Mechanical drawings, stiffeners, cutaway, right?
On the vertical section of the stiffener, a section of the stiffener should be drawn and no cross section is required on the section parallel to the stiffener.
The profile is assumed to cut the object in a cut plane, remove the part between the observer and the tangent plane, and make a projection of the remainder to the projected surface.
Section and section map, the internal structure is based on the graphic illustrations according to certain cutting direction display, profile is imaginary tangent plane of the object with a cut section, remove between the observer and the cutting plane is the part between the projection map for the remaining part of the projection surface. The profile generally used for the design of mechanical parts and engineering drawings in the supplement and complete design documents, detailed design engineering design drawings and mechanical parts, used to guide the construction and operation of mechanical processing.
