how to solve it, i already ungroup and explode the models, and i cant make it more simple than this
Some of your data is of type curve. No amount of ungrouping and exploding will turn a curve into a surface. You’ll need to filter out those unsupported geometry types. One way to do this would be to run your data through a Brep or Mesh parameter. But if the curves are closed and planar that’ll actually convert them into boundary surfaces, which may not be what you want.
Hello! I’m having this same issue right now except I am only putting in a closed Brep; even when I filter it through another Brep component or a Mesh component, it still says gives me the exact same error message as in this post.
