[solved] bug?

Hello Qcad,

I see something strange in a drawing. I draw an isosceles triangle. The sum of the 3 angles is 181 degrees, which is strange.

Greetings, Emiel

I use Qcad: 3.27.1.0 (3.27.1) and Windows 11 Pro

Emiel,
The sum of the interior angles of a triangle is an unbreakable rule, it will always be 180° degrees or Pi rads.
That can be exploited to find the third angle when 2 are already known for example.

An isosceles triangle with a height of 1142.5 and a base of 1280 long has a top angle of 58.512922385712765532118181015763... degrees.
That is displayed rounded to integers as 59 degrees.
The other two angles are then 60.743538807143617233940909492119... degrees each.
And those are displayed rounded as 61 degrees.
The sum of the rounded values only seems to be 181 degrees ... But the actual sum is 180 degrees for sure.

Increase your global decimal digits (precision) for angles under Drawing Preferences .. Dimensions .. Dimension settings .. Angular Dimensions
OR
Define a custom Dimension style for selected Angular Dimensions by editing the Angular decimal places property in the Property Editor.

Dear CVH,
I understand your words and after refining the range I have seen the difference. Thank you.
