Best measuring method?

[wyattkellis]

Background: I want to more fully model an interior space for which I have some point/surface measurements. I'm unsure of how to work with the current format, so I've been trying to measure enough lengths to make a new assembly (this is probably the long way) and running into trouble.

Google Drive link to the file, also attached: (https://drive.google.com/file/d/10E_bf-S8t-iTEIIxwljSY2X7cs4az7Xd/view?usp=sharing)

Are there tricks/references for taking comprehensive measurements of an STP like this? I'd appreciate any help, thanks!

Opened your step and I have no idea what I'm looking at.

Is that some kind of scan you've done on a room?

@SharkDesign Sorry for the confusion! A FARO arm was used to get points of the space shown. They were put into Spatial Analyzer software and the surfaces were added before I got this file.  I hope these images help explain what's going on here. 

So my goal is to make a nice assembly for engineers designing parts for the existing mounts, flanges, etc.

Edit: Since posting this thread I grabbed the XYZ-coordinates and lengths of each feature. I think this way I can somewhat reconstruct the content of the STP file.
