Fusion 360 - Poor STL triangulation, exporting to STP and importing fixes it?

[alexQQSHR]

Hi,

I have been experiencing poor STL export quality, including some geometry corruption across a number of my models. If I export directly to STL from within my design the quality is very poor, with offset vertices / polygons.

If I export the same bodies to STP and then open those in a new design, then export that to an STL with the same settings, the output quality is greatly improved.

I produce scale models for 3D Printing - this level of corruption in the STL is quite concerning.

Direct exported model on the left, export via STP on the right (both at Medium STL quality):

Any advice? I've Validated the bodies - any suggestions to avoid adding a tonne of extra work to my workflow?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Hi @alexQQSHR 

Could you try to go through those steps?

I would try the following before exporting:

Select the body/component in the browser, right-click and select Display Detail Control.

Change it from "Adaptive" to "Fixed/High".
