Dear All
I'm learning Daysim, and I read that we can convert from AutoCAD to Radiance
using Radout.
Can anyone provide me with available link to download Radout or send it by
email if possible.
Thanks,
Hind

You can find links and information on this page:
http://www.bozzograo.net/radiancewiki/doku.php?id=converting_models_from_autocad_to_radiance
However, all the AutoCAD scripts are rather out of date now and will
probably not work with newer versions of AutoCAD. Radiance has its own
support for OBJ files (via obj2rad or obj2mesh) so if you can convert
your CAD geometry to obj that might be a way for you.
You also can use SketchUp to load DWG files. If you don't have the Pro
version of SU you need to download a separately available plugin for
DWG/DXF support. Then you can use my own script to export to Radiance
format or directly to Daysim:
http://su2rad.googlecode.com/files/su2rad_daysim_r03.zip
And finally, if you have Rhino available there is a new tool for Rhino
that provides (among others) Daysim support:

Thomas,
I havent used all these programs before, what is the best & easier method
(program) to build a 3D model that can be use in Daysin.
Thanks a lot Thomas,
Hind

That depends on your skills with AutoCAD and which software you have available.
If you are comfortable in AutoCAD then use that to build your geometry
and find a tool that helps you to convert the geometry to OBJ. 3D Max
or Rhino can do that and it doesn't take a lot of skill to import a
file and export it in another format.
If you're new to 3D modeling anyway you can try SketchUp. Compared to
all the other 3D apps out there it is easy and intuitive to use. The
models for DAYSIM will not be too complex either so should be able to
do all your modeling in SketchUp.

Thomas

Hind,
I still use the old torad program when going from AutoCAD to Radiance. (From what I remember it is slower than radout) Unfortunately there was an autocad version check that kept it from working right on newer AutoCADs. We fixed a layer bug and changed the autocad version to work on 2007. If you are running 2010, you will have to find the comments we added and change from version 17 to whatever version 2010 is (18?).
Below are the contents of torad.lsp. You will have to replace the contents of your file with the following text. Sorry this is long, but I don't think you can attach files.
I believe torad is available from the official radiance website.
Hope that helps.

One other hint... for anyone who is entering the world of building models, I can recommend formZ. It combines CAD and modelling features and supports a broad range of 2d and 3d formats. We have used it with success to create models for Radiance via dxf (and then Schorsch's dxf2rad) and obj, and I have also verified that you could even use brlcad as a converter to keep all CAD data in IGES and convert iges-obj-Radiance (that would mean a neutral CAD standard linked to Radiance).
However the most important is to learn modeling for simulation is different from producing architectural drawings. And... I usually use a text editor for that reason, no CAD.
Cheers, Lars.
I thought Greg and John were the only maniacs who used vi to build 3D
models. Wow. In all seriousness, I have used text editors for some
models/layouts too, but only simple stuff. It definitely has its advantages,
but whenever I need to model any really complex geometry I get brain damage
trying to work out all the points.

That depends on your skills with AutoCAD and which software you have
available.
If you are comfortable in AutoCAD then use that to build your geometry
and find a tool that helps you to convert the geometry to OBJ. 3D Max
or Rhino can do that and it doesn't take a lot of skill to import a
file and export it in another format.
If you're new to 3D modeling anyway you can try SketchUp. Compared to
all the other 3D apps out there it is easy and intuitive to use. The
models for DAYSIM will not be too complex either so should be able to
do all your modeling in SketchUp.

Hi Hind,
I think that Schorsch's site has been down for awhile now. Radout has not really been actively maintained for quite some time.
Maybe if you can give us an idea of what modeling tools you have available or would like to use we can help answer relative to those....

If you want to stick with AutoCAD, have you tried TORAD.lsp that has been posted (with modification as required for your version)?
My 2 cents on other options...
I would comment that Rhino and Sketchup both produce good OBJ files that can be converted with obj2rad. You will have to start paying attention to material assignments (instead of or in addition to layers that you would have been used to in AutoCAD). Rhino is probably more expensive, but handles curved geometry much better, and has a more flexible command line interface similar to AutoCAD. Sketchup focuses on being more intuitive, but can be limited in some ways like coordinate entry. Sketchup has the su2rad plugin, and Rhino now has DIVA for additional options to get models into Radiance based simulations.
Lars has suggested FormZ, which seems comparable to Rhino but maybe less popular.
There is also Blender, which is an open source software similar to 3DSMax. It claims to export to OBJ, so may be a good try for a free test before putting money into another modeling package.

Hi Hind,
Are you using Daysim under linux or windows?
One option would be to obtain SketchUp (the free version should be fine) and see if you can import the 3ds file output from Autocad. If so you should be able to use either the su2rad or su2ds applets:
http://www.daysim.com/sketchup.html
This would be one way to get something into Daysim.

Hi,
I would agree with Christopher on Rhino and Sketchup. Blender does export obj also and does seem to be a robust application, although my main experience with it has been testing it to process obj geometry.
I think the challenge is figuring out a suitable workflow for those who need to use Autocad for whatever reason.... However the traditional options (TORAD and RADOUT) are pretty ancient at this point and have the following problems:
* TORAD - if I recall correctly this still only deals with surface
geometry which is fine if you know how to model this way...
* RADOUT - same issue as TORAD with respect to geometry and the last
version of Autocad that it could run in was Autocad 2000
For me I think that the most suitable intermediate geometry format is OBJ. It is open and there are lots of applications that can read and write the format. The challenge is figuring out how to get from Autocad to OBJ.

I would comment that Rhino and Sketchup both produce good OBJ files that can be converted with obj2rad. You will have to start paying attention to material assignments (instead of or in addition to layers that you would have been used to in AutoCAD). Rhino is probably more expensive, but handles curved geometry much better, and has a more flexible command line interface similar to AutoCAD. Sketchup focuses on being more intuitive, but can be limited in some ways like coordinate entry. Sketchup has the su2rad plugin, and Rhino now has DIVA for additional options to get models into Radiance based simulations.
Lars has suggested FormZ, which seems comparable to Rhino but maybe less popular.
There is also Blender, which is an open source software similar to 3DSMax. It claims to export to OBJ, so may be a good try for a free test before putting money into another modeling package.

Hello:
Currently, I mainly use Revit and Rhino to convert fbx to obj, following
Jack's advice. It works well. If you stick to AutoCAD, besides using torad
or dxf2rad or radout, you may also consider the following approaches.
(1) export dxf/dwg from AutoCAD
(2) import dxf to Ecotect (free of charge for student version) OR
import dwg to REVIT (free of charge for student version)
(3) export rad from Ecotect OR export fbx from Revit.
(3.1) if you get fbx file, you should use FBX converter provided by
autodesk (free) to get an older obj file and then use Rhino or others (not
sure) to rebuild surface normal because there is likely someting wrong with
the obj file directly exported by revit.
(3.2) if you export rad directly from Ecotect, you should assign
materials in Ecotect to get .mat file.
Cheers,
Jia

version of Autocad that it could run in was Autocad 2000For me I think that the most suitable intermediate geometry format is OBJ.
It is open and there are lots of applications that can read and write the
format. The challenge is figuring out how to get from Autocad to OBJ.-Jack

Hi!
First, I would recommend dxf2rad, not torad or radout.
Second, modelers ar great, but often lack precision you need for building models. You do not need nurbs for most architectural simulation, but good precision. That is why I mentioned formz, maybe Rhino offers the same. Blender is not made for this (but good for conversion and such, as it supports quite a lot of formats and geometry functions).
I had mentioned the option to use brlcad for one simple reason. Autocad is popular, but a horror for people who want to keep their project data in standard formats. They change format support from version to version and keep the dwg format closed and it's development unpredictable. Keeping only the geometry (obj) is not a good solution. So I have been looking for options to link Radiance to open and standardized formats. IGES is one, STEP another. A lot of Cad software supports these. And as brlcad can convert them into obj on the command-line, it is possible to keep all geometry in such Cad formats and convert on the fly. I think for people who want to access their projects 10 years later a great advantage, and the only reason I mention it here.
About texteditors, it depends on the project. A lot of simulation models require little detail, but high precision. And using genbox and Co not only avoids leaks, but makes sure that you control surface normal orientation. But it all depends on needed complexity of geometry and on what you want to do with yor model.
Cheers, Lars.
