I am having issues with Leaders and blocks. When I create a leader inside a block and connect it to an objects user attribute text it shows up correctly [image] But when I close the block edit window the text is now XXXX [image] If I go back into the block edit view it is still XXXX even thou…

Hi Simon - [image] Mr Simon Gallagher: Is it possible to do using a script? In the thread I linked to, @scottd was looking for a way to do this with a script. Note that you can script (with, Grasshopper, for example) adding leaders with text fields that refer to attributes of objects in a b…

Ah ok thank you. I don’t need the leader to be part of the block definition but I’d like to be able to try and reference an object inside a block. Essentially, I’m trying to add leaders that show the material name eg. TL-01 on a drawing layout. I’m just not very (at all) proficient in grasshopper …

I have a title block that references Document User Text and Layout User Text from the file where it’s inserted. Could you use something like the Document User Text to implement this? Say, have a Key of “WidgetMaterialAbbr” and a Value of “TL-01”? Then, in your leader inside the block, you would hav…

Ah ok, this could work. I will give it a go tomorrow! Thank you

I tried this but I need the leader text to dynamically update if I change the material on the object. Not sure it’s going to be possible if the object ID keeps changing when I edit a block

Hi Simon - [image] Mr Simon Gallagher: I’m just not very (at all) proficient in grasshopper :joy: If you are proficient in Python, I see that Scott added a script in that other link a few hours ago. For a quick Grasshopper example: [image] → Add Material Leader to Block Instances.3dm (2…

Ah your grasshopper solution looks great. I was just hoping you might be able to explain how I might be able to add additional objects into the block, with different material codes, and create new leaders? This would cover what I need. Thank you

I managed to get some more blocks created with tags. However, when I added the third block the material code overwrote one of the other tags and I’m not sure how to create a second leader if I add a new object. If you are able to help it would be great. Thank you [IMG_7350]

Hi Mr Simon, The idea here is that after changes are made you run the script, this will modify the previous iteration, removing and adding in new leaders as needed. There is also a option to use a Named Content Cache, this would leave the previously named Cache Leaders alone if need be. There are…

Ah this is great thank you. I moved my interior design team from CAD for drawings with Rhino and Twinmotion for visuals over to Revit and Twinmotion for everything . We do highly detailed interiors with a lot of custom joinery and furniture, but we are struggling with the time it takes to model in …

User Attribute Text inside a block

Rhino.Inside Revit

I made this python script for rhino which creates a block from a source object with user text and passes the text to the block.
