Exporting CAD Model to STEP with material and appearance

[troydjEPMYB]

I am trying to export a CAD model of an electronic component to STEP. However, all bodies in the component are exported in the STEP file with default material and appearance. I thought Fusion 360 exported in STEP AP214 format which is suppose to have support for color etc.. Is this a bug with Fusion or a known limitation?

How are you assigning the colour? As a test I used 2 different Aluminium appearances and they show up in Rhino.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

.f3d file attached. When I export to STEP and then open the generated STEP file all material and appearance info is lost.

Only the color shows up, not the full appearance material.

I don't believe STEP export functionality is working properly. I created a simply rectangle shape and configured material as Aluminum with appearance polished. Exported to STEP and then opened the generated STEP file in Fusion, material and appearance lost... checking the properties of the STEP file shows that material and appearance have been changed to Steel with  appearance as opaque (245,245,246).

I'll have to experiment with this, but I believe what you are seeing in the export is the physical default material that goes along with an color. The polished look will NOT be exported.
