Any info on how colours / appearances are supported with Inventor model uploads ? Some colours show but most do not. On a large assembly it’s a lot of rework to get the model looking similar to how it does as the Inventor assembly and drawings. It’s not expected that autodesk materials would be replicated but any info might be helpful and colours might be applied in the Inventor model with that in mind.
So the Inventor colours are brought across by the addin first trying to find the body colour, and if that is not set then getting the part colour. If the colours are applied to faces rather than the whole part I can see that might not work. Do you have an example you could send us (we only need a small assembly) where the colours are not coming across? If so can you send it to firstname.lastname@example.org ?
