Hi,
I want to draw an arc with a radius exactly equal to 7.9 cm.
If I check “Snap to grid” the resulting radius of the arc jumps from 7.5 to 8.0 cm.
If I uncheck “Snap to grid”, the radius changes by steps as I drag the mouse, like 7.883 cm - 8 cm - 8.13 cm.
Hence my questions:
How can I further edit the arc, so that its radius is exactly 7.9 cm (without changing the position of the center)?
How is the drawing pitch defined ? Is there a way to define a 1 mm pitch for example?
Thanks in advance

I think that it is somehow tied to the magnification. Zoom in (bottom
left corner of window) and the precision grows. When you zoom back
out, Intaglio remembers independently of what it has to do to
accommodate the resolution on the screen.

I’m not familiar with the term “drawing pitch”.
As you may have guessed, I’m not a native English speaker, and it seems I have not chosen the correct word
I’m talking about the steps in the size of an object when you are drawing it e.g. through click and drag, and “Snap to grid” is unchecked.
E.g. if I draw a square the size (in cm) varies following this sequence:
7.726 - 7.761 - 7.796 - 8.832
hence a 0.0035 cm “pitch”.
As Schremmer guessed, it seems to be related to the magnification factor. If the zoom factor is set to 200% the variation is:
7.726 - 7.743 - 7.761 - 7.779 - 7.796 - 8.814 - 8.832
hence a twice smaller “pitch”.
So I was wondering if this could be adjusted to e.g. 0.01 cm, or any user-defined value.

This non-native English speaker would indeed have just used “step” or
possibly “stepping”.

sequence:
7.726 - 7.761 - 7.796 - 8.832
hence a 0.0035 cm “pitch”.

Well, it made sense that the precision on the screen depends on its
resolution. Hence the need for magnifying.
By the way, whenever I need a bit of precision and cannot use
Intaglio’s magic pop-up lines, I now easily magnify to 800% and often
a lot more. I am saying this because, back in my Canvas days, I can’t
remember why but I hated magnifying more than 200%. Perhaps Canvas
didn’t remember the alignment at printing time so this was an
exercise in futility but, in any case, it sure looks as if Intaglio
does.
Apple has always defined a pixel on the screen as one point (using the definition of 72 points/inch). Therefore at 100% magnification you can move the cursor by 1/72 inch increments, at 200% by 1/36 inch increments, etc. Unfortunately this doesn’t generally translate well into decimal centimeters (or inches for that matter).

Thanks for the explanation.
At 200% the increment is half the 100% increment, i.e. 1/144 inch (not 1/36).
At 400% the increment is 1/288 inch = 0.88 mm, so if I set the grid @ 0.1 mm and work at 400% I get the result I was looking for: draw objects with a 0.1 mm increment.
