Reference points: Think about how the part will be made, and how it will be inspected. Usually something will make sense. Try to keep common references between drawing views, and if possible try to base everything from points, planes, or edges that appear in multiple views.
Tolerances: Consider how the part will be made- what minimum tolerances can be held on the intended equipment and processes? What is the maximum tolerance on the individual parts that will allow the assembly to fit together and function properly? The right answers lie between those extremes.

What are Dimensional Constraint Types by GstarCAD?
IUG_DimensionConstraintGstarCAD provides you eight Dimensional Constraint types:LinearConstrains the horizontal or vertical distance between points.Linear(Horizontal)Constrains the X distance between points on an object, or between two points on different objects.Linear(Vertical)Constrains the Y distance between points on an object, or between two points on different objects.AlignedConstrains the distance between points on an object or between two points on different objects.AngularConstrains the angle between line or polyline segments, the angle swept out by an arc or a polyline arc segment, or the angle between three points on objects.RadiusConstrains the radius of a circle or arc.DiameterConstrains the diameter of a circle or arc.ConvertConvert associative dimensions to dimensional constraints.

What are variable inlet guide vanes?
The first link has a picture of some of these vanes: first column, second row. VIGVs direct air into the first rotor stage. They have the effect of improving the difference between the mass flows at operating points in the mid-range and corresponding surge points (which are catastrophic points at which flow through the stage could spontaneously reverse). Please see the second link and third.
What is camber is eot crane?
The height of the center point of the girder compared with the straight line between the two end points.
How is radiation used to check welds?
A source of gamma radiation is placed on one side of the weld, and a photographic film is placed on the other. Bubbles and weak points will appear on the film.
What are the reference or datum points on a cnc lathe machine?
depending on machine-x and z zero machine reference points are in the upper right hand corner(away from workpiece) whereas your programmable origin point used for your specific program is completely up to you.
What are the imperial and metric systems of measurement tolerancing and fixed reference points?

How important are the reference points in a coordinate system?
If the reference points are not correct, the location of any coordinate will be incorrect.
Why is it important to set the work holding device in realtion to the machine datums and reference points?
Setting the work holding device in relation to the machine datums and reference points ensures accurate and consistent positioning of the workpiece. This helps to maintain precision during machining operations, reduces errors, and ensures that parts are consistently produced to the desired specifications. Proper alignment also minimizes the need for manual adjustments and rework, saving time and improving overall efficiency.
What are useful reference points?
Reference points are used in order to easily access information that is in a larger collection of data.
What are the three main types of laser engraving machines?
There is an XY table which is where the workpiece is stable but the the laser moves around x and y points. The second one is best used for cylindrical workpieces. the third one both the workpiece and laser are still but mirrors are used.
what Navigation at sea requires the use of many points and lines to reference location and trajectory.What are the minimum points of reference needed to determine a trajectory (line)?
2 points
Why are reference points important when measuring speed?
Reference points are important when measuring speed because they provide a stationary frame of reference to compare the movement of an object. Without a reference point, it is difficult to determine if an object is moving or at what speed it is moving. By having reference points, we can accurately measure an object's speed relative to its surroundings.
What are the two basic points of reference on the surface of the earth?
The two basic points of reference on the surface of the Earth are the North Pole and the South Pole. These points represent the northernmost and southernmost points on Earth's axis of rotation, respectively.

What is the Distributor points gap?
.016 as a reference
How do we use reference points to determine whether motion has occurred?
Reference points are used to determine motion by comparing the position of an object relative to those points over time. If the object changes its position relative to the reference points, then motion has occurred. By observing the changes in the object's position relative to fixed points, we can determine its motion, speed, and direction.
