Change 3d Graphics Visualization on multiple family files at once

[MLourdesYñigo]

I want to change the 3d backround of nearly a thousand family files basically, in order to upload them on Smart Family Browser whithout any backround and visualizing all of them the same way. Is there a why of batch changing this speciphic feature on all of them at once?

How do you do that now?  SAVE AS=>OPTIONS=>THUMBNAIL PREVIEW?

My goal is to do this on a thousand families at once.

So that's what you are talking about? Basically, a batch SAVEAS of 1000 Families?

I need all of them to look the same, as they all have different backrounds, and then, Family Browser gets the thumbnails for me according to the 3d view of each family. So the task would be, taking the background off, unifing the 3d visualization of the families, in batch

I am reading. I'm also asking questions trying to wrap my brain around what you need to batch process. You seemed to confirm that changing the Thumbnail Preview for each Family is what you want to do.  Is that correct?
