Exporting simple geometry as STL is creating insane amount of triangles

Rhino

Hi Guys,

So I’m having a bit of a weird one here that i cant quite wrap my head around.

I have created these fairly simple shapes, but when i export as an STL, rhino creates an insane amount of triangles and a huge file.

I already found a work around by converting to mesh and then exporting as STL, but id like to know if any of you guys have a clue what is going on here?

Here is a sample of the file the file if you want to have a look yourself, maybe its my machine but that didnt seem very likely to me.

I get a pretty reasonable result with these settings.

Hi Kyle

Thanks for the reply, that seems to have solved it. The settings my file was trying to export to are below.

So i was curious which one was causing the grief, so I went through and changed each individually to see when it changed. It was the Maximum Aspect Ratio that was causing it, changing that to 0 gave me the below result.

This was someone else’s file i was sorting out to print. Im guessing maybe they had changed their export options on the file or something because as soon as i opened a new file to export an STL, my settings were back to default.

Thanks for your help!
