CAD dimensioning issues
Thread Content
The scale I use when drawing is 1:10, meaning that the actual distance is 10; should I mark 1 or 10 on the diagram?
It’s obviously 10; the drawing should be clear at a glance after being viewed, and there’s no need for the viewer to make conversions manually. By changing the scale factor of the main unit in the annotation style to 10, the scale becomes 1:10. There are other methods as well, depending on one’s preference.
1:10 means that 1 MM on the drawing corresponds to 10 MM in reality; the marking still indicates 10
The values indicated on the diagram always represent the actual dimensions; these numerical values depend only on the unit of measurement. In general, engineering drawings use mm as the unit, and the same is true for architectural plans. If the distance between the axes of a building is 3 meters, then the value shown on the plan will be 3000.
Just give it a try in practice and you’ll understand what’s going on
The actual distance should be indicated as it is; the person viewing the diagram should not have to do the conversion themselves. The scale of the markings can be determined by adjusting the scale factor.
Indicate the actual dimensions; the scale is mainly used to facilitate drawing and viewing.
Annotations are generally marked at a 1:1 scale based on the actual distance
10. The dimension marked is the actual size by default, but the marking scale can be modified.
“The \"drawing scale\" has always been a confusing issue. It can be understood in this way: when using CAD to create drawings, the units used are millimeters; for example, a dimension of 3 meters is represented as 3000. When labeling the dimensions, the value indicated is related to the unit used. In mechanical drawings, chemical plant plans, architectural plans, etc., where millimeters are the unit of measurement, the value indicated will be 3000. For drawings in the general layout discipline, the units are usually meters; if the value shown is 3, one simply needs to click on \"Annotation Style\" and then on \"Modify\", go to the \"Main Unit\" setting, and change the \"Scale Factor\" to \"0.001\".
The actual distance should be indicated as it is; the scale of the indication can be determined by adjusting the scale factor.
