SVG structure changes on import

[Anonymous]

For a current project we are designing fabric structures for 3D printing. These structures are first designing 2D in illustrator, saved as a SVG file and imported in Fusion 360 to transform it into a 3D model. However, when importing these SVG files they change structurally or disform, even though these misstructures are not in the SVG file whatsoever. Why does this morphing occur and how can I fix it? Does it have to do with some settings?
The structures created in illustrator exist out of filled objects not out of lines.

Hi,

1. occasional there are problems with fills in vector patterns
   Sometimes it helps to remove the fills and import only the outlines
2. please share such a SVG
