std::Solid

A solid is a collection of extrude surfaces.

When you define a solid to a variable like:

myPart = startSketchOn('XY')
    |> startProfileAt([-12, 12], %)
    |> line(end = [24, 0])
    |> line(end = [0, -24])
    |> line(end = [-24, 0])
    |> close()
    |> extrude(length = 6)

The myPart variable will be an executed Solid object. Executed being past tense, because the engine has already executed the commands to create the solid.

The previous solid commands will never be executed again, in this case.

If you would like to encapsulate the commands to create the solid any time you call it, you can use a function.

fn createPart() {
   return startSketchOn('XY')
        |> startProfileAt([-12, 12], %)
        |> line(end = [24, 0])
        |> line(end = [0, -24])
        |> line(end = [-24, 0])
        |> close()
        |> extrude(length = 6)
}

Now, every time you call createPart(), the commands will be executed and a new solid will be created.

When you assign the result of createPart() to a variable (myPart = createPart()), you are assigning the executed solid to that variable. Meaning that the solid myPart will not be executed again.

You can still execute new commands on the solid like shell, fillet, chamfer, etc. and the solid will be updated.
