How to build a 3d geometry with curved face using abaqus cae?

Dear peers.

I am a new user to create a complex 3d model using abaqus cae 6.14-2.  For instance, the geometry has  (i)  an 3s impactor (semi-sphere with a short cylinder part on its diamter surface), (ii) a curved 3D panel, (iii) a single-lap joint with countersunk holes, etc.

Would you please give me some geometry building examples and the steps to creat these geometries?

Regards,
