Good afternoon:
I’m using Rhino to process point clouds from the iPhone Lidar scanner app Recon3D. The app returns an E57 file which I can then easily import into Rhino.
My question has to do with the settings of the default template into which and E57 opens.
The E57 point cloud is scaled by the app such that a reference dimension which is scanned along with the vehicle is a certain number of feet. When I open the E57 in Rhino, the scale is correct but Rhino always defaults to meters as the units. More interestingly, it has a default setting for the units of annotation dimensions as millimeters. When I simply drag-and-drop the E57 into Rhino the units of the Rhino file that opens with the imported point cloud switch to meters, then when I use the dimension tool to measure the characteristic dimension, it gives back a result in millimeters.
In the Rhino options, I have changed the default path for templates to be my custom path where I keep a variety of different drawing templates for new drawings. None of those templates uses meters as the default unit or millimeters as the annotation unit.
After all that, here’s my question:
What template file is used when you drag and drop and E57 file into Rhino (it’s none of the files in my template file folder) and can I replace that template with one of my own or edit it so that the default unit is feet and the dimensions are in feet?
Thanks,
Don
Hi @doncstevens,
The unit system of E57 files is meters. If you import an E57, rather than open, the point cloud will be scaled per the document’s current unit system.

Excellent. Thank you.
