3D scanner to produce model and drawing - LARGE Scale, though

Post date: 2022-06-29 08:34:42

How do I produce a series of drawings or 3d CAD compatible models on the cheap - is it possible?

So I have a large area that has some structure attached to it (a track and some kerbing next to it) and I need to get the actual info of how big and the realistic shape of it to a guy that is producing a computer model for me of the entire facility. I see Lidar scanners are real and seem to work and are possible on ipads and iphone and stuff but it is overwhelming what they actually are capable of, so I figured I'd ask you lot. It can be done in sections but we are likely looking at several areas of a maximum size of 100 feet x 40 feet. It *looks* like I can do that with an iPad/phone and it will give me accurate enough info that way, but they all seem to be using small object examples. Does it produce larger scale options?

Is this something that can be done? My head melted looking at all the examples and they are all linked to (at best) floor plans that look pretty simple compared to what I'd need in terms of complex shapes (curved kerbs with slope up, down and a flat section on each for example). I'd need it to be accurate to within 0.5" (probably be ok), but I'd need to produce a lot of sections of the track/kerb so I am not sure if there is some limit to how far I can move the ipad/iphone before it trips out. Is there a max size for these things? Any ideas? Is there a cheap service I can use to get it scanned?
