Weird Conversions

This section lists all weird conversions to the tube type. A 'Weird' conversion indicates an exotic relationship between types which is almost certainly unintended on the part of the user. However, very occasionally these conversions make sense and allow the user to avoid the use of several components to achieve the same result. Examples in this category include conversions between planes and integers, or points and intervals.
