Is there a way to enable viewports (different scales on the same page)?

Hi Aaron. We don't have this yet. Our first step is to have "crop as new page" which we have working in our local development come out in our next release. This will at least give you the ability to select a box and make that operate as it's own page (with it's own scale). Allowing a viewport / scale box is something we've discussed. It would take more work than cropping, and there is a possibility that we will add at some point. This next update will at least give the ability to handle it as it's own page, which should help in the meantime.

This could be part of the "Links View" in my mind. Perhaps "wrap" around a detail, or anything else, and then scale that separately.

This was part of the idea behind Takeoffs On Overlays Instead of Pages. But I do like the “viewport” terminology.

Just so you are aware, the "Crop as New Page" is available in the latest version which is a good option for now to scale that new cropped page with a different scale.
