Here is a problem i have been experiencing since the Tracker was introduced to Archicad. When you use the tracker to input a value the position of the mouse will affect the results.
Let's say you're drawing a line from A to B. (A and B are not Archicad hotspots just imaginary points)
And let's say they are 100 mm apart.
You click at the point A and input the length of 100.0 mm.
Now if your mouse is between the domain 99.526mm and 100.526mm.
The point B will be where the mouse is and not where the 100.0mm is.
Here is a Gif that demonstrates this issue: https://ibb.co/HGKrZv5
In the GIF i type 1,0 every time. But i get different results every time.
Now when you're dealing with one millimetre this can be seen. But when you are drawing a 3 meter wall and you mouse happens to be in the domain of 2999.526 - 3000.526m you will get the endpoint wrong.
Whats the harm? In itself its just a 0.5mm error max. but it messes up the angles of the elements!
The longer the element you're drawing the bigger the error. If you have multiple points that are misplaced like this the errors just snowball.
