Thanks again Max!

Here's a sample to look at something I saw. You may chalk it up to "don't use it that way", or it may help you refine it for the future.

In the sample, if you manually enter a value a little larger, you can preview a kindof "harder edge" output (It starts to suck the walls in a little), but the "complete output" morphs from what is shown at the preview stage...

Steps. Try enter a value of 130,,, Note the preview looks fairly neat. Press done and look at result... (A value of 120 seems to give a result like the preview of 130, etc)

Anyway. Nice job again........
