Will the same image look the same when opened in two CAD programs with different settings?

Question: Assumption 1: Person A’s CAD settings have the lines displayed in MM units. Assumption 2: Person B’s CAD settings have the lines displayed in CM units. Assumption 3: There is a CAD drawing named 111111. When this drawing is opened on Person A’s and Person B’s computers respectively, will the display be the same? What unit is used actually, and how is it measured?
I hadn’t noticed... Just give it a try, okay?
The effect when it is opened is the same; it’s the default setting
AutoCAD uses \"drawing units\", which are neither mm nor inches. It only needs to be converted when generating the output
The graphic settings in CAD are specified for each drawing; they remain the same whenever that drawing is opened. Different settings for two machines will result in different visual effects for the newly created drawings, while setting a particular display option once will ensure that all drawings display in the same way – otherwise, it would be impossible to share CAD drawings effectively.
Agreeing with the above views should be the same
CAD has its own units, which are only converted when exporting.
It’s the same; it depends on the settings used when creating the image
After reading everyone’s replies, I still don’t quite understand. First of all, how do I know what units and format he used for drawing? Secondly, AUTOCAD has its own drawing units – what are they? How to perform the conversion when generating the output, and how to check the units when viewing the image? Based on that unit? Looking forward to an answer
Aren’t dimensions indicated on the drawings? If there are no units specified, it is assumed to be mm; if it’s not mm, then the unit must be stated—this is stipulated by the drawing standards.
As far as what the original poster mentioned is concerned, the display effect is the same. For example, if you draw a line that is 10 units long in CAD, the measured length will vary depending on the unit settings. If the unit is set to mm, the length will be 10 mm; if it’s set to m, then the length will be 10 m. (This is a matter of interpretation; in reality, when using DI, only numbers are displayed, with no units shown. For example, if you measure this straight line, 10 will be displayed, but no unit will be shown.) The setting of units varies depending on the field of expertise. For example, the piping discipline is set to mm, while the general layout discipline is set to m. Different drawings in various specialties have different drawing scales (which must comply with **standards**). For example, currently, both the piping and the layout drawings show straight lines with a length of 1000 units on the computer. The drawing scale for piping-related drawings is 1:100, while the scale for overall layout drawings is 1:500; both are drawn on A1 paper. So on the two final drawings: the piping diagram shows that this line is 10 mm long on paper, which represents an actual length of 1 meter. On the general layout drawing, this line is 2 mm long on paper, representing a distance of 1 kilometer in reality.
Okay, I understand. By default, it’s MM. If it’s changed, that will be indicated. What the person above mentioned was about the printing scale; thanks for the guidance
The 12th floor expressed it very well; thumbs up. Learned* it
It’s definitely the same, right? The dimensions in the CAD file you save are fixed; they don’t change no matter which CAD software is used to open it. In other words, no matter whether the CAD drawing named 111111 is opened on Party A’s machine or Party B’s machine, its units remain the same – they are the unit values you set when creating the drawing. I wonder if the original poster understood? ?
Yes, you need to look at the image; it doesn’t really matter much when viewing it
