View has clipping disabled. It causes view to draw too many elements.

In-place family contains multiple disjoined solids. Consider splitting in several in-place families.

There are duplicate instances of the same family in the same place. Delete duplicate instances to improve performance.

Family definition contains view-specific imports. Such imports are inaccessible in the project - consider removal.

Host object contains too many cutting inserts - it may take long time to update. Consider splitting host object into smaller pieces or using stacked walls.

Interior categories are enabled in a large view. Even though these objects may be obscured and invisible, they still have negative impact on performance.

Family occupies XXX kilobytes of memory. Consider simplification of the family.

Family definition contains too many elements. Consider simplification of the family.

Family contains other families loaded into it but not used. Consider purging family document from unused families and types.

Sketch of <element> contains multiple independent loops - splitting it in few independent elements might improve performance.

Sketch of <element> has large area - it may slow down selection, drawing and geometric computations.

There are too many area boundary lines in area scheme <element> might result in increased model sizes on disk and in memory. Please investigate if area scheme is used in a proper way.

Sketch of <element> contains too many objects - it may take long time to solve.

Room Separation of <element> is not joined, might cause performance issue with room boundaries computations.

Project contains unused families and/or types. Consider purging them out.

A large view has view detail level set to medium or coarse. Generation of extraneous details harms performance.

Walls overlap. Consider embedding walls, editing their extents or profile to avoid overlapping.
