STEP export

Hi,
Is there a way to export mesh in STEP format?
Is there a way to convert mesh to be exported?
thanks for your help
my best

Hi,
Converting a mesh file to STEP format is not a simple thing to do. There are some software that provide a solution to convert mesh to CAD, but what they do under the hood is replace the mesh poligons with tiny planar surfaces, then merge them together to form a solid body. As a result, you will not get back the curved details the original CAD model had, but it may be simpler to work with the result in a CAD software.

The proper way of converting mesh files to CAD formats is called reverse engineering. Most of the time the process cannot be fully automated, however there are some software that helps finding relevant details on the mesh.
