I'm building a simple scene with lots of cylinders (tubes) that I might want to 3d-print later on. Now I'm wondering how to retain some flexibility when it comes to the resolution, i.e. the number of vertices used to construct one cylinder. If I use to many, the performance suffers and if I use to few, it might not be possible to easily recover the roundness later on after I used boolean modifiers, I guess.
What's the usual process with Blender and what do you recommend?
