Raster Design 2011 - Merging and Exporting .sid files

[LeafRiders]

I new this couldn't be as easy as it seemed initially.

I merge 6 .sid files into one within Civil 3D / Raster Design 2011. Now the hard part... How do I export or save the image as a .sid file. I've tried the save as... option and the export option and no options are available except converting the .sid back to a tiff / junk.

Any help or insight would be appreciated. Please don't ask for computer specs because that isn't the problem here, haha.

I don't think you can export as a single sid file.

The information below was taken from Raster Design 2011.

That table shows that sid files are read only.
