### 2/5 — Promising!!!

I really like this app. Very useful in viewing 3D files; however, it crashes repeatedly and randomly. To the point of frustration. Initially I set it up to use one of my Google Drives but later deleted that account. The app keeps failing when I try to add a file from the Google Drive and rightfully so but I cant find an option to change to another Google Drive account. Has the potential of being an excellent app if they can resolve its crash issues and better “settings” manipulation.

### 3/5 — A good start

Faster than A360. Combines individual parts into 1 part, which is a deal breaker for me.  I will not use it and keep looking.

### 5/5 — Just what I was looking for

Was sent STP files to view. This app opens them up in seconds and displays well. Can spin image etc. works great. Thanks.

### 5/5 — Great CAD tool

*2017-03-03*

A very nice complement to my SolidWorks files on my Drive.
