Thumbnail Preview from memory

[sresh]

Should create dwg in side database and then display in preview even before saving the dwg.

I want to create a drawing in memory and then display it as preview, to show the user how the dwg would look. Is it possible?

More information is needed.

Please clarify what you mean by 'create a drawing in memory' - within a Transaction using MdiActiveDocument.Database, or using ReadDwgFile() (aka side-database)?

Display it (the calculated geometry, and resultant entities) how - as transient graphics on-screen for user (think jig, or cursor badge, etc.), or as an actual thumbnail as part of a WPF Window/Form instance?

Cheers

Thanks for the post.

I intend to have a side database, do some modifications in the file, then show that as preview before the drawing is displayed in the active window. However, I now understand that a Thumbnail is created only if a file is opened and save, be it dwg or image. So is there any other option?

Thanks
