I have tried searching for the solution but can’t find my answer.
I have created a simple tool, and inserted two more tools. The resulting model was then “merged” in subtools into one new tool.
I then exported that tool as an .obj file.
I imported that obj file in Rhino, in order to scale and save back out as an .stl file
BUT, the imported .obj file shows three different groups. The items aren’t merged into one object. However the same tool file in Zbrush, clearly shows it as one object.
The only way I have found that I can export it as a single item , is to unify the skin, but of course that seems to degrade the detail.
Any help please, this is driving me mad.
Ta in advance
