I just wanted to point out that it is technically possible to read the data without checking for errors.
If doing so is good style, careless or what ever is another question.

Personally I think the RS encoding is not there to obfuscate the format but to ensure that all
data gets transferred correctly. In later formats (2010/2013) it is missing again, for whatever reason

first target was to read through the drawing.

Here is another link from the spec:

Hi Till,

So is it not really necessary to use RS decoding at all?

I must admit that I really don't see any need for error checking in a
drawing file and I had assumed that this was a ruse by Autodesk to
obfuscate the dwg format.
