PicoZed SDR STEP file units wrong?

Former Member

I'm designing a carrier board for the PicoZed SDR, and tried importing the latest STEP file (08_038702d_2.STEP from 4/27/16) into Altium.  It imports, but it looks like the file shows the units as meters, but should be inches (it's ~39x too big).

The old STEP file (08_038702d_RFSOM.stp from 2/19/16) imports correctly, though it's much less detailed than the new one, so I'd like to use the new one if possible. 

Can anyone confirm this is a problem with the file, and not a bug in Altium?  Unfortunately, I don't see a way to scale the model in Altium, or I'd just do that.

Thanks,
Pat

    Let me check and get back to you.

    I just tried it in:
    - https://a360.autodesk.com/viewer (which loaded OK) and
    - http://beta.sharecad.org/en/ (which didn't work, failed with an error).

    Other than taking a long time to load the file, (I guess I shouldn't complain - it is free),

    its definitely in the wrong units. The board (which is actually 100mm x 62mm) measured 3.9m x 2.4m

    Also note - that the package dimensions look like they are based on the keep out areas, not the actual packages. (i.e. if you look at the DDR3L parts on the bottom, there are actually two parts, with space between them, not one part).

    We will try to fix it as soon as we can. Sorry for the inconvenience.
