Now it’s time to deal with the two lumps (gussets) on the wall.
Go to the Construct Menu → Select Midplane → Angle it at the seam where the base and wall meet close to the gussets → Then go to Mesh → Create Mesh Selection → Select the original body and one of the new planes.→ Go to the Solid Tab → Create Sketch
Next, identify the gussets on the mesh sketch. It’ll probably be more distinctly shaped than anything else. Sketch it. In this case, you make a triangle, then fillet its top point into a curve.
Then extrude it and select join to the rest of the model so the part is wholly connected to the model. We’ll be cutting off the excess next.
Then do a quick sketch around the bottom, extrude, and cut off the excess.
We’ll need to do the wall part differently as this gusset indents. So to do this, we will need to cut into the indent from the back.
Sketch of the newly created part’s rear → Select the Offset Tool → Click on the outline and Offset by the measured amount to create a smaller triangle → Use the Trimming Tool to cut the triangle’s bottom line → Then extend its lines down a little, and close the triangle again.
Select the middle triangle → Extrude and cut → Then rough sketch the remaining part of the rear triangle and extrude the cut to remove any unwanted pieces.
And now, repeat the process for any other gussets.
