## Example

```go

package main

import (

	"github.com/edanko/dxf"

	"github.com/edanko/dxf/color"

	"github.com/edanko/dxf/table"

	"log"

	"math"

)

func main() {

	d := dxf.NewDrawing()

	d.Header().LtScale = 100.0

	d.AddLayer("Toroidal", dxf.DefaultColor, dxf.DefaultLineType, true)

	d.AddLayer("Poloidal", color.Red, table.LT_HIDDEN, true)

	z := 0.0

	r1 := 200.0

	r2 := 500.0

	ndiv := 16

	dtheta := 2.0 * math.Pi / float64(ndiv)

	theta := 0.0

	for i := 0; i < ndiv; i++ {

		d.ChangeLayer("Toroidal")

		d.Circle(0.0, 0.0, z+r1*math.Cos(theta), r2-r1*math.Sin(theta))

		d.ChangeLayer("Poloidal")

		c, _ := d.Circle(r2*math.Cos(theta), r2*math.Sin(theta), 0.0, r1)

		dxf.SetExtrusion(c, []float64{-1.0 * math.Sin(theta), math.Cos(theta), 0.0})

		theta += dtheta

	}

	err := d.SaveAs("torus.dxf")

	if err != nil {

		log.Fatal(err)

	}

}
