Adding Meters and Pixels

I currently have a system that's drawing rings, with the radius set in meters:

```

Draw.ThicknessSpace = ThicknessSpace.Noots;
Draw.Thickness = RingThickness;
Draw.DiscGeometry = DiscGeometry.Flat2D;
Draw.RadiusSpace = ThicknessSpace.Meters;

Draw.Radius = RingRadius;

Draw.Ring();

```

However, I want to make this ring look a little fancier by drawing some more rings nearby. For example a solid ring sandwiched by 2 dashed rings.

Ideally, I want the sandwiching rings to be offset by the width of the initial ring. For example:

```

Draw.Radius = Meters(RingRadius) + Noots(RingThickness);

Draw.Ring();

Draw.Radius = Meters(RingRadius) - Noots(RingThickness);

Draw.Ring();

```

tl;dr: I want to mix units.

Is there some way to achieve something like this?
