First off, your grammar is terrible. I had to read this post a few times to even understand what you're trying to say. I've edited your post in the above quote; this is how you should post to best convey your message.
Second, this post really belongs here...

Now, since we're already here, I'll attempt to answer your question. If the numbers overlap, you can always go into the options and make them smaller. In Pep Designer, click the "Settings" tab, then click "Other Settings." This opens up the Setting window. From there, click on "Others." The fourth line down, you'll see "Font size of edge ID." The smallest number it will accept is 4, but you have to type it in manually. Likely, even the smallest font size will not be small enough for some models, in which case you either just have to live with it, or turn the edge ID off.
