Revolve problem

mischl

hi there

is anyone able to see why this is going wrong?


my only hint is that if I choose add, these deviations are visible between the two parts, looking that not both have the same arc resolution.  perhaps it is only a render problem...

thanks in advance

You are trying to mix revolves and extrudes - Extrude 4 creates a very small edge at the front which is probably the issue. Stick to revolves if you can.

Just a tessellation issue. Right click the part and select edit appearance. You can then increase the tessellation value. Note that this is done for performance reasons and the geometry is in fact correct.

thank you for your saturday work and the rendering issue.
but it does not help to do the revolve properly to merge with the other part (part 1)
