Fillet bug

Anonymous — Thu, 26 May 2011 06:54:49 GMT

AC cannot fillet with radius smaller them 1 mm. If I try to input 0.7 mm, it rounds it up to 1.0 mm.
I have set it in the Working Units Dialog to use 0.1 mm.
It can measure it correctly though.

I do not think it is a bug. I rather think it is a deliberate limitation.
I mean, ArchiCAD is intended for designing buildings, not miniature items.
But I know this does not help you much.

I think it's a bug too.

1/16" is the smallest it will make a fillet even if you set the fillet for 1/64".

Now zoom in and resize the arc made with the fillet tool graphically. If you make it smaller than 1/16" it will just display the radius dimension as 0.

The radius dimension should be able to display a dimension as small as the dimension settings set in Project Preferences.

I can't imagine needing a fillet this small but the program should be consistent.

The importance of accuracy and percision with dimensions is not just for the sake of documentaion. It's also important for the sake of comparison even when precision is not important.

I had issues with this limitation when drawing up some components for a friends light fittings. Got around it by scaling (Resize - CMD-K) up by factor of 10, fillet with a radius 10 times the size required, then Resizing back down again. Same process when I had to measure to a higher accuracy (for laser cutting).
