I completely missed this thread. Glad you gave the extension a try. Here's also an update: I recently published version 3.0 which can now be used also with other services like Google (tested), Anthropic, DeepSeek (untested). As a result, I also renamed the extension. Give it a try... https://alexschreyer.net/projects/openai-explorer-experimental/

Are you holding Ctrl? If so, don't. A simple tap will activate the Copy function of the Move tool. This function was updated in a maintenance release of 2021. Read the tip at the bottom left of the screen when you have the Move tool. Notice that a double tap of Ctrl activates a Stamp tool which will place copies of your object wherever you click to drop one. BTW, your forum profile shows you are using SketchUp 2016. Please update that information.
