Edit profile of wall in Dynamo

[Rene_Fuhren]

Hi everyone,

Is it possible to edit a wall profile using Dynamo? I have some intersecting geometries which’ outline I would like to ‘project’ within the walls’ ‘edit profile’ command in order to cut openings in the wall(s)

Thanks in advance.

I had a look at using Revit API to create walls from profile before. It was just a quick proof of concept type pf work, but it is possible. Here’s a snippet of code that I put together for it:

try: errorReport = None walls = [] # check list depth # if list has sublists then process as such # check for PolyCurve class # if input is PolyCurve then implement conversion rvtCurves = Flatten(ProcessList(toRvtType, dsCurves)) profile = List[Autodesk.Revit.DB.Curve]() for i in rvtCurves: profile.Add(i) wallTypeId = wallType.Id levelId = level.Id try: walls.append(Wall.Create(doc, profile, structural)) #walls.append(Wall.Create(doc, profile, ElementId(wallTypeId), ElementId(levelId), structural)) except: pass except: # if error accurs anywhere in the process catch it import traceback errorReport = traceback.format_exc()

Now the rest of methods that actually do the work are in the attached file so have a look. I understand that its not exactly what you were looking for but might be a good place to start and learn.
Basically the answer is, yes, it is possible to edit wall’s profile (tricky) or even make a new wall from profile (less tricky), but API doesn’t make it too easy.

Good luck!

Thank you Konrad for your suggestion. Unfortunately I think this is too complex for my understanding. I am not much of a coder :(. I work with the great nodes created by people like you to the best of my abilities. Most times this suffices for what I want to accomplish. From your reply to me I understand that it is not possible to edit wall profiles with currently existing nodes in Dynamo. Hopefully in the future someone will be able to fill that void!

When I looked at this last the Revit API only allows you to create a new wall by profile, not edit an existing wall’s profile (sketch). I believe fundamentally the Revit API does not let you control existing sketches.

You might want to check out this discussion too:

Trim Revit Walls to Imported Surface

This should read the level and type and set them accordingly: DEV.WallByProfile2 I know Andreas has a nice node to read the host element of a window or door. Not sure if the API has a call for picking a new host… You might need to recreate the windows and doors just like the walls. Edit: You’re lucky :p. There’s a really easy way to re-host all those windows and doors: -Select all the windows and doors from the Revit UI -Copy them all -Delete the original walls. That will delete the doors …

(the new search is awesome)

try to get the intersect curve from element and wall. covert these curve into model line in revit. Then in wall profile editor mode, copy paste these model lines.

I just use this wall to create pattern on the wall.
hope it works for you.
