since updating to Rhino 7 i find myself often faced with the problem that Rhino 7 is not able to find intersections between two clearly intersecting closed Polysurfaces or Extrusions. Especially when using BooleanSplit or BooleanIntersection. When i reduce my tolerances it
s working correct but i can not adjust my tolerances each time im analyzing intersections.
My absolute tolerances in Rhino7 are 1-E06 and my angle tolerances are 0.001.
I know these are ridiculous tolerances but i often have to exchange Data between CADwork3d and Rhino so i need these tolerances. Actually i need 1-E07.
When i set my absolute tolerances in Rhino 6 to “1-E07” the units Textbox is showing me “0” but when i check sc.doc.Model.AbsoluteTolerances it`s showing me the correct Value. So except of the “0” in the units Textbox in Rhino6 everything is ok. Even with these tolerances the intersections and boolean operations are almost never failing.
When i set Rhino7 absolute tolerance to 1-E07 the Textbox is showing “0” and when i check sc.doc.Model.AbsoluteTolerances Rhino 7 is showing me “0” as well. When i then reduce the absolute tolerances to 1-E06 the textbox and sc.doc.Model.AbsoluteTolerances are showing the correct values but the intersections are failing from time to time.
Will Rhino7 be able to handle absolute tolerances like 1-E07 ?
Attached i am sending you an example file.
