Structure by Coordinates

[Anonymous]

Hi there,

we are renovating two apartment buildings, they get a prefabricated Wooden Jacket.

I guess life was easier in the '60’s if you see how straight the existing structure is.

Never mind , a surveyor will handle this next week, and he promised me he will deliver the copy by means of a spreadsheet.

I gave him the coordinates of the intersections of the gridlines by the eattext command in Autcad. He will produce me the corresponding references for each level.

So the question relates both to Revit as to Dynamo.

How do I make my model, in order to have the model “dance” according to the coordinates I get from my surveyor?

I guess You can make a script in Dynamo, to model the structural coloums & beams along a wirteframe, driven by the coordinates…If somebody has such solution, I would be happy to have a look.

But there is more to it than just the structure. I would like all the copy to get along, that’s one wall for each lateral facade, four windows in the rear facade, and two windows and two walls in the front facade.

-How do I build my model, in a “what you see is what you get” modus?

I guess aligning copy to revit gridlines is no longer usefull?

And How do I copy the copy? Now I added Structure, floors and walls to a separate Group, and pasted the copy to the 7 other floors, but I guess this is not compatible with my parametric exterior.

I can think of some possibilities.

-Separate  revit Grids,  2D,  assigned to the iterations of each level,  to be seen by Dynamo.

-I could make a list of points, assigning lines & structural framing to it, and then I should do the same thing for the existing windows, & walls too.

-Make one building level in an separate Revit file, and have them transformed while linking them 16 times in the models of the complete buildings?

-Put all the structure & other content of the outer shell  in a level to level .rfa family?  Then I cannot include system family's like walls. I can introduce non-coplanar models to represent them tough.... And then I should make an interface to connect the intersections to the overall spreadsheet that defines the position of the existing structure.

Any thoughts on good stategy?

Kind regards,

Willem

If i understand you well , you want to position the structural columns in  locations defined by survey Points..

If so , maybe you can use Dynamo to collect the survey Points from a .csv file and then place Column Family Instances in these positions...Something like this:

Hi Constantin,

that would be already a first step, but I am thinking of grouping áll the copy of the outer shell, and constrain them to the locations of the surveyor.

I see two ways;

-1.assemblying and constraining all the copy to a big parametric appartment-shell.

-2.Doing your excercise several times fort he structure, for outer walls, for windows etc.

Option 1 seems more complicated, but more powerfull then option 2.

Kind regards,

Willem
