Beginner thrown in at the deep end needs help


#1

Hello, I need to populate a Revit model of a large, curved, concrete slab, (an elongated “S” on plan, and sloping in 2 directions), with a lot of patch repairs. There are about 7000 repairs, all of which are the full depth of the concrete slab, and all of which have their own unique footprint. No two are identical! I have coordinates for the footprint of each patch. Can this be done with Dynamo? At this stage, I don’t need to know how it is done, just whether it can be done.

TIA


#2

I believe so.

Start learning by completing every exercise in the primer (even the ones which feel useless - they won’t be).


#3

To be able to create geometry like that in Revit (more easily) is I believe one of the main reasons Dynamo exists in the first place.

Also: what @JacobSmall says: Long live the primer!


#4

Now I’m confused. I have been told that as there are no 2 identical shapes, this can’t be done. In effect, each one is a unique family.


#5

I wonder why you’d need to create 7000 different instances of a family for that.
Then again I might not quite understand what you want to do.

Hi @ian.alderman

Are any of these nodes familiar to you?


#7

Marcel,

no; I don’t really use Revit. I have somebody building a model on my behalf, but they are a relative novice.


#8

Paul,

they are all repairs in a concrete slab. All unique in shape and size.


#9

If they are families they are adaptive or have an instance parameter to allow them to flex.

I say IF as they could also be floors directly which could allow for easier variation in slope. In any case I think you should have the model builder ask the question instead of doing it on his behalf as they’ll at least share some of the vocabulary.


#10

could you give us the list of coordinates?

Apparently, as a new user I am not allowed to attach files.


#12

I’ve included a small sample below. They are only X and Y, but that is deliberate. The reason being that the concrete slab is at a fixed level, and no surveyor in the world could survey to an accuracy such that the coordinates coincide exactly with the top of the slab. Therefore we decided to plot the footprint of the repairs and then somehow extrude them through the slab, and trim afterwards.

These represent only 6 repairs out of a total of approximately 7000.

The space between the sets of coordinates denote separate repairs.
