HELLO EVERYONE :slight_smile: this is my 2nd post :wink: i m very exited to learn dynamo. I M TRYING TO RENAME ELEMENTS LIKE BEAM,COLUMN etc… as you can see in this script, it can convert element id to Mark value. so if i place first beam it will convert beam Mark value B1, 2ND BEAM name B2.etc…

So you want to renumber the beams per level based on the sequence, running the script once per level? Try inserting these into your graph immediately after the “All Elements of Category” node. [image]

Hello, these threads could maybe help: [image] Spline Intersect family node? Revit Hi there, I’m looking for a routine/node that’s able list objects that a spline passes through from start to finish. I’ve seen some methods on here where the use of bounding boxes of famili…

Hi @imran_raj1985 You need to first sort your elements by X and Y and then rename them. Below is an example. [image]

Looks like i and @Yna_Db reply at the same time :smile:

True, and your answer is excellent, as always. But different approaches could be useful anyway. I just wonder something here: waiting for an explanation over what has been done before on the topic and why it is not working in the issue that is submitted could possibly be interesting in such a forum,…

Both selecting by model line and grouping/sorting by location work for this. The “best” approach likely depends on the type of work you are doing and on the user base your script will be run by. The advantage of the select by line method are that you can quickly adjust the manor in which the select…

Therefore, I deduce from this that some explanations on the context in which the issue arises could, generally speaking, lead to shorter and more accurate answers …

THANK YOU ALL OF YOU FOR QUICK REPLY.:slight_smile: @Kulkul I have different sizes of beam in drawing. so i cant use “family type”. so i need to use “categories” and “all element of category”. and i think its beam so i cant get “point.x or point.y” value. see below image [image] so i cant go a…

[image] imran_raj1985: i think its beam so i cant get “point.x or point.y” value @imran_raj1985 One of the possible way to extract beam curves is to use OOTB “Element.GetLocation” node. You can use Curve.Endpoint or Curve.Startpoint. [image]

Imran, The FamilyInstance.Location says that it’s producing a point, but if you watch the result you will see it is producing a line. This makes sense as beams in revit are line based not point based. As a result you are feeding a line into a node that is asking for a point. Try pulling the results…

again thanks for your response.:slight_smile: i am a learner in dynamo so its take time to understand. how to work with dynamo nodes. @jacob.small can u tell me steps to achieve this goal. like u said. [image] jacob.small: Try pulling the results of the FamilyInstance.Location node into a Cur…
