Hello
I am simply trying to create a duplicate (.tif) image in my drawing using the COPY REFERENCE icon in the REFERENCES dialog box. Unfortunately, the copy does not have the colors inverted (like the original does) and is showing in reverse b/w color. Is this caused by a setting or a default instruction?

Because the reference manager does not handle raster images correctly. You need to use the right tool for the job. If you continue using the reference manager rather than the raster manager you may never achieve the desired results.

I understand. Maybe it's a good time to do it the right way. I don't suppose you would be kind enough to point me to the help section for masking parts of a raster would you please? Or should i simply place blank polygons over the bits i don't want to show and then set the priorities to ensure the overdrawn bits show correctly? Which option would give the best results?
Raster Manager has a similar set of tools to the reference tools, however, they are optimized for use with raster files. They include tools to clip and mask raster references. You can find all of those tools in the raster manager dialog after you have attached your image properly as a raster.
The regular reference file tools are optimized to work with vector (CAD) data. While it is technically possible to attach a raster through the regular reference tools, they aren't programmed for that, and you will often get unexpected results - such as you are experiencing now. If you use the correct tools, you should get more reliable results

Hi Andy,
I still do not understand the workflow you are following. Once you have attached the rasters using the raster dialog, are you trying to copy the image on the same file again multiple times? As far as I know the raster manager dialog does not have option to copy raster as in the reference dialog. This option is avaliable in other product as Descartes or mapping products. See https://youtu.be/-cQBRlMkbb8
Could it be ok to attach the tiff image several times on the same drawing to duplicate it using the Raster Manager?
Regarding masking and clipping rasters you could review the following content

There are couple ways to handle this. As you stated, you can create shapes over the areas to clip and use a background fill color to hide the areas you don't need.
What I like to do is have the raster file attached to its own .dgn file. Then you can use reference manager to attach that dgn file to another dgn. This allows you to use the standard reference manipulation tools for clipping. This method makes changes to the clipped areas easier to handle.
One other option is to attach the raster to your current file. Place it on an independent level. Now you can attach your current file to itself. In the active file, turn off the level for the raster image. Make sure the level is turned on in the self reference and now you can use the reference manager modification tools to clip the self reference.
All depends on what you are comfortable doing.
