Increasing mesh resolution

Hi all. I’m very new to Rhino so super basic question here. I have been provided with a stp file. I want to convert it to an obj so I can work on it in another app so I’m using rhino to do this. When I export the mesh its resolution is quite low so I’m getting chunky visible polys on some curved surfaces. How can I improve the mesh density to get a smoother mesh?

When you export to obj, you will get a dialog box that allows you to change the mesh settings:

Alternatively, you can mesh the objects with the Mesh command and then export the result.
See the help file for information on the settings.

Hey wim. Thanks for the response. I have been cranking that up to the maximum but its still not enough. It’s odd because if I go to file/settings/render mesh quality, I can turn the setting up and the mesh looks really smooth but it doesn’t export at that level of detail.

There are some really good tips on generating meshes in this video tutorial series:

Hi John. Thanks a lot for the tutorials. Exactly what I needed.
