Hey! I noticed that, too! lol

Actually, I figured out what was actually going on when I upgraded to SU 7. For some reason (that I have yet to figure out), my defaults within 7 allow for me to see the "bold ends" of the line segments. When trying to put a tab in a curved line, I was able to see that the tab is less than 0.25" if the line segment is less than 0.25" in length. I actually don't mind this treatment in the PhlatScripT now that I know what's going on. I prefer shorter tab lengths on curved surfaces anyway. I just add extra ones if I think I need them.

I look at this situation as a hidden feature.

Good catch, Stelio!

 

I've noticed it also and have yet to find a simple work around What I've had to do is create a straight line segment the tab width plus the bit diameter in order for a proper size tab to appear on the sheet. I noticed this right off when doing 1/16 ply and a 1/32 bit, (not a pp).

BTW its on the things to fix on my dinos,,, someday If any one has already fixed a code, PM me and we'll get it straight for everyone.

Another note: a curved tab would be nice in places.

 

No biggie to me. I just tab the line right next to it like Stelio suggeted and it works fine.
This is something to keep an eye on though, because if not sometimes the tab can end up being too small and get cut right out from itself.
Another way around this is to change how many sides are in the arc or circle (this is done as soon as you select the tool). The downfall is the smoothness of the curves will diminish.

 

I'll have to give it another shot because I couldn't put two taps together and make a long tab when I ran a few tests doing dinos.
