Hi, up front I'd just like to say that I'm finding S3D a really good tool for production purposes - and I suspect that the following is purely something I have misunderstood.
The attached image demonstrates how a simple print, a tube which has a smaller tube at the top essentially, is adding an extra wall and decreasing the hole size internally by some considerable amount. The external dimension is almost perfect and whilst I could draw the difference out in Fusion, I think it would be beneficial to understand what I have done to have the internal dimension so wrong.
There's also another smaller less worrying issue with the surface not being rendered internally just I restart the infill (see photo), again that is a solid floor on the drawing and it's simply not printed. I do wonder if the fact that I have set the bottom layer for that part of the process to 0 and the top layer to 3 is perhaps causing the issue.
Could I ask the experts to perhaps indulge me by having a look at the image?
