Hi David

Thanks for your post. The pop-up shown in the screenshot you attached actually displays the location of the shape in relation to it's placement on the Canvas and is present on all shapes. In reference to your second question you may need to adjust your grid settings to accommodate a smaller wall size. For more information on how to use the Floor Plan Library please reference this Help Center article. I hope this helps! 

First thanks for your quick response. That's awesome. 

Second I still can't shorten a wall segment to below 9". I mimicked your setup and was able to get to 9" but once I shorten the wall to less than 9" the whole wall disappears. Is there a way I can just click on the text or wall and enter the size I want?
