In the mechanical engineering drawing lines is a very important part , the pull line results determine the working drawings that we will make , and can give meaning and a specific meaning in accordance with the terms of lines and line thickness , so be careful with the line if we are going to make a picture employment .
AUTO CAD as one of the software to provide a variety of drawing the line types are stored in a specific file . AUTO CAD users can avail this facility in accordance with the requirements of the image.
Make the type of line or load line with the term only done one time only for the same type of line . AUTO CAD users can create a kind of line by line type created by one or several types of lines at once or even any type of line we load it into the image file we're working on ,
How to perform load line form is :
1 . Click on the tool bar properties for the form that is in line or number two from the left on paper by layer
2 . Click on the other line that is under the
3 . After exiting display other menu , click load
4 . At the load menu , select the desired outline shape
5 . click on OK
1 . Click on the tool bar properties to form a line number three on the left of the posts by layer
2 . Select the desired line thickness
examples of applications of this type of line according to ( ISO 128-1982 ) on the working drawings
• Line Thickness ( 0.5 mm 0.7 mm ) is used to outline objects seen directly , line edge .
• The Thin Line ( 0.25 mm 0.35 mm ) is used for the bending radius of the shadow line , line size designation , projection lines , object pointer lines , line shading , lines short flashlight ,
• The Thin Line Free ( 0.25 mm 0.35 mm ) is used to limit the view of objects or parts of slices that are not exactly on the axis .
• The Thin Line with Zig - Zag ( 0.25 mm 0.35 mm ) display the lines are long sections of the workpiece )
• Disconnect Line Thickness ( o , 5 mm 0.7 mm ) is used to outline objects that other objects in front of him blocked , obstructed line edge .
• Disconnect Line Thin ( 0.25 mm 0.35 mm ) was used to outline objects obstructed , unobstructed line edge
• Point Thin Line Strip ( 0.25 mm 0.35 mm ) are used for flashlight line , the center line of a symmetrical object , a line indicating that the workpiece can be moved
• Point Line Strip , Thick on the tip and bend ( 0.5 / 0.7 0.25 mm / 0.35 mm ) is used for cutting the line object
• Point Strip Line Thickness ( 0.5 / 0.7 0.25 mm / 0.35 mm ) is used to line the surface will get additional work .
• Strip Outline Dual point ( 0.25 mm 0.35 mm ) is used to line the adjacent objects , moving parts , gravity lines , line objects in front of the cross- cut .
