Layer status

Hello guys ,

When trying to extract layer table and to check if the DXF 70 for the status of a layer , I have noticed that I have number five like this (70 . 5) which means that the layer is freezed and locked ( this is because I know the status of the layer) .

This is one status that I have noticed recently , Anyone knows what are the different DXF return value that we may also face and what does it mean?

Thanxxxxxx

Thankx Lee , that's what I am refering to , I would like to know how many return values that we may see which is not included within the DXf code the same like 5 or maybe 6 or 7 and so on .

Since DXF 70 is bit-coded, the values are combined using addition.

Hence

5 = 4 + 1

6 = 4 + 2

7 = 4 + 2 + 1

Since the highest available bit for DXF 70 is 64 (2^6), there are 127 ([2^7]-1) possible values, and 128 including 0.

What do you mean by bit-coded ?
