Visible and invisible geometry




I am a novice with SketchUp 2016 and am attempting to build a model of a 3 storey building with each floor saved as a different layer, when assembled the layers will touch to create the whole building.

Sometimes I get the following message when I work on a layer “Your recent operation has caused visible geometry to merge with existing geometry on a hidden layer”

Is this a problem? What do I need to do to (if anything) to prevent it happening?


Improper use of SketchUp’s Layer System is definitely a problem.

See these training videos…



Thank you, that is very helpful
