Replace identical objects with one block

[jean_durand]

Hello,

I work a lot with people who don’t use blocks…

How can I select identical objects (like hundreds) and replace them by one block definition, keeping their orientation and position.
I tried few python scripts like here

or here

but it doesn’t work

Like on this picture below, with identical lightbulbs

Thanks, that would help me a lot !

You can do this in Grasshopper, the key being finding a common plane via the geometry.

I did a similar workflow with Revit geometry here. If you post your file and Rhino version (Rhino 8 would be better in this case, no plugin req’d to make a block) we can take a look.

In-place generic models from revit

To wrap this up, here I placed a Family and adjusted the parameters of our custom family to the Height and Widths of our original in-place family. Note that one got miscategorized in orientation and has mixed up dimensions (welcome to data wrangling) The the previous Gh definition had a minor change that needs to be run first… adding the Orientation to the Direct Shape comments so we could exclude the Corners (which have too many variables and need to be delt with seperatly) [image] Panels_…

Hi,

Thanks for your reply, here is the rhino file 8.3

lightbulb_sphere.3dm

I have other models with hundres of lightbulbs, this is why I’m looking for a solution.

I’m not use to grasshopper but I can try

Here is a definition you can play around with that takes care of one layer. I’ll look at the others when I get time later today, perhaps tomorrow.
