Explanation / Answer

29)

False:

A few dimensions can be given be in front view but not all the dimensions

30)

True:

Full auxilary view is preferred view but if we want to represnt only a small feature of auxilary view then special case (like break auxiliary view) arises.

31)

True :

First we will find the line that has to be considered as edge view of the inclined plane.

32)

True:

Horizontal line of front view is represented as true length line in top view

33)

False:

Oblique plane is not parallel to any of the principal planes. So they cannot be represented on any of principle planes

34)

True:

We can consider the inclined plane as a plane for auxiliary view. Thus, it has at least one edge view

35)

True:

Cutting plane indicates the position where as arrow marks associated with it represents the direction

36)

True:

For clarity purposes, we may omit hidden lines unless untill they are critical

37)

False:

We can section any no of section views for information purpose. But the section view should not be sectioned again.

38)

True:

Section lines should always be bound by visible lines. They indicate the section has be separated from rest of the view

39)

False:

Section lines are 45 degree to horizontal in general, but not necessarily. In case of assembly components where more than 2 components present, we may represent the section by altering the sectioning lines to some angle other than parallel to the outline of the section.

40)

False:

Section lines should align such that they does not make 0 degrees with bounding visible lines but they can have 45 degrees in between them.
