How to Draw Projections of an Inclined Rectangular Plane

TL;DR

To draw the projections of a rectangular plane inclined at 45 degrees to the vertical plane, start by marking its dimensions: 50mm by 30mm. The longer side should be positioned 10mm above the horizontal plane and the shorter side 20mm in front of the vertical plane. This setup results in the front view appearing as a square due to the incline.

hello friends here in this video we are going to see a problem on projection of planes for that here is the question a rectangular plane abcd with length 50 mm and breadth 30 mm has its surface inclined to vp at an angle of 45 degree and perpendicular to hp such that the longer side bc is 10 mm above hp and shorter side a b is 20 mm in front of vp ...

Key Insights

• 🫥 Inclined planes appear as lines in projections, while their true shape may be rectangular.
• 🫵 When a rectangular plane is inclined to the VP, it will have an apparent shape of a square in the front view.

Summary & Key Takeaways

• A rectangular plane is given with dimensions of 50mm by 30mm and is inclined to the VP at a 45-degree angle, perpendicular to the HP.

• The longer side of the rectangle (BC) is 10mm above the HP, and the shorter side (AB) is 20mm in front of the VP.

• By drawing the projections, it is revealed that the front view of the inclined plane appears as a square.
