Perhaps alignment if your referring to the profile and stations of the road.
the purpopse is to likemen hahahahahahaha
measuring the distances
It matters check the proportional dictionary and see that
Negative Suction Head means the pump is drawing liquid up from below its centerline. The distance between the centerline of the pump and the surface of the fluid is measured in head feet, this can be negative (below the pump) or positive (above the pump).
It depends on the question. If it is to do with bearings or orientation, the answer should be pretty obvious.
drawing for bearings and seals of front differential axle
PowerPoint has the ruler features that you can use to measure vertical and horizontal distances of the drawing area
Hi
On engineering drawings, the priority hierachy is object line, hidden line, center line. A centerline can be drawn extending beyond the physical edges of the part, a hidden line cannot. The hidden line (equally spaced short dashes) is drawn on the part instead of the centerline (alternating long dash, short dash, long dash)when the two lines are stacked in a view. If an object line, hidden line and center line are stacked in a view, the object line takes priority and is shown on the drawing. The centerline in both instances can be shown extending beyond the part edges for clarity.
measure the Circumference of both the top and bottom edges of the sleeve. measure the height of the sleeve. using a centerline draw the first Circumference(kinda of like a lower case "T") measure down the height of the sleeve along the centerline, draw in the other Circumference. connect the endpoints on the left then the right. you now have a flat drawing from which to measure your dimensions, area, etc.
PL is Poly Line which is a continuous line that while drawing it with pressing right click of the mouse you can choose to draw arch or line or . . . CL is Centerline and used in Working Drawing which is the final stage of a Drawing and has to be accurate and without mistakes. CL is used to show the center of the mail walls of each floor and while measuring, you will use the the Center to Center (c/c) dimansions instead of outer or inner surfaceof the walls. I hope this can help you
a magnetic compass shows the direction of magnetic north and bearings from ita compass is also a drawing utensil in design and technology that you can use to draw accurate circles. This has been improved by Harriet webster
