>)`
|
||||
### `intersect([intersect], [keep])`
|
||||
|
||||
To perform an intersection of attachables, you can use the `intersect()` module. If given one
|
||||
argument to `a=`, the parent and all children *not* tagged with that will be intersected by
|
||||
everything that *is* tagged with it.
|
||||
To perform an intersection of attachables, you can use the `intersect()` module. This is
|
||||
specifically intended to address the situation where you want intersections involving a parent
|
||||
and a child, something that is impossible with the native `intersection()` module. This module
|
||||
treats the children in three groups: objects matching the `intersect` tags, objects matching
|
||||
the tags listed in `keep` and the remaining objects that don't match any listed tags. The
|
||||
intersection is computed between the union of the `intersect` tagged objects and the union of
|
||||
the objects that don't match any listed tags. Finally the objects lsited in `keep` are union
|
||||
ed with the result.
|
||||
|
||||
In this example the parent is intersected with a conical bounding shape.
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
intersect("bounds")
|
||||
cube(100, center=true)
|
||||
cylinder(h=100, d1=120, d2=95, center=true, $fn=72, $tag="bounds");
|
||||
tag("bounds") cylinder(h=100, d1=120, d2=95, center=true, $fn=72);
|
||||
```
|
||||
|
||||
If given both the `a=` and `b=` arguments, then shapes marked with tags given to `a=` will be
|
||||
intersected with shapes marked with tags given to `b=`, then unioned with all other shapes.
|
||||
In this example the child objects are intersected with the bounding box parent.
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
intersect("pole", "cap")
|
||||
intersect("pole cap")
|
||||
cube(100, center=true)
|
||||
attach([TOP,RIGHT]) {
|
||||
cube([40,40,80],center=true, $tag="pole");
|
||||
sphere(d=40*sqrt(2), $tag="cap");
|
||||
tag("pole")cube([40,40,80],center=true);
|
||||
tag("cap")sphere(d=40*sqrt(2));
|
||||
}
|
||||
```
|
||||
|
||||
If the `keep=` argument is given, anything marked with tags passed to it will be unioned with
|
||||
the result of the union:
|
||||
The default `intersect` tag is "intersect" and the default `keep` tag is "keep". Here is an
|
||||
example where "keep" is used to keep the pole from being removed by the intersection.
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
intersect("bounds", keep="pole")
|
||||
intersect()
|
||||
cube(100, center=true) {
|
||||
cylinder(h=100, d1=120, d2=95, center=true, $fn=72, $tag="bounds");
|
||||
zrot(45) xcyl(h=140, d=20, $fn=36, $tag="pole");
|
||||
tag("intersect")cylinder(h=100, d1=120, d2=95, center=true, $fn=72);
|
||||
tag("keep")zrot(45) xcyl(h=140, d=20, $fn=36);
|
||||
}
|
||||
```
|
||||
|
||||
### `conv_hull(keep)`
|
||||
You can use the `conv_hull()` module to hull shapes together the
|
||||
shapes not marked with the keep tags, before unioning the keep shapes
|
||||
into the final result.
|
||||
### `conv_hull([keep])`
|
||||
You can use the `conv_hull()` module to hull shapes together. Objects
|
||||
marked with the keep tags are excluded from the hull and unioned into the final result.
|
||||
The default keep tag is "keep".
|
||||
|
||||
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
conv_hull("pole")
|
||||
cube(50, center=true, $tag="hull") {
|
||||
conv_hull()
|
||||
cube(50, center=true) {
|
||||
cyl(h=100, d=20);
|
||||
xcyl(h=100, d=20, $tag="pole");

If you need to distribute copies along an arbitrary line, you can use the
|
||||
`line_of()` command. You can give both the direction vector and the spacing
|
||||
`line_copies()` command. You can give both the direction vector and the spacing
|
||||
of the line of copies with the `spacing=` argument:
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
line_of(spacing=(BACK+RIGHT)*20, n=5) sphere(d=10);
|
||||
line_copies(spacing=(BACK+RIGHT)*20, n=5) sphere(d=10);
|
||||
```
|
||||
|
||||
With the `p1=` argument, you can specify the starting point of the line:
|
||||
```openscad-3D
|
||||
include <BOSL2/std.scad>
|
||||
line_of(spacing=(BACK+RIGHT)*20, n=5, p1=[0,0,0]) sphere(d=10);
|
||||
line_copies(spacing=(BACK+RIGHT)*20, n=5, p1=[0,0,0]) sphere(d=10);
|
||||
```
|
||||
|
||||
If you give both `p1=` and `p2=`, you can nail down both the start and
|
||||
endpoints of the line of copies:
|
||||
```openscad-2D
|
||||
include <BOSL2/std.scad>
|
||||
line_of(p1=[0,100,0], p2=[100,0,0], n=4)
|
||||
line_copies(p1=[0,100,0], p2=[100,0,0], n=4)
|
||||
sphere(d=10);
|
||||
