Micromanaging Xrefs?

[deltacoolguy]

Kind of a generic question, and I doubt there's a satisfactory answer for me, but I'll give it a shot.

I have an existing topo file with an aerial photo attached (image file: tiff).  The aerial photo has a legitimate purpose for being there, and I do not feel right in detaching it.  It is needed for some files down the line, but not all.

I also have a plan & profile drawing that has said existing topo file xref'd into it as an overlay.  I need the existing topo line work, but I don't want the aerial photo.

I know that I can freeze the layer that the aerial photo is on, and I do that, but is there a way to xref a file and it be only that file, not everything else tagging along?

I also know that I could reference the aerial photo images separately and only in the needed drawings, which would be my preference, but others in my company frown on that.

Block the aerial out to it's own file an Xref it into the design and/or sheet files that need it. If you load the image in files that do not need it you are needlessly consuming system resources that C3D needs. Alos if it's in your file as an xref you can simply unload it if it's not needed VS messing around with layers, layer states and layer filters.

IMO this should be SOP in all firms.

I just put imagery into it's own dwg with nothing else and the XREF this as required which as John Mayo suggests reduces unneccesary file bloat.

Create a new layer XREF_IMAGE_XXX, make it current and then xref the image. You can then control the image with freeze and thaw commands then instead of load and unload.
