Ah, yes, I get it now. You can do it easily in Inkscape. If your letter is a font that Inkscape can recognize, and it is installed on your computer, then just type the letter and adjust the size. Next, draw a rectangle the right size to cut the letter and position it where you want it. Then select the rectangle and the letter. Next, use the menu Path and select Difference and the letter should be cut in half. Then just add any additional lines and the word/name you want to add and you are pretty much done. It looks like Dick has given you an example.
