How to approach fillets

  1. Get all the planar surfaces in place.
  2. FilletSrf at the two radii you want to use.
  3. Untrim the fillets and intersect the fillet surfaces with the top and bottom planes.
  4. Loft the resulting curves (Refit option due to incompatible curves), then trim and clean up, Join.
  5. Filetedge the edges that work.The front corners do not at .25 because the radius of the edge itself there goes down to about .18
  6. Create Tangent blend curves between the edges of the fillets. The top oner needs to be adjusted so as not to bulge out too much (See the red and white curves)
  7. Trim back the surfaces
  8. Network surfaces matching for tangency.
