Continuing the discussion from Components VS Group : In the above referenced thread, @DaveR , @slbaumgartner and I have each created similar variations of a single piece of grouped (via both Group and Component) geometry and arrags of each variation - then compared the resulting file sizes - with sig…

[image] sjdorst: Is it documented anywhere? No. It is proprietary and has never been documented publicly.

While the file format is proprietary, the C API could give an inkling for how the file is organized. (The intro page contains a file read example.) I wonder if a program is already available to dump a *.skp file in a textual format, be it plaintext or structured, e.g. YAML.

[image] jim_foltz: [image] Michael_S: … dump a *.skp file in a textual format … For what purpose? I think it could be useful to, e.g., verify contributions to sombeody’s library :wink: or, as @sjdorst asked, inspect group and DC attributes. If you meant specifically the YAML aspect, I …

[image] Michael_S: While the file format is proprietary, the C API could give an inkling for how the file is organized. (The intro page contains a file read example.) I would quibble that the C SDK can provide valuable information about what the model contains and how the model is organized, …

[image] jim_foltz: For what purpose? For myself, I’m interested in understanding the file size differences between the 7 files I created as an experiment in the Components VS Group post from which I started (by replying as new topic) this topic. My interest is, for the most part, simple curi…

[image] Michael_S: To address the original request, can your code show the model entities’ attributes yet (short of entire geometry) and would you be able to share it? Yes and yes, including all geometry - I planned on putting online but just haven’t got around to it yet. I’ll let you know w…

[image] sjdorst: As there are (I think) non-Trimble programs that can read .skp files, I assume that such documentation exists, Why? They could read .skp files using the C SDK without documentation of the file format.

As I have no interest in doing this, I actually don’t know! That’s why I included “(I think)” and “assume” in my post! It wouldn’t surprise me if a 3rd party developer, having tried to do what they need using the C SDK, find that it wasn’t sufficient and managed to negotiate (with Trimble) access to…

Can you distill that thread into a brief overview? What you observe and what you expected?

Is there any documentation of the .skp file format?
