Create a lofted cut

I'm trying to make a loft cut out of a dome.
The dome has extruded cuts that make it look like a 12 pointed star. On
the legs of the star i'm trying to take a lofted slice off.
I keep getting the error message :

Unable to create this feature because it would result in zero-thickness
geometry

I have no clue what it means,(not that advanced wit SWX) or how to
solve it...

Can you please help?

 

Illustration of zero-thickness geometry:

Make a rectangular extruded block 10" x 20" x 5". Then cut an extruded
hole of diameter 2" placed 1" from any edge.

 

"zero thickness geometry error" occurs for example: when you have an
rectangular extruded boss on a plate, and you try to make another
rectangular extruded boss feature with a sketch which starts on the same
point which is shared with the previous feature. theoretically the resulting
body should have two extruded bosses on a plate, which have a shared and
common edge (this is also true for shared/common vertex). in this case the
distance between the two features geometries is zero and the thickness of
the resultant body at that point is zero also.
So my advice to you is to try and "shift" a few insignificant (for you)
microns the sketch or the feature parameters, so solidworks won't notice it
and will enable the creation of the feature.

The above example is principally correct for any feature type in solidworks
and in other cad systems as well.

I think you can get this type of error when your cut geometry is tangent or
very close to tangent to your existing geometry. Can you extend your part or
extend your cut so that they clearly overlap? This might help.

Type in zero thickness geometry in SWx help

 

Thank you guys!

After another hour af swearing yelling and trying i firgured it out...

The result is satisfacory!
