Properties for
HVAC
Sketches
There are some properties required for all HVAC components because the standard HVAC Sketches functionality expects them. These are:
DATA */rtext (Property RTEX)
DATA */Ductsizes (Property DUCT)
DATA */Detail (Property DETA)
DATA */Joints (Property JOIN)
DATA */Fixing (Property FIXI)
These properties are strings of text that are evaluated to describe the duct component.
For the example these may be:
Property RTEX
Pproperty ( 'Rectangular Threeway Y Type1' )
Property DUCT (example 900x700 to 600x700 and 500x700)
Pproperty (STR (DDESP[2] ) + 'x' + STR (DDESP[3] ) + ' to ' + STR (DDESP[4] ) + 'x' + STR (DDESP[5] ) + ' and ' + STR (DDESP[41] ) + 'x' + STR (DDESP[42] ) )
Property DETA
Pproperty ( ' Throats ' + STR (DDESP[12] ) + '; ' + STR (DDESP[13] ) + '; ' + STR (DDESP[7] ) + ' Inset ' + STR (DDESP[10] ) + ' V angle ' + STR (DDESP[63] ) )
Property JOIN (example FJ50 ; FJ40 ; FJ40)
Pproperty ( 'Joints ' + WDESP[58] + STR (DESP[68] ) + '; ' + WDESP[59] + STR ( DESP[69] ) + '; ' + WDESP[60] + STR (DESP[70] ) )
Property FIXI (In this case fixing is not relevant; this is usually for the likes of attachments)
