The User Preferences can be found under Edit -> Preferences. Here you can customize the appears of some features in the scene view.
Content Guide
The content guide helps you place objects in a good location within slide ensuring they're in a comfortable position for you and the other user viewing your document. Control visibility of the guide and the type:
- Floor - This is the default and should be used if you expect to use the document in an open space.
- Table - This guides helps you place objects above table height. This is useful if you're using your document in a conference room where the content needs to sit on or above the table.
Note: The guide rectangle is approx 2m x 3.5m, the reference human in the floor layout is 1.55m tall and 1.8m in the table layout.
Grid Settings
The grid serves as a visual reference for positioning, aligning, and scaling objects in the slide. Toggle visibility, opacity, size and whether your objects snap to the grid.
Selection Highlight Settings
The selection highlight makes it clear what you have selected, but depending on the appearance of the object the selection color can change the appearance of the object too much. Disabling or tweaking the color of the highlight can solve this issue
