Unit and Scaling Factor

[chan]

Hi, I would like to know the unit and scaling factor used in a particular dxf file. For example, a floor plan may indicate
1 meter :100 meter, which means 1 meter in drawing is equavalent to 100 meter in real world. Does this information stated in dxf file?

By the way, what is the meaning of Absolute Height and Absolute Width in class CADImage? What is the unit of these 2 members?(e.g meter, milimeter or inch...)

Thank you

Hello!

Units in the DXF file are just units. They are not millimeters, not inches etc. They are just units. On other side is they may be interpreted by different ways.

<b>CADImage.AbsWidth</b> and <b>CADImage.AbsHeight</b> are absolute values of height and width of the drawing. It means that a drawing may have points with negative coordinates. Such points can't be used in some special operations. Thus <b>CADImage.AbsWidth</b> and <b>CADImage.AbsHeight</b> are used.

If necessary, please send us some of your files for an additional tests. Please make a reference to this topic.
