Error in STL creation after Windows Update on 15 Jun 2017

[cybertrot]

Hi everyone, I realised that after today's lengthy Windows update I have a problem when exporting into STLs for 3D printing.

I've attached the STL file exported from (or created by) Geomagic of what should be a half-cube with a through-hole. The original file is also attached, as well as a png file which shows what happens in the slicer preview.

The artefact where the threaded hole becomes mostly sealed off occurs when I load the converted STL file into the slicer programs. I tried this on both Repetier-Host and Simplify 3D.

Anyone face this problem as I do and perhaps found a fix or a way around it?

Best,
Seb

And now it works.

Thanks bigseb! I'm not sure exactly what you did but that worked for me too.

Earlier this morning I found another way which was to reduce the length of the sketch profile parallel to the axis of the helix so that it is just a little shorter than the pitch. I made it with 0.1mm shorter so it was negligible. Exported it to STL as usual and it looked fine after slicing.

Appreciate any further explanations, but perfectly happy now that there is a solution and a work around.

Cheers,

Seb

That's exactly what I did. Alibre tends to misbehave if the profile height equals the pitch.

It must have been ever so slight as I didn't realise it going through the file. Thanks for that. I'll remember that the next time.
