Fusion 360 - How can I increase the polygons on a cylinder?

[cwalsh561]

I've designed a smokebox for a model locomotive which looks great in Fusion  but the cylinder has flats.  Is there a way I can increase the polygon count to make a smoother print?

Hi @cwalsh561 

Did you create a polygon sketch or circle sketch?

[cwalsh561]

It was a circle sketch which I extruded over the inner shell.

Do you mind sharing the model here, so we can find a solution for your issue?

Hi,

Yes of course.  It's on this link:

Hi,

unfortunately the download was not allowed or you are using a personal license that does not include this option.

Please share the file this way:

File > export > save as f3d on local drive  > attach it to the next post.

Thanks Gunther.  I am using a personal licence and so I've attached the file to this post.

Thanks for sharing the model.

Are you using Fusion 360 for printing or some other software?

Hi,

These are the results in Prusa Slicer at different resolutions.

I usually export an obj or an stl file and then slice it in Lychee slicer for the resin printer. 
The Prusa settings on the Fusion file are there just because there is no setting for Lychee slicers or, indeed, ChituBox.
Best regards,
Chris

Hi,

The result in the slicer depends on the quality of the exported file.

The exports as 3mf (STL gives the same results) were made in Fusion in the specified resolutions.
Any slicer should accept these formats.

Thanks Gunther,
I've increased the resolution as you suggested and the results in the slicer look great. 
Best regards and thanks again.
