# C.2.71 Selected shapes must define a rectangular area ...

The Import command (Button) on the Car Prototype dialog is used to create the image of an car from the shapes selected on the layout prior to opening the Car Prototype dialog. The car is assumed to be oriented horizontally so its length must be greater than its height. The selected shapes do not meet this requirement.

Refer to section 2.9.1.3 for detail.
