Manual Overlays General FAQ

Is it easy to use?

Non technical persons are able to understand and use the manual versions of ShadowDraw - this is what has made it so enduring over the past 20 years. The AutoCAD versions require only a very basic understanding of AutoCAD.

How soon will the kit be delivered?

We try to turn around orders the same day. Delivery is by Australia Post ordinary mail and included in the price. An Express Post Envelope can be sent for an additional $6 - ring or advise on the order.

Can it make allowance for sloping land? Can it show shadows on a wall, or in section or elevation view?

The answer to both questions is "yes", but they require a second level of analysis by the operator after the shadow is shown on plan, on a theoretical 'flat' plane.

There are instructions in the kit.

How do I know if it is the eaves or roof ridge that are causing the shadow?

By testing the extent of shadow cast by each element of a building. Sometimes it is easier to understand a complicated design as being a series of 'flagpoles'. By testing which features have the longest shadow the 'real' shadow cast by the building is revealed.
