Thanks for the offer! Now I started to design letters from scratch - everything is done by
starting with boxes that have basic sizes like 3.18x3.38mm. Line widths are 0.38mm.
I know I can use typos for this but I want defined values and rather love to "carve" the letter out of the box.
Later the letters are placed in a defined distance (Mostly 1.02mm) and combined to one body using a new box.
After this step measuring with more than 4 decimals suddenly shows deviations.
I.e. the y-position of the letters did show no deviation after they were designed and aligned, measured them with 8 decimals.
But after combining them the deviations appeared beyond the 5th digit.
I had to move the letters by the deviation and re- position them by the desired value, then re-combine them
This is really strange, as I am working only with two decimals in my design anyway!
And of xourse I expect the lower decimals to be zero as well.
Same with moving, mostly only one decimal is needed for positioning and is entered manually.
But it seems that also moving causes deviations in the last three decimals.
I attached a file with the corrected letters as well with the deviated positions.
A body, originally being part of this file, but too big to attach. The body has also strong deviations when measuring
with more than 3 digits, what I did for months. Also this body never needed more than 1 decimal in 90%
of all steps.
Just for reminding: The origin of the document was a .sat import from TurboCad Mac Pro.
It was reworked hundreds of times after that in Fusion360 but maybe a sat-import, even hundreds of versions away in the past, might still cause the deviations when modelling? Like that little - long forgotten and deeply buried
line of code that makes robots go berserk in "Westworld"...?
All the best,
Herbert
