Re: [TRNSYS-users] TRnsys3D skecthup plugin

[Marcus <jones.0bj3@gmail.com>]

Hi Matt, 

I didn't CC the list on my response to Thibaut, so I'll weigh in on the issue now. I have to echo this frustration with the plugin! I can vouch for others that have used it as well in saying that the risk of crashing the plugin / problems in reloading models / other bugs is quite high, especially for anything above a few zones. Maybe we are using the plugin incorrectly, maybe it's specific to our machines or applications. Has anyone done any user feedback survey? 

More generally, I am wondering what the future of the plugin is. I don't understand the decision to create a new plugin that is incompatible with DOE OpenStudio, which has lots of funding and is continuously being improved. I would like to just import my OpenStudio generic .IDF or .OSM file into TRNSYS! The latest OpenStudio from NREL (0.40) is drastically better in stability and features when creating an .IDF. It can i.e. do geometry matching automatically (as the prerequisite for surface matching), which is critical for 10+ zones in a project, and future release will have ie/ radiance export. Is TRNSYS going to maintain this independant development path for TRNSYS 3d? 

More complaining: It is also cumbersome to change the geometry once the zone definitions are complete in TRNBLD. I would like to do this programmatically, in a script. This is important for parametric study or geometry optimization when analyzing hundreds of variants. Has anyone out there succeeded in using "trnsidfup.exe"? Any chance that this conversion could be made open source? I guess it's just a perl script compiled to EXE? 

Thanks! 

Marcus

Dear Matt,

First, I may have sound a little bit agressive ;-) , and I'm sorry but I was SO frustated to have lost 3 days of work before returning to the old method...

Yes I know quite all the tricks you've said, and I did read the manual, and did a small building, and I perfectly know I would have been able to do so in a training course within 2 hours.

But the problem is for a bigger building !! (even with the manual next to the keyboard...)
I think my problem is that I (still?) don't know how to draw perfectly from the first click in sketchup, and that I have to erase, cancel, etc. And then, it is a big mess.
Anyway, thanks for taking into account our concerns, I have my answer that some people manage to be efficient with Trnsys3D!

Best

Thibaut
