Viewpoints with thousands of components can be slow to publish, download and to lookup in the model. We advise you to limit the number of linked components in a Viewpoint. For this reason you can choose to link visible components and/or selected components. Small Viewpoints are lightweight and fast. To prevent you from creating large Viewpoints by mistake we have built in this warning.
💡 Tip: When no components are linked to a viewpoint the whole model is shown. In combination with the use of clipping planes you can create small Viewpoints with good insights in the Issue.
