When making a floor plan in CAD, what should you do first?
Thread Content
I am a beginner. Regarding the application of CAD, how should I make process flow diagrams?
When making a PID flow chart, you can first set up layers, make picture frames, make some diagrams of various pipe fittings, valves, and equipment that may be useful, set line types, etc. The easiest way is to call mature graphics and borrow the line types, blocks, etc., to get twice the result with half the effort.
If there are process drawings that can be used for reference, you can first digest other people's design content and then modify it on this basis. If not, first digest the design scope setting layers, line types (refer to the design instructions of the commander's drawing), line width, and color. This is the most basic, and then talk about the equipment, valves (refer to the design instructions of the commander's drawing) and other fixed information. Graphical block building facilitates later editing. Secondly, when making process drawings, you can also use definition blocks to create text blocks for the numbers of process pipes, valves, and equipment. It is very convenient to modify later. Then draw the floor plan or flow chart according to the actual size. Use Party A’s standard drawing frame to enlarge the fixed multiple (such as 100 times) and frame the entire drawing into this drawing. The ratio is 1: 100 accordingly adjusts the global scale marked on the line to 1: 100 The font size is the size shown on the drawing * 100 (for example, if the font height is 4.5, set it to 450). Finally, fill in the picture box, indicate the legend table and description file, and check it one last time. Haha, don’t forget to design the dividing line. It is best to find a system diagram to digest it first.
. . . I just made a mistake somewhere and the system diagram does not need to be based on the actual size. . . As long as the size and proportion are appropriate, it will be clear and beautiful.
Picture frame, layer, line type, line width, color
Is there a more detailed introduction?
The easiest way to get started: Find a reference picture and redo it yourself.
Just find a ready-made drawing and modify it according to your requirements. This will save you from having to create layers and block structures yourself.
