Does the process of drawing, linear and width requirements of what
Users questions:I'm learning nothing idle CAD drawing, but I forgot to college studied drawing the knowledge and did not know the drawing process, the linear and width requirements of what people know in detail please tell me ah, or sent me this web page can also be the main purpose ah
Experts answer: linear width thick solid line b can beSee thin solid line contour around b * 3 size counties, size limits, section lines, lead the wave line about b * 3 breaks in the boundary line, tried to double-line sectional view about the line breaks in the boundary b * 3 dotted line around b * 3 is not visible contour thin dotted lines around b * 3 axis, symmetrical crossed the center line of rough point b with specialSpecial requirements that line the surface of double-dotted lines around b * 3 imaginary projection contour, the broken thick line width b should plan the size and complexity of choices in between 0.5 ** 2mm, the width of thread about b * 3. Linewidth of recommended series: 0.18,0.25,0.35,0.5,0.7,1,1.4,2 mm References: mechanical drawing
