Initially the dim style was set to use the project settings. To check I went into the dim settings via the route highlighted below: The key is to be aware of the decimal rounding which the dim styles is applying to the angular dims in the image above. The thing is, i have seen this a few times before so i knew what was happening here. I threw a few dims on and it all appeared fine. Within the file above the first thing i looked at what the relationships of the grids to each other.
The problem seems to come because the dim tools don't appear to have ANY tolerance. How can it if the view is not perpendicular? My guess is that Revit has some element of tolerance when it comes to this.
What is odd about this is the fact that Revit actually displays your gridlines even if this is true. This pretty much ALWAYS caused by the section not being perfectly perpendicular to the gridline. To make this worse, you can see your Gridlines in section but if you try and dimension to them you get the following error message:Īs the message suggests, this can be pretty serious. For example, your section cuts perpendicular through a wall however for some reason you cant dim to the wall edges. Its symptoms include not being able to dimension elements horizontally within sections. This is an interesting issue i have come across on a number of projects now and therefore one i thought worth posting about.
