Fusion 360 - Adding torus to sheet metal parts has weird flat pattern bugs!

toffypops — Wed, 07 Aug 2024 16:20:40 GMT

My problem occurs when i try to add torus to my sheet metal part with the JOIN feature.

Same problem happens with combine, it refuses to flat pattern.

Please review the video and see for yourself.

Enclosed a really simple sheet metal project where the same happens. So this is not unique to my model alone.

In the sample file, i have used 1.25mm thickness of flange, and just pulled up all the 4 sides of the flange using standard values and height, then made a sketch inside, and make torus with 28.88/2 in size, and 2.78 dia.

When you make up to 2x it works ok with flat pattern, but if you go for 3 or 4 it starts spitting out error messages and refusing to flatten.

Made an update video

Showing the flatten bug does not happen when i use 1 different side

Shows the flatten bug RANDOMLY occurs 9 out of 10 times trying to flatten using various clicks of the underside, but then randomly WORKS clicking theunderside.
