Importing a smooth cylinder from primitives

[SpiritOfMadMesh]

Is it possible to import a cylinder from the primitives menu which is as round as possible, so no flat faces on the side or as narrow as possible that they are hardly noticeable and the top surfaces are actually truly circular? 

I have a kind of labor intensive way to get there, but was wondering if there is an easier and mostly faster way. Right now I import a sphere, re-mesh it, make plane cut, extract circle from the cut face, extrude to desired height and then separate shells.

So far I have not come up with another solution and I hope someone here might show me the light :))

Dealing with meshes you'll never get a perfect circle. It will always be a n-polygon where it gets nearer to the ideal circle the higher the number of edges is.

There's a built in cylinder generator in SELECT/Edit/FitPrimtives.

Select a region on an existing mesh (e.g. SelectAll of the default Plane)

Run Edit/FitPrimitive with PrimitiveType = Cylinder and set MeshDensity to a high value (Note: You can get above the sliders max (64) via numerical input or dragging the slider to its max while moving the cursor slightly diagonal). This increases the number of triangles used to describe the circle. Note you might need to Remesh such a cylinder as its triangles are starched from mid to edge and the cylinder's height.

You might add a custom cylinder to the Primitives library: Generate a cylinder, select all of it and run ConvertTo/ConvertToSolidPart. MM will add this part to the last used user parts folder (Default: .../Documents/meshmixer/libraries/parts/user/My Parts). If required move the bundle (at least: something.obj, something.obj.prt and something.obj.png) of files  to the Primitives directory (.../Documents/meshmixer/libraries/parts/default/Primitives)

Thank you very much, both options were totally new to me and are both perfect!

First I will create a few shapes I use a lot and save them in the primitives folder.

The first option you mentioned also will come in handy. I keep discovering there is still plenty to learn in MM.

Thanks again!
