Voronoi To Revit

HI CongChien, So beautiful!

Thank first1, with the help of your

Day 1 with Chameleon. Converting density logic in grasshopper into a unitized curtain wall system.

Question... When a exporting a complex curtain panel from Revit, ie one with multiple glass panels, mullions and louvers, it comes into Rhino as a single Brep or a series of meshed triangles, has anyone found a good way to gain control of it in Grasshopper besides rebuilding the geometry from its extents?

Hi, Nate Holland.

I think so：as long as put the parameters of interfer to Revit Edit Params. Don't have to rebuild the geometry in  grasshopper.

You can try using the Merge Faces command to simplify the geometry

I tried the Merge Faces as you suggest, the problem is I am exporting 775 curtain panels, each has 6 extrusions as sub panels, each extrusion has 6 sides, each side has two triangles. All of a sudden I am looking at trying to process well over 50,000 triangles into a merge face command. On the bright side, Chameleon handles the massive amount of data like a champ.  I'm curious in a future release will there be any possibly of being able to transfer and edit extrusion profiles? This could prove very powerful with masses and master planning.

Another question, I see that you can transfer walls to grasshopper with the GH Geom Transfer button, I can get my curtain wall into grasshopper, the wall geo and the grid lines both show up in grasshopper as expected, but I can't figure out what type of Revit parameters can be edited on a curtain wall. I would really like to set up custom grid spacing and offsets on a floor by floor basis.

I have to figure out how to send unmeshed geometry through the pipe and when that happens it should clean things up a bit.  You might try the Geometry Gym plugin that Jon is developing.  I think he is able to transfer nurbs.

As far as custom grid patterns, try the new Curtain Grid Generator command on the Revit side.  It will let you create multiple curtain grid systems on a curtain wall.  I'm working on extending that functionality too.

Possible bug and a future request - The rEditParams component has the opportunity to accept multiple parameters per update, but when I get into revit, the GH Edit Parameters button only allows me to update a parameter with the P0 input. (see image below) Is something not linking properly or is there something I should be doing differently? Also, in a future release would it be possible for a component similar to the rGetGeom to bring into GH the existing numeric parameters from Revit?

Hello! i was wondering if it is possibly to install Chameleon on revit Revit 2013? 

Nate, you're right that is a bug.  Will get it fixed as soon as possible.  When I get a chance I'll also see if I can get the existing number parameters to come through.

Allan - Yes you can install chameleon for Revit 2013.  Instructions are here: http://www.revitcity.com/forums.php?action=viewthread&thread_id...

How do I transfer these items to revit?

Hi Hiroshi~

VERSION 0.3.1.7 – Released 06/19/2012 ， cool！ 

Hi Hiroshi, I have been testing out the chameleon plugins. They're great and I can see lots of potential.

I have been having trouble getting the "Number" parameters to show up (i.e. the prompts in the menu) when you Place Adaptive Component on the Revit side. Is there a trick to this on the Revit end as you define your adaptive component?

Thanks bbgn.  The adaptive component needs an "number" parameter defined in it, and it may need to be an instance parameter as well.  Make sure you have that set in Revit before using the command.

Thanks Hiroshi. I did figure it out. However, it looks like it only works for the Curtain Wall Panel templates. I tried using general adaptive component on Revit 2012 and the parameters did not appear.

I have the most recent release of your plug in (downloaded two days ago)

Hello every one,

Just want to thank Hiroshi for good piece of software, here is my workflow to create "complex" Walls in Revit using chameleon the adaptive component.

Basic form for 4 walls to be created in Revit, there are 4 curves surfaces, and are divided with LunchBox Grid Tool.

Exported as adaptive components linked with the flowing families made of adaptive reference splines

this one for the first 3 walls

This one for the end one.

In Revit as adaptive Generic Models.

In Revit as walls by face

Great ! Armando.

Hiroshi,

I've come across a few requests for the plug in. I've mostly been using Chameleon to update curtain wall panels in Revit.

I built a fairly complex unitized curtain panel that I've been driving with grasshopper. When I try to pass 900 panels to grasshopper along with all of their geometry the process gets painstakingly slow. I've worked around this by swapping the panels to a glazed unit (a simple box) when I pass them to GH and then reverting to my custom curtain panel when I pass the data back from grasshopper. Is there anyway that you can pass just the GUID and a centerpoint/conerpoint from Revit to reduce the geometry grasshopper has to deal with?

Also, I'm currently passing 6-8 parameters back to Revit each time I update the panels. I have troubles remembering which order I put the parameters in sometimes which will often break the Revit curtain panel after a lengthy update. Is there any chance you could add a method for assigning which parameters are affected from the GH end?

Thanks,

Nate

Thanks Nate. I will try to accommodate when things slow down. Glad to know you have some workarounds though. The first request should be fairly easy.  The second I'm not sure I totally understand but it sounds like you want Grasshopper to know what parameters exist in the Revit family?  I think that can be done but it's a bit harder to do in a seamless, no-fuss way - i.e. without adding more steps to the process.

Hiroshi

That's a good point that the second request might cause additional work in some instances. Is it possible that on the Revit end it could remember which parameters were assigned to the GH parameters(at least during an open work session)?

Hiroshi,

Can I ask you the trick here. Which interop library did you use within Revit to create this connection? Is there any documentation anywhere on this?

Thanks,

D.

Hi Daniel,  It's using something called named pipes to transfer the data.  I posted some related code to the thread here: http://www.grasshopper3d.com/group/gh-revit/forum/topics/welcome-to...  Other than that it uses the API's of Revit and Grasshopper.

Thanks for the quick response. What is the dll library called? I did some work with Autodesk Robot. And that has a good Interop library.

Hiroshi,

I have another request that's come along. By the way the plug in is working great! Is it possible to swap out curtain wall types using a similar method. Obviously it won't be driven by a number parameter like the current setup, but I think there would be a way grasshopper could pass a type indicator (likely a string) that could then be referenced to the element ID. Thanks again.

Dear Chameleon community,  I am trying to gather up some examples of how Chameleon is being used on real-world projects.  If you are using it on a real project and wouldn't mind sharing some images and a description with me, could you please get in touch with me?  thanks!

Hiroshi, here's a post we just put up: http://lmnts.lmnarchitects.com/featured/adaptive-components/

We can't say too much about the project yet, but will be posting more in the coming months.  Thanks.

Hiroshi,

After watching the Vasari video you were a part of I decided to try moving geometry from grasshopper to Vasari with Chameleon. I can get geometry into the environment just fine, but I can't run any analysis on it because its an adaptive component not a mass. When I try to place the adaptive components into a mass family, Chameleon tells me that feature can only run in a project window. I found that I can manually place the adaptive component family in the mass family and then run the analysis. So I'm wondering if you could look into that for a future release.

Thank you,

Nate

Hello Hiroshi, I installed chameleon both in Revit and GH, but for some reason the Add-ins tab in Revit isn't showing... do you know how can I fix this?

Thanks in advance.

Hello Hiroshi,

Regards to the real projects using using Chameleon as interface between GH - Revit, I'm working on it, in an older post I put some images of a villa (part of a entire spa-hotel in Bacalar, Mexico). As soon as I get something decent to send you count with that.

The other question is regarding to Nate Holland Petition, which I address totally. The capacity to import GH points (adaptive component) in to Mass Family (or any other family) ambient. That wold be an big step to manage GH information in to Revit.

Cheers

P.S. Nate, Could you orient me which is the manual way to put the adaptive family built with Chameleon in to a mass family.

Thanks

Armando,

I should clarify my last post. I manually placed the adaptive component into the mass family, by clicking the points. I have yet to find a way to get geometry generated by chameleon into a mass family that will allow me to run Vasari analysis.

Also, Hiroshi,

I tried to transfer a Vasari lofted mass into GH, but found that even on relatively simple lofts with double curved faces, the meshing took too long to transfer effectively. Is there a way to control how many faces the geometry has when its passed from Vasari to GH?

Nate,

Hiroshi actually performed the analysis on a mass family in a .rvt file (project) while in vasari.  You just need to load your mass family into an .rvt file, and run the analysis.  Hope this helps.

-Bill

Nate,

Thanks for the clarifying, by my side I'll be searching for a solution.

Cheers

I cannot install Chameleon on Revit 2012 or 2013. When Revit starts, it says:Failed to initialize the add in Chameleon becase the assembly "Realease\ChameleonRVT.dll" does not exist. I checked the path"C documents and settings\""""""\Roaming\Autodesk\Revit\Addins\2012\Release\ChameleonRVT.dll", it does exist.

Anyone knows why?

Hiroshi-

I'm not having any luck going round trip from acquiring an adaptive component, and then pushing changes to that ac's instance parameters back into revit. When I push new instance parameter values into Revit it throws an error and doesn't change the parameter values.  Your documentation says that this only works for Curtain Panels, so I'm assuming this error is consistent with your plugin's current limitations.  Is that a good assumption?  

Thanks-

Marc

Marc,

I've had that issue a few times, usually it happens for one of 2 reasons.  1. You've deleted one of the components in Revit and Chameleon doesn't know how to find the ID. 2. You didn't pass the correct number of points/number params from Grasshopper. Use the Param Viewer to check all of your inputs into the Revit Edit Params component to make sure the count and tree structure is consistent.

Sorry guys if this question has been answered. I am fairly new to Chameleon. I am trying to import customized revit family into Grasshopper. Can anyone guide me a bit? Thanks

the gh place adaptive component is not working in my revit 2013 version. is there already a solution?

Hi, 

I am facing some problem with gbxml import component, i am on gh build 0.9.0014. "Input string was not in correct format". 

Is it a version problem ?

Thanks, 

Sudhir

I just tried this plugin,everything works fine,but at the end,when the processing bar is disappear，the revit window is locked,and I can't do anything with it.Is there anyone know what's the problem?(I use Revit 2013,Rhino5,Grasshopper 09.0056,win7)Thanks!!

Hi Hiroshi

I really would like to have the "Geometry transfer" with Mass families in Vasari. Have you any plans about make add-in for Vasari agian, or are you only focusing on Revit now?

Thanks!

Hi, i am having problems with vasari beta3 and chameleon. i have put  the Folder

"Release"

and

Chameleon.addin

into the 

C:\Users\USERNAME\AppData\Roaming\Autodesk\Vasari\Addins\2014

folder, the chameleon add in bar appears, but when ever i click anything on that bar, Varsari crashes

am i doning something wrong?

Hi, I have just installed Chamaleon but I only get the interopelability set of commands, not the simulation one and the Utilities ones.

Also, I run the installer for Revit and I don´t get the Chamaleon components under the Add-ins tab in Revit.
