<p>Hi,<br>
<br>
ok, I've had some experience with dxf-imports. I did it a couple of years ago and was quite annoyed with it. Has it been improved? <br>
What I found was that when it found a text it looked around it and if it found walls then that was it, but since you can have different thinkness on the walls and you need to find the outer limit of the outer walls, but VE stops at the inner limit and the middle of the interior walls needs to be found it makes it quite complicated to turn a normal dwg-drawing into a useful one or have you worked out a smart method of doing this?<br>
<br>
When i was referering to reliability I was thinking of heat storage (with and without false celings) and solar insolation on more complex surfaces etc. <br>
<br>
Have you had any experience with MicroFlo?<br>
<br>
Best regards<br>

<font face="Arial">Hi,<br>
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:<br>
</font>
<ul>
<ul type="disc">
<li><font face="Arial">Remove in dxf file everything except: walls,windows, doors and labels</font>
<li><font face="Arial">When you are importing the dxf. make sure, that the appropriate scale has been input.</font>
<li><font face="Arial">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 </font></ul>
</ul>
<font face="Arial">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. <br>

<font size="4" face="Roman">Hi everyone!<br>
<br>
I just joined this mail list and I'm curious about how you use this program and if you have found any issues. <br>
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. <br>
<br>
I've heard that many users import their geometry by using dxf-files. I've tried this, but I've found it somewhat complicated. <br>
Do you have any smart methods? What program do you use to create the dxf-files? Autocad?<br>
<br>
Best regards<br>
