Step 1:
Create an outline of the body of the bowl in the XY plane and rotate it to get the body of the bowl

Step 2:
Create the following sketch on the XY datum plane and stretch each line separately, see the figure below for detailed stretching parameters:

Step 3:
Use the two stretched pieces (1 and 2) created in the previous step; create the following surface by using the “Through Curve” command in the surface bar, and set the constraint that the two surfaces are tangent to each other;

Step 4:
Use the “trim sheet” command to trim the surfaces created above, keeping the inner surfaces, as shown in the following figure;

Step 5:
Use the “pattern geometry” command to make a copy of the surface sheet; the operation data is shown in the following figure;

Step 6:
Select the XY plane and create a new datum plane with an offset distance of 70mm.

Step 7:
Create the following sketch on the new datum plane. Select the two edges of surfaces 1 and 2 as reference lines;

Step 8:
Use the “through curve mesh” command to create the following mesh surface;

Step 9:
Using the “pattern geometry” command, duplicate 24 surface pieces.

Step 10:
Use the “bounded plane” command to create the top and bottom slices, and use the “sew” command to sew all the slices together to get a solid part.

Step 11:
Select the rotated piece created in step 1 and offset the surface by 2mm as shown in the following figure; fill the bottom surface and sew the two surfaces together;

Step 12:
Use the “trim body” command to trim off the inner cavity of the bowl, as shown in the following figure;

Step 13:
Chamfer the necessary edges, the effect is shown in the figure below;
