[Bug ?] Axis System not repeating column at every intersection ?

[paullee]

Hi, anybody dropped into similar situation?

See screencapture / FC file - there are a numbers of 'missing' columns

As simple as this - create a column structure, put it in an Axis System, then strange result?

FreeCAD_0.18.16027_Conda_Py3Qt5_glibc2.12-x86_64.AppImage

forget this and try to draw a wall on the axis and tell me about the results

[FATHI RAMMAH]

just try to recompute manually

just try to recompute manually

Thanks for the hint! Juust recompute does not have!

Just found need to tweak Draft Precision to 9 or below, recompute then does the job

When Draft Precision is 10, there are missing columns

Yeah that's always a trade-off... Nothing, in the CAD world is absolutely, perfectly precise. There is always a tolerance in everything. Probably when we set the precision value to something very high, FreeCAD fails to find some intersection points. There will always be problems like that happening at one point or another, there is no single value that works for all cases.

But maybe we should warn users better about the possible consequences. With git commit 17e44f79b I added a better tooltip message...
