Ellipse walls in ADT

Here's a way to create ellipse walls in ADT.

• Type PELLIPSE and set the value to 1.
• Draw an ellipse with the values needed.
• Right click any wall tool on a tool palette and choose Apply tool properties too... -> Linework.
• Select the ellipse and you will have a wall that is segmented, but in the shape of an ellipse.

The reason this works is it generates the ellipse as an approximation (a rather good one) and generates it as a segmented polyine.
