Topic: Storing notes in a dwg

[Mark]

I'm looking for some ideas. I want to store notes in a dwg that are not seen by everyone who opens the file. Perhaps xdata?

thanks

depends upon how why and what you want to do with it. It could be something as simple as text.visible=false
xdata's good though

I want something a little more than "text.visible=false" if possible. I realize I'll probably have to write an interface for it, what ever it is!

I want to mainly track changes and what not.

thanks hendie

I've been thinking of a similar thing for awhile, though it would be available to the user: a tree of notes that reside in dictionary type structure, with an appropriate interface to save, edit, delete, move ...

Anyway, not to derail you Mark ... consider using dictionaries (which sport higher capacities than xdata). If you need to have the data associated w/entites, link the entites to the dictinary by their xdata, otherwise the dictionar(s) can stand on their own.

Wanna "encrypt" it? I've got that string->binary representation progy. (It converts bothways.)

That sounds great!  I could defiantly benefit from something like this.

Oops, didn't mean to hijack this thread!

something like this?
 create new dictionary in collection using the Add method
 add a new XRecord to the dictionary using AddXRecord
 at this point I'm still reading ......

Yep, pretty much. Make sure you make the dictionary and it's entries are hard owned (dxf 280 or 281 I believe). That way they'll survive purges, wblocking etc.

xdata would be attached to an object and as such if the object were deleted the data would be lost, other options include ldata and dictionaries.

So it looks like a dictionary is the way to go from what I've read. Correct me if I'm wrong, but it appears you can store most anything in an XRecord, namely text.

Most anything yes, without the 16K xdata ceiling, as well as the ability to be entity agnostic.

Dicts are pretty easy to work with. Just don't take the authors advice to ENTMOD dictionary entries (he knows nothing).

thanks so much Stig, I knew should have looked over there.......... David Stein also has a bit about them in his book, so I've got some reading to do!
