Hi! Yes! That's exactly what I mean. To help with context - I have a 100-mile alignment that changes quite often and involves 270 plan sheets at 100 scale. I am receiving surface data from a third party (think of it as tiles). Every time there is an alignment change I have to piece-mail the data together - and then post process it to reduce the size. The resulting surfaces are large enough in files size that it's cumbersome. I would like to have a surface that isn't cropped, so if the alignment changes again, I can keep changing the cropped surface on the fly and keep the surface file size low. But since a cropped surface looks for a source drawing - I feel like I'm not gaining anything even if the cropped surface resorts in a small file size, but it has to look for two source drawings, one for the data shortcut and one for the cropped surface. Hopefully, this makes sense. I am about to embark on creating these and was hoping someone may have some experience/wisdom in this area. Thank you for your reply!
