ISO 1101 on cylinder less than 170°

[[Ma...]]

Hi,

when i want to apply paralellism or TP on cylinder which is less than 170° ( center is 0,5mm above surface and from both sides are transition radii ) then it's showing problem as:

MCADGps-3006 It was not possible to compute a sufficient number of sections.

How to deal with this? Only geometry is allowing us to get results.

Thanks

As you guess, the problem is that you have a cylinder with less than 180 degrees. For such cylinder it is mathematically not possible to compute a stable center line. Therefore using  "Geometry" as standard onto a best-fit cylinder is the best approximation onto standard definition.
