Coordinates created as 10x expected values?

[Anonymous]

Hello... 

I'm very new to Fusion 360 and CAD software in general.  I've written a python script to generate flat representations of truncated cones (frustums) for eventual cutting on a cnc plasma table.  I do this by generating two arcs and connecting their endpoints with lines. This is all working very well but despite the point3d coordinates being correct from the script.. I end up with a shape in the UI that is 10x what it's supposed to be.

For example.. if I input a cone with a base diameter of 100mm and top of 50 with a height of 100.. I get a minor arc of 206mm and major arc of 412mm. When plotted in the UI though I get those points at 2062mm and 4124mm.  

I've verified the units are in mm.. and checked the API docs for the calls I'm using.. but I don't see any obvious reason for this. 

Thanks

Distances in the Fusion 360 API are always defined in centimeters.  You can read more about units here: http://help.autodesk.com/view/fusion360/ENU/?guid=GUID-A81B295F-984A-4039-B1CF-B449BEE893D7

Ah.. thanks for the quick reply. I knew it had to be something simple like that.. but missed that page in the docs.
