materials - thermal conductivity values.

Anonymous — Thu, 11 May 2023 08:53:10 GMT

In the process of assigning thermal conductivity values (BTU-ft/hr.ft2.F) to building materials.
Its seems to automatically round to 2 decimal places. That makes the values for rigid insulation and fibreglass batts at the same value! Any ideas?

Adam:

It looks like the number of displayed decimal places is controlled by Preferences > Working Units > Angle & Font Size Decimals in Dialog Boxes (for the Physical Properties in the Building Material dialog box).

maybe the ArchiCAD template file and default work environment should be set to a higher number of places to start. Seems odd that 1/64 is the default for working units, but other values are set less fine.
