Possible bug in export to 3MF

Question asked by Vera Skorkovska on Sep 8, 2017

I am using SolidWorks 2017 to export parts to 3MF. It seems to me there is a bug in the transformation exported in the 3MF file. In all the files I exported, the build node in the 3dmodel.model file looks something like this:

 

<build>

<item objectid="1" transform="1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 1.000000 1.000000 1.000000"/>

</build>

 

However if I'm correct, such a transformation is not an identity transformation (i.e. no transformation at all) but a translation of (1,1,1). I suppose the correct transformation if the model should not be transformed would be:

 

<build>

<item objectid="1" transform="1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000"/>

</build>

 

Is this a bug in SolidWorks or is there a setting I overlooked that would fix this? Attached there is a simple model of a box exported from SW to demonstrate the problem.

 

Thanks for any help
