Exporting .obj .dae and .3ds files

stoferr

Hi, so I'm on a team were we work with several 3D solution, including Sketchup, 3DS, Rhino, etc, we all have our preferences and that is fine, however, I have nearly no experience in exporting Sketchup files into the other packages. Luckily, I have been issued with the Pro version of Sketchup, so I can export through that. What I need to export is .obj. .dae and .3ds files, now I have some questions.

Quality is extremely important for me when exporting to another file format, so that nothing is lost in the proces. Now, can Sketchup do that? When exporting I'm not seeing a great lot of options, which is good, but I want, as an example, the .3ds file to work as if it was natively made in 3D Max, is that possible?
This is based on nr. 1. I know that Skethup works with another type of geometry, (Faces) compared to most other solutions, that work with polygons. Now, when converting, how well does Sketchup perform here? Will my team mates have to clean up a lot of bad geometry, or..? (please note, im good at making clean geometry in Sketchup, so this question is purely about its converting abilities)
And how about circles? Sketchup works with edged circles, I know that as an example, Rhino do no such thing, there, a circle is round. Now, can Sketchup d this also, make a circle truly round, when exporting? Or how does that happen? Also, this question might as well be about everything "smoothed" in Sketchup, how will that look in other programs?
Last but not least, lines, Now, I dont use lines to simulate geometry, (like making a line stand alone, simulating a wire) but how does Sketchup handle lines when converting? What will happen to them?

Thank you for your time And if anyone know some great tutorials or tools that excell those natively in Sketchup for conversing, please let me know

I am affraid that you must redraw, circles and arc circles for rhino or other nurbs program
So in sketchup draw something for mark the center of the circle and radius or diameter! (segment + point )
Maybe on another layer ?
Here a method with free Su and free Nurbs prog in export
(freecad)STEP, IGES, OBJ, DXF, SVG, STL, DAE, IFC or OFF in import / export

draw SKETCHUP
export IGES or now DAE with the new V8
transform IGES STEP
imports inside MOI (or Rhino)
redraw circle, arc-circle MOI

Here the big green line is no needing for the arc circle!

And for arc circle in prog like Moi you have function who redraw an arc circle from just the segment to another one!
(so no need center) just the 2 little green segments are sufficient

Thank you for the answer, about those circles, once you extrude them to become cylinders, will Rhino then make them into polygons as well? Because, in that case, I can easily use cylinder from Sketchup right?

And about 3D max, does that work in the same way as Rhino, or does it also use circles/cylinders, made of polygons?

Thank you
