transform regions into surfaces

[passi]

Good evening, everyone!
I have a problem with autocad3d. I'm modeling a 3d structure and then I can import it into a calculation program, starting with 2d drawings. the structure is composed of flat figures and cylindrical surfaces, joined together.
Is there any way to turn "regions" into surfaces?
In the sense, a full cylinder, if exploded, is divided into various "superfici" described by a base grid. the regions, however, no. this creates problems of congruence then during the import of the model: I would need, in practice, that even the 2d regions were surfaces to make the grids of the cylindrical and flat surfaces coincide, eliminating any problems of congruence.
I don't know if I was clear, but I hope someone can solve or at least help me solve the problem.
Thank you so much!

convinsuperf, if you first impose delobj = 1 regions disappear

perfect, thank you very much, I wasn't aware of that command, I knew only superfpian!
and if I wanted the wireframe of the newly converted surface to be the same as another surface? (same distance between isolinees)

surfu and surfv are the variables that set the density in the two directions, you can also set zero.
isolinees are created in a fixed number proportional to the size of the surface, if you want to change the number because they resemble, act from the property panel.
