Perhaps your CAD program will allow you to import graphics objects. You can then compose the math using Texmacs. Set the preferences using Edit --> Preferences --> Converters -> TeXmacs->HTML and check Export formulas as images. Then compose all your math in TeXmacs and use File -> Export -> Html. This will export all of your math expressions as PNG graphics files. You can then import these into your CAD program IF it supports importing graphics objects. If it does then you should be able to place these objects on the screen at the locations you require. However, if your CAD program will not import PNG (or Postscript or PDF) then I am sorry to say that TeXmacs may not be of any use for solving your problem, as Benito has commented below.

Good luck!

P.S. What operating system are you using and what is the name if your CAD program?

Dear  Miguel de Benito Delgado ,
in simple cad I can not calculate and type formula and calculations (result).

Hi, I'm afraid TeXmacs is not the right tool to draw these things. If I understand you well, what you want is to draw a schematic like the example you posted. I think you should look for some simple CAD software for this. > > Best, > --
