Hi,

Within the DXF you find data how objects are created, not the properties from calculations.

You'll have to do your calculations by yourself of by loading the DXF-file into a software that knows the object an can do the calculations for you.

Hi,

>> please provide any hint to calculate the length of object

Which object type(s)?, this can be a simple line, curved or splined (2d)polyline, 3d-spline, up to application specific proxy objects ...

Hi,

sorry, please don't wait for results from my side ... I would have to use Google-search for geometry calculation sites too.

And I would estimate differences in when calculating splines as there are some different calculation methods depening on the parametrization.

Good luck, - alfred -
