Directshape not working?

Hello, I am using revit 2017 and trying to use direct shape but it is not working. No matter what I do I get error messages. This one is the most common: Warning:
DirectShape.ByGeometry operation failed.
Element id categoryId may not be used as a DirectShape category.
Parameter name: categoryId
What does it mean? How do I get direct shape to work? I am trying to create 3D rooms so I can run an intersection to see which diffuser are in which rooms. Does that make sense?

Instead, could you consider doing it in Dynamo?
Broad steps…

  1. Get the Bounding box/Geometry of the Room Elements
  2. Get the Bounding box/Geometry of the diffusers
  3. Check for intersection

As for the Direct Shape issue, images/files would help

Revit 2017 limits the types of category a DS can belong to. I don’t have a list of all the valid categories tho…

You can’t create 3d room with direct shape any more.
It’s in the limitation list.

It’s really meaningless.

@Enes_Kaan_Karabay Thanks, at least that lets me know that Im not crazy! can you use it in 2016? Is there any other way to get the room as a 3D solid and import it back into revit?
@Vikram_Subbaiah Can you show an example please? Thanks!

Another alternative to Vikram’s solution within Dynamo:

  1. Get the location of the diffusers as a point (using Clockwork’s Element.Location node works for me)
  2. Check if the point is in the room using Room.IsPointInside (also via clockwork)

This method relies on knowing that the location point of the diffuser won’t be above the room, which might be the case if your room stops at the ceiling. You might want to make your rooms level to level first for this to work properly. I’ve done a similar workflow with Spaces instead of Rooms, but should be the same idea.

How do you tell what the nodes are looking for for inputs? I am getting error messages…

@mix First, you need to get the elements of the family type, and not just the family type. Second, you’ll need to extract the points of the elements and feed that into the points input. I’m not sure whether or not the Room.IsPointInside is setup to accept lists, but there are workarounds for that.

In the meantime see the image below. This will give you the points of your diffusers (You actually can use the native FamilyInstance.Location component here instead of the clockwork one if you want. If you use the clockwork one, you will want to use the ‘points’ output, and not the ‘isPoint’ output.

I seem to still be having difficulty. I am getting a huge list of all the rooms which is fine and returning a true/false in the huge list. How do I just extract the “true” values? Thanks!

Here is the list;

Hi, actually I had directshape working in revit 2015 with room categories when I switched from revit 2017. Then, for some reason today, while working with the same script, it suddenly stopped working for me?? Which is creepy. Is there some kind of behind the scenes updating that snached away my nice…WORKING… DirectShape node? Im what the heck??

It’s an “improvement” in 2017 API:

DirectShape API changes
Functions that treat application id and application data id as mandatory GUIDs are being phased out.

This affects:

The DirectShape.ApplicationId and DirectShape.ApplicationDataId properties should be used instead.

DirectShape.IsValidCategoryId() has been reimplemented. The new version lists categories approved for use with DirectShape. The old version listed all top-level built-in model categories.

I think I understand that, but that doesnt explain why Direct Shape wouldnt work for room categories in Revit 2015. Nor does it explain, why, it was working before lunch and then somehow decided to stop working after lunch…unless I missed something of course…

okay, I misunderstood you…

@mix If what you are doing is trying to return a room for each diffuser you can have a python node such as below (input 0 is your rooms, input 1 is your point locations for the diffusers). Note that this is fairly rough and is adapted from something that I’ve done with Spaces, so it’s not perfect code, but I think it’s along the lines of what you are going for. It will return a null if you have a diffuser that doesn’t fall within a room.

@Jared_Friedman Thanks, but ive never done python script and Im a greenhorn at best with C#. Isnt there a way to do it with dynamo nodes? Im not sure I will be able to use this…
