Actual size of stl models

So I made a model of the same skull in Philips IntelliSpace portal and then I compared all four models.
Basically model made with 3D Slicer with correction of gentry angulation and automatic segmentation (Segment editor module) and made with IntelliSpace portal are the pretty much the same dimensions. Also, there was no much difference in dimensions of a model obtained with Mimics. These slight differences could come from the difference in treshold setting when segmenting.
Biggest deviation has the model made with manual segmentation in 3D Slicer, where there was no gantry tilt correction and the biggest difference is almost 1 mm in z-axis (hight od the skull).
Now, someone could say that 1mm is not a big deal but when you want to make a custom-made implant or any custom-made device, in some cases that is a big problem (i.e. orbital floor implant).

This is great, thanks for testing and confirming that Slicer can load these instead correctly.

Probably in the next Slicer version we’ll enable correction by default.
