Changing value of curves.circlearc.angle-separation value in advanced preferences no longer appears to have any effect.

[ethnicfoodisgreat@…]

What steps will reproduce the problem?

1. Access Advanced Preferences.
2. I changed the value of curves.circlearc.angle-separation value to 1. Save changes.
3. Draw a line with three nodes and then press Shift-C to draw a curve connecting the nodes.

What is the expected result?

It used to produce a curve where the angle separation between the nodes was 1 degree.

What happens instead?

It produces a curve with the default separation angle. (I believe it is 20.)

Please provide any additional information below. Attach a screenshot if possible.

In the attached screenshot, the original line is on the left and the result of the Shift-C
command is on the right. It used to produce a much smoother curve with more nodes and only
one angular degree of separation between them.

The preference key is longer evaluated, see ticket:18847#comment:8 and following.

I think it works well for small and large circles. Do you have a special need for more "smoothness"?

[ethnicfoodisgreat@…]

Hi Gerd. No, I do not have a special need for smoother curves. I just like the look of them. Although I know some people don't like the fact it consumes more space in the database and increases display time. But if the setting is no longer honored, why not remove it?

[GerdP]

Good question. I've removed the documentation in the wiki but I never thought about removing the preference setting.
I'll have a look tomorrow.

Ok.

[skyper]

You can still create a big circle/curve and shrink it.

[ethnicfoodisgreat@…]

Right.
