Version 6 SR11
I have been struggling with this for a week or so. I cannot see any rational explanation. There are no bad objects.
The problem is that when I select Technical view, sometimes stray curves appear from objects which are not selected for the Detail. The stray curves are consistently the same, and sometimes they can be made to ‘go away’ by saving the file, closing Rhino, then reopening the file. That does not always work. Sometimes after that fix has worked, then subsequently making other changes to the model, the stray curves reappear. When they are displayed, the stray curves are also included in PDF output.
As you will see in the attached video, some of the stray curves relate to the ‘KN Unit 5 Pull Closed’ layer. The number of stray curves differs from time to time. Others relate to objects in the ‘East Deck’ layer. Interestingly, selecting the objects in the ‘SLA Stairs’ layer, then deleting those objects, removes the stray curves.
The stray curves cannot be selected. They appear to be ‘noise’ images.
The stray curves do not appear in Wireframe or other views.
I might be missing a point here, but if so, then I need your direction.
