Axle hole primitive on a Bar connection.

[Javier Orquera]

The problem is in the 3 primitives axlehole, axlehol4 and axlehol5. The inner corners should be rounded. Not 90 degrees.

Hello: if you want to keep the shape of the primitives, I propose to use the file axl5hole (in PT) and add an extension\adjacent\complementary "sub"part that I made:
