Boolean Union Loft Shape Or Prepping Loft for 3D Printing
test_test395
Member Posts: 6 ✭
Should be a real basic one - can you please look at the following example file and let me know how I can combine the 2 parts and loft 'surface' into a single unit for export to my 3D printer?
If I select both parts + surface, it doesn't give me the option to Boolean. If I select only the two parts and try to Union, it gives: "Boolean resulted in no geometry change. The parts either do not intersect or are totally contained."
If I try to 3D Print the exported file as-is, the 3D printer doesn't seem to 'see' the surface as a solid when it goes to slice.
Thanks in advance

I think main reason for failure of the loft or boolean that you attempted was the fact that you were trying to join a surface with parts. As you observed in your slicer, it didn't recognize the loft; it can't print a surface because it has no thickness. Onshape couldn't join a surface with a part. I noticed also that the center of the circle and the center of the oval were not aligned, perhaps the reason for the nonmanifold error.
I repositioned the oval center to be aligned with the circle's center in the oval sketch. I used the outer edge of the oval part and the circle's edge for the loft with the 'Thin' option selected.
Looks like this is meant for airflow. Try seeking out information on using guides with a loft for a smoother transition between the circle and oval. - Scotty
