I wanted to share a quick tip I recently discovered regarding disconnected dimension in LayOut and reconnecting them to SketchUp. When a “red” dimension won’t reconnect with the “Reconnect to Model” option on the context menu, I had been deleting it and recreating it from scratch.
I was happy to stumble on how to manually reconnect the existing “red” dimension without having to recreate it. The key is double-clicking the “red” dimension, looking for the red dot(s) and dragging it away and / or back to the correct point in the model. I attempted the screen recording below to illustrate manually reconnecting a “red” dimension in LayOut. (You may need to watch if at fullscreen to see it more clearly.)
I understand that a lot of folks here will already know this method, but I hope this tip may save others some time. I am using Pro 2021 with a classic license. LayOut runs kinda slowly on my computer.
