These constants define common entity attributes. By default, an entity does not have any attributes. An attribute is created when the entity method get_AttribPtr is called. This function returns a pointer to the corresponding attribute.
| IG_VECT_ENT_ATTR_DRAWCOLOR | The attribute is a draw color. get_AttribPtr returns a pointer to IGVectColorEx. |
| IG_VECT_ENT_ATTR_FILLCOLOR | The attribute is a fill color. get_AttribPtr returns a pointer to IGVectColorEx. |
| IG_VECT_ENT_ATTR_LINETYPEINDEX | The attribute is a line type index. get_AttribPtr returns a pointer to long. |
| IG_VECT_ENT_ATTR_THICKNESS | An attribute is a line thickness. get_AttribPtr returns a pointer to float. |
| IG_VECT_ENT_ATTR_FILLTYPEINDEX | An attribute is a fill type index. get_AttribPtr returns a pointer to long. |
| IG_VECT_ENT_ATTR_OFFSET | An attribute is an entity offset. get_AttribPtr returns a pointer to IGVectPoint3D. |
| IG_VECT_ENT_ATTR_ROTATION | An attribute is an entity rotation. get_AttribPtr returns a pointer to IIGVectRotation. |
| IG_VECT_ENT_ATTR_SCALE | An attribute is an entity scale factors. get_AttribPtr returns a pointer to IGVectPoint3D. |
| IG_VECT_ENT_ATTR_POSITION | An attribute is a position of an entity inside the block. get_AttribPtr returns a pointer to IGVectPoint3D. |
