Hi Dynamo Experts, I am trying to make a script that will dimension to the interior & exterior face of all walls that are intersected by a detail line with the specific type name of “_Auto Dimension”. So far I have managed to create a script that achieves this with the exception of only placing the dimensions at the wall centrelines. I feel like I am so frustratingly close! As a next step, I would like to also have this script collect and record the room name for each dimension segment underneath the dimension string. I imagine that I will need to somehow find the rooms that are intersected by each detail line and somehow filter this information into the dimensions once created. I haven’t started this yet as I would rather get step 1 working before further confusing myself. I have attached the script I have made so far and a screenshot of the sample job I am using. Any help in pointing me in the right direction would be amazing!! [image] [AUTO DIMENSION - V1.1_2024-04-07_10-38-38]

Hi @GoldCoastDrafting Take a look at this topic for placement of your Dimension lines. [image] Dimension string Revit Another way forward is to use @Alban_de_Chasteigner’s Genius Loci package… [image] Dim Wall.dyn (40.2 KB) [Capture] I think this graph works ok for a single dimension, but if you wanted to expand it you would need a ‘line’ for every ‘dimension’… so you need to start grouping sets of lines and walls according to the ones which need to be dimensioned (and ideally auto generating the lines). My graph does a bit of that, but you’d need to go further… Hope that’s of interest, Mark

In addition to the post that @Ewan_Opie suggested, look at other posts concerning dimensioning by references. In my opinion that will give you the most control for dimensioning to the edges/faces/centerlines of just about anything. For the second step, rhythm has a node called “Dimensions.GetReferenceElements”. This returns the element(s) that are being dimensioned to. From that point it’s just a matter of pulling the element name and appending that to the dimension text. [image]

Hello @GoldCoastDrafting, have You been able to solve this issue? I am tackling exactly the same problem. I can annotate one wall using the Genius Loci Wall Layer References node, which pulls the desired wall references (ext and int finish planes), however, as soon as I create a dimension across multiple walls, the script doesnt work. Any advice would be a huge help! EDIT: posted wrong screenshot, sorry. [image] [image]
