Standardization of Engineering Drawing

Standardization of Letter and Numeral

Explains.

Same .

Technical Letter and drawing number always becomes way to show the engineering drawing purposes and objectives clearly its..

Technical Letter and drawing number also becomes decoration for drawing the engineering. On that account position of drawing and also letter and number need to be arranged in such a manner so that easy to read.

the Letter and number can be erect or oblique

Standardization of Drawing Line

Drawing Line: To make ridge from form of a substance in drawing

Mirage Line: In the form of dash line with thickness of line 1/2 ordinary line weightses. Applied to make ridge something substance that is is not seen direct by ocular.

Liver Line: In the form of line “ stripe, point, stripe, point “ with thickness of line 1/2 ordinary lines. Applied to show axis a substance drawn.

Scale Line: In the form of trim lines with thickness of 1 / 2 from ordinary line weights.

Secant: This line in the form of line “ strip,titik,titik,strip” with thickness of 1/2 ordinary line weightses.

Squeezing lines

If when two lines or more different of its(the type squeezs, hence its the depiction must be executed as according to priority like following).

Drawing line ( Thick line joints, type A) Line is not seen ( line incises medium, type D) Secant ( line is having point, which dipertebal

its(the noses and place of direction transformations, type F)

Axis lines ( line is having point, type E) Line assists, measure line and hachures line ( trim

lines joints, type B).

Level of diminution

At usage of format DIN, level of diminution to the next DIN format with photocopy is 70,7%, for example from DIN A3 becomes DIN A4.

Level of enlargement

For enlargement from format DIN to format DIN which is the next larger ones, applied level of enlargement 141,4%, for example from DIN A4 becomes DIN A3. this Diminution and also enlargement arranged automatically at copier.
