Use the forum search facility, it's been discussed a couple of times.

...by yourself in at least one case. Sorry, I should have followed through the context more.

LibreDWG, according to my observations, is managed with non-complex files. I managed to read the file and iterate through all the objects in it. I haven't tried write dwg yet. There is a difficulty in translating headers - macros are actively used

I dont need all library of LibreDWG, I need it only for points, assume there is a point includes X,Y,Z and I want to create a simple dwg for the coordinate via lazarus.

Unfortunately, everything has been done in dwg to complicate it third-party use.
You can write the reading yourself by spending a lot of effort. I tried, it's hopeless. Only use ready-made tools with their problems and limitations((
