TsgDXFDimension
Unit: DXFConv
Description
This class defines special type for insert a linear dimension measuring. A linear dimension measuring the distance between two points which is displayed parallel to the points being measured. In aligned dimensions, the dimension line is parallel to the extension line origins.
Syntax
TsgDXFDimension = class(TsgDXFInsert)
