I know, very basic question but I'm yet to find a solution I'm satisfied with.
The attached image is an "arrow" I've drawn. See the dimension? How do I make the model reflect the fact I want that dimension to be 25'-0"?
Now I'm aware how to change the dimensions of the individual walls. I also know I can pick both walls and "click and drag" that corner. In ADT (or AutoCAD if these were lines) I could simply do a window around the "point" and stretch it down an exact distance. My problem with using Revit (I'm positive I'm overlooking an easy solution) is that for this point I can't get it to give me a temporary dimension. It will for the walls themselves, but I don't care about their length. It will as I drag it down, but it won't allow me to enter input.
Oddly, I made it twice through a Revit Level 1 textbook and it never tells me the best solution. As of now I have a workaround to get it done, but I know I've just not been instructed on an easy input feature to deal with this in my book.
Extra for good answers and understanding of Revit 101!
