Re: [TRNSYS-users] TRnsys3D skecthup plugin



Dear Thibaut,

Thank you for expressing your concerns. As I began using the plugin a year and a half ago, I also ran into some frustrations. Fortunately, most of these were fixed, and I learned my mistakes (I should've read the manual first!).

I love using the TRNSYS3D plugin for Google SketchUp.  I can make a building envelope in a matter of seconds and import that into TRNBuild consistently without problems. We spend some a small amount of time at our training courses in TRNSYS3D and the attendees are able to make it work for them as well, so I have no doubt that you can as well.

I have some rules of thumb for using the plugin.

1. Read the TRNSYS3D FAQ and Manual!
2. Shut off all other building plugins (OpenStudio, IES VE, etc.).
3. ONLY DRAW IN YOUR ZONE WHEN IT IS ACTIVATED (dotted line NOT blue line).
4. Make sure adjacent walls share the EXACT SAME vertices before you run the 'Match Surfaces' tool.
5. Make sure that your surfaces are the bold color (surfaces facing outward), or you will have to use the reverse surfaces tool.
6. Get familiar with isolating your zones to edit them (either with the Move tool or the Hide rest of model tool).

Yes, there are indeed glitches in programs that I may not be experiencing on my particular machine, but all of our attendees at our courses are able to get this to function.

I hope this helps. Please let me know if you have any other questions.

Best regards,

Matt Duffy

Subject: [! TRNSYS-users] TRnsys3D skecthup plugin

Dear Trnsys users,

I've recently used the TRNSYS3D sketchup plugin because I wanted to 
study a closed atrium in a building, and I wanted to see the influence 
of the detailled model of radiation, and use the multiple nodes function.

Well... The least I can say is that it is a real pain in the...

I quit, I cannot get it to work, the drawings in sketchup starts to look 
like nothing, I've lost for no reason multiple walls that became regular 
skecthup surfaces, When I import my model in TRnbuild, some adjacencies 
disappeared... And so on. I'm lost with my multiple saves; I've got a 
plugin error every time I open a model... I've tried to be the most 
meticulous while drawing, drew each zone apart and then moved it to its 
right place, did not use the matching surface tool...
I tried a very simple model, and it worked, but I see that when the 
drawing's too complicated either i'm not enough skilled, either it's 
inadequate.

Does somedy manage to be really efficient with that tool? At the present 
time I cannot imagine someone drawing faster than somebody used to enter 
values in Trnbuild!

...Which was actually the aim of defining the geometry in a CAD software...

If yes, then what is the learning curve, and how many hours do you think 
it takes to master? Any references?

Thanks in advance.

Thibaut
