Hey,

I don't know if it can be found, you can try to search from the link. Nowadays, many people draw them with a front view. I will share my "universal" elements with you.

Hey,

I have noticed that the drawing sheet and the print sheet must be the same size so that the thickness of the line and the size of the element correspond to the drawing.

I had a hard time learning the pixel division of the sheet size. Tool for determining the size of print sheets, handle for sizes 2.5 and 2.
The ISO216 definition of the number of pixels on the sheets does not give the correct sheet size on my 17-year-old plc machine, the screen is 1980x1080 @60Hz, the screen manual also mentions pix=0.265mm. The sheet size A4 is approx. 3% / 4% smaller than the sheet actually is.

After the pixel count of the image is corrected, the scale and paper size match, at least on my Win10 machine with + - 0,5-1% accuracy.

In CAD drawing, we have tried to get rid of the line thicknesses of the Tussi and stencil era (before 1980), when the main circuits were drawn with a thicker line. In general, circuit diagrams aim to use only two line thicknesses on the same page.
