Problem

Reference invisible in True Hidden Line

When True Hidden Line is used for a reference, some elements from the reference disappear from view. These elements are not covered/hidden by other elements, but are just not displayed.

Solution

Trying to do a True Hidden Line generation to Tolerance with a Tolerance smaller than the Resolution, reference elements may disappear from view. Examples: Resolution is 10000/Meter Tolerance 0.00001 or 1000/Meter and 0.0001.

Decreasing the Tolerance to a larger (more sensible) value brings the elements back to view.

In 08.11.07.101 this seems no longer an issue, as the True Hidden Line is implemented differently.
