First draw a 5×5 square in top view. Use Snap feature for easy use.
Then fillet the corners using Fillet command with a radius of 1
Extrude the rounded square 1 unit in another view.
Use FilletEdge to fillet edges of this polysurface.
You can change fillet radius by clicking on CurrentRadius and then enter an appropriate radius. I used 0.2
Tip : You can select all edges with a rectangle all over the polysurface.
Press enter after you select all the edges and rhino will complete the fillet.
Draw circles with radii given and then move the smallest one as seen above.
Use tangent lines to trim large circles.
Complete the trim as seen above and then use Join command to join closed curves.;
This way you will have closed polysurfaces instead of surfaces.
Without deselecting the curves use Extrude command to extrude those curves one unit.
Use FilletEdge again with a radius of 0.1 this time to fillet edges of those solids.
Polysurfaces after fillets completed.
Position newly created solids in top view as seen above.
Move them upper in z direction.
Use BooleanDifference command to subtract those solids from the base polysurface.
