APT Feature Representation

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

APT features consist of geometry and attributes. The attribute names are defined in the DEF line and there is a value for each attribute in each APT feature.

The table below lists the attributes contained in all APT features.

Attribute Name

Contents

apt_type

The APT geometric type of this entity.

Range: apt_point|apt_none

apt_ival

This is the i coordinate to the point that is in normal vector.

Range: Floating Point Number

Default: Blank

apt_jval

This is the j coordinate to the point that is in normal vector.

Range: Floating Point Number

apt_kval

This is the k coordinate to the point that is in normal vector.

Range: Floating Point Number

Points

apt_type:apt_point

APT point features specify a single x and y coordinate in addition to any associated user-defined attributes.

There are no special FME attributes for the APT point type. Currently, only point features are supported.
