Hi everyone ! ) I am a novice user, I encountered an error when tracing a room. (Probably too big)// Run-time error 13. what to do ??)

Thanks Michael - I have tested the dxf and it works fine here in a new Design Database project. 

Please check your regional settings - see Regional Settings for International Windows Versions - Hevacomp Wiki - Hevacomp - Bentley Communities

I should also mention, in case you are not aware, the latest version of these capabilities is available in OpenBuildings Energy Simulator, please see below for further info:

test25 (1).dxfHi  Shane! No, I didn't change the scale. Could you look at the file ?

Hi Michael,

Could you please check that your version number on the hevacomp main screen is exactly as shown here:
/

If so, could you please forward the project in question and I can take a look at it for you? You can upload it via logging a new Service Request.

Hi Shane ) i was Design Database but the seam error  

Hi Michael,

Did you change the scale of the floor plan when importing the DXF? Usually it automatically selects the correct one.
