Thank you fc_tofu.

FreeCAD Ver. 0.18

This is the screenshot of .stl exported from the solid part.
You can see the arrowed part which is supposed to be a smooth circle, but the resolution was lowered once I did export file to .stl format that is not fit for 3D printing.

You didnot give a sample file. So I use PartWB cylinder primitive as test example.
The topology of exported mesh is basically same as Rendering mode >Hiden line (Tesselation).

The setup of tesselation is located at Pref >Part Design >Shape View >Maximun deviation. Default value is 0.5%, you can try a lower value, 0.1% or so, to get finer display/export.

盡量用中文吧,讓其它人也可以明白和參予 ,中英夾雜也無妨 :D

各位好,我有類似的問題,我在Tinkercad畫一物件,匯出stl後要列印但不夠平滑,所以才接觸freecad,我在fc匯入後然後依上述更改設定後,看起來並沒有變得更平滑,請問該如何解決呢? 謝謝。
*使用fc版本為0.19

歡迎!

那是Tinkercad 輸出的問題。

FreeCAD 是 用 Brep ,放大多少也是平滑的。

應直接在FreeCAD 畫便成:)
