Measurements

Area and length measurements

Certain entities support calculation of area and length (perimeter): CIRCLE, ELLIPSE, ARC and LWPOLYLINE. Additionally, POLYLINE entity supports calculation of length but not the area. Other entities throw NotImplementedException.

Here is the example how to calculate length and area:

CadImage cadImage = (CadImage)Image.load(sourceFilePath);  for (CadEntityBase cadEntityBase : cadImage.getEntities()) { try { System.out.println(cadEntityBase.getTypeName() + " " + cadEntityBase.getArea() + " " + cadEntityBase.getLength()); } catch (NotImplementedException ex) { ... } }
