As noted by @Anonymous.Fuhrman working with point clouds can involve very large files. Save the consolidated file for general reviews, ensure you can break it down into smaller logical chunks for design work. No point loading the entire point cloud when you're only working on a single building at a time.
While there are some *really* cool things out there for automagically converting point clouds to objects, for technical/engineering designs that's probably not what you're going to be doing. The real world is rarely plumb, level, square, and/or true whereas your model will be. For example, if you're modeling a handrail it's going to be perfectly straight even if the scanned version has a noticeable bow to it. For these purposes the cloud will just be loaded into the model as a guide to trace over with a "best fit" version.
And this is probably going to go against every surveying instinct, but make sure you register the point cloud to convenient local coordinates rather than survey ones e.g. pick a close, easily identified point in the project area and call that "0, 0, 0". Non-civil engineering software doesn't deal well with large coordinate values.
Well, yeah... a couple hundred years and things aren't going line up right. Unless you're Egyptian, then you've got a few extra centuries leeway. ![]()
Design tools are built around the concept of perfect engineering, math gets really screwy when you're not dealing with straight lines. Trying to get very organic twists and curves is time consuming and can produce some very large files. Its an ongoing process to find where that "best fit" is, whether it's keeping things straight but sloped and off-angle, or as-constructed (hopefully those are different).
