Hey all. First serious shot at this, so bear with some noob questions. Trying to pull in a .LAZ file to make a site model. I found a good LiDAR map of the site I need to model. File size isn't too bad. About 85MB. Here is the place I downloaded the file: https://viewer.nationalmap.gov/basic/ I search around using the term "bogachiel state park", and choose that blob. No idea of the relative scale other than it is an X,Y,Z coordinate file. And that makes sense. Shouldn't need a scale so to speak. I open it in an open-source web utility. I used this one: http://plas.io/ Realize the file is X,Y,Z format, and looks correct. It's the file I need, and it seems to be happily displayed in this web viewer. I put a 'real world' model on my file, and set the file units to Feet, and it looks correct. The viewer plops a model of the Empire State building on the cloud file as a sanity check. I say it looks about right and carry on. Create a new Vectorworks file. No templates. Drag and drop the file in. It pulls in all 23 million plus data points. Asks me what units the file is in. I select 'Feet'. Here is the rub: There doesn't seem to be an input button for "X,Y,Z" on the file import dialog. Just 'lengths' like Millimeters, centimeters, meters, feet, inches. I choose feet, because I have no idea what the software is really looking for, and the dialog makes me choose something. Cloud opens up, and it is completely out of whack. Points are all good, cloud looks correct, 3D views look correct, but the scale is way off. Whats my best bet here? I don't have a clear way to 'scale' the cloud data, nor do I think that is a good idea. I can get a general idea from a bridge and some frontage, but not enough to be accurate if I scale things. What I would like is a properly scaled version of this. If I pull a dimension along the river edge, I should see about 900' from a bridge to a turn. Instead I see a distance of about 801,000'. What am I missing here?
