Sometimes closing the program, opening it again, and trying again will make it work, but sometimes not.

There is one situation I've identified where I can get it to fail about 90 percent of the time. I open the program with the default reverse taper tl loaded. In the geometry display window, I split the single segment into two segments. I use the orange line to change the segment lengths, making one end longer but the other shorter while maintaining the same total length. Then I press CTRL and adjust the csa at the point that the two segments meet. Approximately 9 times out of 10, only the active segment's csa will change, but 10 percent of the time it will adjust both segments like it's supposed to.
You seem to be confusing to features here.

If two adjoining elements have the same CSA then you can hold CTRL and resize the 'shared' area and it will resize both areas.

The other feature which you quoted is where you resize the length of an element whilst holding CTRL. This will change the start area of the element you are re-sizing to maintain the same taper.

These are two different functions. Is it the Area resize one that doesn't work? I've never had an issue with it and can't recreate your error.

But then I looked a bit harder and found that I have another option (fn key and +) and that does work, so strike that request off the list.

Thank you sir.

I realize they are two separate features. The reason I mentioned them both is because if I do NOT resize the segment lengths first, then the csa resize works. BUT if I first resize the segment lengths, after that the csa resize will not work. It's really weird.

If you can't recreate this error, I can make a video screen capture while I perform these actions to show you.

I made a video of me performing the actions and showing the failure. It's a screen capture so there's no way to prove that I was pressing CTRL, but I can assure you I was. (I had to make 2 videos, since it worked fine the first time, but failed the second.)

What's your email address? I can't attach a video here.

Oh, I see what you mean now. I used the wrong quote, I quoted you talking about the length resize when I meant to quote you talking about the csa resize. It is indeed the csa resize that is the issue. Sorry for the confusion.

I'm sending the video now.

Got the video, thanks

That's very strange.. I'll see if I can find a reason for it...

I concur. I don't think this is overstatement.


There are a few glitches that need to be worked out to keep the program from falling into the "nice, but buggy" category, but with that done, I could see it's recommendations here and elsewhere becoming as ubitquitous as "Try WinISD."

You've done a great thing, Peter.

Thanks for your share! But I would be more interested in the mathematics. Where did you find your model?

p = f(ct - x) + g(ct + x)
