Скачать или смотреть DRAW THE PROJECTIONS OF PENTAGONAL PYRAMID

A pentagonal pyramid with side of base 35 mm and axis 70 mm long is lying on One of its base edges on HP so that the highest point of the base is 25 mm above HP, and an edge of the base is perpendicular to VP.Draw the projections of pyramid.

In this tutorial i m gonna to teach you about the case in which axis of solid (PENTAGONAL PYRAMID IN THIS TUTORIAL) is inclined with HP and parallel to VP OR point of solid at some distance from HP. so if the solid is at distance from HP the axis is always make some angle or inclination with HP.

When the axis of solid is inclined to one of the principal planes the true shape of the solid is not possibly seen from front and top and side view directly.
so we have to take the assumption to solve the question

This type of question is solved in two stages.

In the first stage solid axis if inclined to HP make the axis perpendicular to HP so that it becomes the case in which axis of solid is perpendicular to HP and parallel to VP.

i recommend all of you to go through the case
Axis of solid is perpendicular to HP and parallel to VP. here is the link to
