How to draw certain devices
Thread Content
I would like to ask all the experts, for some equipment in the process flow, if there is no legend given in the depth regulations, how should I draw it? Is it just based on the appearance of the device? Thanks
It should be fine according to the appearance picture. After all, there are serial numbers and device names below, which should correspond to each other.
The standard point is to draw the general outline of the equipment.
According to what was said on floors 2 and 3, draw the appearance of the equipment and indicate the name on the flow chart. In order for others to understand the meaning of your graphics, the most important thing is to explain the legend on the homepage picture.
If there are regulations on HG20519-92, follow the regulations. If there are no regulations, draw a simplified diagram based on the appearance of the equipment. There is a sentence in the depth regulations that says this. Please read it carefully and look for it.
