Hi
You are better to use our new layers functionality rather than the older vector objects. Layers support vector lines and shapes, as well as text and images.

There are demos for this in the Demos\LayerEditing\ folder.
You can import from DXF and export to SVG or PDF.
Loading and saving is support in our native IEN format.
Naturally, all layers can be iterated and their properties read and set, e.g.
ImageEnView1.Layers[3].FillColor := clRed; // Generic access to fill property
TIELineLayer( ImageEnView1.Layers[3] ).LineLength := 100; // Access to properties of line layers
