My, my, what a way with words! Mr. Jenkins could write a book, "How to offend and drive away people." It would be a classic. 'Lieue' was mispelled, BTW, not that PCB designers are expected to be English majors. Actually, I never went to school to learn what I do, except for one half-year electronics course in high school (vacuum tubes!), and some physics at CalTech. There are lot of experienced PCB designers who are very much against the use of four-way connections, and for good reason. >Bug's a bug's a bug, and that's what the original post endeavored to report. We agree that the disappearance of a junction is a bug. However, it should be noted that this particular bug predates CAD software. The original reason for disallowing the use of four-way junctions is that the tie dots might easily be lost in reproduction, and even if they are not lost, the eye reads a three-way junction *much* more quickly than a four-way, which resembles, too much, crossed lines. Further, there have been *other* bugs, I've seen them in Protel and in OrCAD, involving disappearing tie dots. Frankly, I'd design the software to *reject* four-way junctions. Try to make one, it would refuse (and suggest alternatives). Load one, it would flag it as an error. But, yes, it should not remove an existing junction regardless. >P.S. Draw the classical transitor amplifier. What's a "transitor"? It is true that, sometimes, a four-way junction can represent a circuit just a little more compactly than two three-way junctions. The compactness is not at all worth the potential confusion. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[email protected] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
