Worksets are not Layers and should not duplicate element categories. I donвЂ™t think hiding worksets is the best use of this element instance property. Worksets can be used to improve performance. Manage worksets and maintain the project standards for Workset use.

The object resides on a workset that is not visible in the view, that is not loaded in a linked file, that is not visible in a linked file.

The object resides on a workset that is not loaded within the project.

Why does it need an explanation, because itвЂ™s odd and un-editable?

Is the view вЂњDisciplineвЂќ set correctly?Д¬lick here for AutodeskвЂ™s description of the tool and view property, Discipline.

вЂњIs the element within the view range or is the view hiding the element and its category?вЂќ The View Range is important because not only does this range control and limit what is seen, but also what is selectable. There should be minimal scope boxes in the project. Many times, people use Scope Boxes to control the cop boundary of the view. It extends or limits the view range in a polygonal boundary. This changes the ability to see or edit the viewвЂ™s crop.ДЄ plan region is used in addition to the view crop.

The object is constrained to a scope box that is not visible in the view.

The viewвЂ™s far clip depth is not sufficient to show the object.

The object is outside the viewвЂ™s view range.

Is the missing element outside the scope of the view.

This is discussed in detail in our Revit Family Best Practices class.

The object is set to not be visible at the categoryвЂ™s detail levelД¬reate Revit families with fine detail elements on different subcategories and with different visibility graphic overrides.ДЇor example, door handles should not be visible in plan and only visible in elevation when the view is set to fine.

The object is a family and none of its geometry is set to be visible in the view type.

Is the viewвЂ™s detail level set correctly? Some families have elements that are controlled by subcategories and are set not to show at a coarse level of detail.

Overriding these properties in a view is counterproductive.

The Object Styles dialog is the best way to organize elements and there subcategories. There is a category override in the view.The objectвЂ™s category or subcategory is hidden in the view.Filters can change color, line weight, and visibility. Elements that match these criteria are selected or controlled by the property of the filter. Is there a filter applied to the view that is causing the element to be hidden?ДЇilters allow the conditional statements to query the model elements in the view.In a training class, I always say, вЂњIf you donвЂ™t like something about the view, itвЂ™s either the view property or the element property thatвЂ™s causing the issue.вЂќ Is the view range set correctly to see the particular element?.It also takes more system memory to manage element visibility overrides. ItвЂ™s most common and easier to troubleshoot. Element overrides are harder to troubleshoot and use more system resources.В Refrain from hiding elements in the view and stick with hiding the category. They check the Visibility Graphic Override dialog and the elementвЂ™s category is on. Element overrides can be confusing to some. Both hidden elements and hidden categories will be red while using this tool. Try using the вЂњReveal Hidden ElementsвЂќ tool in the view control bar. The element or itвЂ™s category is hidden in the view.Of course in Revit 2019 we were given the opportunity to temporarily override the template when the view is closed the overrides are removed and the view is once again controlled by the view template.

This way the properties controlled by the view template are not editable, without removing the template or modifying the template and making the changes global to all views defined by the template. I recommend defining the view template within the properties of the view. This would make the view properties change but will allow view property modifications. In my opinion, every view that is on a sheet should be d efined by a template. After each tip, if applicable, IвЂ™ll try to explain the methodology behind these suggestions.Д«efore we start, letвЂ™s discuss View Templates the best way to control the view, especially if itвЂ™s going to be placed on a sheet. IвЂ™ve seen and heard plenty of suggestions on what a user should or should not do to вЂњexposeвЂќ missing elements, but the following list is the most comprehensive checklist IвЂ™ve seen. People who are new to Revit are always having issues seeing everything in a project view.
