[Virtual-sim] Issues and dxf?

[Nouman]

Hi,
yes dxf files can be imported in VE and can save tons of time in drawing the building. Please take the following steps before you import any dxf into VE:


	* Remove in dxf file everything except: walls,windows, doors and labels
	* When you are importing the dxf. make sure, that the appropriate scale has been input.
	* The trick to find out scale of the drawing is, to measure a door, typically a single door is 1m, now let say the measurement comes upto be 10m it means its 1:10 scale. etc        

The calculation of VE is reliable. Only that the dynamic calculation gives us actualy true loads which some times differ from ASHRAE loads. The reason is ASHRAE does all its loads on a particualr design day. Whereas VE picks up the worse case scanario for the building. VE also has the capability to somply calculate ASHRAE loads. 


Best Regards;
Ali Nouman Khan

Hi everyone!

I just joined this mail list and I'm curious about how you use this program and if you have found any issues. 
I use it extensivly and I have a few issues with it and I'm afraid that some of the calculation methods arent that reliable. 

I've heard that many users import their geometry by using dxf-files. I've tried this, but I've found it somewhat complicated. 
Do you have any smart methods? What program do you use to create the dxf-files? Autocad?

Best regards
