I have gone for the Wedge with Edge Select tool. These are the steps I had taken.
Step 1 - (A) G + Z 1
Step 2 - G + Y 1
Step 3 - 2 (Edge Select Mode) + G + Y 2
Step 4 - 2 (Edge Select Mode) + G + Z - 2
Step 5 - 2 (Edge Select Mode) + X + Dissolve Edge (Bottom Surface)
Step - 6 The Wireframe Mode - Checked for all 6 Vertices
Final Wedge - Bottom View
Final Wedge - Side View (Num 3)
Final Wedge - Top View
Looking forward for your suggestions.
Best,
Utpal
