Has the STEP export settings been changed recently? When I exported a selection as STEP again, it turned out that the parts arrived as surfaces at the recipient. At first all parts were a block and the parts created as blocks. After I exploded the blocks, there were only surfaces but no solids.
About a month ago all parts arrived as solids after export.
Rhino 7.19
can you post a file we can take a look at?
Hello- you should Join the surfaces into solids (Check for naked edges as well) before exporting - that is not the same as creating blocks.

Hello Pascal. The bodys turning into blocks was just a stopgap. Here simple bodies distributed on layers. Files as 3dm, step and an image from eDrawing. You can see that the bodies have fallen apart into surfaces (green surfaces).

Hello- on export, make sure not to split closed surfaces -
-Pascal
Hello- the objects are exported, the target application is not importing fully closed surfaces - that is why that option exists. I do not know why the surfaces are separated and not closed breps in the target application, but it seems there are likely some import options available - just as Rhino’s Step import offers to join, or not, the surfaces.
