Why would it be inappropriate to dimension to a feature on a surface that is not perpendicular to the line of sight?

couple of reasons.... if you are drawing and dimensioning with a Why_would_it_be_innapropriate_to_dimension_to_a_feature_on_a_surface_that_is_not_perpendicular_to_the_line_of_sightprogram the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way

How a Spirit level is used to ensure that a surface is level or perpendicular?
The bubble comes to centre when level.
How do you calculate coefficient of linear expansion of copper?
dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT
How does face milling differ from peripheral milling for producing flat surface?
In face milling: a) The axis of the cutter rotation is perpendicular to surface being milled b) The machining is performed by the cutting edges on both the end and outside periphery of the cutter In peripheral milling: a) The axis of the cutter rotation is parallel to the surface being machined. b) The operation is performed by the cutting edges of the outside periphery of the cutter
What is a feature control frame?
A feature control frame describes a geometric tolerance on an engineering drawing. Geometric dimensioning and tolerancing is defined by the ASME Y14.5-2009 standard. A feature control frame is basically a rectangle divided into several segments, in the following order: 1 - A geometric characteristic symbol (specifying what the tolerance type is, such as parallelism, position, surface profile, runout, etc.) 2 - The tolerance 3 - Up to three frames (if applicable) of the datums to which the tolerance is related to. Some tolerances (such as flatness) do not relate back to any datums.

Why would it be innapropriate to dimension to a feature on a surface that is not perpendicular to the line of sight?
couple of reasons.... if you are drawing and dimensioning with a computer program the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way
What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal
Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
How many dimension does a surface have?
2
A line perpendicular to a surface?
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
What surface is 90 degrees to a horizontal surface?
Perpendicular
What is meant by the phrase normal to the surface?
Normal to the surface is a vector which is perpendicular to that surface
Why does pressure force acts perpendicular to the body?
If that force is not perpendicular to the surface, then there is a component of the force that's parallel to the surface. That component would move fluid around, until there were no longer any force parallel to the surface ... and the whole force would again be perpendicular to the surface.
What is a definition of Perpendicular?
Perpendicular is a line drawn over a surface at an angle of 90 degrees.
Is the reaction force on a surface always perpendicular to the surface?
yes i presume
Why a vertical datum is alevel surface not a horizontal surface?
because the datum surface is perpendicular tothe direction of gravity at any point on it.but the horizontal surface is perpendicular to vertical at one point on it :D
Why the dimension of surface tension is MLT-2?
its not
