CAD drawing issues – rendering of main equipment
Thread Content
I need to draw a device diagram – does that mean every component inside and outside the main device has to be shown in the front view? Is it possible to set multiple sections on the main view to display the internal structure? This post was last edited by consumer33 on 2009-3-31 08:24]
It shouldn’t be called the main view. It should be called an overall layout diagram or an assembly diagram. The general layout or assembly drawing should show the structural features of the various main components of the equipment, the assembly connections between them, as well as the key dimensional specifications. It should also specify the technical requirements and characteristics. Some less important components do not need to be shown in the overall diagram or the component drawings; if what the poster is referring to are specifically the component drawings, then the outlines of those components can be drawn using simplified methods, along with indications of their assembly connections ； If the part diagram represents a standard component, only the standard number, name, and model are provided in the bill of materials; if it is not a standard component, then a separate part diagram for that component must be drawn.
Local sections or semi-sections along with multiple local sections can be used in the assembly drawing. Of course, it is not recommended to do this. For chemical processing equipment, the assembly drawings are usually in full or half sectional view.
What was said on the first floor is correct – not all components need to be shown in the assembly diagram. For standard components, it is sufficient to indicate the part number on the drawing, and then specify details such as specifications, material type, standard number, weight, etc. in the material list. For non-standard parts, a part drawing must be created, but it does not necessarily have to be included in the main drawing.
