I am not sure if this is call counter part. here is an example:
I need to draw a calculator case. The case has two parts, upper case and lower case. Now I have the SW file of the circuit board with display and number 1 to 9 buttons. How can I open this circuit board file while drawing the upper and lower cases for reference dimension/location of the display, number buttons? So that I can draw the upper case right on top of the circuit board easy. Is there a tutorials I can learn from online? I am sure SW has this function but I am not sure what is it call.
